hello i recently unsuccessfully tried to connect to a friend's wifi and now my 2 favourite wireless devices do not connect. I cannot test with a cable as I have only a phone and dongle hotspot, but other devices connect to them fine. I attach my IP config as I've seen previously someone on here has mentioned an empty 'default gateway'. I think I have that, but i have tried to set my ipv4 to automatic, i get message saying that i need a wifi adapter card. as you can tell, I do not understand much of this stuff. thanks for any help you can offer!
