Does the Antenna reboot ?
In other words, does it loose power ? or just the port flaps ?
The AP will then reboot (losing power).
AP that are connected via a 2m network cable (i.e. very close to the switch) will also lose power, AP down/up.
LAN (without POE) work without problems. So there must be something wrong with power supply (POE).
SwOS version ?
2.13 (best so far!)
I switched to SWOS, because since then there are a little less problems. But I think that I will soon return to ROS, because I have more functions. Temporarily I use SWOS with its own script on the Linux server, which checks for AP inactivity and then notifies me.
If the wifi is loaded during the day, it comes to these failures. My fear is that then more current/watt is needed via POE, so that CRS328 can not cope with it and then simply disconnects the connection to not overload the power supplies (or whatever).
I have already tried everything:
IGMP disabled on SWOS
RSTP disabled in SWOS
Multicast Enhancement: disabled in Ligowave/AP ("Multicast Enhancement" deactivated today and tomorrow we will know exactly if this is the cause.)
and much more.
Most services (like mDNS) I have disabled at Ligowave.
At another location we use Router Board RB1100x4 with ROS. There we also have Ligowave AP in use and not a single down/up. Everything runs stable. Also a CRS326 in connection kit Ligowave AP. Everything runs stable. All same firmware, same AP products etc.
Problems with Ligowave can actually be excluded. Or does anyone use Ligowave and have problems with it? I don't know anyone who has problems with it.
So the problems are only observed in connection with CRS328. We bought several of them and only because of POE, now we realize that prepares us big problems. I wonder why Mikrotik does not fix the problem? It would be very bad to find out that the problem is hardware related and therefore unsolvable. We have a Mikrotik dealer who no longer has CRS328 products. And I wonder if there is a reason that CRS328 were taken out of the assortment?
