That actually seems pretty unlikely, since a bazillion other people use 
the same drivers...  Or at least it is a quirk of your setup that 
triggers the issue.  Do you have wireless phones in the same frequency 
range nearby?  I do, and see disconnects that I think are related in my 
d-link router logs but haven't seen any problems with connections being 
re-established from anything including my son's macbook.  Have you used 
wireless in any other locations, and if so, do you always see the same 
problem?

That doesn't make much sense but you are probably trying to reuse a 
socket that has received a reset - browsers open several sockets 
simultaneously and the others might not have been busy during the 
network disconnect.

Do you mean disable the wireless NIC and re-enable (which sort-of makes 
sense) or doing something to the router?  If you really have to restart 
the router, that's probably the source of the problem.

Hardware is all pretty much the same - it either works or it doesn't.
