How to Supercharge Your Router with DD-WRT
Few routers utilize their full potential out of the box because their firmware limits their functionality. Thanks to an open-source project called DD-WRT, you can unlock your router’s potential to broadcast a stronger signal, manage network traffic, remotely access all your home computers, and a whole lot more. Here’s how to install it, set it up, and supercharge your network.
What You’ll Need
You don’t need much to get started with DD-WRT. All it takes is a little time to find the right version for your (hopefully) supported router:
- A supported router : Many popular routers released at least six months ago have DD-WRT support, but DD-WRT does not support all routers. Search the database to find out if yours is supported. Many have functional beta firmware, if not a final release, but read any notes on your router’s page to find out if you need to do anything special in order to successfully install DD-WRT.
- DD-WRT: When you look up your router using DD-WRT’s router database search (mentioned in the previous step), you’ll have a few downloads. Most routers will have a few downloads and you just want to choose the latest stable build. In some cases, like with the popular Asus RT-N66U, you may need to first flash temporary firmware to install DD-WRT. Most routers don’t require much work, but some need a little extra effort. Read your router’s page carefully so you don’t accidentally install the wrong thing and brick it.
- About a half an hour of your time to handle the above steps, install the DD-WRT firmware, and configure your newly supercharged router.
That’s it. Once you have your router and its corresponding DD-WRT firmware you can start setting it up.
Installing DD-WRT varies depending on your router, but the general instructions tend to stay the same. Here’s how it usually works:
- Log into your router’s admin page. This page lives at varying locations, but it’ll either resemble 192.168.x.x or 10.0.x.x. For example, most Linksys routers host their admin pages at http://192.168.1.1 . Consult your router’s manual for its admin address if you don’t know it.
- Go to the Admin(istration) section and choose Firmware Upgrade.
- Choose “Select File” and find your DD-WRT firmware.
- Upload it and wait for your router to update. Do not unplug or do anything to the router until it finishes updating.
Again, these instructions will differ depending on the router you choose. DD-WRT will include specific instructions for your router if you need to do anything special, so make sure you read them.
With DD-WRT successfully installed, reconnect to your network over ethernet or Wi-Fi (with a new network SSID of dd-wrt) and visit your admin page. In most cases it will still live at the same address of its predecessor (e.g. if you went to http://192.168.1.1 to upload the DD-WRT firmware, go there now). DD-WRT may request a username and password, which by default is root/admin (which you should change to your own if this happens). Newer versions will ask you to choose your own. After logging in, you’ll see the DD-WRT admin page. Now you’re ready to get started!
What You Can Do With Your New Super Router
With DD-WRT installed, you’ll have access to tons of awesome features. Let’s take a look at some of the best.
Note: You might notice that some of these features are available in existing routers that don’t run DD-WRT. Some routers offer more features than others, but DD-WRT always expands on those features even if they’re already present in the default firmware. So, don’t discount DD-WRT just because you already have certain features. DD-WRT can make them better.
Boost Your Wireless Signal
DD-WRT offers a few ways to improve your wireless signal. First, you need to pick the best wireless channel with the least interference. To do that, use the Meraki Wi-Fi Stumbler to see which channels are occupied by the fewest nearby routers. For more exact results, DD-WRT offers a bunch of tools to locate the best channel. If you’d like to take a deep dive into this process, read these instructions .
Once you know the channel you want, you have to tell DD-WRT. To do so, follow these steps:
- Choose the Wireless tab from the admin page.
- DD-WRT should select the Basic Settings sub-tab by default, but if not you should click on it.
- Find the Wireless Channel drop-down menu and select the channel you want.
- Click Save, then click Apply Settings.
Wait for the router to reboot with its new wireless channel, connect to your network, and you’ll be good to go.
DD-WRT can do more to improve your wireless signal by actually making your router transmit more powerfully. While it may seem like you’ll want to transmit as powerfully as your router allows, you might end up frying its motherboard that way. Instead, setting its transmit (Tx) power to 71 mW will give it a slight kick without any burnout. You can change by clicking the Wireless tab and then the Advanced Wireless Settings subtab. You’ll find a Tx Power setting. You may see it at 71 mW already as more recent versions change this for you, but if not you can make the change in that section.
