E410 after update firmware from 3.11.4.1-r3 to latest 4.1-r3 radio 2.4 go down every day

Only 2.4 go down, 5GHz still working.
Before update firmware i have no problem on 3.11 with same configuration.
How to fix it?

hi,

please share ap techdump. if ap managed from cnMaestro, go to device tools section and down load ap techdump and share to us cie001@cambiumnetworks.com

Emailed techdump.
I use my AP stand alone without cnMaestro. I made a tech dump from the admin area, but the information is saved in the logs only after a reboot.

May be “Enable Auto RF” option turn off 2.4 GHz? but it’s is off

received techdump and will update.

Repited :frowning:

I catched the moment of 2.4 wifi down

This moment in wifid.log

In scmd.log

In infrad.log

Hi

I have same problem with your E410 at 4.1 r3 . Waiting for new firmware release. So sad.

Is the issue happening regularly ? if so, how the recovery happening?

Were the clients able to reconnect back after disconnect ?
Are you able see the SSID in the client WLAN list when client got disconnected ? 

Please download and share the tech support when the issue is live. Please share on this email id anv100@cambiumnetworks.com.

My E410 offline all time when upgrade to 4.1-r3. I send the tech support file to anv100@cambiumnetworks.com. Please check it.
Thanks so much.

Hi Hongtran,
From the techsupport logs, it looks like the connectivity between the AP and the default gateway is lost. This is the reason the AP went offline. Please find the logs from the tech support for the same .
