Unfortunately after the latest firmware update, the router has become very unstable on the 2.4 GHz network
it fails and no longer works properly.
Unfortunately, a hard reset of the router does not help either.

You also cannot downgrade to an older version as that is not possible with this firmware.

Will there be a solution for this problem, this has been going on since 2020-08-10 and still no solution to date, also the helpdesk is waiting for a firmware update or beta firmware to solve this problem as soon as possible.

But unfortunately they also complain that it takes so long and that the complaints keep coming in about this router.
