Hey Geeks

 

I’m currently in the throes of a broadband investigation and could use some input from you geniuses.

I live out in the country, about 10 minutes’ drive from the nearest city and 4km from the nearest whisper cabinet. I receive ADSL internet from Slingshot and use a Draytek Vigor 2830vn Modem/Router.

My speeds have always been poor (obviously) but the first few times I changed internet plans with Slingshot my speeds did increase. For the last year or so now my speeds have been sitting under or around the 1.2Mbps area with a ping of 45ms to Auckland.

Everything was going swimmingly until just over a month and a half ago; suddenly I started experiencing slower speeds around peak times which progressively got slower until I was experiencing serious drop outs fairly regularly.

This meant browsing the Internet became near impossible (let alone gaming or using teamspeak/skype). I performed isolation tests (removing filters and plugging the phone line directly into the modem and connecting only 1 pc, switching phone jacks etc.) and no difference was made, I’d still get crazy ping fluctuations of up to 2000ms and speeds down to a few Kilobytes per second.

I called Slingshot and requested that Interleaving be turned on, this resulted in my non-peak speeds increasing to 2.2mbps Laughing and my ping to Auckland increasing to 65ms Undecided (which is to be expected).

While I have now seen a massive improvement in speed during these peak hours of 6pm to 10pm weekdays and all day Saturday, the speed still drops to 0.8mpbs at times and quality of connection (which is the key here) is still poor, resulting in bad VoIP quality etc.

However, my upload speed has remained a rock solid 0.45mbps throughout the whole affair.

I ran a test using the diagnostic at www.myconnectionserver.com and received the following results:

 

A basic analysis:

A Graphed analysis:

(Hyperlinks don't seem to be working sorry, just copy paste!)

Note that in the graphed analysis, the upload speed is fairly stable and the wait between TCP packets is acceptably low. But it’s a completely different story for download. As you can see the wait times between packets at times are gigantic and the stability of the speed is very eratic.

Do any of you Net Boffins know whether these download problems are being caused by hardware (exchange/cabinet etc.) or if there is something more sinister at work?

Any insight into this would be awesome (and do check out that site if you are a novice, it explains a whole heap of things and has some very useful tools).

Cheers,
Incindre

The exchange you are connected to is ADSL1 only
This is due to be upgraded by end of 2013, so atleast 1 year away.
Your broadband will continue to get worse until then.

- A master splitter will help marginally
- A master splitter will help more significantly once exchange has been upgraded
- An RBI solution will give you immediate improvement now.

Flick me a PM or email coffeebaron at geekzonemail dot com if you are interested in either of these options.

Cheers
Fraser




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.

I think I'm ready to close the thread.

I confident that the wiring (including the internal) is fine and my problem lies within the little white shack that is probably having a hard time coping with some new-arrival heavy-user(s).

Thanks guys, I understand things better now, and if it's true that nothing can be done to deal with congestions issues, I'll just have to live with it until 2014

Cheers to everyone who contributed!
