I wrote about the old Linksys WRT54GL before, here, the updated firmware were slow and had problems with the indicator LEDs, never lit up the Wifi indicator after upgrade.
I sat down and checked others blogs who had updated and what they had written about it and decided that I’d give it a try — I downloaded an image from the OpenWRT site matching my hardware model, opened up the administration UI and uploaded the image, done. In less than 5 minutes my old Linksys had a new life, with full control over everything, it took a few minutes to setup everything from scratch again but it was easy-peasy with the LuCi interface.
Also learned that the maximum radio output effect is 630mW .. 0.63 Watts .. a perfect candidate for the 8000mW signal amplifier I have eyes on. I could actually fit two 8000mW signal amplifiers on it, one on each antenna.
