On my 10" tablet I use my neighbors which my dad helps them keep on in exchange.The only problem is that last night it was working great and I wake up to it not connecting on my iPhone(4),nor my tablet.The is correct on both devices and displayed on the tablet it will say Obtaining IP address,then authenticate and take forever.After a minute or two it displays "Avoided poor internet connection." Even though the signal strength is Good
And the speed is 65Mbps.What can I do to fix this?
