Comment 68 for bug 1520343

I'm using a Killer 1535 on kernel 4.5.0 and the updated files as per post #1, and I get the same dmesg as Dennis posted in #66 after initialisation:

I can connect to 5GHz SSIDs, however I see very unstable ping and high packet loss even when the link is otherwise idle:

526 packets transmitted, 221 received, +9 errors, 57% packet loss, time 525820ms
rtt min/avg/max/mdev = 2.244/93.484/1691.704/201.948 ms, pipe 3

Using the same SSID but using Windows 7, or a 2.4GHz SSID on , normal performance is seen, >1% packet loss and >3ms ping.

Any ideas here, have I missed something?