If all of that doesn’t do it for you, there are always signal-boosting DIY projects that can help as well.
Use QoS to Prevent Bandwidth Hogging and Network Overloads
QoS (Quality of Service) is a set of rules that prevents bandwidth hogs, whether that’s a person (your roommate) or application (BitTorrent). QoS provides a lot of power and control and setting it up can get pretty detailed if you want. We’ll take a look at the basics here, but check out our full QoS guide for more information.
To get started, navigated to the NAT / QoS tab and then click the QoS sub-tab. Before you can do much, you’ll have to enable QoS (by selecting the Enable radio button) and fill in a few settings:
- WAN, LAN, or Both: Generally you’ll use QoS to handle traffic from outside your local network, so you’ll defaults to WAN (Wide Area Network). Unless you have a reason to change it, just leave this setting as-is.
- Packet Scheduler: This can be set to HTB or HFSC. HTB is the default method that uses a "token" system to manage bandwidth. Don't change this to HFSC unless you know what you're doing.
- Uplink and Downlink: Here you can set a limit for the total network bandwidth can be used on your network. If you don't want to max out your connection, you can set these speeds to less than their theoretical maximums. DD-WRT recommends 80-95% for uplink and 80-100% for downlink.
Once you've got those global settings taken care of, you can start specifying rules. DD-WRT splits these rules up into three categories: Services, Netmask, and MAC priorities. Here’s what they mean:
- Services Priority lets you set bandwidth priorities for different applications. These applications are pre-set and include everything from SMTP to BitTorrent to Xbox Live. If a particular service isn't listed, you can add it yourself.
- Netmask Priority can give bandwidth priority to a range of IP addresses. For example, if you have three computers that use the IP addresses 192.168.1.10, 192.168.1.11, 192.168.1.12, you can specify that range to receive priority. This can be useful if you want to ensure that your machines will always take priority over any guest computers that show up on your network.
- MAC Priority is a way to set which specific devices receive priority over others. Here you enter your device's MAC address (a MAC address is a unique identifying address for your computer's network adapter) and set a relevant priority.
Once you've chosen a service, IP range, or MAC address, and added it to your priorities list, you have to actually define the priority. By default the priority will be set to Standard, but you can promote it to Express or Premium to give it a higher bandwidth priority over other items on the list. These categories are good for applications that will sometimes require additional bandwidth, such as video chat and VOIP. You can also set any item to Exempt to let the app or computer use as much bandwidth as it wants and Bulk if you want it to only use bandwidth that is left over from other applications.
After you've finished adding all your devices and setting their priorities, you can save your settings and let your router reboot (if necessary). That's really all you have to do to get QoS working, but if you want to take a deeper dive you should check out our full QoS guide .
Set Up Port Forwarding to Access Your Computer from Afar
In most cases, your local network is local and cut off from the rest of the internet and you have just one IP address that's shown to the world (even though your router distributes several to your individual computers and devices locally)—your WAN IP. Port forwarding does takes a port on your WAN IP address—the one available to the rest of the web—and forwards it to a port on one of your local machines—a LAN IP address—so you or others can access a specific service on your local network when they’re connected to another one.
To give you a real-world example, web servers run on port 80 by default. If you wanted to run a web server from a machine at home, you’d open up port 80 on your WAN IP address and tell it to forward to port 80 on the LAN IP address of your local machine. Let’s say your WAN IP is 220.127.116.11 and the LAN IP of your desktop computer—the one you want to use as a web server—is 192.168.1.104. When someone goes to http://18.104.22.168 in a web browser (HTTP assumes you want to use port 80) they’ll get forwarded to the web server on your local machine and see whatever site you set up.
