This remains stable with the B-BOX 2.4GHz connection, and is the settings on the SFT 1200 as above
But special LUCI setting to "legacy" was removed, it is N for the 2.4GHz interface.
This SFT setting is/was ...
"Allow Switching to Other Saved Networks" is/was DISABLED
"Force 20MHz Bandwidth for 2.4G" is/was ON
The uplink SSID is offered by just 1 AP only.
Connection tracking is set to OFF, and is set to Failover (what cannot happen, no check, and no ethernet or USB connection.)
Country was set to BE before in Advanced setting (LUCI)
The wireless interface are set before the "repeater" was started. Set to 40 MHz for 5GHz band, and 20 MHz for the 2.4 GHz band. (As all my AP's around are set.)
Time to move on?
Switched 50 minutes ago to the hAP ax2 as uplink AP, instead of the B-BOX.
Same connections ... CuDY TR1200 and GL.inet SFT1200 to the 2.4GHz (wifi2) interface.
This is not the WLAN1 of Mikrotik, as AX hardware only works with the Qualcom wifi drivers. [package qcom_wifi]
My laptop connection is to the 5GHz interface on the hAP ax2 (managing the travel routers is done via an open port 80 on their WLAN interface)
Ookla Speedtest shows relative low speeds, like 10 Mbps down, for both travel routers.
But no instability or disconnects for more than one hour now.
These qcom_wifi drivers don't give me the detailed information as the legacy MT WLAN drivers.
But result seems to be identical to the B-BOX experiment.
One hour is not enough, I need days of confirmation with this intermittent disconnect problem.
Need more test setups also.
Only then I will try the Mikrotik WLAN environment with 10 AP's @home , and 35 AP's @holiday resort, all with the same SSID name. (The typical hotel setup !)
Problem here is, that when it works, it keeps working for other setups, and when it fails, it also fails in previous considered good setups. Some things are stored or cached. Can be seen as "cannot connect to network" happens even on the laptop, until deletion of the known network, and needs reentry of the credentials.
Lock BSSID is added for a reason, however SFT1200 is not in the supported list. ;-(
