Man am I glad I called Snap to check on my order.

So when I called on Sunday night the CSR told me that the modem will be here on Wednesday.

Today is Wednesday I called Snap to get the Track & Trace number, and guess what the modem hasn't even been dispatched yet!!

Also the RFS for my connection is the 26th which is this Friday. Mmmm I sure as hell hope you don't cut my connection when I don't have a modem yet! (considering tomorrow is a public holiday)

The CSR said he was going to check with his manager to see what he can do....will be giving them another call if I don't hear back from them by 4:00pm today.

Mmmm not impressed so far. Hopefully all falls into place.

Why not use your own existing router until the new one arrives?

Can you use Orcon Genius modem on snap? I don't think this is possible?

Mm is it common for the sync speeds to drop when you move providers?

I was syncing at 16000 with Orcon and now im syncing at 12000.

You have interleaving on it seems, that can drop sync speed. if you were on LLU before that can also raise your sync speed. Snap don't do LLU so sync speeds can be slightly slower. I'd look at getting interleaving disabled if I was you, but it seems bizzare, because afaik Snap have interleaving off by default.

Hi,

I had exactly the same issue when moving from Orcon to Snap recently, but even at lower sync speeds I am MUCH happier with the internet experience...If you give Snap a ring they will *snap* their fingers and sort out your interleaving ;)

Cheers,

I called Snap and they advised that the order was placed with Inter-leaving off. But since the connection is new I need to wait 48 hours before the tools are available for them to run tests. So will contact them on Monday.

i have got a similar problem ....i joined snap yesterday... from telecom Technicolor modem and the fritzbox i have lost nearly 1mbit of speed connection (sync speed)....

i want to be the same as before or as usual every one hopes to have better .....but getting slower speeds is certainly painful when i payed for the upgrade to the 7390 model :(

i did ring up snap said we looking into it ....but they said really cant do much with the fritzbox sync connection :( .unless you can tweak it ?

Some modem chipsets sync higher than others on Chorus equipment
If your ISP is providing your DSL service using Chorus services/equipment and you change modem and get a lower line rate it's probably related to the modem chipset.

Chorus generally use two types of line cards in their exchanges/cabinets: Broadcom and Ikanos.

Modems/routers with Broadcom chipsets are known to sync at high line rates on both types on line cards than other chipsets (eg: trendnet, coneaxant etc).

There is a trade off made, higher line rate for less stability, the software has to make tough decisions depending on the line quality measurements. Some software/hardware is simply more conservative.

In the Fritzbox you should be able to see the make of line card you're connected to and from memory if you're willing to tweak in the Fritz you can adjust some settings to achieve a higher line rate.

LLU vs Chorus - LLU providers use lower noise margin
If you get a lower line rate after switching from an ISP using their own equipment in the exchange (eg: Orcon Purple Network, Slingshot Better Network, Vodafone Red Network) to an ISP providing service using Chorus equipment you will generally see the drop in line rate.

This is because Chorus uses a more conservative noise margin of 12dB where as most of the LLU providers on their own gear use 6dB. Noise margin is a buffer for stability of unused frequency. Higher noise margin more stable connection but lower line rate. Another trade off.

I wish Chorus would use 6dB by default rather than 12dB and only use 12dB for bad lines but NZ has lots of bad lines and you can understand why they chose to maximise stability/problems and go with 12dB.

Some modems allow you to mess with the noise margin and lower it yourself.

A small drop in line rate makes a big difference on slow connection and isn't noticeable on a faster connection
Generally for most of the population a 1Mbit line rate change doesn't make a difference as their line rate is >10Mbit but when you're on 2 or 3Mbit line rate a 1Mbit line rate change is a bigger deal.

Well with Orcon I was syncing at 16800 (close to 17000) now its at 12000 that's a drop of 4000 I don't think it should be that much should it?

that sounds about with for going from 6db snr margin to 12db snr margin.

the problem is that 6db versus 12db is a few megabit at like 8 megabit, a megabit at like 4 megabit, and 4+ megabit at 16megabit + .. it's not a small difference, and the speed gain is more significant when you're closer to exchange.

Well that's what I mean it doesn't sound right. Why would the noise increase? I can understand that the equipment is different so ok in compatibility +/- 1000 to 2000 but 4000 that doesn't seem right?

it's not the noise, it's the noise margin.

so if you get 40db of usable signal then 12db will make use of only 28db of it, whereas 6db will make use of 34db of it.
