Note: this has been cross posted to Microsoft.Public.Windows as well: http://groups.google.com/group/microsoft.p...15cb573d723820e I put Vista Ultimate 64bit on a new PC about a week ago, with a wireless network card. and have been having a problem that manifested itself in online gaming (Counterstrike Source and Half-Life DM specifically) but has also cropped up in Remote Desktop. The symptoms are that when I am playing, every minute or so I get a burst of lag, which clears up in about 2-3 seconds. Obviously this is incredibly annoying and makes it unusable. I've done all sorts of things, including trying several different drivers, and two different cards - all with the same results. After some major googling, I think I have found the culprit, but can find no way to fix it: the WLAN Autoconfig service is pinging every 60 seconds to try to find wireless networks in my vicinity. I confirmed this by doing a ping -t to my router, and sure enough every 60 seconds on the nose I see a <1ms ping turn into a 800-1300ms ping. Unfortunately, I don't believe there is any network configuration software for my cards (dlink and netgear) so if I shut off the service, I lose the network. I tried to shut off just the autoconfig portion in the command line (using netsh wlan) and then setting up the network manually with my SSID, but it still won't connect without the autoconfig on. I've poked about in the registry as well, and found several keys for this service relating to the "Scan Interval" but changes to these settings don't seem to make any difference, and I can't find any documentation on them. How do I either get around this, or set up a much higher interval so that its not happening every minute? This is a desktop PC, so I don't really need to be looking for other networks... and it seems ridiculous that I can't shut that portion off... Thanks
