Hello, i would like some advice on what i can do to resolve a speed issue i am experiencing on my Orcon ADSL2 connection.

The situation i have is, is that the connection speed degrads as i use it (Rapidly) until it stops, sometimes there just isnt any bandwiidth to open a simple webpage such as the Google homepage.

Here are some rough stats from memory: (posting from a different location)

ADSL2 Interleaved profile: 50-200kbs
ADSL2 Non-interleaved profile: 5mbs - 3mbs (this degrads with use until no data is being received)

ADSL1 Interleaved profile: 6.9mbs - connection is very spikey and often just stops for a minute or two.

I purely use this line for gaming and browsing, I need the line to handle both - right now i cant even open the google homepage for example. (this is a common occurance unfortunatly)

Last weekend when i asked for an engineer to check out the line, it suddenly jumped to 14.9mbs in ADSL2 mode, but this lasted 2-3 min's and would drop to 100-200kbs and shortly after that become unusable.

I can provide further details about hardware and line connection - from memory the line stats are fairly clean, no CRC errors, noise is fairly low, we are reasonably close to the exchange i believe (Modem synchs at 17mbs i think)



Here is a breif run down of some of the calls i have made to Orcon and results, i have left out a lot of the follow up calls to verify a procedure has worked or changed anything.



Called Orcon, was advised to run isolation test, and submit speed tests and tracerouts.
--Tracerouts were the same at 200kbs and 4.5mbs
--Speedtests were fine while working but when the connection was poor the test file would rarely finish
--We were restarting the modem every time we want to use the internet

Called Orcon and we had our profile changed to the non-interleaving profile
--Speed increased but line was unstable
--Speed degraded after use, 5x speed tests in a row would take the modem down to unusable speeds (i.e. cannot open google homepage)
--Cannot run speed tests the majority of the time, when i can i am thankfull i can use the internet.
--Have to restart modem every time we want to use it, clocked up 15 restarts one saturday (more time spent restarting than useing)

Called Orcon and arranged to have a test modem sent out incase it is our hardware.
--We received a letter and a bag to return the device to.
--A week later we still havent recived the modem, and it appears no one is going to send one either.

Called Orcon and arranged for an engineer to run some tests
--Over the weekend our speed increased from 4mbs in ADSL1 to 6mbs, the connection was stable but to spikey that browsing was unreliable and online gaming impossible.
--I ask to be put on the ADSL2 profile - it jumps to 14.9mbs but degrads the second you try and browse, online games last ten mins or so until the connection speed is low enough that your session is removed, five speed tests in a row take it from 14mbs to 200kbs,
--We have to restart the modem every 10 mins if we want to web browse.
--1/3 of the week there is no bandwiidth available at all
--I contact orcon again and find out the engineer will not come out until we provide him with further information, when asked what this informtion was, i was given the answer "speedtests and issolation tests"


Pretty much this is my last attempt before moving, the whole process of moving to Orcon feels like a big mistake and rip-off, like the "holiday" promotional that we did not recieve when signing up, i wonder how many other people did not recieve it?

At the end of the day, all i want is an internet connection which Orcon are unable to provide, if it can be fixed i am happy with that, if not then i need to look for another service provider.

Maybe i am asking the wrong questions, Is there anything i can do to help fix this?

Hi Acenzed,

More than happy to help you. Can you DM me your username and I will see what happened to that replacement modem for a start.

I will also look into what the team has done and see what other options we have.

Sounds like noise on your line to me. This sort of behaviour occurrs when there's static or you're getting some sort of signal interference form somewhere. Sounds like Orcon are going to sort you out, be interested to see the final result.

I am agree with uktuatara. Sounds like the line is retraining down due to interference.

Have you asked the helpdesk to perform a line test?

I was just passing home and poped in to make a few phone calls, check the router - I did talk to Warren and have a one port Router being sent out.

Just checking what information is available to me - would the following be a measurement of noise on the line?

