Dear sir,
I GUESS your still using the dial-up internets connection provided by Lanka Internet as you mentioned about some connection wit Lanka Internet. If that is the case (which am not much sure of), I would like to suggest you to try ADSL broadband internet provided by SL Telecom. It would give you an oppurtunity to try and make use of PLUG & PLAY technologies of this MODERN ERA. Which could also lessen the chances of error and help you FORGET those old days and MOVE ON
Yours,
X.
