This seems to have come back on me.
Router OS is 6.44.3 on hEX and cAP AC
devices on the 2.4 radio are disconnecting from the wifi. Log into the router and check the logs and see...
(MAC of Devices) disconnect 4-way handshake timeout
Devices on 5Gig radio do not show this error.
Last time I reported this, support would send me one email per month... I removed the Tik Wireless and Went to Ruckus and stopped getting angry calls.
MIKROTIK SUPPORT...
I just submitted a support file via email. Please take a look at it and figure out what is wrong.
