ADSL Line issues

Hi Guys,

I just want to run something by you guys, just to check if my understanding is correct.

Since the 3rd of October I've had very weird issues with my ADSL line. There was a big storm in Kempton on the 3rd and since then my line has been very uncooperative.

So I've logged a couple of tickets with Telkom and they have done several port resets and sent a technician out to look at my problem and apparently fix it.

So has been happening since last week is that during business hours my line syncs at 5533kbps, but from about 18:00 my line drops and then will only sync at 1300kbps.

Now my understanding of a congested exchange is that my line will sync correctly but I will not get the full speed? Is this correct or not?

Has anyone else experienced a similar issue?

My neighbor in Kensington was having the same problem, seems like an exchange issue.

A congested exchange won't effect the sync speed, what is your lines attenuation and SNR?

Hi There,
I suspect that it is a line issue rather than an exchange one. Your attenuation is not so great nor are your margins.

If you use the phone is the line clear or noisy. If it is noisy then place a voice call. Sort the interference out and your data should improve.

Regards

Tim

Wow, I have exactly the same issue.

Every day from about 18:00 until 22:00 my SNR margin takes quite a dip - usually sits around 10.6dB (4Mbps profile) but as soon as 18:00 hits, my line will drop and re-sync at around 3Mbps. As well as the SNR drops down to 6dB (whilst syncing at 3300kbps +-). After 22:00 or 23:00 the SNR returns to normal and so does my line, very strange...

I've been through the usual processes with Telkom, and have basically been told that there is nothing that can be done about this type of problem as it is a "line interference" issue, which could be caused by something such as somebody switching on their electric fences in the evening, street lamps powering up, etc.

Quite pathetic if you ask me.

Hi Guys,

Just a followup, seems like it was a noise issue. Noise has been sorted and line seems to be running well again. Knock on wood

seems lots of peeps struggling after last weeks storm in Jhb.

I'm int he same boat, endless issues. Telkom techie simply sees the line making connection and marks it as fixed. Logged ANOTHER fault, at least this time the call center lady was more helpful and agreed with me that line attenuation/noise is unacceptable.

Hilarious call with a Neville at their call center, guy insists i take this up with Afrihost/Openweb/Fnb adsl (i use all 3), says speed is their problem not his. We argued for 5minutes with me saying its not browsing speed, but rather the actual data connection and line thats faulty.

this does not look normal right?

That is definitely not normal, you would have really bad packet loss with an SNR of 3.8dB.

Granted you are quite far from the exchange, based on your 50dB attenuation - with a decent router you should be able to sync very happily on a 2Mbps profile with a decent SNR margin.

Keep on Telkom's ass, moan on Facebook, they seem to be a lot more helpful online!
