When I connect HUAWEI E169 USB HSDPA modem to RB 411U, on first boot, i can’t see the modem.
when i reboot the router, USB port appears and ppp interface appears. when tryed, the connection to internet works properly.
When power loss is simulated, and RB boots up, the usb port is there but RouterOS says it is invalid. The connection doesn’t work. It says ‘can’t connect to USB port’
again, when i reboot the router,
somethimes the USB is here and everything works fine
somethings a new USB port appears and a new disabled ppp interface appears.
usb port is invalid on every simulated power loss.
RouterOS version is 3.28
