I am not able to connect to Internet because it throws 691 error with false username or password.
I use fritzbox 7530 since last 1.5 years and never had this issue.
Although, in last few days I have transferred the contract ownership to the new tenant. So today, initially fritzbox had continuously red light on Info button but internet was working. After that once I restarted and since there is no Internet and error is 691 code.
How can I resolve this issue? What should be the next step?
Thank you!
