First time Telkom ADSL advise

Hi Guys,

Please note this is the first time i am trying this adsl thing.
I applied for the telkom uncapped 1mb package which was installed yesterday.

I did the basic setup myself with the username password ect.

Browsing is fine but when i want to download something the speed is like 20kbs. Is that right? cos in my mind thats pathetic.

This morning i tried from the same site and it was downloading at around 128kbs

Is their throttling of line speeds in the afternoons or something?
When i spoke to the women she said there is no throttling unless you get flagged for abuse.

When i checked my exchange allows up to 4MBS so why is it so slow?

someone said i need to visit a link to verify the line? is that true?
