Linux ubuntu vs wifi

[computer1337]

Hello everyone,
I am experiencing problems with ubuntu and wifi. Basically sometimes i boot my laptop and it works, sometimes not at all, but mostly it will work at the start and after few mins it just stops working. I got the latest ubuntu i guess as i installed it a week or two ago. My laptop is: Lenovo ideapad 110-15IBR.
Model name: 80T7
Please someone help me out as im new to linux and until now my experience is awful.

This is afaik a manufacturer problem, not a Linux problem. The computer was sold with Windows os preinstalled, and the manufacturer doesn't care to make a driver to other OS (because you're supposed to buy a new computer or OS when MS tells decide that the old OS isn't supported anymore)

I see several forum where the same network is mentioned, the solution seems to be to update the kernel to newest version.

Which ubuntu/kernel version?

There were some fixes applied to the kernel in October which should be in version 4.14+
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?qt=grep&q=rtl8821ae

You can find kernel version with command:
umame -a

search google how to get latest stable 4.14 kernel if you are unsure how...
