Topic # 139466 10-Feb-2014 14:34 Send private message

So finally made the switch to VDSL after waiting months for Orcon to offer it.

The Chorus guy came over this morning and did his little piece and everything was up and running, I then had to wait a while for Orcon to do the rest but finally have working internet and phone...

The question I have is, my download and upload rates seem very low (even lower than my previous ADSL2+ connection) and I know I am under 600meters from the exchange.. I used to get 19Mbits down on ADSL.




Any suggestions on what I should be following up on.. I know DLM is still doing its thing... but really I don't think I should see speeds this slow... could the wiring changes done by Chorus be the problem... the jack point is right next to where the line comes into the house and the guy simple used some twisted pair cables between them (you know the ones inside an Ethernet cable)....

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?

Questions:
1. What were your ADSL stats before the "upgrade" - attenuation, SNR, line speeds?
2. Did the Chorus tech install a VDSL master filter?
3. Are POTS phones on the same circuit, or do you just have a single jackpoint in the house?

1. Can't remember what they were sorry but I know the line speed was easily 19000Kbps and several years ago was around 23000Kbps
2. He changed the existing jack point to a RJ45 point... and did something with the filter (not sure if he replaced it)
3. There are no POTS devices plugged into the line... Alarm is monitored via GPRS and phone is now plugged into Genius modem

Right, cheers for the username. So I have just gotten off the phone with Chorus faults, as your provisioning order hasn't yet completed, we're not able to get any line statistics as it hasn't polled through, what I can tell you though is that from a pre-qualification done off of your address you look to be able to get around 17.8mb down/7.8mb up. You said you were getting around 19mb down previously on ADSL2? Do you have those line stats? According to the tools I have available at the minute (more will become available when the prov order closes) you should only be able to get 14.8mb down/ 1.2mb up - on ADSL.

Really need the previous ADSL line stats. Also we need to wait for the DLM to do its thing, in that time the prov orders will close, poll the information to the other tools we have available to us, How are you sure you're 600m away? From an attenuation calculator, its telling me you're about 1.5km away so there are a few things wrong here. If that is the case you shouldn't be on VDSL unless the upload is really important to you. I'm typing all this while on the phone with the technician by the way.
The Chorus tech on the phone performed a trace of the cable and confirmed you're 1.5km from the exchange. In short, you need to let the prov teams at Orcon (through the appropriate channels) know whether you want to stay on VDSL, or roll back to ADSL.

Edit - clarification/spelling

21db attenuation, you shouldnt have actually been allowed to get vdsl at all.

21db, ild expecct you were about an 16~19 on adsl.


DLM is still settling in however looking at your stats.

Hmm not sure how I would go about getting the old stats as the port at the exchange was switched over etc.


I did find this old Speedtest image I saved when I moved to ADSL2+


Pretty sure the attenuation is far to high.... I may look if I can shield the wires between the filter and the jack he put in and see if that improves it.....

Ok thats curious, yeah like @hio77 said you shouldn't be able to get it with that attenuation, my recommendation, wait for the DLM to settle.
See what that settles at, if you're happy with it, albeit slower than you were on ADSL, sweet, enjoy your upload because that will always be better. If not, migrate back to ADSL.
Something to note though, seeing as you likely have moved to a different cabinet or exchange, there is no chance you will get your old port back should you roll back. So you might not get that same speed back on ADSL.

Sorry to be the bearer of bad news.

unfortunately, not quite the stats that are being looked for.

i would ask if thats maybe on orcons own gear though, considering the figures Flame has pulled out for your line.

chorus estimates are generally a bit of a lowball, but still seems like a large gap for adsl.


your adsl line may have simply been very clean, and given your distance the vdsl signal just wont do it.

Could the high attenuation be caused by anything other than distance (e.g. poor cabling)?

Easily. Seen time and time again.

could be very well caused by a bad installation for example.

but given the prequal (im not sure of the exact attenuation on it here, so im spitballing.) that flame has paraphrased, it is unlikely.


could do a test, with the modem at the ETP to count out house wiring however - does require a bit of technical knowhow though.

Based on Chorus map and my address I was shown in an area that should be > 20Mbps....


I'm in the darkest area (on the right hand side of Blockhouse Bay Road)...
Will have a look at the wiring as I said the wiring between the filter box and the RJ45 jack was simple a couple of twisted pair wires (no shielding or anything)...

>20Mbs, is simply a shape map, prettymuch indicating possible VDSL availability.

funny story about the maps, when i used to live on blockhouse bay road, next to the wolverton, tiverton roundabout, map said less than 5mbit.


i was actually about 500M from a cabinet, happly getting 40~ (with a badly wired line might i add.)
