I am having problem with my recently bought SONY XPERIA SL. I have CISCO WAP4410N router, and its SSID cannot be scanned or connected (manually) on my phone, while being on AUTO CHANNEL selection mode. Where as I am using the same network previously for my iPhone and even for different laptops.

While when I change the channel manually to no 10, I am able to access the network.

Anybody can resolve this issue for me?

An helpful app to resolve this might be Wifi Analyzer, it shows the available (and perhaps conflicting) wifi channels and their strength.

Is is quite possible that the channel it automatically chooses is too congested, or even not supported by your devices wifi card.

...or that it is in an "invalid range". Not all channels are "legal" in all places. So the router might chose an "invalid" channel, and your XPeria refuses to use it. – Izzy Dec 14 '12 at 21:16
