Does anyone know if running the WRT54G @ 251mW for extended periods of time will cause any harm down the road? I ask because I'm a little worried of how much I'm pushing the unit, but I love how far it goes. BTW I'm also using two 9dBi FMI (CompUSA generic brand) antennas. Right now I'm running the unit @ 230mW and it seems to be doing fine, but I don't want to hurt the unit cause I want to get at least 1 year out of it before thinking of upgrading. Also, should I be worried about heat build-up, or put a larger heatsink on the chip, or is fan a good idea or anything like that?
