This release includes general stability improvements for the ePMP 3000 radio. There are no new features.

Hello. So just to clarify - this 4.5.6 release notes are basically “General stability improvements” for the AP, and that’s that - correct?

So only if we’re running 4.5.5 on a 3000MuMimo, then this should go on there and will add ‘stability improvements’, correct?

Other than that, no changes for F300 or 3000L, 2000, or anything else.


4.5.6 is the recommended version to run on all AC platforms.
There were major stability improvements introduced for ePMP3000 and ePMP3000L.
If you are not experiencing any issues on 4.5.5 then not to much sense to move to 4.5.6 since there are no new features introduced.

Thank you.

OK, I was asking because cnMaestro says that 4.5.5 is the recommended version.

OK, thanks. I was asking because the release notes don’t mention the 3000L - only the 3000.

Yea, Ive noticed that CnMaestro is Cambium’s “long term release” train.

Hi Fedor, for when an upgrade to F300-13L? we are having a lot of SM needed to rebooted any time…

Hi Alessio,

The latest FW released for F300-13L is 4.6-RC29 Beta.
If you experiencing any issues with F300-13L please reach me at fedor.trutsko(at)cambiumnetworks(dot)com.

Thank you.

Thank you Fedor, we are testing and send a feedback later.

A post was split to a new topic: Elevate frequency range

This won’t be a particularly useful reports, but here goes.

In one location, we have an ePMP1000 AP, with a Force 300-25 and a Force 300-16… and when we upgraded to 4.5.6, the F300-16 came back like this. I de-registered her, and she re-regged with the same IP, I rebooted the AP, and it came back the same. I still CAN do a throughput test to her, and she get’s her full 60 Mbit plan according to the built-in AP Wireless link test.

Anyway - NO - I don’t have support files to send in anywhere, we of course had to focus on getting the client reconnected. I downgraded the AP back to 4.5.5 and we called her and got her to power cycle, and that worked.

I’ll try to upgrade this again after the long weekend, and I’ll post back here. This may have simply been “one of those things”, and nothing to worry about…

Force300-25 PTP link (in TDD mode) at 1.2 KM with signals in the 50’s with SNR in the 40’s and DS9/DS9 modulations. This link has been reported several times before.

Last time was when the 4.5.5 release came out… this link had an uptime of several weeks on 4.5.4-RC16, and when we upgraded it to 4.5.5 it went down twice in the next few hours, so we rolled back to 4.5.4-RC16.

That was 35 days ago, and so with 35 days of uptime on 4.5.4-RC16, we upgrade to 4.5.6

It has now stopped passing data again tree times over the ethernet of the AP side as before, so we are rolling back to 4.5.4-RC16 until we can replace this link.

If you have epmp2000 running 3.5.5 is there an intermediate step to upgrade or can you go from 3.5.5 to say 4.5.5 or 4.5.6?

@NetOpsCom, You can do directly to 4.5.6 or 4.5.6 from 3.5.5.

Does this update benefit ptp 550 in any way?

No it doesn’t.
4.6 Beta includes some PTP550 improvements.

Thank you.

Couldnt find any docs on what those improvements are in the 4.6 Beta.

Most of the time Cambium puts release notes alongside the firmware. You can find release notes for this beta HERE.

Dont see any notes for 4.6 beta but thank you!

There right there, in the link I sent you.

when I get to that page , it only has join beta forum… which I have in the past so not sure why its doing this…
