I just purchased a new desktop and installed Windows 7 Profesional.
I was able to connect to the internet via the router, after a lot of messing about and was able to register, activate and update my installation. However, today, when I booted the destop, it wouldn't connct to the internet, or see the othe computers or printer
in my home network. Whenever I try to connect, I receive the following :-error 651 and when I run Network Diagnostics, it returns with ""Local Area Connection" does'nt have a valid IP Configuration."
I have swapped the cables between computers and the problem stays with the new box. My laptop wirelessy connects via the router and sees the other devices ok.
Having checked on the intereet, I see that this is a common problem with Win 7 and have already tried the "raspppoe.sys " as suggested by "Shinmila H-Microsoft supprt on social.answers.microsoft.com. to no avail.
Please advise, or Email a hotfix.
Thanks for your attention in this matter.
