Hello,
we made some fist tests with equipment with 802.11ac enabledin production sites in NV2 mode so we have AP withsome 5 clients.. Everything seems ok, but after some time there is some critical bug on Wireless to eth bridge. The client is hanged on AP all over, but datas are no passing bridge. The only solution is to restart device (but not always helps).
Then sometimes appear the log trigger System rebooted because of kernel failure. Used ROS is 6.19
+1 i confirm this behavior. SXT-sa + SXTac
Yes exactly
We have reboots and complete hangups. Sent several supouts to support.
Seems not to happen with RB922UAGS-5HPacD only SXT.
Insider,
how you have configured devices? as wds?
if yes, did you added to bridge wlan interfaces on AP side?
Does pings jumping if pinging to remote sites?
No, we dont use WDS mode any longer, We do use AP Bridge and Station bridge, and than adding interfaces to appropriate bridge

Thats interesting. what frequency mode you are using?
Could you change nv2 to nstreme? For me for now it helped.

We will try.. later today.. I got suppout rif, if MTik interested
Insider, please send those support output files to support@mikrotik.com
OK, sent.. Anyway. Nstreme wont work at all. System reboot as wel, but it helped to upgrade to ROS 6.20RC.. At least it came up after
Anything new??? It is really bad.. I have to restart SXT 3-4 times a day !
I use 2 SXT in PTP mode, as AP → Station bridge. on 6.19 was issue with kernel on high load, but on 6.20rc5 was fixed and work OK
it is 20MHZ cahhnel.
50Mbit full duplex TCP , or cca 100 mbit on one direction tcp
RC20 does not solved. May be it is a bit better but Kernel failure continues..
Hi,
I to have same/similar problem. Kernel failure - AP and Client SUPPORT.inf files attached
Using SXT G-5HPacD sectorial to one client using SXT G-5HPacD.
switched to 802.11n - no success
switched to 2omhz channels - this ACTUALLY CAUSED kernel failure
100 metres distance
checked radio noise - nice and clear
when I do BW test with 951s at each end to client falls over - this ACTUALLY CAUSED kernel failure.
see pics of AP and client
If 6.20 no fix then back to supplier and might have to pick AirMAX but would prefer not to. No choice.
Regards
Aidan

My all RB SXT ac ROS v6.20rc15 FW3.18.1 same problem - reboots during Freq. Usage, snooper 
the problem is not with you?
I can confirm that with 6.20rc15 device crashes during frequency usage scan.
+1 Same error with 6.20 final release.
ohh, i confirm this problem. i lose sxt when i scan,freq. usage and… .
help please, and fix problem.
Download latest drivers, it seems that guys from Mikrotik made good job.. I got RC11 of ROC 6.21 on friday, from that time no restarts, no bridge malfunction! Yeeha, so we are getting to spam network with thees devices,
They could have included the change in the changelog at least… No single word about it even you say its been fixed…
