Answer #1
Update drives.
Check to see if modem/router is working correctly and configured properly.
Answer #2
If DGray mans doesn’t work you could also try changing the channel. Log into the routers configuration, if you don’t know how it’s usually 192.168.1.1 or alternatively go to
Control Panel > Network Connections > Right click the one you are using go to Status > Support and the IP should be under default gateway.
Then go to configure wireless and change the channel.
