Is it internet explorer that won’t dialup? Mine did that, I set dialup settings in IE to “dial whenever a network connection is not present”, then restarted IE, it connected fine. Then set back to “always dial my default connection”. This appeared to reset the connection, maybe it was corrupted. I tried everything else in faqs and other internet forums to no avail, but this worked for me.

Mine happend a while after avast was installed… So it was probably just IE goin funny for some reason, been ok since.
