Aye, i recently moved to Xubuntu 15.04 and from time to time when I wake up laptop from suspend wifi cannot connect. It says networking disabled. I tried turnig on option "Enable networking" but that gives me nothing. I have to restart laptop (and It's also a problem as sometimes turning off or trying to restart just logs me off, i have to turn it off the hard way) and then it works. Any suggestions?

I had a similar problem on Xubuntu, try to run

sudo apt-get autoremove
sudo apt-get autoclean
sudo dpkg --configure -a

Then restart the PC. Also, you can check for additional drivers on the driver Utility.

If the problem persist, look at

dmesg

And attach the output on a text file.

Also, you can see this entry: WiFi Issues

  • Can you explain what those lines does? I like to know :) – WiiTold Jul 24 '15 at 13:15
  • Sure!, autoremove, uninstall all the residual packages left for some programs after updates or other software removal or installation.

    autoclean, erases residual packages from disk, to free disk space.

    dpkg --configure -a: Configure a package which has been unpacked but not yet configured. If -a or --pending is given instead of package, all unpacked but unconfigured packages are configured.

    For more information, you can do : man , for example,

    man dpkg

  • The problem is still on. Here is link to txt output from dmesg https://drive.google.com/file/d/0B08bH1wkIXqGOElIUE53b0dSQXc/view?usp=sharing – WiiTold Jul 26 '15 at 13:31
  • Please, post the result of lsmod , ifconfig and iplink . You can also try the solution given here: [link] (http://www.linuxquestions.org/questions/ubuntu-63/wireless-became-disabled-how-do-i-enable-858357/) at comment #7. Also, you can try the solution given above by Mark Henderson. – GTRONICK Jul 26 '15 at 17:17

  • I dont know if its relevant but i noticed that when I launch my laptop, I dont get DOS screen. Y'know, "Press F12 to run DOS setup" shit. It's going straight to the Xubuntu login screen – WiiTold Aug 13 '15 at 19:26
  • I cannot see the brcmutil or brcmsmac module on your lsmod file. Have you searched for drivers with your driver utility? . Which hardware are you using? PC model, processor, ram, OS version and kernel version. However, here is one solution for this problem, read ahead: Wifi not working after sleep on Xubuntu 14.04 – GTRONICK Aug 14 '15 at 12:52

Yeah, seems a little harsh. Possibly an accidental click?

At any rate, have you tried this:

http://www.techytalk.info/ubuntu-fix-network-stopped-working-after-resume-from-sleep/

And if you are struggling to follow that solution, paste the results of "sudo lsmod" and we can go from there.
