Seems there is something interesting I have found:
Product Brief for 7260AC Dual Band:
Now the new Intel 7265AC (apparently Broadwell 5th gen only, have not seen anyone who has it, but the product brief says low power modes....Microsoft InstantGo????)
Hope its not a hardware only fix to be implemented in 5th gen systems, what happens to everyone on 4th gen haswell??????
Could it be the Intel Power Optimizer????
I just upgraded my Vaio Pro from the stock 7260 to a 7260AC Dual Band M.2 card, experiencing same issues people are reporting, wake from sleep 17 series drivers, Error Code 43. Revert to 16x series seems fine but instead of over 40MB/sec transfer, down to around 20-30MB/sec. Intel does need to sort it out, Vaio Pro (Sony) had lots of complaints from this during initial release. Seems the stock 7260 non AC has had alot of work done to make it work properly, but not the AC variant?
I just want it solved so no resetting, no redetect, just make it work like it should!
Cheers,
