1. The SIM is in use for 3 years on Android phone (Moto G 5G, Samsung M23) as USB/Ethernet Tethering to Mesh Router

2. Current Location also tried same phones and no issues , NX200 was swapped for missing band and CA on 5G

3. DNS is same for 5G and 4G+,  device doesn't suffer "Exception" conditions on LTE-Plus

 

 

 Thanks @Marvin_S,

 

I  shared multiple logs and waiting for feedback.

 

I reverted to old firmware "Firmware Version: 1.1.0 3.0.0 v60a2.0 Build 240519 Rel.754n"  and could see different behavior with same 10 seconds delays.

Restart of CPE SIM registration to 5G NR take 4 seconds, during normal operation LTE-PLUS to 5G NR takes 10 seconds on every switchover.

 

 

Changed Firmware Version: 1.2.0 3.0.0 v60a2.0 Build 240613 Rel.62450n and also 1.3.0 3.0.0 v60a2.0 Build 240627 Rel.48750n, the errors are back

  @myag 

 

same problem here, have you already found a solution? which provider do you have? use o2 telefonica.

  @Marc3012 

 

Still no. I am still tracing and sharing information with support.  

 

If you are getting same exception error, I suggest to open support ticket. 

 

 

I think I found the problem, I connected the router to a power strip with my Nas. I then plugged the router into the wall socket individually. I haven't had any problems with the internet for 2 days now, but I'll keep an eye on it until Sunday and then report back.

Support fixed 1 conditions for disconnections for Band = Auto mode.

 

 

 

Update  3 weeks testing:

Forcing Band to N77 multiple problems pop up.

* Modem resets connection with 8 seconds disturbances recovers new IP from ISP

* Modem hangs (frequent) on routing / webconsole / tether / Internet for 16-17 minutes and recovers retaining old IP

* telnet/webconsole/tether services gives software disconnection (frequent) error but routing/internet works for 16-17 minutes and recovers

* network services disconnects all connected devices for 16-17 minutes and services returns back 

 

 

 

 

Update:

 

 

Band set to = N77

Band set to = Auto (NX200 active band during error N77)

 

Yellow highlights = no internet 16 minutes No Network (lan/wifi) & recovers 

Green highlights =  no internet 8 second modem resets

Red fonts = CPE reboot on own.
