Have a try, mine works fine. Send it back, if you have issues.

In the US, I don't think it is easy to return a used laptop to Amazon for a refund.

At this point, I would guess there will be a Haswell update for the Yoga in the next few months. If you can wait, I would recommend waiting.

If you can't wait, I recommend buying a cheap Yoga from the Lenovo outlet. Yogas are frequently available on the outlet at substantial discounts (as of 12-June-13 there are i5/4GB/128GB models on the outlet for $549.36)

Re: yoga 13 wifi issues

I didn't have any issues with my Wi-Fi but I installed the new Wi-Fi / BlueTooth driver (version 1.04.0213 posted on June 6, 2013) to see if I was missing anything.  It broke my BT mouse and USB 3 Ethernet adapter, so I ended up rolling back both drivers to the original version.

 

From my experience Wi-Fi driver 1021.2.904.2012 works perfectly.  The new version is 1021.9.517.2013 and caused problems when I had my USB 3 Ethernet adaptor plugged in.  It kept the wireless connection connected along with the wired Ethernet connection.  When I unplugged the Ethernet adapter, the wired connection went away (as expected) but the wireless connection dropped and required me to manually refresh the connection.  When I rolled back to the original driver, the network switched between wired and wireless automatically within 2 seconds when I plugged and unplugged the Ethernet adaptor.

 

BlueTooth driver 1.3.639.3 worked fine.  When I upgraded to 1.3.644.3 (both drivers get upgraded with the Wi-Fi update) my Microsoft BT 5000 mouse started to lag big time.  If I moved the mouse quickly to the left and then to the right, the mouse pointer would take over a second to catch up.  My BT Creative D100 speakers worked fine however.  I ended up rolling back to the old driver.

 

So my advice is to stay away from the new driver update.

Re: yoga 13 wifi issues

2013-06-18, 6:37 AM

Hi all,

 

I have just added the following as a comment to Scott Booth's new review of the Yoga in Tom's Hardware.

 

I have been a Yoga owner for the past 3 months and in general I really like this hybrid though it takes some time finding out new ways of utilising and working with, especially when you are also new to the modern/metro interface but I don't find the learning curve steep and for me it's definitely an enjoyable and amusing process. Overall I have no regrets given that it is also a fantastic traditional laptop. As opposed to others I don't find any problems using Windows 8 in traditional desktop mode with mouse and all and no, I don't miss the Start button.

BUT... as a couple of contributors here have already commented, THE WI-FI / BLUETOOTH MODULE ON THE YOGA IS SERIOUSLY FLAWED. To prove that point just try to Google 'wi fi issues' and see what comes out on top!

In an otherwise interesting review I'm surprised to see that the WI-Fi section deals with only signal strength and not data transfer rates which is supposedly of more interest to the end user. Here the Yoga is challenged especially if you also use one or more Bluetooth devices (like a mouse and streaming audio). Sitting in a space with -61 to -67 dB signal and with no competing or overlapping channels you at times get transfer rates as low as 6 Mbit/s (turning off BT devices increase the speed to around 25 Mbit).

The Yoga apparently is also very choosy in which wireless router it's connected to. I have personally tried 5 different ones at home (TP-Link WDR4300, Thomson, TP-Link WR741 with Gargoyle, D-Link DIR645 and Netgear R6300), and with the Netgear R6300 I, in some cases, get the above nearly tolerable speeds, but not anything that can match my other wireless devices. I'm now contemplating purchasing the Netgear A6300 USB adapter in order to obtain reasonable and stable transfer rates although this step also contains a number of cons.

Despite subsequent driver updates Lenovo/Realtek has not managed to solve these problems. The latest update even includes some kind of USB trigger, installing itself as a running service with log file and all. For all we know it makes the mousepointer flicker every two seconds....hilarious!!!

I (and I'm sure, many others) would be really interested if Scott could elaborate more on the possibilities of utilising the empty slot for adding/changing the WiFi/BT adapter to a PCIe thingi. What would be the real options given the BIOS whitelist and all???

The new driver update (WIFi: 1021.9.0517.2013, BT: 1.3.644.3)

 

To GzyOnline:

 

I did install the new driver and as mentioned before I believe stability and transfer rates improved a bit, but I really didn't test it thoroughly because other issues developed: After reboot the driver/adapter initialises and connects but after a while (20-40 secs) I get a 'limited connection' showing on the network, as when there is network connection but no internet only here there is NO connection, not even to the router. When trying to turn off the computer, it stalls (black screen but not turning off) and I have to do a hard reboot by pressing the physical power button for 5 secs. After hard reboot, the driver will work again but after normal reboot/shutdown the scenario repeats.

 

The new bluetooth driver on the other hand solved my issues with power saving features on my Logitech M555b mouse disabling all BT Devices including audio stream to my Bose Soundlink speaker.

 

So i rolled back the WiFi driver to the beta (1021.6.118.2013) and kept the new BT driver.

 

I have of course disabled the mysterious RunSwUSB Service, which makes the mouse pointer to flicker in wait mode, but when testing the driver, I tried with the service running as well.

 

Have not really had time to do more.

After numerous issues and trying every single driver offered, I think my Yoga finally works. A technician came out and replaced the motherboard and wifi card. After he finished, he casually mentioned that when he opened the device, one of the wires to the wifi card was loose and not connected properly. That was probably the cause of many of my issues. 

 

The newest driver works well, offering the best ping rates and connection speeds. I still have occasional dropouts so I'm not tremendously impressed with the machine, but overall performance is far better than I was seeing. On battery at least. 

 

The wait mode on the pointer is odd and I will be suspending that run service as soon as I can find it. 

 

Thanks everyone here for the advice, posts, and intel. Best of luck getting these machines to work properly - frankly, I've owned Dell, HP, Compaq, VAIO (Sony) and multiple Lenovo machines and they've all had issues. At least Sony and Lenovo fix theirs.

Anyone find a solution to the "limited connection" issue?

 

1 - Connect Yoga 13 to wifi

2 - Power off / Sleep

3 - Power on

4 - Wifi connects, but shows "Limited".  No data works.

5 - Only way to get it back is to restart wifi router.

 

Seems like a weird problem.  No other device has problems on wifi (Surface RT, mobile phones, etc).

 

Driver - Realtek RTL8723A 5/17/2013, 1021.8.517.2013

Router: DLink DIR-655 WPA2 802.11n

 

Rant - Just got this Yoga from outlet.lenovo.com refurb.  I can't see how they could ship this thing in the state it arrived.  No wifi enabled (device mangager), needed to regedit Security Packages to enable remote desktop and Microsoft account.  I can see why Microsoft decided to get into hardware biz.

May have addressed Yoga 13 limited connection issue (for now - given my out of box experience, not too optimistic).
