Sky are being no help with this as they apparently 'don't deal with upstream speed issues'

My profile shows I should sync at 21mb and 2.5mb up and for the last 3 years it's been fine and always around that with measured speeds of around 19mb down and just over 2mb up.

Over the last few months I've been unable to sync at more than 1mb up (no change to profile) and I often struggle to get a reliable 750k up in reality.

All the upstream 'pulses' when uploading and is never a consistent speed regardless of where and what I try to send.

So far I've redone all of my internal wiring (used cat6 as I had a box at home), replaced my filtered nte5 faceplate and tried without anything else but the router plugged in. My master socket is 2m from the cable entry to the house.

The results are the same with the supplied sagem router and also my draytek 2830.

Baffles me as to why they won't deal with upstream, especially when it 'stalls' occasionally meaning no requests get out. This doesn't seem to sit with them as they are of the opinion that upstream cannot affect downstream performance...

Not really sure what to do, I've Virgin available to me but they want to drill a hole through a wall that's just had a small fortune spent on getting a damp issue sorted and a hole through would wreck the tanking etc.

Fttc seems to be a while off on my cabinet, it's one of three that haven't been done aince the rest were done around 2 years ago - some planning issues I'm told.

Open to any ideas!
 
Sky don't support a faster upstream than 1216kbps officially although DLM has trained me in at 1.3 in the past. You'll be hard pressed to find a DSL provider that supports more than 1.2Meg.

Can you post your Router stats?

Not sure what annex M is tealc sorry :\

just checked my account page on sky and they have conveniently updated it so it no longer includes the upstream expected speed, only a broad range download estimate.


Assume I'm on sky's kit in the exchange as my number doesnt work on BT lookups etc.
 
Annex M is an adaptation of ADSL2+ where they use more of the available frequencies for upload, up to 3.3Mbit. I'm not sure what effect that has on top end download though.

From your stats you are looking at near enough the max you'll see on ADSL2+ Annex A.

You might be one of those direct exchange connected people who might have to wait a while until they fit an RDSLAM outside the exchange.
 
From what I can find, which isnt easy with a non BT line (its only ever been connected to sky's kit from new), I'm either connected to a cabinet just 100yds up the road or directly to the exchange which isn't much more than half a mile away.

Perhaps I was on that annexe M and they have withdrawn it? Suppose there is little I can do given that they dont seem to advertise upload speeds anymore :\

As far as I'm aware we've never offered or used Annexe M and the fastest upstream speed I've seen on the Sky Network (and I've looked at thousands of lines) was 1.3 Meg.
 
Oh trust me i did, and before they updated the account pages it said 2.5up...

Whether that was a mistake in the exchange or not I don't know but I do know I've not imagined it for the last few years Sarah :)

Point remains that this 'new' upstream speed is unstable at best and regularly hangs/pauses and cannot deliver a consistent stream of data without pulsing at best and hanging at worst. But sky refuse to do anything as 'they don't deal with upstream issues' which is utter turd.
