Here's a few things you can try

Click on your internet access icon in your taskbar. In the bottom of the window that opens, click on "open network and sharing center". On the left hand side of the window click on "manage wireless networks". Right click all your listed networks and remove them.

Once those steps are completed, turn off any device that connects to your router. Unplug your router from the power supply and wait for a minute or so. Plug the router back into the power supply and wait until all your activity lights are lit and flashing. Now boot up your computer and set up a new wireless network.

These might or might not solve your problem, but with any wireless network connectivity issues you may encounter this is a good place to start.
