Hi,

So I'm having an issue where about a week ago my speed completely dropped out for a day or two and then recovered.

Since then my ping has been sitting at about 60-70 to Auckland when it would normally be about 25. Same goes for Australia (Sydney) showing a ping of around 90 when it would normally be at about 60. I haven't experienced any latency spikes while playing games either, my ping is just......higher. 

I have contacted Orcon via email and have provided ping and trace route tests, they now want me to do an isolation test over the phone with them. *sigh*

So, does anyone have an idea why my speed would be back to normal and not my ping?

Thanks.

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

 



 

If you are posting regarding DSL speeds please check that

 



 

- you have reset your modem and router

 


 

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

 

- you are not being throttled by your ISP due to going over the monthly cap

 


 

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

 


 

- you read this topic and follow the instructions there.

 



 

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

 



 

- Your ISP and plan

 


 

- Type of connection (ADSL, ADSL2, VDSL)

 


 

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

 


 

- Your general location (or street)

 


 

- If you are rural or urban

 


 

- If you know your connection is to an exchange, cabinet or conklin

 


 

- If your connection is to a ULL or wholesale service

 


 

- If you have done an isolation test as per the link above

 



 

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

 



 

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

 



 

I recommend you read these two blog posts:

 



 

- Is your premises phone wiring impacting your broadband performance? (very technical)

 


 

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

why not? its what orcon what you to do to further the fault finding

also go through what Peter reader has asked in the post after your first one

Do the isolation test.

Ild also ask if your dsl profile was possibly changed to a higher interleaving value to help with stability.


hard to comment on much else without the details peterreader asks for.

I cant seem to figure out how to edit my original post, therefore ill add my details here as per PeterReaders instructions.

We're on an ADSL connection, in an urban area.

I believe we're on a ULL connection to an exchange, im not 100% sure.

and here are the stats of todays isolation test.

Router: Netgear DGN2200v3

Extension cable + Filter:

ADSL Link             Downstream      Upstream

Sync Rate             6959 Mbps        980 Mbps
Line Attenuation     34.0 dB            21.3 dB
Noise Margin          9.4 dB              9.0 dB

With Filter:

ADSL Link            Downstream      Upstream

Sync Rate            6996 Mbps        980 Mbps
Line Attenuation     33.5 dB            21.2 dB
Noise Margin          9.4 dB             8.9 dB

Without Filter:

ADSL Link             Downstream    Upstream

Sync Rate             7150 Mbps      968 Mbps
Line Attenuation       34.0 db        21.4 dB
Noise Margin            9.4 dB          8.9 dB

Thanks.

Using Ping is a way of measuring latency to a given point, so either your latency has increased, or it hasn't.

Well, you have contacted them for help, so it's not unreasonable for them to ask you to do some basic fault finding to establish if the issue is at their end or your end. How about you post those traceroutes - they'll probably be the most helpful in pinpointing the issue. A couple to Orcon's core network, and a couple further afield should help.

Your approx 9dB noise margin indicates you are on Orcon's ULL gear, but the 34dB attenuation means a reasonably long line (physically). Not so common any more, but when the cabintisation project was in full swing, you could get an issue called midspan injection - do you know if a new Chorus cabinet has been installed recently (about the time when everything dropped for a day or 2)?

The 64ms min latency to the first hop seems pretty high for ADSL though - does your modem DSL stats page report FEC or other errors?

No clue if there's been a cabinet installed recently, as for the router, I can see no errors being reported.

I have just received an email from Orcon stating they cant see anything wrong with the speed or latency for my connection.

So, the speed I'm getting at the moment is the same as before my connection dropped out, but the ping is higher, for no apparent reason. I guess I'm left with living with it and waiting to see if it recovers by itself.

Flick me a private message with your address and I can check if there is a cabinet in the way.

Edit: You shouldn't have an issue with midspan injection as your area is connected straight to the exchange (STK - on the main road). The sync speed is pretty low for your distance (around 1km) so could benefit from getting a master filter installed.
