I'm looking for a little feedback on the compatibility/safety in running Thibor 15c on my trusty WRT54G hardware v. 2.0 router because I see it's based on the GS code instead of the G code. While I haven't had any problems after just upgrading to it, I'm just concerned about running the GS code on my G router. So my question is this: While I cleared the NVRAM both before and after, and I haven't encountered any problems, are there any problems with running a different hardware codebase on it? Either now or down the road when flashing to other firmware? I only ask because Linksys' site always has warned to use the firmware for that exact model, and they do have different firmware code for the G and GS router models. If anyone could shed some light on this for me, I'd really appreciate it. FYI, I previously used Hyperwrt 1.4 (Avenger) for the past several years and only needed to upgrade to a newer version when my new work BlackBerry wouldn't connect via WPA-PSK. T-Mobile has virtually no coverage at my home (I prefer Verizon), so I needed to connect it over Wi-Fi to use its UMA mode -- incredibly awesome! Upgrading to the latest stock Linksys 4.21.1 firmware solved my problem (chose stock firmware for a "clean test"). So I knew the problem was the old firmware. I then flashed to Thibor 15c to get back all the other enhancements, including the transmit power control I needed. Very cool.
