[Solved] Wifi stopped working after package updates on Lenovo ThinkPad

Post by Me65 » Thu Aug 08, 2019 4:45 am

I am using Linux Mint for quite some time now and did not have any real problems with it, but after doing some updates I cannot connect using Wifi anymore (Ethernet works fine).

My device is running Linux Mint 19.2 Cinnamon since I upgraded it last friday and everything worked until I experienced problems yesterday evening. In the morning I had updated the following packages, where some of the changes kicked in after the reboot and seem to produce problems now:

Code: Select all

libsystemd0
systemd
libpam-systemd
libudev1
libudev-dev
udev
systemd-sysv
ndiswrapper-dkms
ndiswrapper
The kernel version is 4.15.0-55-generic.

I already tried reinstalling the current kernel version and the ndiswrapper* packages (which did not show an error during installation), but after rebooting this has not changed anything at all. As it is an older Lenovo ThinkPad, I also made sure that the hardware switch is not disabled - it is active.

How can I fix these problems?

Code: Select all

$ inxi -Fxz

Hello Me65,
It would help to know which thinkpad you have and what wireless card it has in it. My thinkpad has intel card which is supported very well.
Try this command

Code: Select all

inxi -Nn
post the output.

It is a X220 one and seems to use an Intel card as well.

The output of inxi -Nn is

Code: Select all

Network:   Device-1: Intel 82579LM Gigabit Network driver: e1000e 
           IF: enp0s25 state: down mac: 3c:97:0e:04:a8:69

here is a page that may be of help. https://easylinuxtipsproject.blogspot.c ... s.html#ID1
Something is blocking the wireless card. as it's not being detected at all.

Maybe #1.3 on that page?

I do not know why, but without changing anything it works again. I will keep an eye on it in the future.

Thanks anyways.
