I recently bought a Yoga 730-15IKB and its giving me a lot of hell with wifi. It keeps disconnecting from wifi. Any suggestions to solve this problem?

First, see if it happens somewhere else, like a public WiFi hotspot or at work. If not, you may need to upgrade/update your router as a lot of older routers or routers with outdated firmware have fits with Qualcomm's and Windows 10's' newer power-saving schemes.
Second, see if it happens within a foot or two from your router. If you have extenders, unplug those for this test. Don't proceed until you've tried these two steps.
If the above tests fail:
Set your Roaming Agressiveness to 3 or below
Force your computer to only connect at 5Ghz. You may have to set a different SSID for your router to accomplish this.
Turn off power-saving:
Set the WiFi card to "maximum performance" on battery and plugged in.
With my Qualcomm WiFI laptops, I had to update the router, force 5Ghz and turn off power saving. All runs fine, now. And if it doesn't, a reboot of the router always fixes it.

SO, I tried all the above and I am still facing the same problem. I used my laptop at work and for the first hour it was great but after that it kept disconnecting from wifi. I changed the settings as suggested and that too did not work. I just read online and they seem to be suggesting to replace my wifi card to a generic intel card. What would you recommend I try next?

How much time do you want to put in? Easiest thnig to do: Swap in an Intel WiFi card. It's not that the card is better, but you're starting over w/r/t drivers and Windows configurations. More difficult: Dig into the error messages in Event Viewer > System. If you see a lot of DCOM errors or WLAN warnings, that's possibly where the problem lies. Go to add/remove programs and look for a Qualcomm installer program. If it's there, remove it. On my 910, that program collided with a Windows update and I was forever fixing registry keys.

try rolling back the wifi driver to the last version.
I did that with my lenovo 730 13 inch and the wifi improved somewhat. Still disconnects on ocassions, but not as frequently.
ultimately, if you wish to resolve this issue permanetly, a wifi card replacement is probably needed. the disconnections are caused by the realtek wifi card or its driver.
