Know this is an old post but wondering if anyone has found a resolution. Just received a new HAP AC and am using the USB 730L modem as well. USB power doesn't seem to be the issue. As mentioned earlier in this post, all the expected LEDS remain lit. The lte1 interface disappears about every 30 secon...

Is there any update for this? I have the same router with the latest RouterOS, 6.43.12 and metarouter is stuck in booting.

thanks
