Lets see if the command can be automated

cd /usr/share/usb_modeswitch/
sudo tar -zxvf configPack.tar.gz

That will unpack the usb-modeswitch rules and hopefully you can reboot, plug in the dongle and use it

What about

Code: Select all

cat /etc/resolv.conf

You may need to

Code: Select all

sudo dpkg-reconfigure resolvconf

Answer yes to enable dynamic updates

I only hear noise on my speakers if I plug the headphones into the microphone jack. The headphone jack on mine is the one closer to the front of the laptop

See what this command shows

Code: Select all

nmcli -f all device show | sed '/^GENERAL.DEVICE:[ ]\+lo$/,/^$/d; /^AP\[[0-9]\+\]\./d'

What does the command route show you in terminal? You have an IP address from your router and can ping outside IP addresses. I don't think this is simply a kernel issue

There doesn't appear to be a bluetooth chipset in the laptop. Go into Sound Settings/Output and see if the headphones are shown after plugging in

You should go into Network Setting for the wired connection, IPv4 tab and add 8.8.8.8 as a DNS server

Post results from terminal for

Code: Select all

inxi -Fxz; lsusb; dmesg | egrep -i 'blue|firm'; lspci -nnk | egrep -i 'net|audio|sound'

I have a M645 but it didn't come with bluetooth and the headphone jack works fine

It might be a DNS/DHCP issue, can you ping anything?

Code: Select all

ping -c3 8.8.8.8

Or able to ping the router? ping -c3 192.168.0.1[/code]

Try

Code: Select all

eject /dev/sr1

See if lsusb results have changed

What is result for

Code: Select all

ls /dev | grep sr

Post results for

Code: Select all

lspci -nnk | grep -iA3 net; lsusb

It might be best to stick with the 4.4 kernels from the Update Manager if your equipment works with it. Anything higher than 4.13 will risk breaking dkms modules from the repos as Ubuntu hasn't patched them for 4.15 as Ubuntu 16.04.5 will be released in August with the 4.15 kernel

There were some issues with 4.15.0 kernels from Ubuntu as they had an unversioned dependency on linux-base and the 4.15.0-20 kernel when installed with the update manager wouldn't install the linux-modules-extra package. It seems that the linux-base version issue was fixed in 4.15.0-22 and the linux...

If you used the Mint Update Manager to install that kernel, do a refresh and see if there is an update for the update manager as this problem should have been fixed

Download http://security.ubuntu.com/ubuntu/pool/ ... _amd64.deb and transfer the file to the linux mint desktop, then double click to install, then reboot

Reboot and use Grub Menu/Advanced Options to boot into an older kernel, then with working networking do

Code: Select all

sudo apt install linux-modules-extra-4.15.0-20-generic

Reboot

I would do

Code: Select all

sudo apt-get install rtl8812au-dkms

Reboot

I wonder if

Code: Select all

sudo iwconfig wlo1 txpower auto

Might work better
