We are using around 200 routers, based on mikrotik devices, usually RB433xx and R52Hn . Two years ago we started to use MIMO technologies (N standards) . Sometimes some of the MIMO links hangs. It is still connected (link in wireless table windows si marked by "R" as connected), usually in Tx I can see some datas are transmitting, but Rx is "0 bps" - no datas received.
When I disable and enable the card on one side of the link (not metter on which side of the link), the link is connected again and everything works correctly.
It happends on more our links, I don't thing that it is hardware problem, because change of the hardware don't solve the problem. I don't thing that is is routeros version problem, because it happends 2 years already and we upgrading routeros often and new version of routeros does'n help.
In my opinion, there is some bug in routeros.
Actually I solve that by software script, which every 2 minutes checks by ping if link is working. When the second side of the link is unreachable, it disable/enable the wireless card.
Any idea how to solve that, not by software resetator?
Re: R52Hn - sometimes Wireless hangs
What do you see in logs when this happen ? Add wireless logging topic before. [ /system logging add topics=wireless prefix=debug ]
Re: R52Hn - sometimes Wireless hangs
I checked log from yesterday evening on the router, where wireless card hangs. There I can see nothing interesting about that.
It hangs wlan4 around 22:35. I see, there no message about that.
There you can see, I logged there on 22:43 (as user "koci"), disable and enable the wireless card wlan4, it was connected again.
Here is completly log from the router from that time:
