i think your line is perfect!!the lagging and delay problem is caused by tmnut

maybe your modem problem.same case with my friend's problem.he had very good margin but still always dc,but after i help him updated to newest firmware,problem is solved

near exchange will get higher snr margin?

my snr margin is only 5db.but dint dc at all........so weird huh

ask telekom come to change cable need to pay them?i stay at apartment and i am using original phone port inside the house.my snr margin is very low and i suspect this port's cable already not good (almost 20 years).so can i just pull a cable from riser to my house?will this solve the problem?

if snr margin is low and ask Telekom come to change the cable,will they charge us any fee?

i am living in apartment.i saw a telephone box outside my block.all the line are patch from there into our unit.is it they are going to change somethings over there or on the other site?

i thought SNR margin low is causing by physical line problem example old wire and copper etc?
