ePMP Release 3.5.2 is now available

Yes we are having the same issue, we upgraded our AP from 3.5.1 to 3.5.2 and had the same issue. Will try to downgrade our AP to 3.4.1 as what they have suggested, leaving our SMs to 3.5.1. Hope it will resolve the issue.

OK, what am I missing? I upgraded a Force 190 to 3.5.2 and I still don't have access to DFS. I've tried three different browsers so I'm not looking at a cache issue.


Hi all,

3.5.5 Beta Firmware with FCC DFS support for Force 190 has been offcially posted.

https://support.cambiumnetworks.com/files/epmp/beta

Thank you.

I have noticed some issues with the Ethernet interface every one of my subscriber modules which are running 3.5.1 or 3.5.2 seem to flap on the LAN interface only common thread is that they almost all have ASUS routers attached.

The second is the throughput  is not what should be expected on the downlink  again I am only seeing this issue with ASUS consumer routers.

However speed issue doesn't exist  when testing using the ePMP the degradation in the speed is only seen when testing across the link to our local testing server or an internet speed test.

If we remove the router on the customer end the and plug directly into the ePMP than the speed issue does not exist.

Has anyone else noticed this?

Any idea on time frame for 3.5.5 so we have an official release of DFS for Force 190's? I hate to run beta in a production environment.  Anyone out there running 3.5.5 beta on Force 190's? Any issues?

we've got 30 or so 190s on 3.5.5 beta, everything running fine on them.

After upgrading from 3.3 to 3.5.2, clients are accidentaly disconnected. It happened in one church. The APs are located on the sides. 3 out of 5 ap we downgraded  to 3.3 and stopped the problem. It does not matter if it is with or without gps.

What version are the subscribers?

There seems to be some stuff missing from SNMP in 3.5.2... specifically, the pppoe username (it was on iso.3.6.1.4.1.17713.21.3.4.3.10.0 with 3.5.1 and older).

There could be other stuff too, but I that's all I've noticed so far.


This still doesn't appear to have been fixed in the 3.5.5 beta... any chance that we could get that fixed? it's preventing me from upgrading...

Chris any APs on 3.5.5? We are wanting to push new firmware as I've got clients on 3.4.1, and APs on 3.5.2... 

I had the exact same problem.The device would show offline in cnmaestro and LibreNMS... but I was able to ping it (I also had no GUI access) and I could see the SMs connected to the AP and still passing traffic through (I asked one of the "offiline" customers).

I had to call the customer with the "offline" device to reboot the radio (unplug and plug the poe bar plug), and when they did that and reconnected back, it was showing online in cnmaestro, LibreNMS and I had GUI access. This problem was spreading like a virus, it first happened to a couple of v3.5.2 devices and a couple of days later, it happened to 30+ devices. I had to preemptively reboot the rest of the radios I still had access to before anything happens to them.
