Since 7.6 I have been having issues with multiple quectel RM520N-GL modems keep disappearing and reappearing form interfaces list. It is happening from 3 wAP R ac units. The issue can be resolved by reverting back to 7.5 stable. the log files shows error "mbim: error: wdm send failed: 19" The modem is running firmware RM520NGLAAR01A05M4G
