The assurance thing is pretty mega if properly implemented.Have worked on other platforms with this ML/AI stuff mixed in and was great to get to RCA a lot faster.

Can IP Connections logging be used in conjunction with DNS logging ?

3

After the upgrade I cannot access the web interface via IPv4 address, I get ERR_CONNECTION_REFUSED.
Access via IPv6 address works fine. SSH also works.

Hi Drazen and welcome to the Cambium Community. Can you please create a Cambium Support ticket and request that Cambium Support CC me (Gary Hansen) on the ticket?

Can provide more details about your requirement?

Yeah, this version is a disaster. After upgrading I can’t access my wifi. I used a cable and tried to access the login page but no luck there.

Managed to ssh and reboot to the backup firmware.

But seriously, I expect more than this for an enterprise product. The kernel is old, Qualcomm drivers are old. Come on!

What devices model?
I had no problem with xv2-21X and xv3-8 (until now…)

XE3-4 is my model. Pretty basic setup.

XV2-2. I opened a ticket, they are working on solving the problem.

I have a work around for you.
If you go to the cnMaestro AP Group>Management then where the port number is at you change it to say 8443 or 4443 you should be able to access the web GUI again. I had my MGMT port set to 4443 before the upgrade and then changed it after the upgrade to 443 and I am now able to access the WEB GUI again.

This probably means it must restart the internal web server to start to answer again

12

That would be my guess as well

I am reporting a problem with 6.6. With the upload of this software version, the music sharing device “https://www.bluesound.com/” stopped working. They buffer the first 2 tracks after that it kind of clogs. After reverting to 6.5 everything works fine.

In addition, the selected version Indoor region Poland, and 6.6. goes on channels 100 and up
