I bought a Linksys E3000 Router. I have hooked it up and connected my PS3, laptop, iPad, 2 guest laptops on occasion with no issues. However, my fiancee's laptop will not connect to the internet. It connects to the network fine, just not to the Internet. I keep getting the same error "Cannot communicate with Primary DNS Server". I searched through this forum and found a few threads, but none of them solved my issues, so I am asking for help. She is running Windows Vista SP 2. I tried all three of the solutions suggested by Vista, but they all failed. I also did a hard reset of the laptop, router, and modem. Waited a little while with everything unplugged. Still cannot connect to the interent and get the same error message.
