I have an AT&T Gateway Modem/Router and wifi works properly with my laptop just fine but I can not connect either of my 2 Samung Cell phone or Samsung Galaxy tablet to the wifi. I have never had this problem before yesterday and my devices are always connected to WIFI. I can see the network and I try to connect and it just gives me the message trying to connect over and over with no success. I have powered down the router several times to see if that would work but no change. I think it is weird that all devices that I can not connect are samsung so I wonder if that has anything to do with it. Does anyone have any suggestions?
