Hi, I'm hoping someone can help me with this problem because I'm baffled and Linksys tech support is no help. I am running a Linksys Wireless B router (BEFW11s4 v 4.0) A Win box, XP Pro SP2, with a Wireless G card in it (WMP54G) and an iMac G5 with an airport Extreme card. All the latest firmware and drivers. OK, so. Both systems connect and work properly on wireless. Except I'm getting consistent yet random dropped connections from the PC (only wireless, ethernet cable is perfect). Yet it still says I have an EXCELLENT connection. I'll be going along browsing, playing WoW, or whatever, and in the system tray it will say "you are now connected to your (my network name) signal strength excellent" this is after it is already connected. This is the death knell as nothing will work after that. The solution is to view my wireless networks, disconnect, cilck reconnect, and BAM, working again like a charm. meanwhile, across the room the iMac has never lost connection and continues to run perfectly. The only issue the mac has is that 30 delay picking up the DNS after coming back from standby (but this is a known issue). So I've tried no security on the router, WEP (can't even pick up the thing) and WPA. They all do the same thing. I've tried all 11 channels and continue to have the problem. I haven't been able to adjust uPNP or the MTU yet, but I'm not sure I need to. The Mac working leads me to think it's an XP problem? Any input on this would be great because I just got this PC and it's driving me nuts having to dis/reconnect every 15-45 minutes. Thanks!
