Hello,
Shure, i used the right credentials for Login after Firmware reset. I also cleared the Browser Cache, like described.
I updated to the 07.01.04 Version before.
When i do a downgrade to 02.06.01, it is possible to login with admin/admin01, bur in the userinterface the wlan secion is missing and there is no wlan provided by the router. The three signal strength Led are keeping blinking. After installing the next versions of firmware above, 02.07.XX, there is no login possible. After reboot, the login screen appears and after filling it with admin/admin01, nothing more happens, but a rotating wheel. The three signal strength LED are keeping blinking meanwhile.
thanks for helping!
