HI chaps,

I have a vigor 2920 with 2 x 72meg Zen FTTC PPPOE inputs (via BT modems) and until recently I got a good 72/72 from each connection simultaneously

Recently it has dropped so that I get 63/50 and never above this

My Sync is a solid 79.9/18 on both lines - the green box is only around 200m away

If I go direct to the BT modem via PPPOE and make a dial-up connection I get 77/17 on zen speedtest

any idea what could be happening? I have the latest firmware 3.6.8.5 but it seems the vigor cannot cope any more

I do not have QOS enabled at all

suggestions gratefully received

it seems to be the DOS Defence option causing an issue - with DOS Defence off everything is back to normal
