Since 2 days acces to this router is impossible on all devices. Password is the same for many years and was not changed.

Everytime an attempt is made to connect to this router the same message appears "wrong password" and it gives you the possibilty to fill in the password. When using the one that was set up it does not work.

Attemps to connect to the router settings through connecting it directly with my pc fail because no ethernet cable plug in available on my computer. Any ideas someone?
