I have battling this problem for over a week. I switched from DSL to cable internet, and my Vista laptop is driving me crazy. Here are the details:
-I installed a Motorola DOCSIS 3.0 cable modem and connected it to a Netgear Wireless-N router.
-I hardwired my vista laptop to the wireless modem and ran the set up software.
-My other laptop with Windows XP connected wirelessly with no problem.
-When I tried to wirelessly connect my Vista laptop, however, it only allowed local access to the network and would not connect through to the internet.
-I removed all anti-virus/firewall software to rule that out-still no internet.
-I took the Vista laptop to another network that has a wireless-g router and it connected...hmm seems my network is the issue.
-I reconnected my DSL network and of course the Vista laptop connected.
-I ran ipconfig and the IPv4 address, subnet mask, and default gateway all match with the XP laptop (minus the last digit of the IP address of course).
-I've cycled power on the router, modem, and laptop several times.
Can anyone please help me before I throw this laptop out the window!?!
