10mb -> 20mb, upgrade procedure ?

Anyone tell me what the price is for adsl 20+, telkom website seems to only mention vdsl.
 
Is a vdsl modem required for this or will a normal adsl modem work?? Phoned telkom but was told I need a vdsl modem.

Telkom will try and put you onto VDSL if they can, if not they use ADSL2+ but they wont actually tell you whats being used. VDSL you will get a higher upload speed which is nice if you want it.

I got to 20mbit adsl2+ bought a VDSL modem, found I couldnt get a VDSL sync (no matter what telkom did their side or mine) and had lost the reciept so now it sits in my cupboard.

Set your current modem into ADSL2+ and see if it sync's, if so then you're 1 step there.

Checked dsl availability 18 times.

Current 10
Available 20.

Pop into Telkom store on Sunday. Do application for speed upgrade.
No problem.
3 Days.
Will get SMS when done.

6 Days later, asks wife if she got sms, cause speed is not increasing.

"Yes, they phoned me yesterday, saying we cannot upgrade. There is obesity or gum or something on the change."

OK.

At least I now know why.

My ADSL availability says:

Maximum available: 4Mbps
Current service speed: 10Mbps

I'm on 10mbps and it's perfectly stable. No sign of 20Mbps though.
 
Current line stats :

Anyone take a look and let me know if line will handle 20mbps

I see exactly the same thing when using the checker. Just goes to show that the ADSL checker website is completely whack :wtf:

PS: I'm also running 10mb and have a stable connection.

It shows 20Mbps attainable rate. But if you look at his SNR, it is only 12.4db while syncing on 10Mbps, so chances are he will get closer to 14Mbps, possibly 16Mbps, and his SNR will drop to around 6db when he sync at those speeds. I talk out of experience, being on a line that sync at around 13db while on 10Mbps, and it did sync at 16Mbps at one stage.

What is the price for VDSL same price as 4/10 ADSL fee or in the price range of elite etc

R100 more to go from 10Mbps ADSL to 20Mbps VDSL.

If your attenuation is very good your speed drops are next to nothing, between 4mbit and 10mbit my line stats didnt change and from 10 to to my SNR dropped by probably 3 points or so. If I do a speedtest I get 17.5mb at a 20mb sync with the the following attenuation's...

Downstream Attenuation: 17
Upstream Attenuation: 10

I speak from experiance too as someone who went from 4 to 10 to 20 just under 2 weeks ago.

EDIT: Remember SNR drops over distance so the closer you are the less it hurts, I'm 1,3km+- away.

Wrong.

Attenuation changes based on distance, thus drop over distance.
SNR is based on how good the signal is. The higher the speed, the lower your SNR drops, because more of the available signal gets used. It is impossible to stay the same on different speeds. You may speak from your own experience, but you are also talking out of your ass. Go read up on how SNR works before you start an argument you can't win.

Additionally, the guy's attenuation is far higher than yours, there is a good chance he can't keep a stable sync at 20Mbps, but is 100% fine at 10Mbps. It is also very probably he will sync between 14-16Mbps with his specific attenuation.

Not wrong, you just agreed with "thus the drop over distance". You just assumed I was meaning SNR has the same relation to distance that attenuation does.

Attenuation is tightly related to distance, snr when combined with a speed (say 10mbit) will be vastly different at 17 attenuation compared to say 35 attenuation thus snr does indeed drop by distance it just requires a speed pairing. It gets affected exponentially as distance and conditions change thus it is not tightly related. That's why I mentioned the drop over distance.

I can only assume that from 4-10 megabits my attenuation was good enough for there to not be a measurable difference, 10-20 I did say it dropped some points (See above where exponentially mentioned), feel free to believe that it's "Talking out my ass", I dont need to prove myself to people like yourself.

You may go eat some humble pie now.

ROFL. I still disagree with you, and you are wrong. It is possible that at a very low attenuation SNR doesn't drop much with higher speeds, but that doesn't make it a fact or true. Because that is the exception to the rule, where almost always, SNR will drop as the speed goes up. Taking the exception and saying it is the rule...is talking out of your ass.

That said, I have realized this is wasting time, I will not carry on with this pointless argument. Please just stop spreading incorrect advice where possible.

Thinking about it further I'll agree with you that taking it as the rule is not a good way to treat it, it was confusing as hell to me because it was not normal.

I got annoyed by your comment on the SNR, granted I didn't put it as clearly as I should but when something I meant gets told back to me in a different way and then told I'm wrong is one of my pet peeves that I cant help but sort out. I don't mind being wrong I cant stand being misunderstood.

Have you ever encountered the migration profile being worse snr than the final 20mbit because when I got put onto 15mbit migration my snr dropped considerably but on the final 20mbit that TelkomZA put me on the stats rose again (Not as high as 10mbit of course) ? I got messed around by Telkom so I bounced between 15 and 20
 
Ok. So opinion worth going the 20mbps route with my line? Would I have sync issue even with 15 mbps?
 
Why not try and see what happens ? Its not as if you can't get turned back

You won't get 20Mbps. And you may have issues at 15Mbps. May, but you'll never know unless you try. You're going to pay for 20Mbps though with your ISP and Telkom. You need to ask yourself whether it's a) worth it, and b) is your internet essential, and can you afford to be offline for any point in time?
