I've seen quite a few networking issues pop up with Vista by now, and you are right, that does seem to fix a lot of them. I guess IPv6 isn't really used much if any yet and a lot of consumer gear must have conflicts with it. Its a nice idea that vista automatically put it in in preparation for the future... but we all know how extra complexity using protocols that aren't fully implemented goes. :/
On a side note, if removing IPv6 doesn't help Jugs446 then he could always try to assign a static IP to his wireless connection.
I don't have Vista in front of me ATM, so please bear with me the wording might not be exact, but to specify a static IP address you would need to: Get into the network connections, and right-click on the wireless network connection and choose properties. Find TCP/IP v 4, highlight it and click Properties , then move the dots from "obtain automatically" to specify, and type in, in Jug's case,:
Ip address: 192.168.1.120 (last octet should be a number between 2-254 and not in the range of numbers dynamically assigned by the router, Linksys routers usually give in the low hundreds so I would avoid those, but your router gave you 33. To be safe you could use 200 instead of 120, I was really just being arbitrary.)
subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1
and give yourself 192.168.1.1 as your primary DNS. (If that doesn't work you could try the DNS server of your actual Internet service provider, you would find that out by bypassing the router, plugging straight in, and doing an ipconfig from a command prompt.)
