Hey all, newbie to Linux/Manjaro here. I'm having an issue where when I lose my WiFi, my computer fails to reconnect; I've resigned myself to restarting the computer in order to get the connection back.
I'm running Manjaro Cinnamon, Kernel: 4.19.66-1-MANJARO x86_64
Any advice about what I can do to fix this issue would be appreciated. Thanks in advance!

Install and test many of the most recent kernels. Test at least kernels 5.1, 5.2 & 5.3. Install kernels through Manjaro Settings Manager, and always have at least two kernels installed at all times for safety.
Try this:
Disable MAC Address Randomization with the following command:
echo -e "[device]\nwifi.scan-rand-mac-address=no" | sudo tee /etc/NetworkManager/conf.d/disable-random-mac.conf
After creating the new conf file, reboot both your router and your computer.
Try this:
Repeat this command up to 5 times after you have been disconnected to see if the network reconnects:
sudo modprobe -r mwifiex_pcie; sleep 3; sudo modprobe mwifiex_pcie
If there is no improvement, then run this command:
sudo systemctl stop NetworkManager; sudo ip link set wlp1s0 down; sudo modprobe -r mwifiex_pcie; sleep 3; sudo modprobe mwifiex_pcie; sudo ip link set wlp1s0 up; sudo systemctl start NetworkManager
You may want to repeat that command as well.
Please post any outputs of those commands.
Try this:
Lock your Wifi connection to one BSSID.
You can do this in Network Manager's "Wi-Fi" tab in your connection's properties settings.
There is a "BSSID" drop down field where you can select and lock your Wi-Fi to a single BSSID.
Disable Network Manager's WiFi power saving features with the following command:
echo -e "[connection]\nwifi.powersave = 0" | sudo tee /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
Disable Active-State Power Management (ASPM) via a kernel boot parameter:
sudo sed '/^GRUB_CMDLINE_LINUX_DEFAULT=/s/"$/ pcie_aspm=off "/g' -i /etc/default/grub
After adding the boot parameter and saving your changes, run:
sudo update-grub
Then reboot, and if there is no improvement reboot several more times just for good measure.
Test each fix one at a time so you know which change resulted in any improvement.
Same Problem here on Surface Pro 3, Kernel 5.2.11-1.
Did try disabling MAC Address Randomization, however before the reboot my system went on Sleep and woke up without the network connection.
Worked here. Output: Cannot find device "wlp1s0"- still worked. Forgot to try the second line of commands before, though.
Output:
[connection]
wifi.powersave = 0
Seems like that did the trick - I'll watch it and edit if something changes.
Sorry, hit Save too early. Newbie 
You need to substitute your own device ID in place of "wlp1s0". You can find its designation with:
inxi -n
wlp1s0 actually is the right ID. However, it seems to be renamed from wlan0 or something like that. I don't remember where i saw that.
And oh, turning off MAC randomization did not help, unfortunately
If you have no network connection after waking from sleep, this can usually be corrected by writing a service.
Just found out that disabling the wifi manager's power saving feature also did not help that much.
What exactly are the side effects of the ASPM-Idea?
Writing a service could be a good idea, too.
On a laptop it may result in marginally less battery life as it will use a little more power. Those who had used this on a laptop, had reported it wasn't a big issue.
Did not help either, unfortunately.
I will try the service-thing next. At least the restart-line is a good help.
What could but must not be clear is that bluetooth seems to have the same problems. Also with wifi: Nothing regarding the Wifi-connection does work, so i guess that the wifi-chip has its problems.
Yes, it certainly does.
Could you please post:
modinfo -p mwifiex_pcie
No answer on this one.

Apparently my command to display the adapters settable parameters returned nothing because there is no user configurable parameters.
This sometimes helps after sleep/hibernate, but sometimes it hangs at sudo modprobe -r mwifiex_pcie and a reboot is necessary.
(So far) it works reliably when I run the first half before sleep/hibernate, and the second half afterwards.
Basically I modified a script I found on reddit that used to work for Ubuntu (but not Manjaro), from
#!/bin/sh
case $1/$2
in pre/hibernate)
modprobe -r mwifiex_pcie
modprobe -r mwifiex
sleep 0.5
echo "1" > /sys/bus/pci/devices/0000\:01\:00.0/reset
sleep 0.5
echo "Going to $2..."
;;
post/hibernate)
echo "Waking up from $2..."
echo "Reload Wifi Driver"
echo "1" > /sys/bus/pci/devices/0000\:01\:00.0/reset
sleep 0.5
modprobe mwifiex
modprobe mwifiex_pcie
;;
esac
to
#!/bin/sh
case $1/$2
in pre/*)
systemctl stop NetworkManager
ip link set wlp1s0 down
modprobe -r mwifiex_pcie
sleep 0.5
echo "Going to $2..."
;;
post/*)
echo "Waking up from $2..."
echo "Reload Wifi Driver"
sleep 1
modprobe mwifiex_pcie
sleep 1
ip link set wlp1s0 up
systemctl restart NetworkManager
;;
esac
exit
and put in into /lib/systemd/system-sleep/SP3sleep.sh. Maybe a service would be better?
Regarding the random WiFi connection losses,
[connection]
wifi.powersave = 2
is reccommended on various sites and works as well (allegedly wifi.powersave = 3 is the default value)
That is the old method to rmmod modules before suspend and modprobe them at resume. It still works, but it is discouraged as it has been deprecated. The recommended method these days is to use a service.
I have a thread with many examples of suspend services for wifi and bluetooth:
If your method is working then that's great. However, learning how to write services will be far more beneficial in the long run.
