Qualcomm Atheros Wifi: How to fix it on Linux

26th November 2019 — by That IT Guy0


Unfortunately, it’s a pretty common issue (it seems) for Qualcomm Atheros devices on laptops not working properly under Linux Mint / Ubuntu (and potentially others but this fix is specific for said OSs).

The cause for this issue is power management for Qualcomm Atheros devices. I’m assuming this doesn’t happen for every Qualcomm Atheros device… ever, but I’ve certainly seen it happen on Laptops for the last year or two now (even Kernel 5 doesn’t seem to fix this).

Fortunately, it’s a very simple fix once you know this. Unfortunately, if you don’t know this it’s a bit of rabbit hole of all sorts of tests, diagnostics, sanity checks, etc that can be done with all sorts of Wifi related issues. But since you’re here, hopefully this will solve the issue for you.

Disclosure: If this has just started happening to you on your Qualcomm Atheros device, this will not be the fix for your issue as this issue happens from the word go, it’s not something that works fine for a month and then starts being an issue.

  • First, edit the default-wifi-powersave-on.conf file
sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
  • The file’s second line should indicate: “wifi.powersave = 3“. Change it to 2 and reboot.
  • Once back up, make sure the power management for the wireless device is indeed off by running the following command.

Within the information shown, one line should now read “Power Management:off“. If so, the issue should now be hopefully resolved for you.

Mint themes: How to install them on Ubuntu

19th November 2019 — by That IT Guy0


If you’re like me and use Linux Mint as your everyday desktop OS of choice, you’re used to a certain look (be it XFCE, KDE (for older releases) or most likely, Cinnamon) provided by Mint themes.

At work, I use a Ubuntu Server (with a Mate Desktop) with one single Desktop application (the why, when or how isn’t important here). I have this VM in full screen (on a separate monitor).

I’ve recently started using Mint themes (Mint-Y Dark theme) for Mint and while I like it, the difference between this and the screen next to it is annoyingly obvious. The one Dark theme on Ubuntu Mate desktop is blatantly inferior (in my opinion at least) so, what can we do?

We can install Mint themes on Ubuntu. Please note that I’ve only tested this on Ubuntu 19.04. I have no idea if it’ll work on older versions. So, to do this, follow these steps:

Create a new .sh file and open it:


Copy the following in:

mkdir ~/mint-themes
cd ~/mint-themes
sudo dpkg -i mint-x-icons_1.5.2_all.deb
sudo dpkg -i mint-y-icons/mint-y-icons_1.3.4_all.deb
sudo dpkg -i mint-themes/mint-themes_1.8.2_all.deb
cd .. && sudo rm -rf mint-themes/

Make it executable and run it:

sudo chmod +x
sudo bash

You’ll now be able to find the Mint themes in both areas you’ll need to change them within Ubuntu (“Appearance” and “Window Manager”).
