I decided to test Manjaro KDE as my daily driver on my Acer Laptop and so far it has been a great experience. However, the biggest issue I have been facing is that I am not getting full WIFI speeds on my laptop/browser experience. How I can compare is that:
Windows 10 at Home network: Able to test by using fast.com/speedtest.com to see that I am getting 200-250Mbps with no issues.
Manjaro KDE at Home network: On fast.com/speedtest shows me that I am getting at MOST 40Mbps.
I assumed that it might be a Manjaro issue, but when I use Manjaro outside of my home network, i.e. coffee shop, someones house, etc. I am able to get full speeds. I know that these places have full network speeds, since I have used it with my Windows 10 before.
I tried looking at other forums, on Manjaro and Reddit, and its not very clear on what I need to do in order to troubleshoot and find. If the community/someone here can guide me on how to troubleshoot why I am getting very slow speeds when using Manjaro KDE at home, I would love the help and guidance.

Sorry for all the information, this is what I researched on forums to gather information and try to see how to troubleshoot this WIFI issue.
Hey there thanks for the suggestions/advice. I’ll take a look into those links and try to troubleshoot more, but what boggles my mind is that Wifi is only affected at home, but other when using manjaro at other places with wifi it works fine, as I have seen it with my Windows 10.
Is it possible that my router is causing the drop in wifi speeds on my laptop when using Manjaro? Or this is definitely a kernel issue? For note, I am using 5GHz Wifi, where I have my router choose from 20/40/80mhz and I have enabled 160mhz on it also.
@diego1sudo modprobe -r ath10k_pci && sudo modprobe ath10k_pci , this command resolved your issue by resetting the WIFI driver? Did you have to do this every time after you power up/log in to your laptop/PC?
To give you a headsup, I am currently typing this right now with the laptop running on battery, I do not have an external power brick powering/charging my laptop. Would you want me to plug my laptop to see if that Power Save: On changes state?
With that command, I had to add the “sudo” before iw.
Then I retrieved the previous command to confirm it was was off. However, when I ran fast.com or speedtest-cli, it showed me the same issue of being capped at 40Mbps.
Using @diego1 method with the following command below:
I retested this and immediately see my current speed of more than 200Mbps. So that actually solves the issue. How would I implement diego1’s method into a config? Or is that a temporary solution that requires a permanent fix?
Thank you for taking the time to help me with this issue, really appreciate the help and your patience.
See my post above about the service … it would automate that action at login and wake-up.
(the file location and command to enable it are commented at the top)
Or at least it is an example, untested. Theres multiple ways to do it, but that service might work without having to create separate scripts or services.
No worries. We used to have a whole ‘intro to systemd services and timers’ tutorial section … but it was on the old forum. In any case we all start somewhere, and there are still tons of long-time users who dont fully understand how to work with systemd. But this kind of thing is a great example of it being useful.
