Massive upload speed drop?

Have FTTC and have a solid 20 / 3.5 - 4. Recently (Last few days to a week) my upload speed has massively dropped to 1.3mb/s
Why is this? I tried a router reboot and it's still stuck there.

Re: Massive upload speed drop?

I was fiddling with my D-Link router the other night (mostly trying to re-set it since it had been used as an access point for three years) and noticed my upload went from 17.01Mbps (amusing number seeing as I'm a trek fan) to about 1.4Mbps after I reset it to defaults, turned out simply to be the QoS Engine was enabled (it manages the network traffic to ensure everyone gets a fair share of the bandwidth), disabling that brought the uploads back into the 17Mbps range...

Don't know if it's the issue you have but worth a look... Smiley

Re: Massive upload speed drop?

Unfortunately I haven't got the QoS enabled. Haven't changed anything in my router configs either. Thanks for the suggestion though!

Re: Massive upload speed drop?

Hi there,
@spudy12
Sorry to hear about this, I can't see or think of anything obvious that might be causing this for you.
I take it you were using a wired rather than a wireless connection when you recorded those speeds?

Re: Massive upload speed drop?

Yes always using a wired connection, nothing has changed my end.
Could it be to do with this interleaving and DLM I've been reading about?
EDIT: Also using the BT tool ( http://www.dslchecker.bt.com/ ) it says worst case I should be getting 4.3 UP?

Re: Massive upload speed drop?

A question I've asked on similar threads because it fixed a problem for me - do you have Networx installed?
My upstream slowdown coincided with a Networx installation, although I didn't twig right away.
I uninstalled it a few days ago, and upstream is back to normal.
Things that can eat up your upstream bandwidth are Trojans and the like - it's always worth checking your PC for viruses and Malware as well.

Re: Massive upload speed drop?

No not got Networx on my netwrok anywhere but thanks for the suggestion.
I run a pfsense router / firewall behind the plusnet modem and have a traffic graph so I can tell nothing else if using up the bandwidth

And yes, I have also tried plugging directly into the modem. Same speed results

Re: Massive upload speed drop?

Any reasons this has happened @plusnet?
Really quite an annoying problem.
Appears I am not the only one this is affecting either.

Re: Massive upload speed drop?

Yes I've seen quite a few people reporting this recently on the forum. Surely there must be an obvious reason for this?
There is nothing wrong with my line as far as I can tell.
I've reset the plus net modem. Even upgraded the firmware on it to the official netgear one. (I have the plusnet WNR1000v3)
Going to try to look at the stats on the openreach modem box tonight.

We've no reason to believe there's a single issue affecting multiple customers.
I'd definitely advise as the next step connecting directly to the Openreach modem so to rule out the router a being a potential cause of the problem.

Re: Massive upload speed drop?

I have been losing uplink speed for some weeks. 3 Engineer visits so far over 3 weeks, always a reset restores the speed, and then it drops away over days (clue there?). The first engineer said that there were about 470 faults showing on my socket (a Mk2 fitted when Superfast installed) and he replaced this with a mK3. After a reset, speed returned, Normally this is about 50 Down (48-52Mbps) and between 13 and 17Mbps UP. Over the next fortnight the speed deteriorated, Down to about 34Mbps, but UP to about 2.7Mbps.
I reported a fault and by the time the engineer came (last Thursday, 27th Nov 2014) my uplink speed was down to .78Mbps, slightly slower than ADSL and ADSL2 had been. He checked the line and said there faults appearing like rain on his test meter, which he showed me, and I saw being added like £1000's to our national debt. "Its interference" he stated with authority. Out came a tranny and round and about he went listing for buzzing hotspots, occasionally shaking his head. I turned off our mains isolator, the tranny more or less fell silent, but he still recorded line faults at the same sort of rate.
"We need to get a REIN guy in", he said, and rang HQ on my landline (Vodaphone doesn't work in our part of the world and BT rely upon Vodaphone for delivering test results), but the REIN guy was 60 miles away looking for interference in Sussex. He reset our connection, back came the speed, and he left. Early the next morning there was a tap on the window (bloody plumbers!) and there was the REIN guy. He checked our line, replaced the MK3 socket with another one "just in case". Disconnecting us at our socket, and at the cabinet showed not line fault seemingly. Driving the route showed no interference, he tested our cabinet connection and said he'd load it up to see if it stayed good, which it did.
With no REIN fault, his job was done, and his boss pulled him off the job, but not until he'd reset our connection and checked that service was back up to normal. He said that we'd see the speed drop off again in all likelihood, because nothing had been done that would correct a fault. He was right, because the Uplink speed is dropping by about 7-10% per day on a downward slope. PlusNet still have the job open and at time of writing have not had a report from BT about Thursday's visit (I suspect that they don't know about Friday's RIEN man "officially" without that report).
I have spoken to PlusNet today but the guy chasing BT wasn't at his desk.
So there you have it, slowing Broadband, being throttled back automatically by equipment, one has to ask why it is allowed or designed to do that and why then, a fault isn't being addressed?
After many successful months something has changed for the worst, or been changed. I can't help feeling that someone knows and is hoping that the customer doesn't. that could be PlusNet, it could, and perhaps probably is, BT. What else can one think?

Have tried multiple VDSL modems (as you can probably see by the recent disconnects on my line)
Have raised a fault with you guys (fault number: 95564707)
Also, as in other reports people have said lots of bt engineers around their area, no bt engineers round my area / cabinet
