I posted a reply about this back in July. Honestly Intel messed up the
integration and drivers for this wireless card. And I imagine that the non
5GHz band on the card spec is questionable from a design perspective. I do
not agree that switching our the hardware will not negate your warranty...
just the opposite, I learned that my support warranty would be compromised
if I changed the hardware and drivers. Re-posting part of my July post...
*There is a 6-26-14 Intel ProSet Wireless software update (one for drivers
only and a full update to the whole setup). So without going into all the
details... Last night I wen ahead and downloaded the full ProSet Wireless
package (87MB) and ran this installer on my Yoga 2.13 (model # 20244) and
this update finally fixed the problem. I have not run a full range of
performance test, but the wifi range and performance now matches other
normally performing laptops in my house... easy download/play of HD videos
and snappy web interaction (an other wifi enabled devices). Here is the
link to this Intel ProSet software
package

*- Use the installer named "Wireless_17.0.5_e164.exe
".
So thank you Lenvoo for trying so hard to fix this problem and curse you
Intel for locking us N7260 Single Band 2.4GZ users in wifi limbo. Happy to
report my Yoga 2 is now finally as awesome as I thought it would be!!
Cheers*
I'll also add that power management controls is something that the Lenovo
tech had me tweak as part of the the solution. So make sure you dial up the
Lenovo power performance (through their special power utility in the
taskbar). Essentially you will want max performance or cinema mode for the
power management setting. I think setting it this way blocks the OS from
cycling down the power to the network wifi card and keeps you wifi active
and powered. Warning this will also consume your battery faster.
All in all - based on all the problems I have seen related to this network
wifi card. I think intel should recall the N-7260 ( 7260 N) wifi card and
give users a replacement that is not so problematic. What a mess. Should we
all be having to trouble shoot this?
