So I moved into a new house, got a new router and new internet provider. My computer is connected to the router through the cable while all the phones and laptops are through wifi. Everything worked for a week and no nothing connects to wifi. Only my computer works with the cable. All the phones and laptops and xbox one, all of these cannot connect. I can see it in wifi but it is very very week and when I try to connect it connects and then disappears and connects again, but just does not work anywhere. Please help asap.
