Re: Modem always disconect
So to recap, your Linux Mint OS is running fine, your Ubuntu OS that was released a year later is not. Sounds to me like you should be asking for support over at Ubuntu then, this has got nothing to do with Linux Mint.

Sorry i'm ask here because nobody reply my question in ubuntu forum
Re: Modem always disconect
Well, the likely reason is incompatible firmware. Try one of the older versions of the package. Your Mint is using version 1.173.6:
Code: Select all
$ apt list -a linux-firmware
Listing... Done
linux-firmware/disco-security,disco-security,disco-updates,disco-updates 1.178.1 all [upgradable from: 1.178]
