I upgraded my Aironet 1850 to the latest Mobility Express version, 8.3.112.0. The upgrade was performed from console, using tftp.
After the upgrade process, wireless networks are still working. SSH login and configuration also works as before.
However, the web interface only gives me a day0 config page, telling me "Cisco Aironet 1850 Series Mobility Express Welcome! Please start by creating an admin account."
Would like to get the web interface back, please advise.
Edit: Going to /screens/dashboard.html manually (instead of /screens/day0-config.html) I can log in and see the admin page. Strangely, it only shows one WLAN, CiscoAirProvision-profile-1234. I daren't reboot nor continue with the wizard for fear that my configuration might be lost...
