This looks like an admtek card. Is it? in other words what driver module is loaded for it? use lsmod to see. Is this pci or cardbus or usb? Also, what kernel version is running?

It is prism and all the modules are loaded.

I did ifconfig wlan0 192.168.0.108 up
and it displays the ip addres Bcast 192.168.0.255 and netmask 255.255.255.0.
I am getting reply from 192.168.0.1 when I ping. I guess this is the ip adress of my router (D-Link router with DSL connection at home)
Also I am getting reply from the other computer on the lan 192.168.0.105 but with www.google.com it says unknown host

check your /etc/resolv.conf file, it should have a line like this:
nameserver 192.168.0.1

resolve.conf is empty. Shoud I directly write this line into it? Or do I need anything else, any script...

no that line should do it, and no need to reboot or restart anything either. of course the file in question is resolv.conf, not resolve.conf.

Hi akaBeaVis,
After entering nameserver into resolve.conf it is able to locate the ipaddress. When I run ping www.google.com, it says...
PING www.google.akadns.net (216.239.37.99): 56 octets data
sendto: Network is unreachable
ping: sent 64 octets to www.google.akadns.net, ret=-1
sendto: Network is unreachable
--- www.google.akadns.net ping statistics ---
2 packets transmitted, 0 packets received, 100% packet loss

route -FC shows Gateway as 192.168.0.1 I am still missing something.

sounds like maybe your router settings are such that this card is not allowed out of the localnet. also, what does the log say when you try to ping?

one more thing, is this the linux-wlan-ng driver? if so, it has it's own proprietary control program which you use in place of iwconfig, I think it's wlanctl-ng. I don't own any prism devices (yet) so I'm kinda foggy on that.

The same card used to work with the same router with red hat and windows. What is the location of the log file?
Thanks

Ah, well that is different then, unless you've changed something on the router it's probably not worth bothering with, but I would check /var/log/messages starting from the the end and working back, there might be a clue in there. Obviously something is blocking you from reaching beyond the local network, you can get dns, but nothing more, maybe some security settings and/or iptables stuff in vector?

Hey akaBeaVis!
I finally did it. I don't know how, but adding nameserver to resolv.conf ip address and default gateway to the routing table. I really thank you for all your help. It helped me a lot and got something to learn.

Thanks again buddy
