Installed the Billion 8800NL this evening and all now appears fine. Long may it last.
Considering that it sync'd during the evening, it's not bad at 11,192 kbps. Should be able to squeeze a bit more out of it if I re-sync during the day.
It also seems to use a bit more of the "available download rate" than the TP-Link.
And interestingly, the Billion doesn't seem to be effected like the TP-Link was when I put the Plasma TV on (IE. Noise Margin used to take a nose dive when it was on).
Noise margin seems a bit better and more stable as well (6db). So might even have a go at some point and see if I can squeeze even more out of it with a few tweaks.
Just need to check that the firmware is the latest and if not, whether it's worth updating it.
So far a happy man.
Thanks for the info. / help folks.
PS. Looks like it's already running the latest firmware (IE. 2.50a.d13).
