Starting from the obvious, check that the cables are installed correctly.
You have to have a cable that brings the internet to your place.
Connect that cable into the router's jack labeled Connection to Modem.
Then get another network cable and plug it into any other jack form the back of your wireless router, and the other end into your laptop, just to make sure you are getting connected.
Once you are sure you can surf the net, unplug the wire from your laptop, and you should be able to surf wirelessly.

And if you still can't connect, let me know to perform additional steps.

Many thanks.

Wireless routers can operate at the same exact frequency as cordless phones. Try switching to another frequency in the router configuration.

If you are connected straight from the modem, your router will not have internet access, only if your modem is connected to the router you will be able to go online wireless. connect your modem to the router nad router to the desktop, so that you can access both wired and wireless connection

If you're connected to the router with excellent stregth then the problem most likly lies in the routers connection to the internet. Check your DSL, Cable modem and make sure the connection to the "Internet" port on your router is good. Try switching out the Ethernet cable if nessciary.
