Does anyone know if older FAPs do not work anymore? Upgrade of FWF60E went fine but the FAP24D and FAP321C, both v6.0-build0044 did not connect, also after a reboot of the access points.
It is possible to create profiles for these access points but without getting a connection to the FWF60E.
Yes, this is a known behaviour documented in the FortiOS 7.0.0 Release note here. You may need to upgrade your FAP firmware so it can support the new strong crypto cipher requirement, or a work around is to disable strong crypto on the FortiGate as suggested abovee. You can see full details here.
