Hi all! I tried to use CentOS5 on an IBM Thinkpad R52 which has an Intel PRO/Wireless 2915ABG Mini-PCI Adapter installed. I downloaded the firmware from the DAG-Repo (afaik 3.0.0) and added a "alias eth1 ipw2200" to modules.conf. After the module was loaded successfully (including the firmware) I was able to configure the card. For simplicity I didn't use any encryption. My access point as well is not using any encryption. I tried to use DHCP, but the card didn't get assigned to any IP address. So I used the manual configuration which seemed to work fine during startup. But unfortunately not network connection could be made. So no ICMP ping packets where reaching the destination. Using the iwconfig command I could see my SSID from the access point. Playing around with some values didn't have any success. So I tried using FC8- and it worked fine with fixed address settings. As well as OpenSuSE 10.2. Anyone an idea what's going wrong here?

Can you try to install a FC8 kernel, if you don't suffer dependency problem ? (or with a FC7 kernel) If static IP is working, are you sure your DHCP is working on the wireless side ?

After your interface starts, check to see if dhclient is running. It seems that for some reason, even though I have BOOTPROTO=dhcp in the interface configuration file, it doesn't get an address, but if I run dhclient eth1 it gets an address immediately. I differ in the fact that I am using encryption, and am getting my feet wet with wpa_supplicant .. which could be part of my issue, as encryption would have to be finished setting up before I could use that link to get an address.
