System and Network configuration • Packet loss and super slow network in debian 12 KDE Plasma

$

Hi, I had recently switched to debian and installed debian 12 with kde plasma, I had not installed with the installer but rather the kde-plasma-desktop package, the install did not give any errors but when I tried to connect to the internet it just did not want to detect any nearby networks nor connect to them, it was detecting my adapter but still not using it, nmcli device show had shown that it is unmanaged or something, I installed rfkill by manually connecting and doing some tweaks with ChatGPT, because of the AI, I was finally able to connect to my nearby networks through the applet, but I had very slow internet.

The network speed is about 100-200kbps with wifi and usb tethering, I am using the appropriate mtu that was identified in windows which was 1372, I set it on the device and in the settings of the connection itself. But still I had about the same speed, When I checked my system with speedtest-cli it showed a max speed of 1Mb/s download and the same for upload, which is ridiculous! My system used to have 5MB/s of internet speed but now it is only 100-200KB/s?

Also when I checked with the ping command

Code:

ping -M do -s 1344 8.8.8.8
It just showed that there is substantial packet loss, before when I used to use xfce, it used to be 0% packet loss.

Also I am using the best mirror in case you are wondering, I used nala to find the mirror and set the #1 mirror.
