My Sony Ericsson Walkman phone is not able to detect the Wi-Fi network which my laptop can access, though it shows other access points except my Wi-Fi access point. Is there any setting to change for this? I have WPA/WPA2 network. What can I do to fix the problem of Wi-Fi in my Sony Ericsson Walkman phone? I would really appreciate your useful information regarding this. I hope to hear at the earliest from you guys out there. Thanks.
