I do have 3 cap AC in my home wifi, recently updated to 7.13/7.14RC1 with new wifi-qcom-ac to have roaming working. Before this update I has no stability issues on the 7.x with the old wirelesss package, but ofc roaming experience was quite poor.
Now I do struggle with sporadic CAP ac freezes, randomly after some hours up to some days up to almost never on the less frequent used device.
As this was only very randomly happening, also for the Mikrotik support except giving hints to disable watchdog and create a supout after next crash is very hard to help, what I totally understand.
As of today - by accident - it looks like I found out how to easily crash my CAP AC with 100% reproducible rate. But I have no clue what happens and if my config is wrong (hope not, optimized it after hours of reading in the forum what to set up best for roaming
). I am familiar with IT in general, but "low level" debugging/sniffing on network traffic layer I never dealt with.I am using a Macbook Air M1, connected to 5Ghz with latest update.
I am connected to my companies VPN - if thats relevant
I am connecting via "Azure Data Studio" to a Azure MSSQL managed database and doing a SELECT query on a database which returns ~130k result rows. According to the results appearing, Azure is providing them not at once but one by one or in small bulks.
After around 60k results being displayed, the CAP AC i am currently connected to stops working (wifis disappear, device not reachable anymore via Web nor via winbox.
I have the feeling that the new wifi-qcom-ac has still some memory leaking issues or something else which in normal mode brings the AP based on usage to crash after some days but within this scenario alsmost instantly). Maybe lucky if this helps finding out the problems.
But as I said - I have no clue where to start and debug this. analyzing wifi traffic? And if yes how? Maybe if you have good hints where to start. I am willing to read manuals and work me into tools, but with no clue starting from the scratch I struggle a bit.
If you need my config, should be quite basic. On the device an DHCPv4 + capsman is running. Thats it. Do not wondr about the daily reboot - this was my "workaround" to mitigate the random reboots with small effort in daily work to almost zero
