I already did the factory reset via button on the side of the router. Now when I connect to the admin panel to input my admin password for the initial setup I get the error message:
It sound the error has to do when the environment is offline aka the router, and the page you are seeing is a offline cached version of it where the api calls fail.
Please ensure your connectivity is restored.
that you are on the same subnet as the router
maybe make sure to force dhcp by doing ipconfig /renew followed by ipconfig /all through cmd, if on a pc.
and try icognito mode in case of weird caching problems
double check if no vpn client is active on mobile or pc these can block access to the router.
If all above still doesn't bring up a solution, I want to know more information.
This is a known issue on the A1300 4.5.22 firmware version that occurs when the password contains special characters.
Please try setting a temporary simple password using only letters and numbers.
After successfully logging in, you can change it back to a strong password (with symbols) under SYSTEM → Security → Admin Password and use it normally.
This issue will be fixed in the next firmware release.
Beta 4.7.x version also fixed it.
