tridium asks: "I recently moved into a new place where the landlord left a Linksys WRT54G v2 router for us to use. The three laptops in the house running XP connected to it fine, but my desktop, running Vista RC1 build 5600, had to be hardwired. The Internet worked fine for a bit, but I noticed some websites weren't loading up (Google, Gmail, and several others), and IM clients weren't working. Vista's self-diagnosis said it couldn't communicate with the DNS server, so I researched and it seems the new TCP stack in Vista is wreaking havoc with my router. I upgraded the firmware from Linksys, tried manually setting IP settings, modified the registry to disable TCP window stacking, but nothing helped. Linksys support was also useless in fixing the problem. I'm at a loss and any help, short of downgrading to XP, would be greatly appreciated." Other people have experienced problems getting Vista to work with off-the-shelf routers. A thread from September identifies the new window scaling feature as a potential culprit, while another article says that Vista and SPI-enabled routers don't play well together. Whether the problem is related is unknown, but another thread offers some troubleshooting tips for anyone else who may be experiencing this problem. Has anyone figured out how to disable (or at least work around) some of the more troubling aspects of Vista's new TCP 'features'?
