nighthawk R6120 Tx and Rx

Dear Netgear forum member,

my internet is slow, and i suspect it could be due to traffic congestion.

Please see attached showing Tx and Rx

I have no idea what is the meaning of these values and how to intepret the data whether there is any traffic congestion that leading to slow performance of my internet speed.

Thanks for your advice, and please let me know whether these values are OK.
