Hi,

I noticed a few people talking about turning interleaving off... just wondering:

What is it?
Why do people turn it off?
How can I turn it off?

I am on xnet's lowest plan at the moment (256/128)

Thanks.

Cut me some slack, I've been googling stuff all night, and this forum doesn't appear to have a search engine. It fries my brain after a while. Besides, isn't the purpose of this forum to answer questions about broadband?

illegalbrain: Hi,

I noticed a few people talking about turning interleaving off... just wondering:

What is it? A METHOD OF ERROR CORRECTION FOR YOUR ADSL LINE
Why do people turn it off? TO REDUCE LAG
How can I turn it off? ASK XNET TO DO IT FOR YOU (there is no charge for this)

Before you do this, have a read of the INTERLEAVING section from the following document:

http://www.xnet.co.nz/pdfs/terms_xnet_acceptable_use_policy.pdf

This explains a bit more about it.

Okay, just to keep johnr happy :) I googled lag, and it seems its mostly a concern for gamers, does it have any meaningful effect on anything else?

That article from xnet talks about a possible decrease in quality, is this talking about having a noisy line or a slow connection or what?

Thanks again.

try searching google for interleaving, it's not that hard, really.

you should leave it on for a better connection. but if the difference between 50 and 60 ms is that important to you..

YES. It will have adverse effects on VoIP services such as VFX, Skype etc.

You may get some packet errors in your data. But TCP/IP stacks will take care of that anyway, so unless the errors are very bad, it won't matter.

Given that your modem is reporting a Downstream speed of 7616kbps, that's as near to a perfect line as you are likely to see, so I wouldn't expect you to have any problems with errors on your line.

Another thing you can check is Noise Margin and Attenuation Rates (via your modem's web interface), then interpret them according to the following table (provided with acknowledgement to Whistleblower):

SNR Margin
In general, a higher signal to noise ratio will result in less errors.

6bB. or below = Bad and will experience no line synchronisation or intermittent synchronisation problems.
7dB-10dB. = Fair but does not leave much room for variances in conditions.
11dB-20dB. = Good with little or no synchronisation problems
20dB-28dB. = Excellent
29dB. or above = Outstanding

Attenuation Rates

In gerneral, attenuation is the loss of signal over distance. Unfortunately, dB loss is not just dependent on distance. It also depends on cable type and gauge (which can differ over the length of the cable), the number and location other connection points on the cable.

20bB. and below = Outstanding
20dB-30dB. = Excellent
30dB-40dB. = Very Good
40dB-50dB. = Good
50dB-60dB. = Poor and may experience connectivity issues
60dB. and above = Bad and will experience connectivity issues

Bizarre, did you go back and edit your post just to sound even more up yourself?

My previous response was to your unedited post, which said "WTF? Did you google for lag?"

Don't worry about this... You will notice a lot of people write stuff, submit and then realise that there's no need for some words, then edit the posts. Normal life...

Have a good stay on Geekzone!

I know what you're saying, but in this case he actually edited it in order to [I]add[/I] unnecessary comments, that's what I found so bizarre.

Guys, guys... Calm down a little!

As the OP in this thread, Illegalbrain had a valid question which I have answered to his/her satisfaction.

Next time, some helpful replies instead of smartass comments about Google would be appreciated. I'm sure by now that everyone is aware of Google's capabilities, so there's no need to point it out really. It doesn't add anything useful to the discussion.
