what about

dmesg | grep -i 'ath10\|atheros'

And have you looked at any of the other posts?

This first one is more or less what we would walk through anyways .. so give it a go.

I really dont know what to do

#5

There are many fixes listed on the links @cscs posted. I'm pretty sure one of those fixes should help with your issue as almost every known fix for this adapter is given in those links. You should be testing every fix suggested on those links not just the marked solution.

Try this:

sudo systemctl mask tlp

Reboot after running the command.

If it is of no benefit then repeat the command using "unmask" instead to re-enable tlp.

Test this command:

nmcli networking off; sudo systemctl stop NetworkManager; sudo ip link set wlp1s0 down; rmmod -vf ath10k_pci; rmmod -vf ath10k_core; sleep 5; sudo modprobe ath10k_core ath10k_pci; sudo ip link set wlp1s0 up; sudo systemctl start NetworkManager; nmcli networking on

Please post the input and outputs of all those commands.

Be sure the LAN cable and any USB wifi dongle is not connected while troubleshooting your internal Atheros Wifi.

Please answer all the following questions if you would like to get your issue resolved.

Have you tested your wifi on other networks or with different AP/Router?

Have you tested on the live environment with a different DE to see if the connection behaves differently. Record the linux-firmware version and the kernel from any boot disk that performs adequately.

Have you tested alternate kernels? Install and test multiple kernel versions and list all tested.

Have you tested alternate firmware? Test firmware from Kvalo's Github website.

Please list any and all fixes you have tested. Details, details, details.

If none of these suggestions correct your issue pease post:

masking tlp does not work
you should ask to uninstall it.
if not worked reinstall.

Hi thanks for the reply

sudo systemctl mask tlp

seems to have done the trick .. however its low signal but as long as it works I'm fine .. if it does not precisest I'll try the rest of your recommendations

as for your questions before posting on the forums

  • I did try it on different networks, router as well as resetting and messing with my routers several times

  • I did try it using a live usb of Manjoro and Fedora to test it as well as an install of Manjaro, Fedora and Arch all using Gnome DE. for all the installs my wifi works fine at first and then it starts giving me these problems and for the longest time my solution was just to get a fresh install when that happen.

  • on Manjaro I did try it with diffrent kernel versions

  • I did try different firmware including Kvalo's

  • For this install all I did was changing the firmware and whats mentioned on this thread

I'll mark this solved .. if anything changes I'll let you know

Thank you so much for the help
