Sup guys

I was bumped down to 4meg from 10 meg, I phoned telkom and the operator told me that he could only bump me to 8meg? I WANT 10!!!!!! how can i do that?

Don't we all want 10 meg...
8Meg is still super super fast! Good for nearly 900kB/s
Not so long ago (15 years ago?) LAN's couldn't even achieve that speed.

More like 30 years ago but yes, he should be more that happy with 8 meg
 
Post your line stats here and lets take a look if Telkom are just making it up or if you are indeed in that range of instability.

lol dude. You just being greedy now. Take 8meg and go sleep.
 
If he's been bumped down he has the right to know why, and at least to ask why, for being a paying customer. It's IRRELEVANT whether 8Mbps is "good enough" - he came here to find out why he's on 4Mbps even though he was on 10Mbps recently.

whippey: 0800 375 375. Nobody here can actually solve this problem for you - you'll have to query with Telkom. You're welcome to bring the issue up here, but then at the very least you should tell us what exchange you're on, or if you don't know then provide your area code and first 3 digits of your phone number, then you can see if others have had a similar problem, and what region they're in.
Also, as Hellhound said: post your ADSL line statistics so we can see if Telkom downgraded you based on your distance from the exchange. THAT's what this forum is for. We're all just enthusiasts who can use this platform to share and exchange knowledge and experience - nobody here actually works for Telkom etc.

Everyone else (who told him to live with 8Mbps): shuddup. He didnt want to know anything about 8Mbps, and I'm sure if any of you were downgraded even from 10Mbps to 8Mbps you'd all have fat whinges. Really pointless responses ^_^

Question: If My attainable download rate is 7500kps and my Upload rate is appalling, like 360kps, could I get my line bumped to 7mb/s or 6mb/s? Or is my horrible attainable upload rate not going to allow that? Sorry if its a bit off topic :D

Thanks man, all I wanted to know why the people at telkom got me bumped down to 4meg with no reason.
Connection Speed 7520 kbps 640 kbps
Line Attenuation 43.0 db (down) 25.5 db (up)
Noise Margin 5.5 db 12.0 db

I know they seem bad, but the line is very stable. I dont see why telkom down graded me straight down to 4meg, they could of just brought me down to 8meg based on those stats. My exchange is the Clareinche exchange, 021-683

Hate to say this but at those noise margins you aren't actually solid on 8Meg since even in that copy and paist section you're only really sincing at around 7.5mbits which means your pushing your luck as it is. I think personally they should be able to bump you up to 6meg comfortably but 8meg with a Noise Margin of 5.5 or lower is VERY VERY close to unstable.

If Whippey says he was syncing stabley on 10mb, I trust that, regardless of his line attenuation and noise margin. If he was syncing at 10mb and it was stable and not dropping, then there is no reason for telkom to push him back down. The least they could have done is let him try it out for a little longer to see if the consistency remains.
 
It's like practically impossible to sync at 10Mbps at 43db downstream attenuation, if your noise margin is 5.5dB on 4Mbps. Maybe you can defy my somewhat knowledgeable intuition - but even if you do, there's no chance it would be a stable 10Mbps. Whippey, somehow I really doubt your modem ever saw 10Mbps, or ever will see 10Mbps unless you can lower that attenuation, and increase that noise margin. You can try get them to put you on 6Mbps and see how that goes... I've got 35dB attennuation and my noise margin is 16, and even I am hoping against the odds that I'll be able to get a stable 10Mbps. Your modem isnt syncing at 4Mbps at the moment, but at 7.5Mbps. Now the problem with syncing at max attainable rate is that if the conditions fluctuate you might drop sync, so try get Telkom to put you on 7Mbps, if that's even possible, otherwise go for 6. Rather get a stable, consistent 6Mbps, than a dropping unstable "7.5Mbps" which never even hits 5Mbps throughput anyway

yes i was, was syncing at 9566 kbps! With no issues at all.

OK, I got 9566 kbps down and 1016 up. I was downloading at 960kB/s to 1Mb/s, played online games and all; with no issues at all.
 
Ah, ok well very nice then. What modem do you have, out of curiosity?.. Seems to sync really well under non-ideal conditions :P If you really managed 9566 at a stage, then a few things recommend to get back there, from my own experience:
- Get your ADSL modem as close to the demarc point in your house as you can (where the wire from outside comes into your home)
- Replace the phone socket at that point if you can. Something new that's good quality - they usually come with a small 'between the wire-pair' gas surge arrestor. Telkom can replace this for you if you call them out
- Try get Telkom to rewire/rejoin possibly corroded joints or old copper leading to your house. If possible, get them to replace old straight-through wire with proper adsl-compliant TWISTED PAIR telco wire which helps with noise.
- Try the modem on the line ONLY. So unplug EVERY phone or fax machine, even surge protectors and filters, and see how that affects your stats
- Try get yourself an ADSL POTS filter. I'm not talking about the normal telkom-supplied POTS filter that only has a port for phones, but rather about one that has a DSL port as well: this will eliminate non-dsl frequencies and give your modem a cleaner signal to work with (this helped me quite a bit)
- Keep the phone wire away from AC (wall power socket) wire because that can cause noise/humm. Try not to run your phone line parallel to an electric fence, for example
- Try another modem? Yours seems to sync really well, but maybe another will be even better? ;)
Some of those things could help you reach 10mbps again. process of elimination: find whatever is adding attennuation or noise, and get rid of it.

I personally think this whole line attenuation and noise margin is not as accurate as everyone thinks. Whippey has no reason to lie about what he was syncing at and I therefore believe him. Which makes me come to the conclusion that line attenuation and snr is not an accurate or true reflection.

Fragtion: While my line hasnt been upgraded to 10mbs yet, I have seen my downloads peak up to 1,2MB/s and then 800KB/s, for a maximum of 5 seconds, then it goes back down to 480 - 500KB/s.

Wanna guess what my line attenuation is currently? Worse then Whippey....

My line attenuation sits at 51.1dB downstream and my SNR sits at 7.05dB downstream. Yet my 4mb line is as stable as a rock. I have not experienced any drop in syncing. I download between 450 - 500KB/s, excluding the random spikes.

Here is a screenshot I just took from a download im busy with.

You do realise that this is more likely to be your download manager missreporting speeds than you actually transfering at those speeds, in fact you shouldn't even be able to get 480-500KBps consistently unless you are syncing at greater than 4096kbps. 4096 is roughly 512KBps less the 10% overhead estimate would give you a max consistent speed of roughly 460KBps.
