Wi-fi connection problem

marcusvinicius

Hello,

Since I've done the last updates yesterday my wi-fi stopped working. I'm don't know if the problem is related to the updates though, but I also don't know how could I solve it.

Is there any common way of solving those issues? Here are two screenshots of the wi-fi icon:

(I think the exact source string would be "No network connection")

("Ethernet network" appears as disconnected when I click the icon)

There aren't any wi-fi option to to connect, neither if I try to share my smartphone mobile data. Could someone please give me a help here?

PS.: not sure if it can affect it, but I have both Solus and Windows 10 installed)

Are you able to connect your laptop (I'm assuming it's a laptop) via ethernet and see if you have network access? If you do I'd suggest you roll back using this info.

I'm not sure if this will help you, but my wireless connection disappeared after using DoFlicky to install the Broadcom STA drivers and I got it back by running depmod -a and rebooting.

ctriaan, it's not workint here. It appears "depmod: ERROR: openat(/lib/modules... Permission denied" when I try it.

ctriaan

marcusvinicius sudu depmod -a

marcusvinicius

ctriaan, when I try it it appears it also doesn't work because I'm not the owner of /usr/lib64/sudoers (something like that; not know by sure because I have to come to Windows ^^)

Then I tried to give myself permission, but it also didn't work.

ctriaan

marcusvinicius I meant sudo, not sudu.

marcusvinicius

I did it, @ctriaan :\

It appeared:

error in loading /etc/sudo/conf, line 0 to load plug-in "sudoers_policy"
/usr/lib64/sudo/sudoers.so can only be recorded/written (?) by the owner
fatal error, it wasn't possible to load the plug-ins

ctriaan

I don't know how you can add yourself to the sudo group if you don't have permission to do it.

Does anyone else have some advice?

marcusvinicius

@Justin suggestion also isn't working because of the same sudoers_policy issue. Still stuck here ☹️

My way, would be to boot into single-user/emergency mode and correct the sudoers file, reboot into normal/multiuser. Done. You should now have sudo based root authority.
Then you can work on your wireless issue 😉

marcusvinicius

Hey,

I managed to solve the sudo based authority, thanks, dbarron, but I didn't solve the wireless issue. None of the recent updates seem to be wifi-related, so — as a Linux newbie user — I really don't know what else should I try.

I probably will reinstall Solus next days.

Anyway, thanks for the attention and help, everybody ❤️

Did we get a kernel update (I didn't check/notice) since you last updated? That would certainly be wifi related.

I am having a wifi issue on my Dell Inspiron 1521. Some in the latest updates caused it to stop working. I rolled back to a previous update from a couple weeks ago and got it working again. Now, how can I do any new updates without having it break my wifi again?

sataylor56 You used a post where the last entry was 3 years ago, called necro.
As for the question, show wpa_supplicant -v

joebonrichie

We had numerous issues with wpa_supplicant 2.10. We downgraded to 2.9 and backported the security fixes from 2.10. Updating to the latest version should resolve your issues.

Also please don't necro old threads, cheers

Sorry, I thought I was having the same kind of problem and I was followeing the reccommendations in this topic that I should continue here. Anyway here is the result:
wpa_supplicant v2.9

So, yes I am now on v2.9. I'll try updating again.
Thanks