Setting up port forwarding is pretty straightforward, but before you get started you need to know what ports you want to open up. Most of the time, you'll set up port forwarding on an as-needed basis—say after you've set up a new service on your computer, like a web server. Sites like PortForward.com can help, as they provide a handy list of common ports for specific services . You can use this list to check which ports you need to open for whatever services you want to make available from outside your home network.
Once you know which port you want to open, click on the NAT / QoS tab in DD-WRT and then the Port Forwarding sub-tab. Once there, click the Add button to create a new port forwarding rule and fill out the following:
- Application - The name of the application you're forwarding this port for. You can use any descriptive text you want—this field is here to help you remember why you set this up; like the name suggests, you normally want to use the name of the application you're setting up port forwarding for. I also include my computer's name along with the service, since I forward ports for the same applications on different computers. This helps me quickly find the rules should I need to change them later on.
- Port to - "Port to" is the port on your local IP address. If you were setting up VNC for a local computer, you'd fill this in with 5900 as that's the port number VNC uses.
- Port from - "Port from" is the port on your external IP address. Generally you'll also enter the same port as you would in the "Port to" field. This works just fine when you're configuring only one machine for one type of service. But say you wanted to be able to remotely access two or more computers using VNC. If you used 5900 on a single, external IP address they would be in conflict. The router would see a request for port 5900 and not know which local IP address should handle that request since the port forwarding table has two. To solve this problem, you can use the standard port for one and not for the other—kind of like an apartment building has a single address but multiple apartments. As you can see in the sample routing table above, Grey's "Port from" is set to 5900 while Hunter's "Port from" is set to 5901. If you try to use VNC normally on my external IP address, you'll be asked to log in to Grey because it uses the standard port. If you want to access Hunter, however, you can easily do so by just using port 5901 instead of the default. This way you can set up identical services with a single external IP address without conflicts.
- Protocol - This is where you specify whether or not your service uses the TCP protocol, UDP protocol, or both. When you look up your ports you'll also want to make note of the protocols used. In most cases it will just be TCP.
- IP Address - This is where you specify the LAN (local area network) IP address of the computer you want to use for this port forwarding rule. You can easily find this information in your computer's network settings. The IP address will generally be in the 192.168.x.x or 10.0.x.x format. Because these IP address are generally dynamic (meaning they can change), you'll want to either set up static IP addresses or DHCP reservations. More information on that is available below.
- Enable - You need to check this box to enable the port forwarding rule. If you don't check it, you'll still be able to save the rule but it won't be active or function in any way.
When you’re done adding a port forwarding rule, click Save. When you’re done adding all of your rules, click Apply Settings. These are just the basics of port forwarding, and you can do quite a bit more with DD-WRT. For more information, read our port forwarding guide .
These features just scratch the surface of what you can do with DD-WRT. If you want to learn more, you’ll find tons of tutorials over at the DD-WRT Wiki . It’s not only a great resource for DD-WRT router setup and administration, but networking info as well. Whether you stop here or learn more, enjoy your new super router that cost you nothing to upgrade.

How to Port a Landline to a Cell
By Andrea Ruiz
When you first set up cell phone service, your mobile carrier may automatically assign you a new phone number by default. However, if you're making the change from a land line to a mobile phone, you don't have to lose your old phone number in the switch. The Federal Communications Commission has a federal program in place that enables users to port their old land line phone numbers to their new mobile accounts -- with a few restrictions and considerations.
Porting a Phone Number
The FCC's Wireless Local Number Portability (WLNP) program grants you the right to keep your phone number should you wish to start using another telephone service provider, as long as both numbers are in the same geographical location. For example, you can change phone service providers in the same city and keep your number, but you can't port your number to another service provider in a new city that has a area code different from that of your current number.
Transferring a Phone Number to a Wireless Account
The ability to port phone numbers from one local phone service to another includes wireless phone services. Most mobile phone carriers allow you to transfer your existing land line telephone number to your mobile phone service's account for use on your mobile phone when you set up your wireless account. You may be asked to verify ownership of the number, but typically the wireless carrier will do most of the work for you. While the transfer process may take some time depending on your carrier, in this way, you may be able to enjoy uninterrupted phone service when transferring service from a land line to a cell phone account.
