There is nothing wrong with your line, or the mweb profile and any other cosmetic rubbish the call centres fiddle with. This is a classic example of congestion.I have a 100/25 Octotel/Mweb connection in Brackenfell. Before 20h00 and after 22h00 I get exceptional speeds - latency 3ms, jitter 1ms, download 99 Mbps, upload 25 MBps. Between 20h00 and 22h00 my performance is abysmal for gaming and on weekends for downloads too. In this time slot, from Mondays to Sundays, my latency would increase to ±75ms and the jitter to ± 50ms. The latency increase makes games on international servers unplayable (increasing from ±150ms to ± 225ms) and when coupled with the high jitter even games on South African servers become unenjoyable. My friend's Vodacom 100/50 connection gives him a constant ±150ms ping on international game servers during the same time that mine deteriorates. On Saturday and Sunday evenings my download speeds also come to a crawl in the low teens.
I have reported the problem to Mweb and tested my connection by establishing a wired connection to the ONT only. I have repeated this test every evening over the last month with my desktop and a laptop and the results are always the same. Mweb has recreated my profile on their side and state that Octotel has tested my line and that everything is in order. But it's clearly not.
I don't actually know where to go from here as the service is unusable for my needs between 20h00 and 22h00, exactly when I want to and have time to use it.
By then I am hopefully overseas or on Openserve FTTH.The more people move OFF ADSL, the better the service gets for those that stay with ADSL.
The problem will arise when Openserve decides to shut down ADSL in an area because there are too few customers to justify keeping it going.
