I suspect it may be real this variation, and is down to how the GT populates the bins and calculates the margin perhaps.

Certainly I do see connection problems if margin drops into the 1-3 area.

With a 7dB margin, then since Tiscali LLU uses a 12dB target margin, your sync speed may almost half.

So what you gain from loss of BRAS Data Rate may be lost to the higher margin

Oh and I was reading in flat mode, and missed that you were not the OP - long day, and not just this place

Thanks for that Andrew.

So, if at some point in the future I moved to Easynet/Sky (whose default, apprently, is 6db) - what *should* the effect be then ??

A minor change, maybe an extra 128Kbps but a bit more of a gain from no BRAS Data Rate

If it is ADSL2+ you get, you may get a bit more speed too.

Not from our findings Andrew.

Using other routers on the same line show very little variation on reported SNR values and usually no disconnections - we have tried vigors, d-links and a few others I can't remember, all showing a rock steady SNR value. In the case of a DG834, firmware versions 1.05.00 shows very little change in SNR, but upgrading to 2.10.10 or 3.01.25 on the same line on the same router show wildly varying SNR values.

This is not down to line conditions, its a fault in later firmware versions but we have yet to convince Netgear to investigate further. We have managed to get past 1st line support to 2nd line support in the UK but since then no word from them.

This is also affecting many people on different lines / exchanges and suppliers (BT & LLU). It appears to be more prevalent on lines > 2Mbs speeds which is probably why this was not noticed pre-Max.
