Guys, I've got this. Had the exact same problems (I do every single time I install Garuda) and because your system is so damn similar to my own machine (Lenovo Ideapad 14ADA015) I'm going to tell you what I had to do.
I had to get my network adapter to stop falling asleep. And from looking at your own card model and how similar your system is to mine I think you've got the same problem.
If I'm right then this is what you can do -
First, you need to get ahold of yay:
#1. sudo pacman -S yay
Then you need to get the following:
yay -S linux-firmware-git sparrow-wifi-git -y
#3. You're now going to apply the following changes to your settings:
Under the Garuda Welcome Launcher click on 'Advanced Network Settings' and make sure that your WiFi isn't set to sleep.
Then, look for your system settings and load that.
Under the Connection option check your Wifi settings and make sure your network isn't set to the 'metered' option. Make sure your system can re-connect if there's any interruption, etc.
Then, under 'Power Savings' you have to have it set to where your PC won't sleep and that your WiFi will always be on.
The settings for that tidbit on WiFi are at the bottom of the power savings settings for your laptop when it is on AC Power / plugged in / unplugged / at low levels (or something like that.
You'll have three tabs, and at the bottom of each you'll see options to change the option from 'leave unchanged' to 'always on'.
There should be (in the very same settings page) a section after that where you can define special behavior. You'll want to make sure your system is set to never go to sleep or to shut down. It is the second option.
I had to take notes on this and it took me several days to get my system working so try these and tell me if it works. Use the Sparrow Wifi tool (you can find it under your applications menu after downloading it) to check your signal.
Tell me if you need more help.
