we have a problem with our Wifii. we have two laptops, one my partner does her work on and wifii works fine with hers and my laptop I have to have an ethernet cable in order to get internet to work on mine. Also to get Netflix on our smart tv we have to have an ethernet cable to get that as the Wiftt does not work. Our Echo dot does not work either. Now we have a Kindle Fire which my partner got for Chiritmas and we can't connet that to Wifii. What in the world is going on with this?
