Is MR 26.6.1 stable release safe to upgrade ?

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

Nothing that isn't on the release notes, we have been using it on more than 100 APs from MR32 to MR52 since it was released.

Thanks, I was just worried as previous stable release had problems.

Indeed, 25.14 was somewhat flaky!

Running the 26 train for a longer time without any issues. 26.6.1 is looking especially good.

Contrary to the reports of others:

 

26.6.1 still has an MR32 bug in it that prevents us from upgrading. It's completely unstable/unusable for us.

@randhall Which particular bug are you suffering from?

We weren't given a number but were told that it's a known issue.

 

The network is unusable when connected to an MR32. A continuous ping of the local gateway from a device associated to an affected AP shows a pattern of: no responses and high 20 second response times that get shorter and then stop. Rinse. Repeat.

@randhall  That's worrying.  I was all set to upgrade our estate this coming week, starting with a small group of AP's, but will hold off until I hear the outcome of your problem.  I'll do some testing in our lab setup on a MR32 here to see if I can replicate the issue.

Please keep us updated

 

Thanks

Excellent idea with the lab ..
I always do/recommend this in larger environment (pre-prod setup).

 

I don't have the MR32, so I did not get any indications of instability ..

 

Worrying indeed, could You post your responses from the Support case, when things turn brigther ?

 

In any case: Good luck tracking down the issue ..

 

With highest regards

@randhall 

 

Is this the only device connected to the AP? Is the device connecting via 2.4 or 5? There are quite a few of other factors that could be contributing to performance like this. Did this behavior start occurring on the 26.6.1 release?

 

Have you reached out to support on this as well?

We weren't given a bug number by support but they said it was a known issue. It extends a couple of revs back. Only on MR32s (150) out of our 750+ total.

We have a big issue with wireless printers. 

Other than that, it seems stable.

I'll try the ping test in one of ours, we don't appear to have that sort of issue and out of the 20 we have, two of them consistently have 15+ clients connected.  One of those is in an employee lounge where there is a huge transient population and the other has about 7 continuosly connected static iPads that run an app used to monitor activity.  If it was experiencing that sort of drop out for TCP traffic we'd definitely know!

When I upgraded to it, my nest cameras started dropping on/off the wifi. Few times a day. After 4 days of this I reverted back to the latest 25.13 and nest cams have been solid. Tried going back to 26.6.1 again and they dropped off/on again. Went back to 25.13 - solid nest cams. ¯\_(ツ)_/¯

@yepper  Hi, what model AP's are you running that these cams are connected to ?

Thanks
