Telecom has recently upgraded the roadside cabinet outside my house and I can now get ADSL2+ Yay!

My modem now says its getting 16,877kbps downstream and is connected as ADSL2+ when before it was only getting between 3,000 & 4,000kbps. However when I run the Slingshot speed tests I’m only receiving 4400kbps even though I’m on a full-speed download plan. I called the Slingshot helpdesk and after going through all the standard diagnosis stuff (which was all fine), Slingshot told me I need to do 2 things to receive ADSL2+
1.) Ring telecom (123) and asked for my profile to be moved from ADSL to ADSL2+
2.) Change to a new Slingshot plan (from Extreme-6 @ $40/month to Fire @ $50/month)

I rang telecom and they say there is nothing on a profile that can be changed for ADSL & ADSL2+ and there is nothing they can do.

Does anyone know what Slingshot are on about?
Do I need change my ISP to Xtra to get ADSL2+ speeds?

hey dude, I presume you are with slingshot - judging that you changed your plan.
There is nothing to tweak -- possible you will need to tell slingshot to have the lowest latency as possible - that is turn off the interleave but it should not see much of the difference unless you play online games

how about going to speedtest.net and test it from there.....
Test your download speed with various test sites.

Yes I?m with Slingshot, but haven?t yet changed my plan as it doesn?t happen until the monthly rollover which is 2 weeks away. It concerns me that the Slingshot helpdesk ask me to call Telecom to change my profile when this is not the case. I?ve lost confidence with them so I think I?ll switch to Xtra.

Hi, you will need a Fs/Fs plan not a Fs/128k plan to realise speeds beyond around 4-5Mb/s, quite simply on a typical setup with 128k upstream you cannot acknowedge packets fast enough for the downstream to go much over that.

I am not familiar with Slingshots plan names, but from recent experience Xtra is definetly well ahead of the pack compared to many ISPs including Slingshot.

What's your upload speed? If you're on a FS/128k plan you'll only get ~4.5Mbit/s download wether you're on ADSL2+ or not.

You will need to upgrade to Inferno to have true ADSL2+ speed :)

the fire plan that you upgraded - it is Full speed down/128k up -- meaning you are still capped

Most of the things you download now you have to give and take :)

Hi Richard, yes depending on the setup of your TCP stack which varies depending on what version of Windows or Linux you have and how its configured you can get higher than 4-5Mh/s. however for stock standard Me/2k/XP installs dont expect much more than that, other OS's and tweeked OS's will give better.

The bottom line still is that while you have a 128k uplink some level of downlink ceiling will be imposed that can only be sorted by increasing the uplink speed, if you want higher download speeds then just get past this limitation and overcome lots of unkowns in your own ADSL link and the way your TCP stack behaves with it.

Cheers

I?ve now moved to Xtra and am getting 14.39 Mb/s download. That is more than 3 times the speed just by changing my ISP!

I'm one very happy xtra customer.

Well done!!
