When I try to go online by WLAN I get a message "Unable to connect WLAN. WLAN network not found". I have working WLAN network from Netgear wareless router and my laptop is working perfect. I have open network (not encripted). Do I need to be a sign for any extra service from my TMobile (USA) provider to get WLAN connection (USA)? I did not sign to t-zone or internet access from TMobile.

Thanks,
Mikhail

If you don't have the latest firmware for both, router and phone, consider update option starting from Netgear router.

the WiFi is seperate to your mobile provider.

As said, try updating your router, and adjusting settings. I have always been surprised at the number of WiFii routers i can see with the E90, its quite impressive. Standing in a busy street i can pick up 6+ networks , and have never had much issue connecting to any unsecure ones...

Id go so far as saying its better at connecting to WiFi than PC counterparts...
