Hello,

So, I just installed the madwifi software for my D-link G650 wireless card. I am using the GUI network configuration tool on Fedora Core 4 to configure the wireless card. I don't know how to use anything else. The card connects to the wireless network immediately and even get an IP address. The problem is that it doesn't get the DNS address. So, I can go to a website with another IP address, but not with a domain name. I've tried putting the DNS server address in the Netowrk Configuration tool manually, but that doesn't seem to work either. What do I do???? My network card has no problem getting the DNS address on the same network. I've tried multiple networks.

Can you access a website with an ethernet card without specifying its IP address?

It could be a problem with DNS resolution not the wireless network card.

No. I cannot access a website without specifying its IP address. I'm assuming it is a problem with the DNS resolution. How do I fix it?

I'm a little unclear about your network setup. Do other PC's resolve IP addresses ok? If so it is a problem with the DNS configuration on that computer you are using the wireless card on.
edit /etc/resolv.conf and add appropriate DNS entries. In Australia they might look something like this.

nameserver 210.15.254.230
nameserver 210.15.254.240
search mydomain.org

for example as the DNS addresses of your IP provider.
You may need to update the system by rebooting to recognise the changes, or run some update script. I use SuSE and am not really familiar with Fedora.

If you are running a DNS server you put instead the IP address of the network DNS server.

If you have a proxy server, it resolves addresses with the IP provider or using a DNS server, and you point your browser at it under 'Connection Settings' for example
192.168.1.1 or similar port 3128 or 8080.

Let me know how you go
