[Solved] I lost WiFi with the latest updates

Postby BostonPeng » 25 Feb 2018 19:28

A day or three ago I got updates to SolydK and took them, and after I shut down my computer and rebooted the next day I discovered that I no longer have WiFi, only my wired network connection.

Long time no see!

There has been a kernel update a few days ago but I'm only guessing.
You could try to boot from the previous kernel and check if that fixes your wireless.

Could you also post back the output of these commands:

Code: Select all

inxi -r
sudo iwconfig
cat /etc/network/interfaces

I should have said there was a kernel update right before the issue started. I'd actually been going back three or four kernels because my system kept locking up. Often I couldn't even get to the home screen before my system locked up, and I'd been meaning to post something about it but never got a chance to do it when I thought about it.

Code: Select all

$  inxi -r

Your card is not recognized: iwconfig does not show a wlan device.

I searched for "MEDIATEK MT7630e debian firmware" and found:
https://packages.debian.org/stretch/fir ... sc-nonfree

Check that you have firmware-misc-nonfree installed or install from backports and see if that worked:

Code: Select all

apt install -t stretch-backports firmware-misc-nonfree
If that doesn't work, you'll probably need to compile your own driver:
https://github.com/neurobin/MT7630E
There are instructions, but obviously I cannot predict the results :(

I did have to compile it but it's working now. Thank you! I think I once again have a really well-working install of SolydK! I was thinking I needed to back everything up and do a clean install, something I was not looking forward to.

I'm glad it eventually worked.

Could you please put "[Solved]" in the OP's subject?

Will do, in fact, I just remembered about that as I clicked the email link to read your post.
