If you guys aware or it is just me, my snr in 8mbps cukup-cukup makan between 15 and 18 which previously I am getting more than 28 in 4mbps. Is it normal more port been opened snr will drop? however I don't have any issues with connection.

The SNR Margin is the difference between the actual SNR and the SNR required to run at a given speed. For example, if you need 20dB of SNR to run at 512Kbps, and the actual line SNR is 45dB, then the SNR Margin is 25dB. 

The main reason why SNR margins fall as the line speed increases is that the required SNR increases. For example, if increasing the speed from 512Kbps to 2MBps raises the required SNR from 20db to 30dB then the margin left will fall from 25dB to 15dB (as 45dB-30dB = 15dB).

What is SNR and how does one check it?

my area still no 8mbps and no unifi
