Wifi password will not work on any of my devices

I have tried putting in the password for my wifi but it refuses to work it keeps saying that it is the wrong one and i have tried it on my computer and phone they say the same thing. I have tried using the Ethernet cable that has been working but i tried getting on 192.168.1.1 but it will not load. I have even tried using the command "ipconfig" code that it gave me and that website would not load either.

Are there any other alternatives ?:confused:
