Re: Wifi card looses network connection

@Aliverix: I contact them with the mailing list linked in my previous message, I think you can post your information there. Last time they contacted me in private and said that they were unable to reproduce the issue on their D-LINK router, and that they were purchasing the same identical router I am using to investigate further. I didn't test any other version with api 6.

Edit: Dell 9570 wiki page updated.

Re: Wifi card looses network connection

Ok, I will try to contact them on the mailing list then. I have tested version 132 and it is also affected. Thanks for finding the workaround!

Re: Wifi card looses network connection

@snack, thanks - my problem has just returned (another kernel update I guess) so I'm back here to figure out how I fixed it!!  I couldn't figure out how to join ifradead.org, but for the record I have Ubiquiti Networks access points, which for all other client devices (including with linux)  have been rock solid reliable.

Re: Wifi card looses network connection

@blake5634 If you allow for contacting you in your profile then I will send you the email of the developer taking care of the bug so that you can contact him directly.

By the way, I changed the router due to a change of ISP, and still did not try what happens with the buggy firmware. In case it does not show any problem then I'll not be able to provide more feedback for debugging.

Re: Wifi card looses network connection

I have created a Pacman hook so that the file is automatically deleted after every linux-firmware upgrade.

/etc/pacman.d/hooks/firmware-6.hook

# Removes the updated firmware for the wifi card on Dell XPS 15 9570 to prevent a bug

[Trigger]
Operation = Install
Operation = Upgrade
Operation = Remove
Type = Package
Target = linux-firmware
[Action]
Depends = coreutils
When = PostTransaction
Exec = /usr/bin/bash -c "if [ -f /usr/lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin ]; then /usr/bin/rm /usr/lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin; fi"
