AIMesh config

Disable this...

set up the other device as an AP

Seriously... your problem will likely go away after that...

As much as I believe AI Mesh is buggy, for this specific issue it is not at fault. At no point of problems I see any evidence of laptops/iPhone getting disconnected in the router event log. And all the systems are stationary.

UPDATE #1: Finally got Rogers to update the FW on the router - 7.1.1.35, but they refused to disable OFDMA saying that it is getting better. So far I did not have many calls yet (they got pushed out to tomorrow), so tomorrow I will know for sure if the new FW resolved the issues or not

UPDATE#2: @Datalink, any comments on this event log:
