I have the following problem with the RB4011iGS+5HacQ2HnD device:
The router is running in station mode and connected to a NON-MikroTik AP via 5GHz. The MT router initiates every 10 minutes a background scan and the connection is lost briefly afterwards.
Hi, I had a similar problem with my connection in the hAP ac Lite dropping almost every hour, triggered by that background scan. (Testing hAP Lite, hAp ac Lite, hAp ac2, wAP ac, Omnitik ac, SXTsq ac for WDS, bridge and PtMP)
Yesterday I stopped the “searching for a better AP” on the hAp ac Lite, and the disconnects did not happen anymore.
On the hAP ac Lite, as ‘station bridge’ in one of the ‘virtual AP’, I entered “interface wireless set station-roaming=disabled” . Verified setting with “interface wireless print advanced”.
I hope my hAP ac Lite is a “sticky client” now for this PtMP setup.
Still it’s weird MT Devices in station mode lose connections during background scans. Latency spikes during BG scan are to be expected (that’s why gamers using WiFi disable BG scans in Windows to fight “ping spikes”), but the station to AP connection should not get lost.
Millions of Smartphones and PCs do WiFi background scans by default do search for better APs without losing connection. They are also smart enough to postpone BG scans while WMM prioritized VoIP/Video traffics is transported. And support 802.11k/v neighbor hood reports greatly reducig the need for BG scans.
For what it’s worth I just found an issue between an RB922 running 6.48.6 and wap R AC 6 running 6.49.6 in mesh config the mesh connection kept breaking every 2-3 minutes. I tracked this down to a script that was doing a background scan every 2-3 minutes.
From here it gets interesting.
This script has been running with a duration=13s for years on the RB922s without breaking the mesh, but as soon as the duration exceeds 10s (on the wap r ac) it causes the mesh connection to be dropped and reformed.
