Comment 11 for bug 1293569

I can fully confirm the original reporter's observations. I have a 2nd generation Thinkpad X1 Carbon here with the same wireless card and I had exactly the same symptoms:

* Connectivity losses
* Bad performance
* Once the device uses wireless (e.g. a download), all other devices in the same wireless network experience problems (e.g. very high latency with spikes up to 2000ms).

I've disabled the -8 firmware as described in comment 0 and so far, all issues are gone.
