Would syncing at lower speed help latency?

Ever since the Telkom upgrade, my line has been virtually unusable after hours , between 5pm and 11pm or so. I am now on a 2mbps product. I have local pings of 200ms-1000ms regardless of ISP.

Would downgrading to a 1mbps help with the latency?
 
Nope. That wouldn't change anything, unless you can get Telkom to downgrade ALL the 2Mbps users to 1Mbps and the 1Mbps users to 384kbps again.

There are hundreds of people suffering from the same congested exchange/DSLAM issue that you seem to be having.

Could you do a traceroute to like www.google.co.za and post the results here?
If the latency on the 1st hop is like under 1ms and then the one after that is suddenly like 100ms+, then you're most likely on a congested exchange/DSLAM.
 
Well latency is inherent to ADSL as a technology, so basically it should remain the same regardless of your line speed.

That is of course when there isn't a problem with the line in question, so yes it might very well improve as your line is probably suffering due to a lot of noise and interference.

This is taken from 5-6pm, and continues until roughly 10pm. The 192.168.1.1 router is my DSL router, I use a spare 3G wifi 10.0.0.1 router as a wifi access point. However, the results are the same if I run the tracert from the DSL router. To add to this, my line stats stay the same all the time, and the router shows I have a theoretical down speed of 10mbps+ and upload of about 850kbps+. I sync at 2mbps DL, 512k UL.

That definitely looks like congestion!

You can try to log a fault that you're experiencing very high latencies and slow download speeds, but it could take a very long time before Telkom actually fix it.

Its damn horrible. The internet is useless after hours, and before the 'upgrades' it was perfect all the time.
 
Hi There,
Well it is not going to be something that is fixed overnight but I would suggest that you place regular fault reports and cite the figures that you have.
If you can build up enough momentum there then it might get addressed.
I am sure though that Telkom will know the time that it is congested anyway and resolving it is not a simple thing for them to do.

So patience and regular reporting id the route at the moment.

Regards

Tim
