Linksys Alternative Router Firmware
If your router is not compatible or you do not follow the proper flash instructions for your router, you make brick your router and have to buy a new one unless there are ways to unbrick it. I am no way responsible for anything that happens to your router.
This is honestly one of the best firmware’s to use, and anyone that wants to simply make their router better should use this. The installation process is extremely easy.
At one point for a while I was using DD-WRT after the original Tomato firmware stopped being updated for the latest routers (anything with N+) for the last few years, until 2012 (and I know slightly longer) were more compatible with the newer routers today without many issues.
In the past, I use to own versions of the Linksys WRT54G and you will find that Tomato is the best custom firmware to put on this router and other compatible ones. You can read all about it at the main website: http://polarcloud.com/tomato.
As posted at the Tomato site, here are alternatives for you to use if you do not want to use Tomato.
