I've just upgraded the firmware on a Draytek Vigor 2710n router, from v188.8.131.52 to v3.6.3. Now I am unable to login as admin or user with any username/password combination, including blanks. User login gives the helpful message 'User Mode is off now.'
I think that I need to revert to the original firmware version, but how do I go about doing that if I can't login?
The router is cable linked to two pc's and a printer, and seems to be working okay, but I need to add some laptop MAC addresses to allow them wifi access too.
