Just wondering if anyone can help me...

I'm running Mandrake 9.2, and want to connect to the internet through my Sagem USB ADSL modem.

The internet connection wizard in Mandrake control centre detects the adsl modem, and the fact that it connects using PPPoA. When prompted to enter my ISP details, (ISP name, DNS servers, username and password) I do so, but the system is unable to connect to the internet. Any ideas why?

Virtual Circuit Identifier - VCI
38

Virtual Path Identifier - VPI
0

Encapsulation Mode
VCMux

Authentication Type
CHAP

Protocol
RFC 2364:
PPP over ATM (PPPoA)

Modulation Type
G.DMT or Auto

Tiscali Primary DNS Server
212.74.112.66

Tiscali Secondary DNS Server
212.74.112.67

That is the info from my ISP. Is there any was that I can check all of them are correct, not just the ones I can see in the control centre?
