ePMP Software Release 5.10.3 is now available

IMPORTANT NOTICE
The updated cybersecurity requirements of the European Union Radio Equipment Directive (RED 2014/53/EU) will become mandatory on August 1, 2025. To comply with these changes, firmware version 5.10.2 and later no longer include the default WPA2 key in the configuration. If the default key was previously in use, SMs may fail to reconnect to the AP after the upgrade. We recommend referring to the Cambium Community for the recommended migration steps.

Problems corrected

Tracking ID Products Description
AXG-12470 All Fix for an issue where the USB GPS receiver may not function on FCC versions of the F4625 and F4616.

Just FYI, I updated one of our ePMP 3000 sectors that have only 3 subs connected, and at first one of the F300-16’s only had the ability to use a limited amount of frequencies.

20 Mhz was missing 5845-5885
40 Mhz was missing over 2/3’s of the frequencies.

Luckily it was still connected to AP with current frequency of 5200Mhz, so no truck roll necessary. I tried reverting firmware but got an error with something along the lines of “wrong SKU”. I then rebooted the SM and all frequencies came back up and all good for now.

Just figured it’s still worth mentioning here.

Yikes, that’s scary… I think I’ll hold off updating until the next big release.

Yea, I usually wait until the last maintenance release (or at least a .1) of the next major firmware before I typically update.

Everything else (100+) is on 5.10.1 and has been running really well. Ill just keep them there for now.

We had this happen on a F300c backhaul which is on 5.10.1 a couple days ago. There was a large storm and a wide area power outage and this particular backhaul went down, we initially assumed it was power, but when logging into the Master side, we could see it only had a handful of channels available, NOT including the one it was configured for - so the Master was in hold off and wasn’t transmitting. I didn’t screenshot or download a support file, I just rebooted the AP, and when it came back up, the full list of all the regular channels were listed as available, and it started broadcasting.

However the slave side did not reconnect - So I configured the AP side to one of the handful of channels which it was previously limited to before the record, save that, and the Slave immediately linked up. I then logged into the slave side and it also just had that same smattering of channels available. I was then able to reboot it, it booted back up with its normal compliment of channels, And I was able to reconfigure the link to its original channel.

Stupidly, I didn’t save a support file from either one of them - We had storm related issues over a large area of our network, so I was in ‘fix ASAP’ mode on everything.

This link’s been working fine since, but it was a strange thing.

Has anybody else experienced the above issue with frequencies missing on this firmware?

I’ve seen one a few videos they speak of a base being loaded with 40 subs, Are you saying its performance will be massively affected if say we do 80 or 100? One would assume mu-mimu negates this affect.

This has the e3K mu-mimo correct?

Hi Guys, we have 43 subs running flexible with mu mimo was rebooting 5 times a day turned mu mimo off and its stable. Just a heads up. I will be testing fixed frame to see how that goes as i know they have mentioned that it wasn’t stable on flexible. Just needed better latency.

Hi @russ007 ,

by any chance do you have a techsupport file right after the reboot? Could you PM it?

Unfortunately I don’t, I can re enable it and wait for the first reboot but clients were getting a but frustrated. I had assumed the reboots were erasing the logs.

In any case, drop me, please, a techsupport from AP you have right now. I will check configuration/ It may also give some hint
