Some firmware revisions (e.g. qca6174 with fw73) don't deliver beacons to host reliably. This causes random disconnects even in perfect conditions. This is most visible with multi-channel operation. All available firmware revisions seem to support beacon miss offloading so there shouldn't be any problems.
