Some terminals do not work after the main/backup switch
Before the E2450P01 (not
included) version of WA6600 series AP, there was a problem that the terminal
did not work when the main and backup dual-link switchover occurred,
specifically, when the main and backup AC switchover occurred, some terminals
showed that the SSID remained connected, but the terminal could not ping the
gateway and the external network, and it was necessary to manually disconnect
the wifi switch and re-access the SSID to restore normal.
Upgrade the version to E2450P01 or above to solve the problem.
