Router somehow capping download speed

I am using a Netgear DG834v4 modem/router. It seems to be capping my download speed at 1 Mbps. Any idea why please? If I swap it for another router I can immediately get about 4 Mbps. When I swap back to the DG834, speeds are immediately limited to 1 Mbps.

is that speed as in a speed test or speed as in sync speed

Thanks., It's what I see from a speedtest and from the router stats and from Windows Task Manager ethernet figures. They all show 0.9x or a flat max of 1.0.

So what are the full stats with the Netgear

Is the 834 set to just ADSL or G.DMT?

Please give the exact sync speed from it in kbps, not Mbps.

Stats here

Sorry, what is G.DMT? Where do I look?

I did a reset of the router and entered my DSL userid/password, nothing else, so everything is default values I guess.

I forget what the menu is called, but it will be something like Internet, or Connection. It gives a list of tick-boxes with ADSL, ADSL2, ADSL2+ and so on.

G.DMT is what the first of those is often called.

It doesn't matter now we have the stats though, as your stats show you are on either ADSL2 or ADSL2+, which is what I wanted to check, and your sync is not exactly 1152kbps which might also have indicated ADSL/G.DMT.

Assuming you mean you did a Factory Reset of the router, not just a reboot, then it's inexplicable to me. The noise margin shows you have plenty of sync available, and the attenuation fits with the speed you get from others.

What is the other router? I am wondering if the "other" router has the ability to manipulate the target SNR and the Netgear isn't. With an SNR of 15 there is wiggle room on the netgear - I suspect the other router is using a different SNR target margin. Can you get stats from the other router?

The other router is a BT-branded 2Wire 2700HGV.

I'll post the stats (probably tomorrow).
