i assume you meant firmware. i use a linksys wap54g (access point only) that is usually trouble free. i have installed hacked firmware by mustdie that i found on this forum
. he also has created ones for the wrt54g as well. the revised firmware allows you to adjust the antenna's transmit power from 1 to 84 mW (default is 22). the wap54g has run pretty much trouble free since i've had it (a year and a half). i had the wrt54g, but gave it to a friend when i needed a router with vpn capability. she has not reported any problems with it to me. in the time i had it, it worked well, but it needed to have the latest linksys firmware installed to work properly.
