Wifi technical problem

have a herobook laptop with pre-installed windows 10 which I bought from wish.com about 2 months ago, and from day 1, my internet connection is not stable…. i.e. my wifi sometimes finds the network and I can connect onto the internet and many times it does not.
I tried auto windows troubleshooting, uninstall and re-install network, resetting, restarting, but not fixed….
I usually shut it down multiple times and then it may work.
It is very frustrating…
Please advise how to repair.

same problem, bought on wish too…

Reinstall the WiFi driver:
