Windows XP SP2 killed my network

Or 'Compters often make people quite angry part 2'

Last week, after installing the USB wireless network on my computer, I thought everything was working ok. Unfortunately not so. During the week, my network connection kept dying. Using the 'repair connection' option would cause the computer to hang, requiring a reach for the power switch to reset it.

I tried the usual things: uninstall/reinstall, download new drivers from the manufacturers website. Nothing seemed to work. A quick check of various websites suggested that it's likely to be a problem with XP service pack 2 and USB wireless network devices. I tried some of the solutions mentioned: let windows manage the connection, let the software which came with the adaptor manage the connection, check the USB power saving settings. Nothing helped.

As I was getting ready to return it to the shop to exchange it for a 'proper' internal card (I only chose the USB option because it was the same price and should've been quicker to install), Emma suggested we swapped adaptors from her machine to mine. Her computer is running SP1, mine came with SP2 pre-installed. We swapped the cards, reinstalled the drivers, and (touch wood) everthing seems to be working ok.

As an aside, on friday our wireless router kept losing connection, requiring regular resets. It would connect to the Internet but neither of us could connect to the router. On saturday, we upgraded the firmware and re-initialised it. So far it seems to be working ok again. I don't know whether it's just a coincidence or whether SP2 had somehow managed to affect other devices on the network.

I thought the idea of one computer having such an effect on the network was a little fanciful, but I have since observed something similar. I was using FTP to transfer data between two machines (sitting at computer A, using a drag-and-drop interface to copy files from computer B to computer C). Part way through a transfer, all the computers connected to the router would simultaneously disconnect. The first time it happened, I thought it was just a random event. The second time, it was a bit annoying. The third time, it was obvious what was causing it (but not how it was doing it).
