The new S205 is unable to find my home's WLAN router however am able to detect the neighbouring WLAN routers. The other devices such as mobiles and pads are able to connect to my WLAN.
Do ensure that the WLAN security setting is set to WPA/WPA2 rather than using WEP security. If the router is set to WEP, login to the WLAN router and configure it to WPA/WPA2 security, save the router settings and reboot the router. Once the WLAN connection is stable, use the S205 and search for your WLAN router again.
