On version 3.105 everything worked fine.
After updating to version 3.215, the device does not see the built-in EC20 modem and says “No Modem device found. Plug in your USB modem to start”
After restoring to 3.105 again everything is ok.
@alzhao Can you help me?
Currently, I cannot solve the problem by buying a new device
Can you send request via email: support at glinet.biz
Pls send via system log
Due to the outdated base system OpenWRT 19.07 I changed the system to clean OpenWRT 22.03
Are you going to update your system to version 22.03 for this device?
For MiFi we will not upgrade the openwrt distro anymore.
