Yoga 2 Pro wifi is sporadic and slow

Hello,

My wifi has been slow and sporadic.  I have updated the wifi drivers on the Intel and Lenovo side, I have disabled the Intel Smart Connect Technology, I have restarted my computer several times, performed an anti-viral scan, and unchecked the "allow my computer to shut off wifi to save power" thing all to no avail.  My signal looks choppy.  My router is 12Mbps and I, at best, can get spikes up to 1Mbps, but usually my laptop hovers around 100kbps (see picture).  For some background, it came with Windows 8.1 and the wifi worked lovely and then for some stupid reason I downgraded to Windows 10.

 

Does anyone know of a fix to this?

Hi Shashi,

I did all of that before I posted and I still have the problem.

I just installed the latest drivers per your instructions and I still have the same problem. My wifi still sporadic and has low throughput.

Hi Okeke,

Latest Intel versions works with Windows 10 (Anniversary & Creators Update) smoothly.
I suspect that your Router could be configured to a conflicted channel. Possibly your Yoga 2 Pro came with Intel Single Band 7260 N that only handle 2.4 GHz networks, not the Intel Dual Band 7260 N (or AC) model that also support 5Ghz.
It's a very commom issue and I recomend to scan you network with WiFi Commander: 3D Analyze & Monitor (FREE Trial) and try to reconfigure your router with a new FREE CHANNEL.

Let me know if it solved your problem now.

How would I check to see if it's dual or single band?

And I'm not sure if the issue lies with the router. I have this issue at work and at home.

1) 'Win Key' + 'X'

2) Device Manager

3) Network Adapters \ Intel (Single or Dual) Band Wireless (N or AC) 7260
And IF you would like to double check your driver version, right clik it 'Properties' \ 'Driver'

Thanks. I also checked via the command prompt and the device properties. It's 802.11 bgn and only 2.4 GHz is available.

But what I don't understand is why it went from working well to not working properly. The wifi router has not changed so it has to be the adapter.

Routers by default has the channel configured in automatic. Channel may have changed!
As a last suggestion is to check if you're using the latest version of BIOS 76CN43WW in your Yoga 2 Pro.
