Hey I'm using Diamond Multimedia SupraExpress 56e pro. This modem is supposively a good external modem. I managed to get the net going by configuring:
(in GNOME) Start >> System Settings >> Network
HOWEVER the net speed is really, really slow. As in I was downloading rpms @ between 0.8 ~ 1k/sec. Hence I've been downloading the rpms with my Mac OS X (in average 5k/sec). So yeah is there anything I missed out in the configuration? I haven't enabled ANY compression.
Also when I go to "activate(connect)" the device, it will successfully connect to my ISP but will not show "Active" in the Status. Pretty weird stuff. The only reason I know that it has connected is because the dialog box thing has gone away.
I've attached several screenshots that may help you to diagnose the problem.
update - forgot to mention that I'm running FC1, not FC2.
