RG650E-EU - Modem Failed

[ffcorun]

Hi,

I’ve got a problem with a Mikrotik Chateau 5G R17 AX (S53UG+5HaxD2HaxD&RG650E-EU).

The main issue is that the modem is failed and the lte1 interface is unusable.

If I try to get the status of the device from the terminal I’ve got this error:

I’ve also enabled the debug log and it seems to unable to find the device…

…but it still appears on the resources:

Here there is a list of the actions that I’ve tried:

• Upgrade RouterOS from 7.21.0 to 7.21.1
• Restore the configuration from an old backup
• Reset the configuration to an empty one
• Downgrade to 7.20.7
• Restore the configuration from the same backup again

---

Is there something that I can try to solve this issue or the modem is gone and it need to be replaced?

Thanks in advance

Bonsoir,

Vous pouvez reseter le modem LTE pour réactiver l'interface:

/system routerboard usb power-reset duration=45s bus=2

Could be issue with modem firmware. Which LTE modem firmware is currently installed? On mine is RG650EEU00AAR01A04G8G_01.300.01.300 - reported as latest on 7.20.7. Try to (re)install latest firmware on ROS 7.20.7 with /interface/lte firmware-upgrade lte1 upgrade=yes maybe it helps.

Also, do not install 7.21.1, there are reports that LTE connectivity is broken for Chateau 5G R17 AX on this version - V7.21.1 [stable] is released! - #5 by ConiKost

Best then to create support ticket to MT on Log into Atlassian - Support (needs separate account). Write in it issue description and attach supout.rif file.
