experience • RB922UAGS-5HPacD
We bought 15 devices.
and after a few days it became as follows:
Sometimes stops working ethernet. Is seen in the system, but the data do not go through it. Disable /eneble not help. A reboot is required.
Sometimes longer be seen R11e-5HacD • 802.11ac / a / n. Everything is working normally, just not visible interface.
But most importantly, reouterboard reboot several times a day.
6.23 reboot, reboot + 6.27 kernel failure, reboot + 6.28 kernel failures, 6.30 shut down and not start up.
Exchange for a new one did not work, the same problem. Power jack 15V / 10A poe24V / 1A jack 24V / 2A
We return back 14 devices, we mounted back RB711 / RB 435G without any problem.
