I recently moved house and now my laptop can't connect to the WiFi. It was always a bit temperamental, but now when I go to access the WiFi, it shows the available networks but dark as if there's no WiFi bars. I'm connected to the WiFi on my phone and it's about 2 bars. I was looking at getting a WiFi extender but I tried to connect my laptop to my phone hot-spot and that didn't work either, though it showed all WiFi bars. The router is next door in my landlords room so it's not easily accessible. Please help!
