Nokia N95 wireless connection problem

[azzy]

Hi

I have a nokia n95 and i am trying to setup the phone to work with my wireless router at home, the phone can find my router when it does a WLAN scanning, I have also typed in the security key as well. The problem is when i click on the web icon or the "0" button to access the internet i get a error message saying:

1: Web: Unable to connect
2: No gateway

Please help on this matter. Thanks
