Description Panic 2022-06-02 07:57:20 UTC

I've recently bought the new [2022 Razer Blade 14'' with 3070 Ti](https://mysupport.razer.com/app/answers/detail/a_id/5924/~/at-a-glance:-razer-blade-14-(2022)-|-rz09-0427x).

Unfortunately after installing Ubuntu 22.04 Desktop I've quickly come to realize that neither WiFi nor BT are working.

Can anyone help me with resolving this issue?

Edit: I tried Ubuntu 18.x, 20.x, 21.x, 22.x and fedora 36 with all various kernels and it all shows the same errors. Looks like only Windows has the drivers for the recent hardware.

Edit: I tried copying the drivers from https://github.com/kvalo/ath11k-firmware but its for WCN6855 and not the WCN6856 in my Blade 14''.

Comment 1 Kalle Valo 2022-06-29 16:20:33 UTC

From the driver point of view WCN6855 and WCN6856 are the same. The issue is this error message:

[ 3.466553] ath11k_pci 0000:02:00.0: failed to fetch board data for bus=pci,vendor=17cb,device=1103,subsystem-vendor=11ad,subsystem-device=a82d,qmi-chip-id=18,qmi-board-id=255 from ath11k/WCN6855/hw2.1/board-2.bin

This means that the board file for your device is missing. I need to find the correct board file for your device and add it to board-2.bin. I will update here when I find one.

For the bluetooth issue you need to file a new bug report. One issue per report, please.

Comment 2 lonelyfloat 2022-07-15 21:42:54 UTC

I have the same issue, any update on this?

Comment 3 Panic 2022-07-18 06:49:13 UTC

This has been resolved with: https://bugzilla.kernel.org/show_bug.cgi?id=215946#c1

Comment 4 lonelyfloat 2022-07-19 02:47:53 UTC

I assume that's the board-2.bin file attached? I'll see if it works tomorrow, as it's late for me right now.

Comment 5 lonelyfloat 2022-07-20 01:17:09 UTC

Using the boardfile in that post gave me this error (output from `dmesg | grep ath11k`) :

I just put the board-2.bin in /usr/lib/firmware/ath11k/WCN8655/hw2.1/ ? I want to make sure it's not just my issue.

Comment 7 Shengyu Qu 2022-09-27 06:01:55 UTC

Kalle has just updated board-2.bin in his git, you can check if this works. https://github.com/kvalo/ath11k-firmware/blob/master/WCN6855/hw2.0/board-2.bin

Yes, this should work now. Please reopen if otherwise. Marking the bug as fixed.

Comment 9 Panic 2023-03-08 10:29:17 UTC

I always copy the hw2.0 folder from WCN6855 over the existing one on disk and that works for me.
