For ANYONE with Wireless / Netflix / Youtube / Slowdown Issues
Don't buy an adapter!!!
My suggestion would be to go into your RGs control panel via 192.168.1.254 Get the Device Access Code/System Password from the side of the RG, it is NOT the same as the wireless network key. Then goto your wireless network configuration page. Find the wireless channel and make sure it's NOT on AUTO. If it is, lock it into a channel besides 1, 6, or 11. I usually use 9. I'd be willing to bet money it will at least make it better. It won't always fix it, but that auto channel feature is garbage and they should remove it from the gateways. I've helped countless customers with this issue as a Uverse Phone Tech. I've found that most people with iPads or other Apple devices will notice the issue the fastest. I don't know why but it seems to effect them worse. There is probably an 80% chance this will fix your wifi issues!
