[Bug 1360749] Re: Centrino Advanced-N 6200 Not Sustaining Wireless Connections

[Lonnie Lee Best]

I haven't tested newer kernels yet, but I may have fixed this by chosing
the "Ignore" option for IPV6 in the Network-Manager.

I did this after seeing this in the logs:

Sep 17 20:52:40 computer1 kernel: [ 8708.176663] IPv6: wlan0: IPv6
duplicate address fe80::227:10ff:fe15:55c1 detected!
