I've had FTTC for a few weeks now and, up to a few days ago, have been getting around 64Mb/s down and 17Mb/s up. After a few line drops in the early hours I'm now getting 64Mb/s down and only 7 or 8Mb/s up.
I've tested via uploads to a VPS and various speed testers (including BT's). I've tried direct connection of laptop to the openreach modem (using Windows PPPoE), my Billion 7800N in EWAN mode and with a friend's Vigor 2750n. The 2750n reports
Profile State UP Speed Down Speed SNR Upstream SNR Downstream
17a Showtime 8491 (Kbps) 67240 (Kbps) 127 (0.1dB) 64 (0.1dB)
Is there any reason why upstream should suddenly drop from 17 to 7 like this while downstream is unaffected? Is it something that will correct itself over time? I'm pretty sure BT aren't going to want to know as they give no upstream speed guarantees.
Thanks,
Mike
