have just come up with a strange situation. My DELL desk top this afternoon lost internet connection. ever since i am getting no or low connectivity and no access to net. Ive even rigged up to run wireless but again no good. My laptop IS working wirelessly through same sky router so it isnt the service provider.
Any ideas why desktop isnt working

The "Limited or No Connectivity" indication means that the network adapter has failed to get its IP address from the router. Windows defaults to allocating an address in the 169.254.x.x range, which won't let you access the router or internet and gives "Limited or No Connectivity".

If you're connecting to the router by ethernet cable, try repairing the TCP/IP stack and Winsock.

Open a Command Prompt window ("Start > Run", type CMD and click OK).

To repair the TCP/IP stack, at the prompt, type...

netsh int ip reset resetlog.txt

...and press Enter

(note the spaces in the command line). The original prompt will reappear, exit the Command Prompt window and reboot the PC.

To reset Winsock entries, at the prompt, type...

netsh winsock reset catalog

...and press Enter

Exit the Command Prompt window and reboot the PC. (If running both repairs, reboot only after running the second command.)

I very occasionally get a sluggish connection with my (wired) modem router - disconnecting the mains adapter lead for a second or so and allowing the router to reinitialise normally cures it.

However, some weeks ago, when it happened this didn't work; it eventually transpired, after a range of checks, that the ADSL filter/splitter had developed a fault.

Replacing it immediately cured the problem.
