    Different attenuation/SNR values between DSLAM and Router

    Hi I have attached 2 pictures one showing stats from my router and one showing stats from the other side of the DSLAM. My router gives me very bad readings yet I am close to my exchange which makes me believe the other screenshot is correct. I need help understanding which one is right and if my...

    No ADSL Wonderboom area

    Hi all, I have been experiencing extremely unstable ADSL connectivity in the Wonderboom (Pretoria) area, and since yesterday my ADSL does not sync anymore (I believe the router has finally decided the attenuation and SNR is just too poor). I am on a supposed-to-be 10Mbps line, and although...

    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...

    Latency on ADSL Line - Eldoraigne X6

    ADSL 10Mbp/s & Packet Loss

    Hi All. Can somebody tell me if the stats below seem OK to run at 10Mbp/s. From the research I have done online (http://fremnet.net/article/216/adsl-theoretical-speed-calculator), it seems that the below Attenuation etc. is more than acceptable, but since being upgraded to 10Mbp/s I have...
