Overall my wireless stability has been improved for me, been running 2.2h since it was released. With 2.2f, I did experience a symptom that was unrelated to the main problem in this thread: Entire Network Will Go Down When Desktop Is Connected, as I was seeing repeated dropped connections for some of my IoT devices. To make that more stable, I had to set my Air-Time efficiency to 1000kbps. With 2.2h, I noticed that I was able to revert Air-Time efficiency back to defaults and those IoT devices no longer disconnect. So, I’m liking 2.2h so far! It seems to have fixed the issue that I was seeing in 2.2f.
Thank you Alta team!
