DSL slows down from 5pm every night

I used to be able to get 4 mb/s connection, it eventually dropped down to 2mb/s and they claimed it was distance/contestion. I downgraded my subscription and accepted it.
Last year some one cut my cable in several places, didn't steal the line (just someone being an idiot), Telkom came and made awful cable repairs (the one looked almost like a literal knot), I then got a really bad SNR and my speed degraded day by day to 200kb/s. There was a cross-connection too (where by I was syncing through another number and getting 4.8mb/s connection again with double the SNR - which makes no sense to me) that person obviously complained and I got my junk 200kb/s again, almost 5 months to get a tech out here, they fixed all the previous bad repairs but kept trying to push LTE on me.
The line is running at 2 mb/s with a poor but acceptable SNR/attenuation (I am 4.2 km from the exchange) however this is only from 8 am - 5 pm, from 5pm the SNR degrades and so the line adjusts to 500 kb/s it is so bizarrely on time that I bet i could set my watch to it. I am going to try get them to come back out (but I think I may lose my mind if it is another 5 months), any idea why it loses speed at a specific time? There is apparently 20% free space on the port allocation.
 
Only thing I can think of is Tropospheric propagation but that shouldn't really apply to DSL.
You probably have cross-talk at the time as multiple people access the line when they get home. You're just going to have to wait on a tech and hope he/she sorts it out.
 
Thanks for the reply, I thought about that (other users surrounding me), the thing is, it's even today, like it is literally every day at 5 pm, so it may just be a single user with very specific internet habits. Something I missed in OP was that when it rains I get almost triple the SNR and a solid 4 mb/s, so I was thinking it may be something electrical that some one around me unplugs during the rain and its on a timer, but I don't know if that's possible.
 
I had the same problem. My snr would drop so much that the line would drop. Normally from 7pm to around 11pm. Telkom had to change a few settings on their side to get it working again.

I have a feeling that their exchange are heavily congested.
 
You have stated where your are. Have you tried to check for known faults in your area? Do you know which exgnage you are connected to and which DSLAM?

Use this website to find out.

Click on the look up DSLAM and enter your DN number or line telephone number if you know what it is for your line, or at least the area code for your area. All outstanding faults in your area will be listed.

What you have is unfortunately probably related to very shoddy workmanship during the repair process. Crossed line, split pairs and poor joints are the result. You report worse performance during bad weather which means water ingress or even moisture only, which will kill the service. Time dependent performance issues means another user or more than one with very regular access habits is connecting at the same time increasing cross talk levels, made worse by split pair problems.

Your only hope is to try and get the fault escalated to the point where a special investigation is triggered. Ask MickeyD to help by posting your area and he may know who to contact in OpenServe.

The odds are against you already being at very edge of the normal ADSL line length (4.2 km). So you need everything to work almost perfectly to get any sort of decent service at the best of times.
 
Hi, actually my line quality and speed double during rain, I get 4mb/s and my SNR is 16 where it is usually 8, I know this makes zero sense to me at all. This is what made me believe that it maybe electrical interference along the line from a nearby house (that they switch off whatever it is during rain).

A special investigation was kind of made available, basically 3 people showed up I showed them the bad cable repair they said I must get LTE but also fixed the knot, however they didnt put in a stay and the line is very near an electric fence belonging to a neighbour (I dont know if the electrical field can by-pass the shielding in the cable, maybe there isnt any real shielding). I asked them if they could bury the line and they said only if I pay for it which I thought was a cheek since there are only 3 houses on the line the rest of the houses are town houses and have their own underground cable (they never have speed issues).

The area is Buccleuch I will check out the link/tool you gave me.