Call Forwarding as a Temporary Alternative
If you only want to port your land line service temporarily, you can use call forwarding. Many land line service providers allow users to forward incoming calls to another phone number. This feature may be part of your service already, or you may have to contact your phone service provider to enable it on your account. Every service activates call forwarding in slightly different ways, but typically you must enter a code in your land line phone followed by the phone number to which you want your calls forwarded. When you no longer want your calls forwarded to your mobile phone, you can disable call forwarding using your service provider's code for that as well.
Limitations and Considerations
Some mobile carriers charge an additional one-time setup fee when setting up your service if you want to port an existing number onto your account. Call-forwarding services may also incur an additional fee when you enable them on your land line if the feature isn't already part of your phone service. Also, when you port a phone number from a land line to a cell phone, you only transfer the phone number itself, and none of its associated services. You will have to set up voice mail on your new account, and will likely no longer have access to your land line account's voice mail box.

From DD-WRT Wiki
When the WRT is used as an Access Point (AP) or repeater (WDS), the WAN port can easily be configured as a normal LAN port.
[ edit ] Adding WAN Port to LAN Switch to use as an additional, normal LAN port
Note: Steps are true for firmwares current as of the author date of this article. v2.4, post SP2 firmwares. These steps were done with build 12307 (2009 06 17). Other firmware builds of DD-WRT have the same or very similar steps.
- Open up the Web Interface to your DD-WRT Device
- Set WAN 'Connection Type' to Disabled.
- Down the Basic Setup page, the option WAN Port appears. Check the box 'Assign WAN Port to Switch'.
The WAN port is now the same as the other LAN ports.

Assign WAN Port To LAN Switch
In DD-WRT under Client or AP modes -- where the wired Ethernet WAN port is not used -- the port may be assigned to the LAN switch with a simple GUI checkbox selection of "Assign WAN port to switch."
Can this be done in OpenWRT? If yes, how does one do it?
Yes, you simply need to change the switch configuration accordingly (remove the wan portfrom the wan vlan and adding it untagged to the lan one). Unless you really need the port, I'd usually suggest to ignore it though.
yes change switch connfiguration In AP mode WAN port is required unless you are using radio as uplink
make a network bridge with all the physical ports and name it wan make Lan network withonly wirelss interface in it
check for the relevant changes in firewall.sh done
Thank you slh and arjunet. I want to assign the WAN port to the LAN switch only because it can be done. As an exercise. Is there any reason not to do this?
Can anyone give me detailed directions on what sequence of commands (settings) to use? Moreover, I am completely ignorant of the methods and syntax of the command line mode. Can anyone direct me to a router command line 101?
Yes you can do that ..if it is what you want to achieve
It depends on your hardware. Some hardware has a separate Ethernet port on the CPU that goes directly to the WAN port on the back of the router. In that case you would go to the network configuration, physical settings, and move the WAN ethernet port from the wan network to the lan network.
In other cases, especially gigabit routers, all the ports on the back go through a hardware switch. There you would go to the Network-Switch page and turn off the WAN port in the WAN VLAN, and turn it on (untagged) in the LAN VLAN with the other LAN ports.
DDwrt tries to simplify configuration by giving the user preset "modes" for common use cases. OpenWrt is more toward total flexibility. You can set anything to do anything, even if that is going to totally break it. You can add or edit a file anywhere in the filesystem rather than having only a "nvram" database.
If you're using command line, the most direct approach is to edit the config files. Search the OpenWrt wiki and find the UCI pages. These explain the options possible in each file.
Please understand the question before answering it. OP needs to use the WAN port as a LAN port. They do not need to configure all the ports as WAN. There is a marked difference in the config.
There are two reasons not to do this, unless you really need the fifth port to be usable as an additional LAN port.
