Problem: Xubuntu 16.04 wireless is not working.

First my system, from uname -a

Linux clessidra 4.13.0-43-generic #48~16.04.1-Ubuntu SMP Thu May 17 13:00:11 UTC 2018 i686 i686 i686 GNU/Linux

result of rfkill list is nothing

Result of ifconfig -a

And then iwconfig:

lo        no wireless extensions.

I've tried to install realteck drivers but no luck here, during install command result:

Error! Bad return status for module build on kernel: 4.13.0-43-generic (i686)

I've tried also to get networking service status, using: sudo service networking status and receive:

mag 27 16:03:03 clessidra systemd[1]: Started Raise network interfaces.

So my question is:

  1. why wifi interface is no more available?
  2. why I'm able to connect using ethernet, but not wifi ? From my perspective, seems to be because no interface has wifi support, right ?
  3. how to install a working driver and have wifi support back ?

Note:

  1. this laptop is old, is a cx620 with model name ms-1688
  2. I don't want to upgrade ubuntu version and stay on xubuntu (that works perfectly in my case until yesterday)
  3. I've also already tried to disabled uefi boot stuff, but there is no option on bios

  • Please [edit] the output of sudo lshw -C network into your post. Thank you for helping us help you! – Elder Geek May 27 '18 at 18:04
  • I've provided requested information, thanks to you! – Vokail May 28 '18 at 16:40
  • VTR as there is now enough information to answer this question. – Elder Geek May 28 '18 at 17:32
  • I see no wireless network adapter listed with which a hypothetical device driver could interface. Are you sure it's enabled (for internal devices) or connected (for external add-on devices)? In the case of an external network adapter, how is it connected to the machine in question? – David Foerster May 28 '18 at 17:38
  • it's an internal device. I wonder if there is a way to check if "hardware button" is stuck or not, because seems not working anymore? – Vokail May 29 '18 at 07:00
  • What's the output to rfkill list? Ping me @fabby after you've [edit]ed your question qnd provided the output. – Fabby May 30 '18 at 21:16
  • @Fabby I've tried to run rfkill list and output is nothing – Vokail Jun 01 '18 at 19:07
  • I've tried also to update kernet and after many problems, go back to 4.4.0-128 with xubuntu 16.04.4 LTS, but problem is still here.. – Vokail Jun 01 '18 at 20:13
  • It is a hardware issue. – Pilot6 Jun 08 '18 at 10:15

Based on your output the reason wireless doesn't work is that your particular laptop doesn't have the optional wifi or if it does, the card is faulty.

The specs are as follows:

• Intel® Core™ i3 Processor  
• Genuine Windows® 7 Home Premium
(MSI recommends upgrade to Genuine Windows® 7 Professional)
• 15.6” 16:9 wide screen display
• Easy-to-carry lightweight design
• ATi HD545V with DDR3 512MB VRAM graphics card
• 802.11b/g/n Wireless LAN with Bluetooth (optional)
• HDMI (High-Definition Multimedia Interface) Output
• Exclusive GPU Boost Technology
• msi Exclusive ECO Engine Power Management System

The fact that it doesn't show up in the lshw command indicates that it isn't there (or isn't connected). If your certain that you have one, visually verify that it exists and insure that it's properly connected.

  • my laptop does have wifi card, at least last week was working. I wonder if it is possible that I have a problem on "activate wifi" button, there is a way from software to test it ? – Vokail May 29 '18 at 06:43

    @vokail if that were the case it would show up with the rfkill list command. The fact that it doesn't show up in the lshw command indicates that it isn't there (or isn't connected). If your certain that you have one, visually verify that it exists and insure that it's properly connected. – Elder Geek May 29 '18 at 14:44
  • I can confirm it – Vokail Jun 01 '18 at 20:42
  • Elder Geek: Your hunch was correct before I asked about rfkill list! @Vokail Don't forget to accept the answer! – Fabby Jun 01 '18 at 23:16
  • Well I'm not sure to understand, my laptop does have wifi-card and is not working, so why accept the answer ? – Vokail Jun 02 '18 at 07:00
  • @Vokail I'm not sure I understand either, it looks to me like my answer is correct. According to your question "result of rfkill list is nothing" I added the content of my comment which it appears that you might not have seen to the answer. – Elder Geek Jun 02 '18 at 21:23
  • I have solved buying a wifi usb adapter, my wifi card seems not working anymore (even if propertly connected). – Vokail Jun 04 '18 at 06:25
  • @Vokail Thats not too surprising, as I indicated in my answer that your card was either missing or broken (faulty). I'm glad you got the problem resolved. Cheers! – Elder Geek Jun 04 '18 at 12:49
