Re: QCA6174 hw2.1?

[Gabriele Martino <g.martino@gmx.com>]

Just tried the kvalo's kernel.
NetworkManager connected flawlessly at boot to my WPA2 home network on
2.4GHz. Will try 5GHz later.
iwconfig reports a fixed 1Mb/s bitrate, but I can copy files to my nas
(smb share) at about 3.3MB/s.
That's a reasonable speed for b/g wireless.

iwconfig:
