[SOLVED] cannot connect to wireless network with wpa_supplic

Hello everybody,

I've seen posts related to my problem in the forum, but I still cannot establish a wireless connection.

I'm running Gentoo on an HP Pavilion dv2 notebook equipped with an AMD64 Neo processor. The wireless chip is a BroadComm BCM4322. I had to use the wl driver from BroadComm because the b43 driver does not support this chip yet, as documented at http://linuxwireless.org/en/users/Drivers/b43.

wpa_supplicant can properly use the driver to configure the interface:

Are you using MAC(not Apple MAC

)-based filtering rules?

Maybe off-topic, but shouldn't you post here the psk ?

I don't know what are filtering rules. Should they be part of the configuration file of wpa_supplicant?

The psk is shown in the config file.

Ok thanks for the replies, and sorry for my limited comprehension of the subject.

No, there's no filtering rules in the router. From the messages put out by wpa_supplicant, e.g. "ioctl[SIOCGIWSCAN]: Invalid argument", it looks to me like it could be a problem with the driver, or else some kind of incompatibility between wpa_supplicant and the driver.

I'll generate a new psk, even if the likelihood of somebody in my neighborhood reading this forum is very small.

Thanks again.

Victory!!

I was missing a module.

The README for driver wl from BroadCom says that the driver needs a security module, either lib80211 or ieee80211_crypt_tkip. I ran make menuconfig to have those built as modules. What was created is lib80211_crypt_tkip.ko, but looking at the source code of the driver, this is what it's looking for for kernel version >= 2.6.29.

It now works. wpa_supplicant can associate with the access point and dhcpcd assigns an IP address to the network interface, eth1.

Thanks anyway for the help.

I had a similar problem (i.e. wpa_supplicant was giving me "Invalid argument"). It looked like I needed CONFIG_LIB80211 and/or CONFIG_LIB80211_CRYPT_TKIP, but those weren't present when I did "make menuconfig" (kernel 3.10.x). It turned out that when I enabled CONFIG_HOSTAP, LIB80211 and its friends came along automatically. I thought HOSTAP was for making my laptop as an access point, but well, it works, so that's good enough for me.
