Is MR 26.6.1 stable release safe to upgrade ?

[Net7]

I am going to upgrade production AP to MR 26.6.1 stable release. Are there any known bugs that I should know about?

This sounds similar to something we've seen on MR16s & MR18s. It has some correlation with channel changes. Take a look at the RF tab on the AP. You'll likely see a normal traffic pattern followed by an AutoRF/DFS channel change followed by a flatline during which no connections will be made. There's definitely some sort of problem handling channel changes gracefully.

I haven't noticed that particular circumstance.

Around the timestamps I noticed when no more clients were associating to the AP on 5 GHz channels no DFS/channel chg events happened.

The only channel changes I did notice were on the 2.4 GHz band but not at the time of the last association and disconnect.

One of the AP's showed that when the last client on 5 GHz connected, it was deauth'd after a few minutes and that client reconnected on 2.4GHz on the same AP. So the bandsteering wasn't enforcing it either.

I'm following closely!

We see these gaps also (mainly reported because video streaming is popular at the moment) but Wifi coverage is very flexible at this customer, so no business affected ..

Will love to hear what engineering has to say (and how they will discover what's wrong) ..

I only had some issues with 2,4 clients like wireless printers and Apple Watch which ask me about the password few times. But after few days ago now its working fine. Maybe beacause i have many networks around my location, so its interferences in 2,4 GHz. On 5 GHz i didn't notice any issues.
