Unable to get IP Address with ipw2200 and wpa_supplicant

Crushing Belial · 02-12-2007, 09:27 PM

Running Slackware 11, with the Intel 2915 chipset, and I can't seem to get my laptop to connect to my WPA-enabled network. When I run "wpa_supplicant -ieth1 -Dwext -c /etc/wpa_supplicant -dd -B", everything appears to be ok, but I can't connect. It just hangs on dhcpcd eth1 for a few minutes. I can connect to my network with dhcpcd with ethernet, and encryption turned off, but WPA doesn't want to work.

Code:

bash-3.1# wpa_supplicant -ieth1 -Dwext -c /etc/wpa_supplicant.conf -dd -B

Perhaps because of the '?' character in the SSID?
Try not to send wpa_supplicant into the background by removing the '-B' from your commandline, perhaps you'll find out some more by watching wpa_supplicant's actions after it finds the eth1 interface and starts doing it's work.

Ok, I'm using a custom kernel configuration that someone posted online who has the same laptop model as me (ThinkPad R52), and as it turns out, he didn't enable IEEE80211_CRYPT_TKIP, and IEEE80211_CRYPT_CCMP support into the kernel. I recompiled the kernel with support for WPA, and now it works fine. And for anyone else that has a ThinkPad R52, here's a really great kernel configuration file that is very clean and trimmed down. Only 1.4 MB after compiled. Just remember to enable those drivers in the kernel if you use WPA!

Oh, one more thing. There is a SlackBuild for the latest version of wpa_supplicant available here:
