Hello, I just installed EndeavourOS and am now struggling with a weak WiFi signal strength.
I use the TL-WN722N V2 WiFi Adapter
What could the reasons for the weak signal be?
And how do I find / install the right driver for the adapter?
Please post:

Are you certain that this adapter is capable of a better signal strength?
Which driver did you install for this?
There are three options in the AUR, each tracking a different version of the driver:
aur/8188eu-dkms-git 5.2.2.4.r794.53ed527-1 (+4 0.00)
Standalone driver for Realtek RTL8188EUS (RTL8188EUS, RTL8188ETV) WLAN
aur/8188eu-aircrack-dkms-git 5.3.9.r145.6146193-1 (+5 0.62)
Realtek RTL8188EUS and RTL8188ETV Wi-Fi driver with monitor mode & frame injection support
aur/8188eu-dkms v4.3.0.8_13968-16 (+24 0.01)
Driver for Realtek RTL8188EUS (RTL8188EUS, RTL8188ETV) WLAN
Therefore, you could try a different driver version to the one you installed and see if it’s any better.

Hi,
I wanted to mention something about Gnome. I noticed recently that the signal strength indicator does not seem to be updating the signal strength accurately and maybe giving a false impression.
Perhaps if your use Endeavour and another operating system (e.g. Windows), you can do a speed test to see the performance of your network to see if it changes with the driver you are currently using?
