wireless disconnects at school not at home

[Reel]

I have a laptop with a DLink DWL-G630 and a DLink Di-524 at home. My wireless will disconnect and reconnect briefly rarely (as is common with the Di-524). I am not concerned about my home connection. I have gone many hours without interruption so for my needs, it is essentially flawless.

However, at school, they have an 802.11b without WEP network set up. Once you associate with the access point, you have to authenticate yourself to access off campus sites. This usually works flawlessly but after some short period of time (seemingly random), ~10 minutes perhaps, the wireless will start to flake out. It doesn't actually show a disconnect or disassociation. It doesn't search for other APs. Nothing visible happens. I either restart or tell my wireless utility to rescan. It searches the channels, returns to that AP, and works again for a while. This repeats frequently.

Their troubleshooting doesn't address this problem so I have to assume it is not common for everyone. Does anyone have any suggestions?

1) Drivers have been upgraded?
2) Can you try some other hardware (different NIC)?

1) Drivers are the only version though I might be able to try a competitor's drivers that are the same chipset.
2) I probably could find someone eventually to borrow but I don't know anyone right now.

I was suggested to turn off the IEEE 802.1x setting in the network settings and try it again so I am going to try that today.

Thanks for your suggestions.

Try a different program to connect to the SSID, BOINGO is GOld for that. or netstubler

I tried it this morning. I was connected on campus for about 20 minutes without any problem. I am going to be back there in about an hour so I can try for another 45 minutes or so. I figure if it doesn't disconnect then the 802.1x was screwing it up.
