Slow speed Ethernet issue on Ubuntu 24.04

I recently changed my system to Ubuntu from Windows and I use my mobile and USB ethernet to connect, I used to get 500+ mbps on Windows by using USB tethering, but on Ubuntu 24.04 I am getting only 4 mbps. I am new to Ubuntu please help me solve this.

sudo lshw -C network

output:
