I got a 8mbit connection but i only get around 7.35 due to my crap snr. Ive tried the ringwire trick but no luck..Before when i was on 8mbit my snr was 24 or so. I have good line attenuation of 25up 16down. My SNR now is 8db. I don't have a test socket, its an old master socket. What can i do to improve my snr?
