Hi all.
You may have seen this post on other forums, but I'm hoping you guys will be able to offer me some help here...
Basically I'm in a new build flat, recently moved in, XILO are providing an ADSL2+ line through Cable & Wireless. The Kitz line checker says I'm about 900m from the exchange. I bought a Zoom ADSL modem and plugged it into an old DIR-615 with DD-WRT installed, full bridge. The connection at 9dB SNR margin was about 14mbps.
Using telnet I tweaked the SNR margin, and the modem reported a sync speed of 19mbps. Great thought I. But throughput is still 14mbps.
To cut a long story short I was convinced it was the modem, but I today installed a Netgear DGT834 GT with DGTeam firmware installed, and same story.
Here's the line stats from routerstats:

So guys, any ideas? I'm at a total loss! My conclusion is that C&W unbeknownst to Xilo (as they've said the link speed isn't limited) are limiting my connection to 14mbps. Is this possible/realistic?