Noise:
6db up, 16fb down

The following are all zero:
Fast Path FEC correction
Interleaved Pat FEC correction
Fast Path CRC Error
nterleaved Path CRC error
Loss of Signal Defect
Fast Path HEC error
Interleaved Path HEC error

Speed:
Up Stream Actual Data Rate - 1020 kbps
Down Stream Actual Data Rate - 18363 kbps

Recieved Cells - 22992
Transmitted Cells - 35457

The following speed test was just taken at 11:49, i will run another when i get home tonigt.

This is actually the fastest i have seen it go,





I have no idea what is going on, our connection has been dreadfull ever since we had it connected (ok, the first 2-3 weeks were good, then it went downhill, and then recently further downhill)

I just dont know what to say, 15.78 is the highest i've now hit on a speedtest. I'll try again tonight, if it stays stable above 5mbs and doesnt fluctute wildly i will be happy.

So, services appear to grind to a halt at 17:00 - which looks like major oversubscribing.

Restarted the modem, made no difference.

Took some speedtests and while posting i lost the connection, luckily i had one left in the buffer.



What is odd, is that straight after the looseing the connection, i reconnect and have the following speeds:

Sounds very much like a line fault to me. Try the new modem you are being sent. If no luck then check the line checked out.

As far as i can tell,

Quiet times (during the day for example) are fast.

Prime times (the evening when people get home from work and even worse, weekends) it is extreemly slow. (almost a 10mbs drop in speed)

Data down can litterly stop at any time during the day.

International tests show extreemly low results also. (many under 1mbs at all times of the day)

I am also extreemly close to the cabinet and the exchange is not too far away.



I am just wondering what indicates a line fault/noise - i had a line test ran yesterday and i was told it was fine. (By Orcon)

And the router is displaying 6db for the downstream.

I am no expert, that is why i am asking for help, i am just curious what indicates line noise.

Are you connecting via WiFi to your router?

PC connets straight to the Router.

I even turned the whole wi-fi portion of the router off incase there was somone trying to leach some bandwidth, with it on or off it makes no difference. (even then i had a mac address filtering list setup and a strong password for the passphrase, dhcp was turned off at one point and only recently turned back while i was testing different hardware to make sure it wasnt the machine)

I have disconnected everything from the router, tried it on both computers and my work laptop, moved the xobx from it's issolated spot in the front room and stuck it straight on the back of the router and even used the itouch.

Doesnt make a different - connection still drops out.


However i am still waiting for an engineer to look at this issue, as far as i can tell Orcon are not doing anything about this unless i constantly complain and then only as long as i am on the phone.

Definetly get the line checked out. Orcon will need to authorise that though.

Ask to get the line checked out. If you are getting disconnected lots it would be due to line noise.

I have they said it was fine.
I posted the stats on the line - if you scroll up you can read it.

Quote: Ask to get the line checked out. If you are getting disconnected lots it would be due to line noise.

I did, they said it was fine
I posted the stats on the noise, the line isnt disconnecting but rather no data is being transmited down to me and i have to power the router off to re-establish a connection.

As far as i can see it's fine.

What is the cause for:
1. Internation bandwidth being under 1mbs while nz traffic is at 15mbs
2. All data down stops
3. Internet unuseable at peak times

The test modem arrived today, made zero differece, it actually connects for less than our current ADSL2 router, while the same data issues still persist.

I cannot get through on the orcon number, but i assume an engineer still has not been sent out?

Maybe i should be talking about a refund on my monthly bill, or charging me what i can use - which is almost nothing since our connection is constantly unavailable!

Assuming you haven't managed to get thss sorted already, Try locking your modem to only use ADSL2+ , ie not Auto. I suspect it *could* be unnecessarily re-training onto the other modulations.

It's always tough to take but its unlikely that its the direct fault of Orcon as all their users would be having the same issue as you.

If you're really confident that the issues is not on your end then i guess you could request a technician but I have a feeling that will cost an awful lot if they cannot replicate the issue with their equipment.

WELL check the other thread. This guy isn't alone by any means.

Our connection is fine during certain periods and at others it's getting unusable.

The modem stays connected during this time.

No wireless link to the process.

No other factors (for e.g. outgoing traffic/zombie situation) come into it (we don't run Windows, but have checked using a firewall anyway).

I suspect that like our issue, it's not the guy's line - it's Orcon.
