Preserving User Sessions on OpenWrt Access Points After Power Outages

Hello everyone,

I have 30 Access Points (APs) running OpenWrt, with CoovaChilli installed for use with RADIUSdesk for authentication. The network is connected via ZeroTier, which was set up through OpenWISP.

I'm facing a significant issue with preserving user sessions. When there is a power outage and the APs reboot, users are required to re-authenticate, which causes considerable inconvenience.

Is there an effective way to preserve sessions so that re-authentication is not required after a power outage? Any advice or guidance would be greatly appreciated!

Thanks in advance for your help.

UPS whatever keeps track of the sessions.

Radiusdesk is not OpenWRT, you have to ask them.

Sounds like high frequency of power outages/oscillations. It should be possible then to somewhat circumvent the issue using MAC-auth, too. Depending upon algo of randomizing MAC on clients, to be disabled, may be. Dunno, whether RADIUSdesk has this option. Plain, simple RADIUS+coova can do it, though.

A Google search for "coova-chilli preserve sessions on reboot" yields this among its results: Keep sessions active on reboot, which seems what you're looking for.
