With my old router I don't have problem with my i780 detecting and connecting to the router. But when I upgraded to Belkin, my i780 can no longer detect the Wi-Fi. I tried to turn off the n protocol of Belkin and use only b/g and my i780 is able to detect the signal and connect. When I switch on again the Belkin n protocol, my i780 jus failed to detect the signal, it just simply display unavailable from the Wi-Fi settings.
Looks like the i780 is confused in detecting the Wi-Fi signal with an n protocol enabled. All my other Wi-Fi devices works just fine.
Anyone encountered this problem before? How to fix this?