- you can get it wrong, soft-bricking the device or creating a number of subtile problems that might haunt you for quite a while
- if the WAN port is a dedicated ethernet interface and not connected to the same hardware switch as the LAN ports, you'd need to bridge it with the switch - this would required the data going through the SOC's CPU for the bridging to work, creating a serious bottleneck in terms of performance
If you are aware of the consequences, the technical implications (dedicated interface vs switch port) and actually need an additional LAN port, there's no reason not to do this - but it shouldn't be done "just 'cause" by a beginner.
dumb AP examples , but read and heed the above.
Thank you for taking the time with the caveats. I'll take my time. Nevertheless I live by the precept "no guts, no glory." After all, how does one move from beginner to experienced without doing what can be done even if it need not be done? This stuff should be not all that hard. I mean, really, how arcane can it be?
A month of serious study and experimentation should be more than enough to graduate beyond the clueless novice level. This isn't rocket science. At least it does not appear to be. I was building DEC PDP11s and LSI-11s linked on fiber-optic serial highways which were in turn connected to CAMAC equipment long before the Internet was a gleam in Al Gore's eye. (My lame attempt at humor, sorry.)
It's not rocket science, but you probably learn a lot by going to the Network > Switch page on LuCi and posting a screenshot, we can tell you how your device is wired up by that.
This is a good beginner project. Log in to the router on wifi so that if you misconfigure the Ethernet you would still be able to connect.
If you do have a separate eth port and thus a software bridge, connect whatever uses the least bandwidth to that port.
@dkwalton hi , please go through the link once
there is nothing wrong if you dont need any WAN concept and making a custum project having only LAN
"Ask and you shall receive." Thank you arjuniet.
YES! That is seriously good advice. Logging n via WiFi so as to maintain a connection. See, I should have thought of that if I knew what I were doing. Bits and pieces make a whole.
A post was split to a new topic: How to assign the wan port to work as a lan port on the r8000
This topic was automatically closed 10 days after the last reply. New replies are no longer allowed.
If you already have an existing DD-WRT router, it can be used to increase the range of the Vilfo network by setting it as an access point.
By placing a DD-WRT router after Vilfo, your DD-WRT router can be used to extend the wireless network of Vilfo.
In order to turn your existing DD-WRT router into an access point, two steps need to be taken.
Step 1: Turning your DD-WRT into an access point
Log in to your DD-WRT router
Navigate to Setup ➝ Basic setup
Under WAN Connection Type ➝ Connection Type , select Disabled
Under Network setup , check the following options: Local IP Address: Verify that the IP address entered here is in the same subnet that Vilfo use. Write down the IP-address shown here (By default, 192.168.1.1 ) Subnet Mask: Check that the subnet mask is the same one Vilfo use. By default Vilfo uses 255.255.0.0 , if the subnet mask differs from the one shown in Vilfo, enter the new one to match the one Vilfo use
Under Network Setup , enable the option Assign WAN Port to Switch
Under Network Address Server Settings (DHCP) , enter the following settings. DHCP Type: DHCP Server DHCP Server: Disabled Use DNSMasq for DHCP : Disabled Use DNSMasq for DNS: Disabled
Click Apply settings
Connect a network cable between the LAN port on Vilfo to the WAN port on your DD-WRT router
Step 2: Changing the DD-WRT router IP in Vilfo
In order to be able to access the DD-WRT user interface after the change has been made, you may need to change the IP address of the DD-WRT router to match that of Vilfo.
Log in to admin.vilfo.com
Go to Menu ➝ Devices
Locate your DD-WRT router in the list of devices
Click on your DD-WRT router in the list of devices
Click Edit on the new screen
Under Device IP address , enter the IP address of your DD-WRT router that you wrote down previously.
Click Save changes
To make future changes in DD-WRT you will need to do so using the IP address assigned to your DD-WRT router by Vilfo.
Note! If you choose to use your DD-WRT router as an access point, you may want to disable the Wireless network in Vilfo.

Dd wrt default wan port assignment
Dd wrt default wan port assignment.
Finally, I set up outbound NAT so this interface could access the Internet. I pressume ping true wireless works because ath0 is assigned to br0 as default while eth0 is indirectly assigned to br0 true vlan1 and does’nt work. Turn off DHCP before you continue! If we go no further, we have a programmable switch that can describe as many as 5 vlans, between which we can do sophisticated routing and filtering.
