I have similar problems with linksys... everytime i give presentions outside on Wifi and return to the office the adapter cannot be found or the wireless software vanishes off the face of my laptop. I have XP, use the linksys wirelsess G Router, Wireless G Notebook Adapter 2.4 ghz as well as the VoIP (vonage with three phones hooked up) Yesterday everything worked fine. today when I booted up the adapter cannot be located by Windows, it doesnt light up and again all the software is GONE!!!! :evil: Why is this happening? Is it windows? Dell Wireless Utility fighting with windows fighting with Linksys? I love it when it works but now after spending hours with Linksys, the love is fading! HELP!!!
