With the Realtek card I have noticed some stuttering issues in every network (with all the three drivers I have mentioned here earlier). Some "No internet connection" messages now and then in Chrome which aren't a big deal, but it's really annoying to use ssh to control my other computers. SSH (Using puTTY) hangs for a few seconds almost every minute. The network never disconnects though.

No reaction from 'teflon' Mark_Lenovo anymore ....
No support from the regional service organisation ....
My Yoga turned out to be a disaster product with nonsufficient service.
I will return my 6 months old product tot the reseller next Friday to get my money back.
If not, I will smash the Yoga to pieces just outside of the shop.
Showing other customers to buy any other brand.

When last I updated, I was awaiting arrival of the back ordered wifi card. We ordered one, and after calling parts and confirming the part number and checking availability over the phone, I found the same thing that I had already been told - that is was on back order.
I promised I would update once I had the card in hand and could confirm it installed and worked as development has communicated to me. I've been waiting on the card.
Alas, cards came in yesterday, but there seems to be an issue in the logistics as the cards which were received were not the ones which we had ordered. Different part number and connector type. We confirmed the part numbers that were ordered, and don't know if there was an erroneous substitution in the system, or just what happened. We are in the process of investigating this, and re-ordering the part.
Again, once I have the card, I can update this thread. Until I do, I'm not sure what else I can say about it as I've shared the information made available to me on this topic.

This is the Lenovo OEM Intel 7260AC card in the Yoga 2 13 with BIOS version 1.09 !

It's deadly quiet in here.
Could it be a secret mission?
Maybe Lenovo is waiting for Black Friday and will surprise us with a free 20200617
when customers join their Lenovo Y3P-corner and handover their 7260N cards?

I am also waiting for some resolution on this. The wi-fi on my Yoga 2 13" is just terrible. I have to be in the same room as my router. It's worse than the 5-year-old Asus laptop I replaced.
What wifi card do you have?
I'm mainly interested in upgrading to an AC card, but I don't have any complaints about my current wifi card(beyond it being single-channel). It has pretty much perfect connectivity.
With my old router(Asus RT-N12) I maxed out at ~ 100kb/s on wifi with it and thought it was my wireless card, but I upgraded to a TP-Link WDR3600 and can get ~45 mbps on the other side of my house from my router(I get 120 mbps on ethernet.) I never have issues on campus with wifi either.
FWIW, the lspci output of my wifi card. I plan on opening my laptop up soon to put in a SSD if anyone wants me to take a picture of the actual information on the card itself.
Network controller: Intel Corporation Wireless 7260 (rev 6b)
Subsystem: Intel Corporation Wireless-N 7260
I'm using Linux(3.17.3 kernel + 7260.9 ucode for iwlwifi). On Linux make sure you're using the latest microcode for the module/latest kernel, on windows try updating your drivers(the newest one seems to be from the 19th this month.)

Glad to hear you have no problems.
But most of us here are less lucky ...
We don't need any new pictures, as all pictures are in this topic already:
We are just waiting for Lenovo to confirm the availibility of the 20200617 combo card, a specific Yoga 2 13 version of the Intel 7260AC that deals with the higher SAR values due to the positioning of the wifi antennas in the Yoga 2 13.

The latest released drivers from the Lenovo support site (Kona) are 22.214.171.124
They should be dated 2014-05-26.
Resuming several posts in different topics, wifi problems can be caused by (short recap):
After Lenovo introduced a special 20200617 version of the 7260AC called SAR I realized that the position of the antennas might cause more FCC radiation issues as they are closer to the user while typing. This is different from e.g. de Yoga2pro.
Reducing the transmission power in firmware or drivers or choosing less performing cards reduces the liability for Lenovo, but also seems to destroy our range ..
