Hey guys just purchased a galaxy and is pretty new to the android system. I've searched over the internet and even went back to the store to check the problem

My 3G is working fine, messaging and everything else. I've connected to my wireless network (DrayTek 120 full bridge to a ASUS RT-N16) and it connects and strong and quick connection however there is no data flow.

Nothing is loading and as if i'm not connected at all.

I took it back to the store and their wireless network connected fine and worked perfectly...

I've fiddled with all the 'never' wifi sleep mode and all that jazz but have no idea where to go from here

My previous iphone and laptop connects to the wireless network fine..

Thank you in advance
