Re: Yoga 920-13IKB, replacing Qualcomm Aetheros with Intel AC 8265 Wireless card or something better

Yesterday replaced my Qualcomm wi-fi card with Intel 8265.  My Miracast using Microsoft wi-fi wireless display adapter now works ok. 

 

Not sure if my Miracast problem was due to software drivers or the Qualcomm card.  All my drivers & software were up to date.  DxDiag txt said Miracast was not supported.  Lenovo Vantage said all software was current.  Drivers at that time were Realtec 6.0.1.8308, 1709 Build 16299.309, QCA61x4A 12.0.0.325, Bios 5NCN36WW.

 

 

Today I'm using Realtec 10.0.16299.15, 1709 Build 16299.309, Intel BT 20.40.0.4, Intel 8265 20.40.0.4, Samsung 10.0.16299.251, Intel UHD Graphics 620 23.20.16.4849.  Note the Intel card has 2 new drivers dated 3/20/2018.

 

Intel 8265 install was very easy after reading our community articles & viewing YouTube & Lenovo videos.  Battery cable plug & 15 screws very, very small.  Thanks to you all.  System running fine now.

I'm glad it worked changing the card, but Miracast works fine on my Yoga 920 with the original QCA61x4A and the same drivers you had.

DxDiag.txt does not show any problem either. Would be interesting to know what was causing the problem on your machine.

Re: Yoga 920-13IKB, replacing Qualcomm Aetheros with Intel AC 8265 Wireless card or something better

Hi folks,

 

How did you guys disconnected the battery prior to switching the card ?

. Grasped the bundle of battery cables and pulled ?

or

. Grasped the battery connector and pulled ?

or

. Went directly to switching the card without bothering with disconnecting the battery ?

or

. Any other method ? ? ?

 

I'm curious. Thanks

Re: Yoga 920-13IKB, replacing Qualcomm Aetheros with Intel AC 8265 Wireless card or something better

I tried unplugging the cable without taking the 4 screws out from the battery.  But I didn't have enough room, so took the battery screws out.  Then got my wife's smaller fingers on each side of the plastic plug as I held the battery up.  Wiggle the plug back & forth.  Don't pull on the wires.  There is a groove on the outer edge of each side of the plug to help you pry the plug out.  Don't use a metal tool.  The + & - plug is hot.  Find a wood/plastic tool, if needed.  That darn piece of tape kept falling down so I had a hard time seeing, so I used a small piece of tape to stick it out of the way until I replaced the battery.  

 

The real fun starts when you try to fastern the antenna wires back on a wi-fi card.  They are so tiny.  They come off easy, but snapping them back on takes patience.  Remember to possibly flipping them.  Pay attention to the black & white, main & aux.

I'm pretty sure you don't need to disconnect the battery. You just need the special hexagon screwdriver and a Philips head screwdriver. Then carefully pull out the black and white wires from the network card and replace it. Carefully push the wires back correctly. Remember where the wires were connected.

Re: Yoga 920-13IKB, replacing Qualcomm Aetheros with Intel AC 8265 Wireless card or something better

I'm sure you do not have to remove the battery, like I did.  I took the 4 battery screws out to give me more room so my wife could get her finger nails in the two slits/grooves in the side of the battery plug.  I don't think pulling on the cables is advised.  You don't want to dislodge the cables fron the plug.  I'm sure disconnecting the battery plug is good advise.

 

Here's Lenovo's printed instruction text and videos for most take apart operations.  After taking the bottom off, disconnecting the battery is always step 2 for working on almost all components.  But I just hate sparks.

Re: Yoga 920-13IKB, replacing Qualcomm Aetheros with Intel AC 8265 Wireless card or something better

I'd think @Sahil_007's comment is correct. I changed the wireless cards to intel 8265 & 9260 on the Yoga 920 & the XPS 13 without disconnecting the battery. Not that I did not try Smiley Frustrated. After several attempts, and frustrations, I found some info either on Tom's Hardware and/or AnandTech (don't remember). The said info did not mention disconnecting the battery.
However, I admired @kentkrogh's method. That would be the way to go if I should need to do further work, such as replacing the hard drive or so.
As far as the antenna wires's connectors. Surprisingly I had no trouble at all, with a magnifier and headlamp. In fact, that was the easy one for me. The concern when I started was the correct location. Info on the net said the wire connectors are reversed between the Intel and the Qualcomm and/or the Killer. Others said it does not matter which wire go to which connector. So that how I did mine.
It was fun !

Re: Yoga 920-13IKB, replacing Qualcomm Aetheros with Intel AC 8265 Wireless card or something better

I confirm Intel 8265 install was very easy. I did not deinstall any Qualcomm Drivers and I did not have to download any Intel drivers. I did not touch the battery - unplugging is unnecessary. Without Internet connection Windows installed correct drivers. Took me 10 minutes altogether using the E-Durable 26 in 1 Multi-Tool Screwdriver Set from Amazon.de. There is a snap fixture in the middle of the computer's backplate - just pull, you won't damage anything. Can be inconceivably replaced later on in case of a warranty incident. Outcome is staggering - WiFi throughput more than doubled !!!

Re: Yoga 920-13IKB, replacing Qualcomm Aetheros with Intel AC 8265 Wireless card or something better

I see different results on this thread.

Reconnecting the antenna wires is not that easy, but I managed to do it.

 

Anyway I got another problem trying to use the Intel 9260 NGW that I ordered from Amazon.

They shipped me a FRU P/N 01AX769 at EC 1837607.

Installed Intel Drivers PROSet 20.40.0 dated March 20, 2018 downloaded from Intel.

I tested the Wi-Fi speed by copying a windows 10 ISO file from my desktop to the Yoga 920 using my Home Network and got a speed around 700Mbsec while with the Qualcomm Atheros QCA61x4A I get around 320Mbsec. 

Unfortunately with the Intel 9260 Miracast did not work at all and failed to connect to my wireless dis[play Samsung 6 Series 40.

I had to reinstall my original Qualcomm Atheros QCA61x4A to get Miracast to work correctly. 

I could not find any solution for the Miracast problem and decided to return the Intel 9260 to Amazon.

I see other pictures on Amazon for the Intel 9260 showing different FRU and EC levels, but I don't know if they have anything to do with the Miracast issues.

Re: Yoga 920-13IKB, replacing Qualcomm Aetheros with Intel AC 8265 Wireless card or something better

I bought the Intel 9260 from eBay.... It took half a month to ship (from shenzen, China) but it was worth the wait. Miracast, Bluetooth and wifi works just fine. In fact, I noticed a slight improvement in WiFi responsiveness.
