No i tried everything now but still not working! So i explain my router is down stairs, i am on the second floor! He sees my network but can't connect saying authentication error! When i go near the router about 3-4meters it connects to my network and i can access the net without problems! Now i am at my friends home and my galaxy s3 connects near the router but when i go in an other room it remains connected to the wifi but no internet connection an after a while he disconnects automatically!
I suppose if it where an hardware problem it wouldn't find the network at all or am i wrong with that?
