how do i regain internet access?

[Bacalao]

Restart your Computer.

If that doesn't work, disconnect and Reconnect your Router.

If you still cannot connect to the internet, connect your PC to your Router using an Ethernet cable and flush your DNS:

Press the Windows key + R
In the run box type cmd and click OK
When the command prompt opens type the following. ENTER after each new line.
ipconfig /flushdns
ipconfig /release
ipconfig /renew
exit

If that doesn't work, take your PC to your local computer store.
I know OfficeMax is now offering free PC checkups.
