So i have been reading about custom firmwares for WRT54G routers lately. So i flashed DD-WRT into my WRT54GL. Saw that it had an overclocking option. Went from 200MHz to 250MHz but was unstable after a while. I ended up taking it apart and adding heatsinks to the ram and cpu and can run 250 stable. Your probably wondering why i did this. Really i did it just because i OC about everything i get my hands on that will do it. I have noticed a bit better performance with it OCed when you are really cranking on the network hard though.
