Mudi / GL-E750 / Modem Reboot

Hi, what's the advantage or difference between a modem soft reboot and a hard reboot?

Also, is there any way to fire those commands other than the web GUI? Terminal command perhaps?

I have times when I want the modem to rescan for the best channel(s), I would assume a reboot is best for that?

Thank you!

I am confused. Do we talk about the modem (so LTE) or Wi-Fi? Channels is a term for Wi-Fi …

Modem as in cellular M.2 modules, not the wifi radios.
