Hi - I seem to be having a similar problem that others have with windows 7 -have gone through the usual issues and none have solved it. I have a Dell Optiplex 745 -just did a clean install of Home Premium. Started dropping the internet connection. ipconfig release and renew solves the problem, as does disabling and re-enabling the nework adapter. I disabled power saving options on the network adapter and gave the machine a static ip. This did not solve the problem. I have verizon DSL and a westell router. I can usually log in to the router @ 192.168.1.1, but no internet access. (router reports good connection and another machines on network can access the internet) Weird thing is - the router says my machine's ip is 0.168.x.x instead of 1.168.x.x I don't know if this is related to the issue at all. This is getting very frustrating. Any help is appreciated.
