Similar problem over here after migrating to Afrihost.
Initially I needed a cancelled lined reactivated. However before the new number was active I was somehow using the old owners 2mbps adsl line (Phone calls not working plus no dial tone) - just sort of checked by chance if there would be some miracle adsl connection.. and viola there was haha. Okay so 1 week later telkom technician comes out and gives me my new number and 'activates' the ADSL on my new telkom number - I placed an order for 4mbps but ended up getting 2mbps installed instead... anyway.. On his way out he mentions that the exchange has been upgraded to platinum/diamond whatever and we can now get 20/40mb VDSL. SO now ive migrated to afrihost, and on my client zone it shows the line has been upgraded to 20mbps VDSL and when calling Telkom they confirm the same. BUT its still syncing at 2mbps on my router?? The afrihost guy says the line is not syncing at all and it shouldnt even connect as my VDSL router is not L2TP comaptible....
Anybody out there able to shed any light or give any advice as to a way forward??
