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:

enp6s0    no wireless extensions.

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

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.
