All,
I didn't look at all the threads so I apologize if this has already been covered. I have an Elitebook Folio 1040 with the 7260AC card. Like everyone else I was seeing terrible throughput, ping times were all over the place and random drops were common place. Tonight I disabled U-APSD support and I have been doing great ever since. Ping times are consistently 2ms (high as 300ms before) and no drops. I'm running the 17.0.5.8 driver. Hope this helps somebody else.
