Note that repair installs leave much of the registry alone - this is why you
don't have to reinstall apps and why your account is still there.
If the problem is in the registry, a repair install isn't likely to fix it.
Sometimes subtle registry problems can be so hard to track down and so
obscure that it's faster to wipe the system and start over. Some problems
aren't worth identifying, and unique problems can be nearly impossible to
find.

Have you tried resetting tcp/ip?
http://support.microsoft.com/kb/299357
and check lspfix, and
And also uninstall your network adapter drivers, and shut down. Restart
and allow them to be reinstalled. Reinstall the motheboard chipset
drivers.
Try setting yourself a fixed IP address between your PC and your router.
Give it one just outside of its DHCP range to avoid conflicts.
Also, google things like "can ping cannot browse". That leads to posts
like this:

"I have RESOLVED it !!
I think Winsockfix should be able to do the work, but I had no means of
getting the software to my machine. So in my usual searches got to the
following page.
http://www.cexx.org/winsock.htm
Going by the instructions, here is what I did:
1) opened regedit
2) clicked to HKEYLOCALMACHINE\System\CurrentControlSet\Services
3) renamed WinSock2 folder to OldWinsock2.
4) closed regedit and restarted windows.
5) deleted all network drivers and restarted machine. This reinstalled my
network drivers.
6) restarted machine, and reconfigured my TCP/IP.
7) restarted machine, opened IE and back to the browsing.
For a person not confident of using the above, winsockfix should be able to
help.
Cheers !"

Consder where to draw the line for the value of your time, between trying to
diagnose and just redoing the system from a re-built partition with no
possibility of rootkits etc.
