"The key or passphrase is incorrect"
My computer was connected to the wifi fine yesterday, but when I booted my computer this morning, the wifi was disconnected and when I try to reconnect it says the key or passphrase is incorrect. I have made sure I am using the correct password (same one being used on all of my other connected devices) and it still won't connect.
I have attempted to fix this in the following ways
-turned off and on computer
-unplug router for 30 seconds etc.
-hard reset of router
-made sure all drivers for wlan card are up to date (have also reinstalled the drivers)
-set up a new wifi connection with new username and password
-change the security settings to allow the device to connect
-contacted my isp and they could not fix it
-done a system restore of the computer to a previous date
I am stuck and can't think of what else I can try and what the problem would be.
Thanks
