Bug#800703: linux-image-amd64: ath10k not working with Atheros QCA6174 wireless network adapter
Package: linux-image-amd64
Version: 4.1+67
Severity: normal
Tags: patch
Dear Maintainer,
the ath10k module, included in the kernel since 3.11, does not work for the
respective wifi adapter on an Acer VN7-571G.
Kernel 3.16, 4.0, 4.1 and 4.2 have been tested.
Following the discussion here:
https://bbs.archlinux.org/viewtopic.php?id=196519
the problem seems to affect only a specific release of the available Atheros
adapters (168c:003e)
dmesg gives following messages:
