I've had this problem for +- 7 years
We use to have a 4mb line but we were lucky if we could get a 1mb sync.
I spent hours on the phone with telkom with multiple call-outs just to be told nothing could be done or they can't find anything wrong
The faults were very erratic as well. it would work fine for a few days and then go down again for a few days.
Finally we went down to a 1mb line because Why do I pay for a 4 mb line if my speeds is brought down to 1mb anyway just so that i can sync.
And the problem only gets worse. Some days I'm lucky to get a 300kbps sync.
Apparently my closest exchange is in Lynnwood and if that's true then everyone in my area is struggling. There are Millions of businesses in my area as well , Why not build an exchange here???
Also if it rains then i can forget about a connection for at least 2 days!!!
Number: 012 361
Line Speed: 1mb (was 4mb but useless)
ISP: Mweb Uncapped
Time of day: happens randomly anytime of the day.
