I recently changed the office network connection my Windows 7 computer from wireless access to wired with an internet cable to the router.
The Internet access is much, much faster, but for some reason this machine cannot see any others on the network. I can't print to network printers, or access any other machine on the network. On the network and sharing center, it's in the same workgroup as everybody else ("WORKGROUP"), but can see only itself in the network. If I click on "Connect to a Network", a little box opens down in the right corner, saying "Currently connected to: Network" and nothing further appears possible,
I checked the properties on the ethernet adaptor, and noticed that it says that I have IPv4 Internet connection, but IPv6 says "No network access" and I can't figure out whether or how to change that. Does that mean there's something wrong with the hardware?
Please help me on this, it's a mission-critical fault!
