I have 2 routers at my home

- One is the "Archer AX53 v1.0" which is the main one connected to the WAN

- And the other router is a signal extender connected to the main one via an ethernet cable 

I was trying to connect to my secondary router but i noticed it always fails to connect, it wasn't doing that before

I went to check my 2 routers via the web interface, the secondary router looks fast and fine

The main tp link one however was so slow and i could not access the web interface easily

I noticed that the CPU usage is 100%, this is why it was so slow and it took to long to navigate inside the web interface

Is there a way to monitor system resource usage ?

Monitor in detail so that i know which process is causing the problem and try to troubleshoot this problem 

For instance, in my linux machine i use btop
