Hello,

Finally installed DSL to my laptop's (Toshiba Satellite 220CCDS) HD, and I'm not going back to Micro$oft anytime soon. But I do have one problem, though; my LAN card doesn't seem to want to connect.

I see the 100M indicator on the card flashing, and my cable modem works great on my other computer. I opened Xterminal and verified my setup.

This is what I get with lspci

Code Sample

0000:00:00.0 Host Bridge: Toshiba America Info Systems 601
0000:00:02.0 CardBus bridge: Toshiba America I.S. ToPIC95
0000:00:02.1 CardBus bridge: Toshiba America I.S. ToPIC95
0000:00:0b.0 USB Controller: NEC Corp. USB
0000:15:00.0 Ethernet controller: D-Link DFE-690TXD CardBus PC Card

Okay, it sees my card (great!). Now here's what I get with ifconfig:

Code Sample

eth() Link encap:Ethernet HWaddr 00:0D:88:3E:26:F6

I even recycled my modem (unplugging, then plugging back in). I still can't figure out why I can't connect, plus I'm out of ideas (even after Googling for the answer for 2 days). Anybody got any ideas?

Okay, I think this is a DNS issue. I suddenly got the idea to run the laptop through an old router I had lying around and used netconfig to send a dhcp broadcast to that same router. After a successful attempt I was finally able to to connect; this leads me to believe thath the system was having problems resolving DNS queries - using a router took that responsibility from the computer.

My only question now is, what should I do to enable the computer itself to resolve DNS without the router?
