Is your router wireless?
Check your router configuration from your PC to make sure wireless is set up properly:
========================================================
The standard default IP addresses for routers are 192.168.0.1 or 192.168.1.1
This is dependant on the make and model of the router.
The default login is usually a variation of "admin".
It may be login admin, password admin
It may be login blank, password admin
It may be login admin, password blank.
If they don't work, check your router's manufacturer's site.
Of course both the IP address and admin passwords can be changed, so yours may not even be close to them. Worst case scenario would be to do a hard reset of the router, putting it back to it's factory default state... Meaning no wireless security, but it would revert back to factory default login as well.
Look up the manufacturer's website and you should be able to find the support documentation for your specific router.
You should change your router's default username and password.
