Hi ID245,
- Since when are you facing this issue?
- Did you make any changes to the comptuer before this issue started?
I would first suggest you to run Network troubleshooter troubleshooter in Windows 7 and check if it finds any issues and if it is able to fix it.

Also you may try to release and renew the IP address and check if it helps.
To do this, click on start and in the start search box type cmd. Right click on CMD in the list and click on run as administrator. In the command prompt type ipconfig /release and press enter. Again type the command ipconfig /renew and press enter. Check if it displays the default gateway and post back the result.
Hope this helps. Let us know the results.
Thanks and Regards,
