Hi, all

As before, I used a wireless router to access Internet. I needn't to config the network cards because it could find the network automaticly.
When I change to use an ADSL modem, I could not find any dialer program to establish a link.

And more, I found once after I restarted the system, I found hard disk partition icons displayed on the desktop, and when I pluged a USB storage such as a flash disk, I could not find it, in anywhere!

I chose GNOME as desktop environment.

How to solve them? Thanks!
