Wireless laptop sees router but can't ping anything


This is really weird and its starting to bug me. I just installed Slackware 10 and it has found my pcmcia card and my wireless network. It has picked up the ESSID and the mac address of the AP.

Here is part of my iwconfig.
Code:
eth1    IEEE 802.11-DS ESSID:"penguin" Nickname:"darin3200"
Mode:Managed Frequency:2.422GHz Acess Point: 00:06:25:BA:EC:AD
Bit Rate:11Mb/s Tx-Power=15dBm Sensitivity:1/3
My ifconfig gives me only eth1 (wireless) and lo. Whenever I try to ping anyplace I get "Connect: Network is unreachable" I have also checked my router's dhcp clients and my laptop isn't listed.
Any ideas?
Thanks

if you run /sbin/ifconfig on your terminal command line, does eth1 have an IP address?

to see ALL of the interfaces on your system, use /sbin/ifconfig -a to show ALL of the interfaces that are avalible on the system. just running /sbin/ifconfig without any extra flags will just show you the configured interfaces.

you may have to assign a static IP to the interface using [as root]:
Code:
[root@c0re config]# ifconfig ethN [ your_ip ]
[root@c0re config]# route add default gw [ your_gateway_ip ]
OR to assign a dhcp ip
Code:
[root@c0re config]# dhcpcd -k -d ethN
[[ N is the number of your network interface. ]]

the route commad allows you to assign or show network information. to check and see if route has properly entered your gateway [router] into your routing table, just run 'route' on a command line. it should give you some output that looks kind of like this.
Code:
[root@c0re config]$ route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
127.0.0.0       *               255.0.0.0       U     0      0        0 lo
default         router          0.0.0.0         UG    0      0        0 eth0
you can see the default route in the last line. my router has an assigned hostname of 'router' im my /etc/hosts file, so you see its name come up as opposed to the IP.

for dhcpcd...
-k -- kills any previous dhcpcd processes, just in case its already running
-d -- kicks dhcpcd into verbose mode, so you can see whats going on. just in case your box is having problems talking to your router.

you might want to post the output from an ifconfig and ifconfig -a and a route command. just so we can see it. we might be able to give you some more help that way.

'dhcpdcd -d eth1' did the trick Now I can surf lq from my laptop I'm suprised it didn't run dhcpdcd at boot time.

Thanks for the help

no problem.

if you want to run dhcpcd on boot, you can always look into editing the file /etc/rc.local [i think its called something else in gentoo!!] to tell the card to run dhcpcd on boot.

I'm using an IBM T-21 (800mhz P3, 256mb ram, 20 gig hd) with an orinoco card. I'm suprised how much better reception I get with an orinoco card compared to a linksys.
