internet and network will work for about a minute, then neither will work until I manually repair the connection, when they will again work fine for a minute before stopping again. I have updated the firmware in the Linksys 54G v 3 router, and have also loaded the latest drivers for the laptop wireless card. other laptops on the same network do not have this problem. also, I have set the beacon interval to 50, frag threshold to 2306, and the rts threshold to 2304, but that hadnt worked either. I really appreciate any help you guys could offer.

Do you have any wired connections at the same time? Are they losing the connection too? Have you looked at the event viewer? Have you tried a static IP instead of DHCP? Where is the router in relation to the laptop?

sorry I didn't include this info in the original post. I have three other wireless and two wired computers on the network, none of the others have problems. the router is in the same room, about fifteen feet with clear line-of-sight. I have reset the computer and signed on to a friends network last night with no problems; I have been using the problematic network now for about ten minutes. If it freezes again then I'll reconfigure the router to use static and see if that helps. the problem might have gone away; gremlins. looking at the event viewer, I see six consecutive sets of error messages (both associated with the clock not being able to update) each seperated by one information message telling me that the computer successfully connected to the network. there are no messages telling me that the thing disconnected for one reason or another, just messages telling me it reconnected or that w32time can not update the clock. once again, thanks, and It might have somehow fixed itself...

okay the problem is still there. I tried disabling dhcp but I dont know how to connect to a non-DHCP network via wifi >doh< so i reenabled it... The problem starts after the computer being on for about fifteen to thirty minutes. could it be a computer overheating issue? maybe i just need to RMA the thing.

You don't have to disable DHCP on the router to give the problem machine a static IP address. Just give the NIC a static IP that's not in the DHCP range. Then test it. Of course, make sure that the IP is on the same subnet.
