S2 not detecting network

[Thak]

I was hoping someone would be able to help,

My wife just came back from overseas and now her phone will not detect our wireless network, just says it's "out of range", yet my phone connects fine. I have checked all the settings which are ok, reset the phone and the router to no avail.

Does anyone have any ideas?

Many thanks.

Long press on the network name and choose "forget" then rescan.
