The slow scrolling issue is fixed. THANK YOU!!!

When trying the "WiFi performance" tool, we get error "Error There is some issue in the network. Please try again after sometime." This happens regardless of TCP or UDP selcted as protocol.
Isn't the performance tool a speedtest between the AP and the cnMaestro controller, or have we missunderstood something?

What is the version running on the AP and please send the device model.

E400 running 3.3-r16

Would need a remote debugging to see what’s the issue.

Can you please run the below CLI command in your cnMaestro VMand see whats the output you see

UDP performance

wifiperf -s<IP_D> -d<IP_D> -X<seconds>

TCP performance

wifiperf_tcp -s<IP_D> -d<IP_D> -X<seconds>

For ex: wifiperf -s192.168.1.1 -d192.168.1.2 -X10

Regards,

Rupam

Does Wifiperf work over internet from AP to cnMaestro with only portforward 443 from internet to cnMaestro controller? If not, that's probably our problem.

wifi perf will work as long as AP and cnMaestro have the ip connectivity in both forward and reverse direction.

Wifi speedtest runs on port 18301 for both UDP/TCP, please check your network if its blocked.

We will update our help/user guide document.

cnMaestro cloud servers are also updated with 1.5.1 

How about scheduled firmware update  ?

Any ETA on next update and what it may include?

Timeline for PTP650 support?

Any plan for PTP820 support?

I know new versions are due to be released, but are there any release notes detailing the differences between the latest onpremise release r8 and the latest cloud release r18?  Did I miss a onpremise release?

Thanking you in advance

I am running cnMaestro version 1.4 and I need to update it to 1.5.  I have downloaded the update but the extension is .gz and Windows or the Oracle virtual machine does not recognize that format.  Is there a instruction sheet on how to upgrade because I don't see it?

Thanks ahead of time.

1.5.1 is a package release update and can be applied via the UI by logging into cnMaestro itself and uploading the .tar.gz file.

From the On-Premises User Guide:


Quote:
The package file can be installed on top of an OVA image and will only update the cnMaestro application.
Packages will be released more frequently, and they won’t require one to export/import existing data.
Packages can be installed by downloading them from Cambium and uploading them through the UI (at
Manage > Server > Operations).

 Hi,

If you're asking how you set a user's SM to rate limit them, then that depends on the type of equipment.  You could set up a template for the rate limit parameters and apply it to the selected SM(s) from cnMaestro, but exactly WHAT parameters you'd need to set will depend on whether the SM is PMP450 or ePMP.  (or WiFi)

I'd suggest starting a new thread in this cnMaestro section asking how to apply rate limiting via cnMaestro to the particular gear you have deployed.
