Our exchange's BT equipment, which Freeola use here, was upgraded from "Max" (ie limited to 8MB down and 0.4MB up) to ADSL2+ about a month ago, and I got the option to upgrade.
So, despite having a long 5.5km line, I did and I thought I'd share my experiences.
I'm using a Netgear DG 834 G router, running with bog standard settings and firmware.
On the old "max" service downstream sync never bettered about 2.4MBits/s giving a best throughput of 1.8MB, and upstream was of course capped at 0.4MB - a real pain!
On ADSL2+ the initial S/N margin was around 15dB, giving a sync of about 2.4MB equating to an actual throughput of about 1.8MB down / 0.5MB up, so there was little visible change over the original performance. So I thought "oh well, at least it's no worse".
However since then it has trained itself gradually down to a 6dB S/N ratio, and it now syncs at around 3.9MB down, giving an actual throughput of about 3.5MB, and the upload throughput is around 0.7MB. This has been stable for 10 days now.
In other words performance has close to doubled, despite a line length of 5.5km and an attenuation of around 63dB.
So if you have a long line with poor stats and you are wondering if ADSL2+ is worth it - perhaps it may mean buying a new router - my experience is that it definitely is.

Hi cbell and welcome to the Freeola forums!
Glad to hear your ADSL2+ upgrade went well. My olde worlde 20CN exchange hasn't even got an upgrade scheduled which is a pain!
Your sync speed is really good for that attenuation!
As some people on longer lines can lose stability it's good to hear you didn't. If your router is reporting an attenuation of 62.5 / 63db then it might even be longer as many routers use those figures as their maximum to display.
Did you see the attenuation rise when you changed to ADSL2+ ?
The higher frequency can add 2 or 3dbs.
On my line (currently showing 48db attenuation) I've found router choice can make a big difference.
Can you say what 'version' your router is as they use different chipsets? (It should say v3/v4/v5 etc. on the sticker underneath)
Apart from a better connection speed you will also benefit from more efficient IP Profile management - both higher speeds and faster recovery if the profile should get lowered!
If your line keeps running stable then the Target SNRM will drop to 3db (lowest default on ADSL2+) which will give you even more speed.
Thanks for an interesting first post! :¬)
