Newbie help with networking

Hi,

I am new to Linux, esp to LiveCD. It seems like a wonderful thing, if only I
can get the network going!

I am trying to work from a laptop with broken HDD. I am using a PCLinuxOS
LiveCD. I am using a DWL-G650 D-Link pcmcia card.

I could use the configurator to set up the SSID, WEP, et al for the card and
it seems to connect (status lights blinking). However, I am unable to reach
anywhere! I tried the following to set up the IP address, etc:

ifconfig ath0 192.168.0.201 netmask 255.255.255.0 up

It seems to work fine, and when I do a ifconfig ath0, I see the assigned IP
as in my command. However, ping 192.168.0.1 fails (Destination Host
Unreachable). Not surprisingly, it also fails for ping www.yahoo.com
(unknown host ...).

I have included the following in /etc/resolv.conf, but it did not make any
difference!
domain cfl.rr.com
nameserver 192.168.0.1

Any help would be appreciated.
Thanks
SB

You need to define a gateway too whit route, see the man page for details.

Yeah because the J.O. Aho was so kind to not tell you how to add a
default gatway i will tell you.
route add default gw 192.168.0.1

providing 192.168.0.1 is your gateway
your gateway is the actual machine/router that has the internet access.

The route command requires that you at least have a static connectivity to
the gateway. In this case, please note that ping 192.168.0.1 does not work!
That is the router for me.

Any other suggestions?

Thanks!

That is not true, if by "static connectivity" you mean "not dhcp".
It is perfectly possible - in fact normal, I would have thought -
for the gateway to be at the other end of a dhcp connection.

I haven't followed the thread, but would suggest trying something like

route add -net 192.168.0.0 netmask 255.255.255.0 dev ath0
route add default gw 192.168.0.1
