I am the owner of a brand new Lenovo Yoga 720, 13" screen, and the internet is pretty slow over wifi. I am getting download speeds 2x or 3x higher on my iPhone and on my wife's Macbook Air, and not sure why that would be the case as all devices are connected to the same wifi network.
Anyway, any help would be much appreciated from the community. Thank you!

Make sure to go to the website and update the drivers, even though your system is new, it may have been in the channel for a while, and the latest driver was just released on 5/17/2017.
If you are running Windows 10 (Creators Edition) there are also some known issues that Microsoft is working on. I used the work around below found on Microsoft TechNet site and it improved my WiFi speed back to close to what it was before the Creators Edition update. Microsoft considers this an "emerging issue" I suspect that Microsoft may be releasing an update to address this soon, to if you are not comfortable typing in the commands below, you might wait unilt the next update.

Note: My WiFi interface was just called Wi-Fi, but yours may be different
Command Examples assuming your adapter is also listed as Wi-Fi
Note: You can restore the defaults by typing the following.

They change the value of the Maximum Transmission Unit (MSU) from the default of 1500 to 1400 and the second command disables Receive Segement Coalescing (RSC) on the WiFi Adapter. RSC is really not needed on a workstation
Microsoft released some updates for Windows 10 today, one of them being KB4022405 which addressed an issue with the Windows firewall, and applying that update seemed to fix the slow WiFi on my system without those changes to the MTU and RSC applied, so you might want to run Windows Update and see if that fixes your issue too. My speed is still about 5Mbps slower than on my phone and tablet on average, but still acceptable.

I just bought one yoga 13 from best buy, i have same problem. I cannot remote access my compamy computer while my old Dell computer can do it under same wifi and same location.
I found the website opening is pretty slow with yoga. The response is much delayed.

I have a Yoga 720 15" with an Intel dual band wireless AC 8265 card for Windows 10 64-bit. Nothing worked (none of the above steps or calling support as Lenovo doesn't have this as the latest driver on their website) until I downloaded the latest wireless card package file from Intel (don't install at this point), uninstalled my wireless card from device manager, removed all temp files, ran the latest driver package. Voila, it is back to working just fine. Latest package as of today is: 126.96.36.199

You are lucky, I did the same steps as you but the speed test shows it is slower then my iphone SE and Lenovo X1 by half the speed... Seriously Lenovo, can't you get something as simple as wifi to work???
