I recently purchased a Dell Inspiron 7567, and added a dual boot of Ubuntu Mate, version 17.04.

For some reason, my wireless seems to randomly disconnect every so often. I haven't noticed any new icons on the wireless icon in the top of the screen.

It will usually happen whenever I am web browsing, and I will be forced to close the tab and re-open in order to load a page. It will also often happen when I am trying to download something. It will be downloading at a steady 1.5 MB/ps or so, and then slowly ramp down to 0 B/s.

This issue appears both when I am using Firefox which comes pre-installed, as well as Google Chrome.

This issue does not appear when I use Windows 10.

My specs:

  • i5-7300HQ
  • 8GB RAM
  • GTX 1050

Output of sudo lshw -class network:

Any help would be appreciated!

I had the same issue with an Inspiron N7110. After doing significant digging, I think I found the culprit. It's the 2-in-1 Network/Bluetooth card. While I can't promise its going to work, after making these changes it functions perfectly now.

First, stop the service:

sudo systemctl stop bluetooth.service

Then disable it:

sudo systemctl disable bluetooth.service

Check:

sudo systemctl status bluetooth.service

Turns out simply updating from the old 4.10.something kernel which Ubuntu comes with to either 4.12 or 4.13 fixes the issue. For some reason 4.11 refused to properly install, but that doesn't really matter since its outdated anyway.
