Does this release fix the issue where the AP->Monitor->Wireless table would randomly show SMs with 0% DL Capacity that I thought someone else reported was there in the latest betas?

No, this doesn’t appear to have been fixed… and yes, this was reported in early 5.10 betas.

4

I can still select flexible mode, Should I change it to manual to us mu-mimo etc.

5

Is it the same during/after WLT? On my setup it gets blue as soon as I run some traffic. It is momentary indication. If SM is idle for a long time it can drift to zeros.

6

The fix is coming in 5.10.1 soon.

Thank you.

Apparently, MU-MIMO in flexible mode is still not optimized in 5.10. This will be addressed in upcoming 5.10.1 release.

8

I updated an epmp3000 and Asymmetric Uplink Bandwidth Support does not appear

9

This feature can only be enabled on e4k AP’s.

PPPoE seems to be broken in 5.10.0 (on AX, I haven’t confirmed whether or not AC is affected yet). If the PPPoE session drops, it doesn’t seem to ever re-connect. I confirmed 5.10.0-RC36 also does this, but it looks like RC35 might not be affected (most of the 5.10.0 final and RC36 clients on the AP weren’t working, but there were a couple on RC35 that were still working, but there were a couple of others working as well, so that could be a coincidence).

For added context, I had this happen on a tower that had some backhaul issues because of storm damage, so it probably was getting significant packet loss, but PPPoE did reconnect on the clients as soon as I rebooted them, so it’s possible that it’s just giving up after too many connection attempts fail, or something like that.

Asymmetric Uplink Bandwidth Support
The Asymmetric Uplink Bandwidth feature is introduced for ePMP 4xxx/Force 4xxx and ePMP 3xxx/Force 3xx devices

12

Unfortunately, the release notes don’t provide full clarity. The asymmetric feature can only be enabled on e4k AP’s. e3k SM’s connecting to an e4k AP using backwards compatibility mode that have asymmetric feature enabled will ONLY connect at the full channel width… NOT at the reduced uplink channel width.

See this post for guidance on asymmetric features and use cases:
