Post by Ultegro778 » Tue May 28, 2019 2:06 pm

hello im using 2 distro Linux Mint cinnamon 19 with 4.15.0.x kernel and Ubuntu mate 19 with 5.0.0.15 kernel. I have problem with my ubuntu in kernel 5.x, when i plug modem it's connect to internet and then disconect randomly. But when i was used kernel 4.15.x in my ubuntu its normal.
so i assume the problem is on kernel 5.x doesn't support my modem. So i initiative to install kernel 4.15.0-041500 to my both os, then i try to connect my modem in Linux mint kernel 4.15.0-041500 it's running normal after that i also try in ubuntu kernel 4.15.0-041500 and i get same problem in kernel 5.x. i don't know where is the problem. please help me. thx anyway

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.
Tune up your LM 19.x: ppa:gm10/linuxmint-tools

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]
linux-firmware/disco,disco,now 1.178 all [installed,upgradable to: 1.178.1]
linux-firmware/bionic-updates,bionic-updates,bionic-security,bionic-security 1.173.6 all
linux-firmware/bionic,bionic 1.173 all
Tune up your LM 19.x: ppa:gm10/linuxmint-tools
