Topic # 101381 30-Apr-2012 21:31 Send private message

OK, hope someone can help me here... I'm a new TC customer. Signed up for the $75 deal and switched over a couple of weeks ago.

I noticed my browsing was really slow for the last few days. So I started regularly doing speedtests yesterday (Sunday) and getting ~0.5Mbps down, then 5 mins later it will be ~1.2Mbps. Still pretty slow. This can be any time of day and earlier in the week I was getting ~7Mbps. Monday morning before work I managed 5-6Mbps. Right now (Mon 9:30pm) I'm getting less than 0.4Mbps. This is using speedtest.net, Telstra's and Consumer's speedtest.

I tried everything to pin-point the problem. Different PC, different router, isolation test. So I logged a fault (TC answered straight away!) and Chorus came out to check the line (again, straight away!). From the street the Chorus guy was getting 7.6mbps down. He suggested it could be internal wiring.

My wiring is a bit of a mess so I tried the first jackpoint in the house. Then I tried wired up my router straight into the wire coming into the house and still ~0.5 down.

The Chorus guy is coming back next week to check the wiring in the house, although I'm worried I'll be charged for that.

My modem stats show:

Downstream Data rate(Kbps): 7616Kb
Upstream: 832Kb
Noise Margin 20 / 13
Output power(dBm) 119 / 158
Attenuation(dB) 9 / 6

So wouldn't that suggest the wiring is fine? If my modem is reading download speed at 7618Kb how is my browsing/speedtest so slow?

I'm not connected to a cabinet. So could this be an issue at the exchange?

Thanks in advance for any help!!

Hi,

I just posted to the Youtube slow thread. It looks like a couple of threads have similar themes over the last few days.

I just thought I'd let you know my ADSL is running really slow too.

Usually it's very good, but the last couple of days have been horrible.

I just did a speedtest - 0.4 Mbps up / 1 Mbps down....sigh..

I'm in Tauranga.

Exactly the same issue with me and also in Tauranga, (in the Bethlehem area).

Service is ok during the day but evenings have been terrible.

Odd thing is that the telstraclear showed download of 14mbs, but the consumer one puts me at less than 1mbs at the moment. The Consumer test is more consistent with what I am seeing in real life.

Not sure but there also seems to be a difference between domestic and international.

I have put it down to some very heavy users in the area ... but may get TCL onto it soon.

OK, update Tues 7:30am - now 6.40Mbps download. It appears to be a peak-time problem. From reading your replies I'm not the only one experiencing this?. I'm in Auckland btw.

Yes peak time, I am at about 11mbs this morning. Been happening for the last few weeks - from about 6pm through till about 10pm, usually during the week - weekends are less of a problem.

I'm only about 300 to 400 metres from the cabinet so that should not be an issue.

7616 suggests you're connected at an ADSL profile rather than ADSL2+

I'm the same, in Palmerston North and signed up for the $75 deal too. Previously was on Vodafone with awesome speed, now it's like I've gone back 5 years. Youtube has taken forever to buffer last few nights.

that looks like a d-link 504t or similar vintage.  upgrading firmware should fix it partially, but you'll never sync as high as a broadcom that close to an exchange.  you'll probably sync around 16 megabit after firmware upgrade, or 20 megabit if you change modem.

although at the same time if download speeds are dropping a lot as well, then there may be more than one problem.

Yeah, that'd be right as I live in the middle of nowhere! Still, why am I getting such slow speeds when the modem says it can get 7.6Mbps?

(This message applies to ADSL only as i've been with TC Cable and it was fantastic) It's generally Telstra Clear tinkering with your speed due to low capacity. I've been on / off at them for almost two years about the same issues since i switched.  As soon as my contract expires i'm leaving unless mine improves permanently. Usually I report it and after much persistence it improves. Within a few months it goes back to how it was and the process starts all over again.

Yes, I too used to be on the cable when I was in Wellington and life was so good, ADSL no matter what variant is definitely the poor cousin. Roll-on UFB.

My assumption is that given TCL is effectively reselling  chorus ADSL capacity there is not much that can be done unless more capacity is commissioned at the cabinet - on the basis this is a contention issue.

Happy to be told different so that I can ask tell TCL what I want to happen.

Got a response from TCL last night, seems they are aware of the problem.

"We are presently investigating an issue with broadband speeds, especially in the evening, and it would be helpful if you could conduct a few tests for us to help evaluate connection speeds in your area."

Have asked me to run three tests morning, afternoon and evening to send to them.

The results I just sent to TelstraClear.
Details below. I have also used the consumer site speedtest data because the numbers reported by the telstraclear site bear no resemblance to the real-world performance I am getting.

time - TCL ping / down / up - Consumer down / up

7:25am - 48 / 15.36 / 0.78 - 8.89 / 0.80
7:35am - 47 / 14.76 / 0.80 - 10.69 / 0.80
7:45am - 48 / 14.30 / 0.79 - 9.29 / 0/80

2:35pm - 47 / 16.29 / 0.79 - 2.79 / 0.75
2:45pm - 47 / 14.84 / 0.78 - 2.67 / 0.80
2:55pm - 48 / 15.65 / 0.79 - 11.46 / 0.80

5:25pm - 47 / 16.29 / 0.79 - 0.61 / 0.78
5:30pm - 48 / 14.84 / 0.78 - 0.54 / 0.64
5:35pm - 48 / 15.65 / 0.79 - 0.62 / 0.65

For the last one I also used the Geekzone test and it came up with 0.82 / 0.77 so confirming the consumer results.

I can assure you that your assumptions are wildly incorrect. Cabinet capacity isn't, and never has been an issue with wholesale services. EUBA services also have no handover dimensioning at present.

As for ADSL being a poor cousin I agree - purely because ADSL has limited upstream. VDSL2 on the other hand delivers real world 50Mbps / 10Mbps today and for the vast majority of residential users in NZ UFB is still 5+ years away.

ok - happy to stand corrected.

What I am trying to work out in my mind is that this seems to be a problem with congestion given it is only a major problem in the evening - which I assume is because everyone comes home from work and onto the internet,

If congestion I presume it is either a  physical constraint somewhere in which case changing provider won't do much (but I think you are saying that it will not be a physical problem) or a problem with the TCL capacity that it is reserving, or the way it is peering etc (which may be the case given the TCL speedtest  always shows good speeds when the other tests often show very poor speeds) in which case changing provider would solve the problem.

And yes I wouldn't mind VDSL (Chorus mapping tool says I can get it) but last time I looked (which was admittedly a while ago) it was expensive (often because there seemed to be an assumption that if you were on VDSL you wanted a lot of data which is not necessarily true).
