Topic # 109950 30-Sep-2012 12:56 Send private message

Hi guys, 

Just recently bought my first house, and organised Vodafone naked broadband (as it's fairly cheap when packaged with Sky. I researched providers for months before moving in - and saw Vodafone had achieved some great results in the Truenet tests.

The house I bought was previously owned by someone fairly high up in I.T. at Telecom - and he said the speed was decent here (I assumed he would have ensured it was amazing).

However, since setting it up I've faced constant disconnections and random slowdowns. At times when it disconnects, it won't automatically reconnect (even overnight) and I need to reset the modem to regain a connection.

For example just ran Vodafone's speed test:



The latency is insane. But it's not always like that - I've run speedtests at various times and the best I've seen is 9Mbps down and 1 up and approx 29ms. 

My place is on the border of Mt Eden and Balmoral - and definitely in the 'red zone'.

There's nothing else plugged into a jack in the house aside from the modem.

I should note I'm not using the standard Vodafone modem - instead I've got a Netgear N600 to improve the range. 

There is a chance I haven't configured the modem correctly. 
Settings:
PPPoA
NAT enabled
VC multiplexing
VPI 0
VCI 100
DSL mode: auto
Transfer mode: ATM

I should also note I'm using a jackpoint in the study with the label "R-NGT TRIAL" which I assume was a trial telecom was doing at some point.

Any help with this would be much appreciated!

Also please make sure the modem has the latest software loaded if you are using a HG55A

http://forum.vodafone.co.nz/forum-19/announcement-8-23-aug-2012-new-hg556a-firmware-available/

What basic fault checking have you done?

Have you tried the HG55A modem to see if things improve?

There are so many threads on Geekzone about basic fault checking and how important it is to get the house wiring checked,

Look up coffeebaron here on Geekzone and have a chat with him

Speedtest results by themselves are pretty much meaningless.

DSL sync stats are the most important thing, as is the distance from the cabinet/exchange. You also need to establish exactly how your house is wired as far the most common cause of such issues is internal house wiring.

It's also worth remembering that a master DSL filter is essential to get the best performance unless you're running a modem off a single jackpoint.

Thanks guys,

I've already done all the basic fault checking described in the various threads. Pretty easy when It's naked broadband and modem is the only thing plugged into a jack in the whole house. Tried different filters too and that hasn't made a difference. 

I'll try switching to the free modem supplied - but as mentioned I'm pretty keen on using the Netgear N600 if possible due to the increased range / quality. 

Anyone know what the R-NGT trial is (it's on a label on top of the jack point in the study)?

Could anyone confirm if the modem has been configured correctly for Vodafone (details in my first post)?

Also - is there any way to figure out my sync stats or how far I might be from the exchange?

Cheers.

The most basic of fault checking requires performing an isolation test, ie disconnecting all wiring from the home and plugging in the modem to the demarc. Just because you have Naked DSL doesn't eliminate your internal wiring as the cause of the issue. There is no need for plug in filters on a naked connection, but master filter is still essential to deliver the best performance as it eliminates reflections from multiple jackpoints in the home.

Sync stats are visible in your modem and you'll get a rough idea of your distance from a cabinet/exchange from the Chorus SAT page.

I also assume you're doing speed tests via a wired connection? A test using wireless will also typically deliver false results.

And yes your modem is configured correctly, if it wasn't you wouldn't get a connection at all.

Thanks.

I asked re: the modem settings as I actually can connect with different settings for some reason. If I play around and change the encapsulation etc it still works. However, as you said I was always under the impression this shouldn't be the case!

Yep, the modem is configured just fine. It would be useful if I could check your connection for you to ensure the line is okay. Could you please PM me your customer number?

Cheers,
Lon

Thanks Demeter!

I switched to the free Vodafone modem and I was very surprised to find it has better wifi range (in my place anyway) than the Netgear N600. 

However, unfortunately the very frequent disconnections persist. 

PM'd!

Pretty safe to assume right now that there is a fairly high chance of it being an internal wiring issue.

I'm just amazed - you would think that someone very senior in Telecom's system support area who lived in the house for 8 years would have had all the wiring sorted (I purchased the home from them). 

There's cat5e running from a jack in the study to a LAN jack beside the TV in the lounge - so he clearly didn't neglect the internet. 

And the jack labelled R-NGT trial in the study suggests that he was trialing new internet tech in the home. The Sky technician who came over to install sky said he used to work for Chorus and remembered the R-NGT trial from years ago.

Not necessarily. It depends entirely how the house was wired.

If it has a master filter for example (essential for the best ADSL2+ performance) this could have easily failed which would cause these sorts of issues.

What actual fault finding have you done other than swapping the modem and changing settings?

What exactly does the internal wiring of your house consist of - number of jacks, type of cabling, alarm, sky, filter(s) etc.?

What are the DSL stats reported by either of the modems you have tried?

Unless you provide this information, people here can only guess as to what the problem may be.

If the house was set up specifically for a trial technology that you are not using, that may be the problem.

I have fixed several naked-DSL connections with a master splitter install.




Chorus has spent $1.4 billion on making their ADSL broadband network faster. Why not spend a couple of hundred to make sure you are getting the most out of your connection?
Geekzone special price: $150* for master splitter install, normally $200+ through your ISP. Auckland and Waikato areas.
*Travel charges may apply. Additional costs may apply for complex installs.
I install - Naked DSL, DSL Master Splitters, VoIP, RBI Rural Broadband. Also a dealer for WorldxChange.

A HUGE thanks to Demeter who arranged for a Chorus tech to come check out the situation!

The technician called to say he was coming over and located a line fault somewhere out on the street and fixed it within minutes (before I could even get home to meet him!).

Zero disconnections over the past 4 hours - when it used to be every 10-20mins.

Now getting the below speed (LAN). Not amazingly fast for central Auckland but I'll take stability over speed any day!



Thanks Coffeebaron - I've actually had a few people recommend you and it's always been in my plans to employ your services.

Just need to keep the gf happy with a few essential purchases for the new home (lounge suite, new carpet for the bedroom etc) and then I'll be in touch re:optimizing the wiring!
