Orinoco Wifi Card
 
Hey guys,

I have a proxim orinoco gold card and I want to use it on campus with my campus wide wifi network. I'm using Suse Linux 9.2 and it detected it and all. I setup encryption and set it to be dhcp etc.

The really weird thing is it pulls and IP address from the dhcp server but I cannot access any network/internet resources. I know the card/signal are fine because I am using it right now under windows.

I was wondering if anyone could give me any ideas on a fix or how to troubleshoot this. I'm realtively new to linux and troubleshooting tends to be a bit difficult.

The only other info I can say is that when I use YAST to configure the wifi card by clicking "change" is that I set the hostname to "tuxbox" and I leave the domain name blank since it changes between my home/school network. I aslo have the "change hostname via DHCP" unchecked. When I click ok it says that there was an error. Maybe this is my problem, but I am unsure.

Any guidance would be of great help....Thanks again, it is much appreciated.

Check with campus services dude. Most likely you will need to access using a proxy server - they will have the address and port (if necessary) as uni's dont generally tend to allow complete network access.

Thanks snecklifter but I didn't have to configure anything for windows and DHCP only the encryption key and the network ssid. Any other shots in the dark.

Ah okay. Try some stuff in this order.
ping 127.0.0.1
ping localhost
If both of these are okay then run
route
or
ifconfig
and ping the ip address dhcp has assigned your computer.
If all of this works (okay I know its a b***-ache but it helps) then post back the iwconfig and ifconfig outputs as well as route output and I'll have another look.
Regards
Chris

Well, it means that your TCP/IP stack is functioning fine and you've got an IP address no probs using DHCP. The problem I think you have is that you do not have a gateway IP in your routing table. This is basically the IP address of the AP that assigned your IP address and will handle DNS and other such. For example, my routing table:
Code:

[chris@snecklifter ~]$ route
Kernel IP routing table
Destination    Gateway        Genmask        Flags Metric Ref    Use Iface
192.168.2.0    *              255.255.255.0  U    0      0        0 eth1
169.254.0.0    *              255.255.0.0    U    0      0        0 eth1
default        192.168.2.1    0.0.0.0        UG    0      0        0 eth1

whereas yours is
Code:

144.118.xx.x * 255.255.248.0 U 0 0 0 eth1

link-local * 255.255.0.0 U 0 0 0 eth1

loopback * 255.0.0.0 U 0 0 0 lo

Your computer doesn't know where to go next basically. You'll notice there is no "UG" route. I'm not sure why as this process is usually all automated - you dont really need to know all this. I'm not experienced enough to tell you how to fix this im afraid. I suggest you check the man pages
Code:

man route
and see if they help at all or contact campus network services.
Good luck.
Chris

As a footnote, I would however try disabling eth0 with
Code:

ifconfig eth0 down
and then renew your ip
Code:

dhclient eth1
and see if your wired interface isnt causing grief.

route add default gw 192.168.0.1

Just change the IP to your known gateway, and run it. (You must be root)
