I got this laptop a few days ago and have yet to get it to work stably.
first problem: wifi works fine when the laptop is plugged in, but on battery power, wifi will stop working somewhere between immediately and in ten minutes. Other laptops and devices, including my aunt's (also recent, also Windows 10) Lenovo Flex 14, on the same wifi network have no issues.
When it loses the connection, it usually still shows full bars and says it is connected, but the Internet will not work. Sometimes it will give the yellow triangle. If I run the windows network diagnostic troubleshooter, it will always give a "the default gateway is not available" error, which it will say it fixed, and sometimes also a "the connection between your access point, router, or cable modem and the Internet is broken" error, which it merely shows as detected. Running the troubleshooter will fix the problem for a minute or so before it recurs again
, or I plug in the machine and disconnect/reconnect the wifi. The connection will not come back unless I intervene [edit: run the troubleshooter AND plug it in; reconnecting the wifi alone won't work].
I have tried so many different solutions; nothing has helped. Some things I've tried:
Additionally, now I have the inexplicable new problem where with the AC adapter plugged in, the laptop will just stay at whatever battery % it was at and give me a "plugged in, not charging" message. Lenovo vantage's battery conservation mode is turned off, so it's not that. [edit: figured it out, not charging over 95% is a "feature"]
What can I do to fix
these this? I'm out of ideas and I'm tired.

I appreciate the reply, Moe, and I tried the one or two solutions listed there that I hadn't already. None of those solutions fixed the problem.
The problem only happens on battery power, which is why I believe the problem is something beyond general wifi issues.
I did solve the "plugged in, not charging" problem on my own, though-- apparently not charging beyond 95% is supposed to be a feature, not a bug.

The only solutions I can find on this forum that actually worked for people were to send the machine back to Lenovo to install a different network card. Is this the necessary solution? I do, in fact, have the dreaded Realtek RTL8822BE card that both posts mention.

Hi hedgemaze, Thanks for trying those troubleshooting steps. We would like to confirm does your machine have a Realtek 8822BE card? If yes, try these steps.
Download this Driver:
Go to device manager
Expand network adapters
right click wifi card driver and uninstall (Click tickbox to delete driver software)
Install downloaded driver
Test if it works.
Let us know how this goes. Thanks.

Thanks, Jack. I do have that network card, but I actually solved the problem by installing this driver:
Thank you to you and Moe for attempting to help me! I'm glad this is fixed now.
