I've tried fooling with the channels, the encryption type, etc. What happens is my apps or Web pages fail to load. If I turn off wifi, they work just fine.
I have multiple tablets working just fine at home and hardwired computers that never lose Internet so it should not be an issue with the gateway.
Any other ideas for fixing this? I had a Galaxy S4 which had issues with AES encryption but I tried TKIP and same problem here.
