Cannot see SSIDs except for mobile hotspots, why? I have no idea why, but I cannot see any of the SSIDs, except for mobile hotspots from phones or laptops. I am from Belgium and am in the USA now, if that matters. Someone told me, it's because I can only see 802.11n networks and they are probably broadcasting 802.11 b/g, not n. Am i really not able to connect? Or can I change my settings somewhere to find those networks. This is really inconvenient :/

Edit: Could it be related to the channel it is sending out? Are they sending over different channels in the USA and Europe?
It seems they were broadcasting in 5GHz only, which my phone cannot receive...
