just yesterday I started having extremely slow wireless speeds on my 2 week old WRT54G. it was fine before, but now I can't get over 10-14K/s on either local file transferring or on the local isp speedtest site. if I plug in my old wireless router, it works as it should, which leads me to believe it's not a wireless card or OS issue. (smc2435w wireless card) I've tried linksys official, linksys beta 4.0.07 or whatever and talisman, along with many resets, factory defaults, power cycles, etc. I contacted linksys support but they only advised changing a few wireless values (fragmentation and rts thresholds, as well as beacon interval) which made no difference. my wired desktop works fine, as does my wireless laptop if I plug an ethernet cable into and use it wired. network setup: cable (moto surfboard 5100) - WRT54G v3 - PC's and RT31P2 (vonage adapter). the laptop is no more than a few feet away, and both XP and netstumbler show a full signal. as I said, it's worked fine before, no idea what has changed.
