In this How To article, we will discuss and instruct you in the process of using your old WiFi router (or a new one) to extend your wireless internet connection using the Linux based freeware DD-WRT. I will be using a Netgear WNR2000 v.3 for this How To. Why Extend your WiFi Range, There are many reasons you may want to extend your wireless connection range in your home or office.
The installation of a bunch of metal file cabinets or the rearranging of your office may have disrupted the wireless signal at your office. Or maybe you just like to have as strong of a signal as you can wherever you are in your home or office. Head on over to DD-WRT router database page and find if your router is supported. The most important instruction to follow in this process is to do research on the router you want to turn into a range extender.
The second most important instruction to follow in this process is to do research on the router you want to turn into a range extender. The third most important is.. However, a quick search on the WRT forums reveals that the flash file is too large to fit on the 4MB flash memory of the WNR-2000 v.3.
The person who discovered this then listed that version 18777 of the DD-WRT flash is the latest one that will work on the router, and supplied a link to that particular build. The above scenario is the perfect example as to the importance of doing research on your particular router before performing the installation of DD-WRT on it. First, I recommend that you have two computers available to you, one for flashing the router, the other to stay online to easily view instructions, troubleshooting, and keeping track of your process.
There are two versions of each original .img files, one will have the letters "NA" in it, the other "WW". NA denotes North American models, and WW denotes everywhere else in the world. Be sure to download the correct one. There is only one version of the .bin file, however.
Remember, the computer you use to flash your router with should be completely offline, with Wi-Fi disabled, connected with an ethernet cable only to the router you are converting to an extender, with firewalls and antivirus programs disabled. And don't forget to have read and understood all the instructions, from start to finish, for flashing your router. To begin, first reset the router to factory defaults.
There is a reset button on routers that often require a pin or other small object to push. Some routers require the the power to be on for the reset, some require it to be off. Consult the manual or manufacturers website to determine the correct way to reset your router to factory defaults.
Hold the button down for 30 seconds to reset the router. It is a good idea to recycle the power one more time before moving on to the next step. If your device has a power button, use it to turn off the router, if it does not, unplug the power cord. Wait a minute or two, then turn the router back on. Do not connect to the port labeled "internet" or similar on the router. That is the port that would be connected to a modem or another router, not a workstation or laptop.
It is usually by itself, or has a different color surrounding it, or some other indication that it is not one of the ports for normal workstation connection. You have assigned a static IP to the ethernet connection that follows the subnet scheme of your router (i.e., if your routers I.P. Log on to your router by opening a browser (DD-WRT recommends Internet Explorer, but many have used Firefox, Chrome and Safari without issue) and type the routers I.P. In my case, the I.P.
You should be greeted with a login dialogue box. Since you've reset the router, the device has reverted back to factory default user name and password. Consult your manual or the manufacturers website to determine the default username and password. For my router, the username was "admin" and the password was, simply, "password".
