Hi Pete. When you run the network diagnostics what errors, if any, does it report?
Try these steps to reset the networking components:
Click the start button and in the search area type: device manager
and open the search result at the top.
In Device Manager, expand the entry for Network Adapters
Right-click on your wireless adapter and uninstall. Don't remove driver software.
Once done, close Device Manager.
