I have a WRT54G with 2 PCs connecting with a WUSB54G USB wireless ethernet dongle thingy. PC #1 works flawlessly. PC #2 will be working along and suddenly the dongle loses the Link light, the IP address goes to 0.0.0.0, the Linksys utility (and the Microsoft wireless utility) both say we're still connected to the router (though we cant ping it or do anything else). The only way I can get back ethernet is to reboot, or uninstall the drivers and reinstall them. I can make this happen consistantly if I try to do heavy copying from another device on the same network segment (my tivo). I've swapped cables, network cards between the two machines. I've updated the drivers to the latest (220.127.116.11 dated 4/13/05). Has anyone seen this behavior before or have any troubleshooting suggestions? I've now configured the problem machine to use a static IP, but I'm guess this wont help. I'm about to go test by copying some files down off my Tivo. Thanks for any ideas. ... actually it dropped while I was typing this but then allowed me to reconnect manually this time. That's better than a reboot I guess.
