Set of drivers for Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter includen into Samsung Galaxy Book 12.0 w720 (https://www.samsung.com/us/support/owners/product/galaxy-book-12-wi-fi) that enable WiFi support on Linux.

Script content and behavior

sudo mv /lib/firmware/ath10k/QCA6174/hw3.0/board.bin /lib/firmware/ath10k/QCA6174/hw3.0/board.bin.bak

sudo mv /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin.bak

sudo cp ./QCA6174/hw3.0/eeprom_ar6320_3p0_TX8_clpc.bin /lib/firmware/ath10k/QCA6174/hw3.0/board.bin

The QCA6174.sh script renames original board.bin file and overwrites with the right version. Moreover it deletes, eventually, the board-2.bin file.

How to use

• Clone the repository
• Enter in the directory
• chmod +x QCA6174.sh
• ./QCA6174.sh

PS: On Manjaro Linux you need to re-launch this script after every update of linux-firmware package.

qca6174-samsung-galaxy-book-12-w720's Issues

Same mac address?

Hello. I'm not sure if this is an issue with this firmware or not.

Generally I've found this firmware to be a vast help. I used to patch kernels with some "fixes" for my w720 and w727v's. But performance was usually pretty not-great. I don't have specifics now.

Anyhow, I've been using & enjoying these blobs for a good bit now. But, when I have multiple laptops going, they seem to have the same mac address semi-often.

I've been using iwd for wifi connectivity, and iwd thankfully has mac address randomization as a built in option (AddressRandomization=once in /etc/iwd/main.conf). Turning on this option has made my laptops all work. But it's weird to me that all my laptops have all started using the same mac address. I haven't tried restoring backups but I feel like this may be an issue with this firmware.

At the moment I'm not sure entirely why I'm opening this issue. This may not really be an issue. This may be operator error. But I suspect there's some real issues here, and at least mentioning this issue may be useful/good. There are some good options for mac address randomization out there.
