Since getting 4mb uncapped ADSL last Monday I had random low speeds (often below 0.8) and disconnects every 10 mins-2hrs that were only resolved by resetting the router. The router (Netgear N150) remained synced but the internet light went red and there was no connectivity. Resetting the router seemed to temporarily correct the problem, but obviously having to constantly reset the router and put up with random low speeds is extremely annoying. I reported this problem to Telkom and two days later they said that they fixed the issue and closed the report (without notification), but nothing changed and the disconnects continued. I then reported the problem to Afrihost and double checked router settings etc. but found everything was correct on my side. As suggested I also tried a different router and the problem persisted. SNR margin (12-14) and attenuation (32.5) seem fine and I can view them at all times even when the net has dropped.
Four days ago router resets stopped working and I was constantly without internet. Shortly afterwards, the net at my work (which has been working for over a year without issues) had the same problem. Synced but no internet, and resetting ports and resetting the router made no difference. My work is only about a kilometer away and is on the same exchange, so it seems to be an exchange issue. Today Telkom supposedly fixed the problem and I managed to get online again at both PCs after they reset the ports.
However, now it's back to the original random disconnects on my new line. Does anyone have a clue what the problem is here and how to convince Telkom to fix it? They just seem to be completely failing to grasp the situation (as usual).
