Well, firstly I'll say hello as this is my first visit to the forums.

Hello....

Now to my question: I have a W960 and a WLAN setup and connected. Does anyone know how I setup the Internet (Web Browser) to use the WLAN as an access route for web browsing and emails?

I did visit SE/Support but they seem to base all browsing help on using the mobile network, which I don't need to nor wish to use.

Thanks.

Scan for Wireless Access Points within your phone's range... then select your chosen point.
If your access point is security enabled, type in that code when the phone asks you, then.... bob's your uncle.

Put WLAN under your preferred connection. So next time, it will first try connecting using that option.
