It was all working fine yesterday and then I woke up and every time I tried to connect to the Wi-Fi on my phone, it would disconnect and tell me it was unable to connect. So I clicked forget network and tried to enter the password again and it keeps saying "Incorrect Password" when it's right. I got my MacBook out and tried to see if it was affected too. It also kept telling me that the password is incorrect but it's right and I've tried way too many times. I went downstairs and the computer is working with the Internet (not Apple, connected via Ethernet). I don't want to reset all network settings and lose other passwords. Also, when I click the information button at the side of a network, no information comes up. The IP address doesn't show and neither does the Router or DNS or Subnet Mask etc. What should I do?
