On the Surface Go, the standard firmware from the official Linux Firmware repo has issues with the
`ath10k` QCA6174 Wifi device.
You will see messages like "Can't ping firmware" *TODO - Copy messages from console*
You will see messages like "Can't ping firmware".
The most effective fix to-date is to remove the `board-2.bin` file or replace it with a copy of the
`board.bin` file.
The derivative in `firmware/surface-go/ath10k/` can configure this, if you set the option
`config.hardware.microsoft-surface.firmware.surface-go-ath10k.replace` to `true`.
_*NOTE:*_ This is destructive, as it deletes all the `board.bin` and `board-2.bin` files for the
`ath10k` QCA6174 device, and replaces them with KillerNetworking's version.
This is the only way (currently) to force the driver to use the new firmware.
For more details, see: https://github.com/linux-surface/linux-surface/wiki/Surface-Go#wifi-firmware
_*NOTE:*_ There's some work to patch the kernel to make it easier to override which firmware file
to use for QCA6174, which would obviate this more-destructuve approach:
- https://github.com/linux-surface/kernel/commit/22ef83836c4aa89e9eb98de9b47ed24b6c2a1d45
_*NOTE:*_ There was an attempt to get this firmware incorporated into the aggregate `board-2.bin`,
but (as of this writing) the request appears to have been ignored:
