New PC...New and BIG ADSL connection problem

[Opeth]

Hello!

This is my first post, and it brings up an annoying problem.

I´ve just made an upgrade on my PC. Basic specs:

AMD Sempron 2800+
ASUS A7N8X Deluxe
2 x 512 MB Kingston Dual Channell
200 GB Seagate HD
MSI FX5700 Graphics Card


I have a ADSL provider (Telemar/VELOX - Brazil) and I kept my old 3com Homeconnect Dual Link ADSL modem.

I run Win XP PRO SP1 and had been using the modem (with the old PC - USB connection) with the help of RASPPPOE.

Well, since I upgraded, my connection is killed right after I input my username and password. The LEDs seem normal, and the connection to the ISP´s authentication portal is ok too.

But the connection is ALWAYS killed after I press "ok" on the portal.

Can anyone help?

Thanx in advance!!

Opeth

PS: Win XP´s firewall is off. RASPPPOE identifies the modem and creates a connection for it.

Are there any bridges in device manager under "network adapters"? Have you tried updating the chipset drivers since the upgrade since you are using USB? Might also check the "idle timeout" settings for the connection properties.
