ADSL Connection Speed dropped from 6MB - 3MB with 7402

Hi there,
I have been using my trusty Netgear DG834G for a couple of years and its worked flawlessly. I have been running an 8MB ADSL connection since august with a connection speed between 5.5 - 6.5 MB. last week I decided to buy a Billion 7402GL mainly because of the QOS. After connecting the 7402 I noticed that the connection speed was lower 4.5MB so I started to tinker with the gain and DB settings. I then started to notice the connection speed dropping so I put everything back to default on the 7402. The connection speed was now 3.5MB this was Saturday. On Sunday I looked at the speed and I noticed it was at 3.1MB. So in 2 days my connection has dropped from about 6 to 3MB. This morning I decided to put my Netgear back on and that is now connecting at 4MB.

Am I right in saying that the BT side is learning and because of my messing has dropped the speed ? Is there anything I can do to get the speed back to 6MB?

My downstream is

Noise 12
Atten 24

Upstream

Noise 25
Atten 10.5

Any help would be greatly appreciated

You might have triggered a lower bras profile with your activities. However, it is odd that your sync speed has dropped so much, even when going back to the old router which previously synced much higher.

Assuming it connected at 12dB, it looks like your target SNR margin's been increased. Another 6dB would probably get you a flaky 5-6Mbps

Looks like the bras drops instantly if it detects any issue but can take days to go back up. Guess it's just setup and wait for it to go up, hopefully.

Well it was sat between 5.5-6.5 for about 2 months without issue with sustained 500K + downloads until I dropped the 7402 in.
