    Weird SNR and Attenuation, How Do I know if it's ok to upgrade to VDSL?

    After reading the sticky on SNR AND Attenuation, I compared the levels to my line and it goes against the logic of SNR and Attenuation, I live around 450m from exchange and my line runs perfectly as far as I know, I can play games without drops and I download at full speed. The...

    SNR and Attenuation change daily. What is the cause?

    My (previously) 10Mbps download, 1Mbps upload Adsl line was syncing without a hitch with 27 noise margin on down and 20 on up and attenuation at about 10db each. Then my line began to drop to 6Mbps,7Mbps,1Mbps on an almost hourly basis and I was okay to deal with that until this week where it...

    ADSL Router Woes

    Hi All, Until recently we had a netgear DG834 router which has been slowly giving up the ghost on us. Losing it's settings, disconnecting randomly, dropping wifi connections until being rebooted etc. We tried another (same model and it was just as advanced in years with as many issues.) I...

    How do you improve SNR Margin?

    I'm currently on 10mbps. My line stats show that the attenuation is acceptable, but the SNR Margin is terrible. My upstream SNR Margin sometimes drops below 6.5dB and I have on occasion had disconnects. The problem is that my RedAfrica account doesn't allow concurrent connections, and sometimes...
