FWIW:

 

This Y2P shipped 23 Sep 2014.

WiFi Card is "Intel(R) Wireless N-7260"

Driver is listed as 17.0.3.3 w/ date of 05/26/2014

 

I think some were suggesting that the Y2P was shipping with AC cards installed. Although I read many threads at work, and I might be mistaken about that being in this thread.

 

So far witth a sampe of onw home router, WiFi has been quite stable. Streaming HD from my SageTV backend, streaming music from a NAS and installing updates / software etc...

 

Gona see how it behaves with my rooted phone access point.

 

online it is N, in stores it is AC

I read someplace -- and I've read a lot of posts on different forums, so can't recall where -- that the Best Buy contract with Lenovo has exclusive dibs on the upgraded CPUs and AC WiFi adapters until some time this fall, so probably in a few months the units shipped from Lenovo will also have the upgrades.

By that time, Best Buy will probably have Yoga 3 Pro on their shelves :)

Will upgrading my Yoga 2 pro Wireless card void warranty? 

I purchased my yoga 2 pro Dec 2013 so it has the original Wireless N card in it. I can't currently scan or connect to any 5GHZ connections? is this possible with any drivers? or would i have to upgrade the hardware.

The original wireless N card you have installed from the factory will not work for 5GHz (AC) WiFi, you will need this card. I beleive the consensus is that swapping the card does not void the warranty. However in the event you need to return your unit for repair you may want to swap out the card back to the original one. The Intel drivers you have installed shoud work with the new card (Lenovo has some updated drivers posted on their support site however).

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 https://downloadcenter.intel.com/Detail_Desc.aspx?lang=eng&changeLang=true&DwnldId=23994
*



*- 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?

Installing intel's generic driver has proven to be worst than Lenovo's crappy drivers. I personally would stay away from those drivers.

Can't say thanks enough for this piece of guidence.  This was totally the solution to the problem i had.. I was almost ready to go get a new card.   Thanks very much for figuring this out.  If only Lenovo would list the driver as the fix, I wouldn't have wasted days trying to figure it out also.

Update to those waiting: 17.0.1.5 has had 0 limited wifi connectivity and my card+driver has undergone several stress test.

 

The driver I am referring to can be found on this page: http://download.lenovo.com/consumer/mobiles/wifi245w8164.exe

 

Be sure to install this version to get the right OEM ini file. Else, a generic driver (with the same version number) will be as unstable as previous drivers.
