Their technician should bring out a spare modem to show you the 8 megabit speed. But it's an ISP issue at this point.
Recently i used the wireless modem:
R-ADSL-C4W-EG Dynamode Wireless Modem
Plugged it into a 100Mbps PCI card adapter
We have 8mbs internet!
However it ran very slowly when using it, slower than dial up!
Anyone Please Help!!!! A.S.P
