[SOLVED] Need help configuring network adapter

paladin7721 · 01-31-2010, 01:14 PM

I've only been using linux for a few days so I don't know all the tricks. I'm pretty savy configuring windows networks however.

My adapter is (according to windows) a: CNet PRO200WL PCI fast ethernet adapter

Linux says it is a: 21x4x DEC-tulip compatible 10/100 Ethernet

I do seem to be getting an ip address from the DHCP router, but I cannout ping any other ips or connect to the internet.

I've tried a bunch of different options, switching things back and forth, but it still doesn't work, and honestly i don't even know what some of the options mean.

Any help or tips in correctly configuring my adapter would be appreciated!

ALSO, if this helps:
paladin:~ # ifconfig eth0
Eth0 Link encap:Ethernet HWaddr 00:08:A1:03:3C:99
inet addr:192.168.1.5 Bcast:192.168.1.1255 Mask:255.255.2255.0

Try to:

ping 208.67.222.222

Tell if it will go or not.

You need to add your default gateway

Code:

route add default gw xxx.xxx.xxx.xxx

Have you connected ethernet cable from your computer to somewhere? If yes, what is it?

Is your ip still 192.168.1.5 ?
since you changed it

Yes, my ethernet cable is connected to a Linksys Router (WRT54G) with the routing functions turned off, just using it as a switch. The linksys router is connected to a Verizon FiOS router which is set up as the DHCP router for the network.

I can boot to Windows and the internet, and networking between my other computer works fine, so I know that the connections are all good.

nimnull22 · 01-31-2010, 03:15 PM

Can you try to do:
ping -b 255.255.255.255

Post output, please.

No it was changed. I changed it back to 192.168.1.1 and re-entered the command:

Code:

# route add default gw 192.168.1.1

There was no output, so I typed # route -n and got this:
