Why does my laptop's wireless network fail to work after resuming from standby, requiring a reboot?

The laptop in question is a Dell Vostro 1400 laptop, integrated Dell 802.11g adapter, Windows XP SP2. The adapter works fine and can detect and connect to the networks with no issue, normally. But it freaks out sometimes.
I'll give you a typical scenario:
I open the laptop on my lunch break at work and connect to my office WiFi network (802.11g, WPA, static IP). Works fine, stays connected through lunch. Shut the lid and take the laptop home after work.
Get home, open the laptop. It resumes from standby and I set the IP to DHCP. It sees my home network (802.11g, WPA, DHCP) and tries to connect to it, but fails. I've tried repairing/disable/re-enabling manually, hard-disabling the adapter from the laptop's front switch and re-enabling, and stopping the WZC service (which refuses to restart). When I do a repair, it takes f-o-r-e-v-e-r to disable/enable the adapter, and stalls at "Connecting" for several minutes, before it finally bails and errors out. No matter what, it won't reconnect until I reboot.
When I reboot it works fine (though the network services seem to take a long time to start). Even if I reboot with the IP still set to my work's static IP, I can change it to DHCP and it connects fine. (Point being that it requires a reboot for the interface to even work, and doesn't appear to be related to static IP vs DHCP)
Even stranger: If I reboot, it works fine until I shut the lid and go to standby again. If I resume, there's a 50/50 chance of it working again. It might work, it might not. It might work for 30 mins and then flake out, and nothing works but a reboot. Last night, for instance, I put the laptop in standby at home, then brought it to work today. I started it from standby during lunch and changed my IP and it connected fine. It died an hour later and wouldn't come back until I rebooted. Eh!??
I think it's a "bigger" network adapter issue. I also have a bluetooth module in the laptop and it works fine all the time, but if the WiFi drops then the Bluetooth doesn't work either. That's not even the same adapter! Is there a service that's flipping out or something?
Please throw any suggestions my way. It's not specifically related to one or even two wifi networks; it happens on whatever network I'm connecting too. It seems like it has to be an adapter issue!
Note that this system was originally Vista but I replaced it with a fresh XP install. Dell does have up-to-date XP drivers though, which I'm running.
