I have a Sony Vaio that has a clean installation of Windows 7 Ultimate and all Ethernet and Wireless drivers. I can connect flawlessly and rock-solid at home, but I cannot connect at work, no matter what I try. I've tried direct Ethernet connections without a firewall, checked my IP, but I get only a connection to the router itself and no internet access. It always shows the same: Connected. No Internet access. I had the network admin there in the office check the IP assigned to my Vaio with another 2 laptops (HP) and they both picked it up when assigned this IP, but mine won't. I tried assigning it three different open IP addresses, all of which failed. Connected. No access. No access either wired or wirelessly. I'm really stumped here. Can anyone offer any suggestions? The diagnosis tools in Win 7 didn't help one bit. Surprise.