LAN Uplink Through LAN Port To complete the link between the two routers, connect a LAN port on the central router, to a LAN port on Linksys router to be used as your WAP. DD-WRT Virtual Wifi Network Assign security to this, if you require. Enable this if you want to use WAN port as a switch port Optional NTP Client: You will need to disconnect from the DD-WRT repeater, then reconnect.
But that ignores the wireless part of it , which adds some extra complexity. You can connect the WAP to the main router via LAN-to-WAN so long as you have assigned the WAN port to switch see step 3.
Because its so important, it is worth repeating: All movement or non-movement of packets between the virtual lans is determined by routing logic behind those devices which is normal linux routing , filtering , etc. A few more tips.. Vlan0, [Vlan1] is the one on which all of the numbered RJ45 sockets on the back belong to. I set up a static IP address on the GuestNet interface and also set up DHCP to issue IP addresses. Check our our full selection of DD-WRT pre-installed routers. Be sure to make a backup as mentioned in the following section of the tutorial.
In DD-WRT’s default case, this is vlan0, [vlan1]. In this tutorial, we will create a subnet for each VLAN. Down the Basic Setup page, the option WAN Port appears. What this area does is allow you to create multiple automatic assignment addresses for IP addresses in a network.

I use rt-ac68u as repeater mode. I want to make use the WAN port for LAN traffic. DD-WRT has an option to 'assign WAN port to switch'. Is there an equivalent nvram , robocfg or ip command in merlin to make it happen? Thanks

nvram set vlan not applicable! because on each restart vlan sets by init script. only robocfg in /jffs/init-start must help
- Dec 25, 2014
AndreyPopov, Do you have example of robocfg to set this up? I tried this and it did not work robocfg switch disable vlan 1 "0 1 2 3 4 5t" switch enable Thanks
New around here.

I have an answer, not for any uploaded Merlin firmware, but rather for the built-in Asus firmware. I was originally in "Wireless Router" mode, as per factory default. I tried disabling WAN altogether, and also NAT. That just made the WAN port entirely unresponsive. Then I changed the major 'Operating mode' to "Access Point", and the WAN tab of the menu disappeared. From then on, the WAN port of the device behaves as if it's parallel with the 8 LAN ports.

How to use LAN1 port as second WAN port? (dir-615)
I have STB, internet connection with PPPoE and router D-link DIR-615 with dd-wrt. I want to STB ip will be assign from ISP directly. Or set up iptv something different.
P.S. Router is D-link DIR-615 rev. E4
- 2 It's really hard to figure out what problem you're trying to solve. What is the end result you are trying to achieve? – David Schwartz Apr 3, 2012 at 10:03
- I do not quite understand how to configure vlan for iptv (STB) on the dd-wrt. Forums described this problem with the dlink-320 (also on the dd-wrt). The problem was solved by creating a second wan port for STB with the command switch , but I have this command is not available.

- The problem is that iptv does not work on TV. Usually a wire from the provider, the wire from the STB and the wire from the wi-fi router connected to an unmanaged switch, which broadcasts multicast packets to all ports. I wanted to do it with only one router. – Goozler Apr 3, 2012 at 10:57
- are you running the latest version of dd-wrt? if so, what version is it? – Jeremy W Apr 4, 2012 at 3:35
From the DD-WRT web page, go to Setup and then VLANs . Choose the port the LAN 1 port (1) and put it in the same VLAN the WAN (W) port is in. (Probably by unchecking VLAN 1 and checking VLAN 2.)
- I don't have tab VLANs . In the Setup -> Networking there are VLAN tagging, bridging, port setup, etc., but they are all bound to the interfaces (eth0, eth1, ath1, etc) I tried to do it through an SSH client commands nvram set vlan0ports = ... vlan1ports , but have not figured out where each port. The maximum I could do is give the WAN port in the off state. – Goozler Apr 3, 2012 at 11:18
