On my wireless network, consisting of two computers using an 802.11g Wireless USB Adapter and a laptop using its own Wifi card, from time to time I get frequent disconnects. It is rather more so infrequent because I can go on for long periods of time without a disconnect. I do not disconnect from the network, all that happens is (say Im in WoW, all actions stop responding and I know I have disconnected or lagging, and eventually I disconnect) so its my net that goes off. But when I restart my USB by taking it out then putting it back again as soon as it gets the network the net is fine again.
What I consider a "DC" is I lag or am not connected to internet from 30 seconds - 2 minutes, so much so that I have to relogin things like WoW or MSN. A force reconnect by restarting USB will usually get it back up and running. I disconnect or lag periodically when someone strarts up the computer/laptop, and it seems the laptop always gives some grief just in general >.< I think due to the fact that it runs off a wifi card.
I disabled WZC and now just connect via my USB Adapter conifugration software, still same results..
