Despite my uplink always being 832Kbps with MaxPremium, I've still never 
had any upload faster[1] than when I only had a uplink of 448Kbps with 
Max, I gave up trying to convince the support staff via "My Questions" 
that something must be wrong :-(

link from a transit provider who peers directly with PlusNet.

What are your router stats? (Upstream SNR/Attenuation etc.)

I'm on max premium and there have been times when my upstream has 
halved. AFAIK, it's rate adaptive in the same fashion that your 
downstream speed is.

Having said that, BT's systems are reporting your upstream speed as 
832kbps so I see little reason why you wouldn't get this kind of throughput.

What kind of results are you getting from http://mybroadbandspeed.co.uk

My downstream link speed varies by +/- 200Kbps whenever it reconnects, 
my upstream always used to be 448Kbps when I was on Max and is always 
832Kbps now that I'm on MaxPremium, unfortuantely it appears that 
"something" is throttling my uplink speed so I cannot use all the 
bandwidth available

Down 1.897Mbps (237kB/s)
Up 342kbps (42.8kB/s)

Which is is very typical of the range of speeds I get.

Thanks for looking again. Since you're also on premium, out of interest 
what sort of numbers do you get?

I've got my hands on a cisco 837 ADSL router which I will give a try, 
just to see if it could be my router causing the problem.

Well, well, well ... similar connection speeds, but much better throughput!

http://www.mybroadbandspeed.co.uk/results/00807796.png

1.898Mbps (237kB/s) DOWN
710kbps (88.8kB/s) UP

I wonder if it can "hang on" to sync without daily re-connects like the 
other router...

Interesting that your upload's so much higher with the Cisco. I wonder 
if the MTU setting on your old router could be to blame? Here are my 
current line stats:

Statistics 	 Downstream 	Upstream 	
Line Rate 	 2272 Kbps 	832 Kbps 	
Noise Margin 	 12.4 dB 	10.0 dB 	
Line Attenuation 43.0 dB 	25.0 dB

My sync used to hit about 4500Kbps when I was first provisioned on Max 
(with 3.5Mbps-4Mbps throughput). Since then though I've settled for 
stability over speed. My line's capable of more, however I can't justify 
the time it would take for me to re-evaluate the situation with my 
internal wiring etc.

Here's my speedtest results:

After further investigation, I noticed I'd configured packet shaping on 
the old router, and given it a maximum upload speed of 448kbps.
