 Posted: Fri Feb 16, 2007 10:31 am Post subject: [solved] madwifi + wpa_supplicant + WPA2PSK + AES problems |
 |
|
First of all, sorry for the non-informative title, but since I'm not really sure what is working and what is not I don't know what else to put here.
The hardware:
Wireless router using WPA2PSK + AES encryption, using DHCP. Works with other gentoo-box (wireless with ralink-rt60 card) and this box using windows.
The card (works):
| Code: | 02:04.0 CardBus bridge: Texas Instruments PCI1510 PC card Cardbus Controller
03:00.0 Ethernet controller: Atheros Communications, Inc. AR5005G 802.11abg NIC (rev 01)
|
The software:
| Code: | [I--] [ ] net-wireless/wpa_supplicant-0.5.7
[I--] [ ] net-wireless/madwifi-ng-0.9.2.1
[I--] [ ] net-wireless/madwifi-ng-tools-0.9.2
[I--] [ ] sys-apps/pcmcia-cs-3.2.8-r2
[I--] [ ] sys-apps/pcmciautils-014-r1
[I--] [ ] virtual/pcmcia-2.6.13 |
The config:
| Code: | /etc/conf.d/net
modules=( "wpa_supplicant" "dhcpcd" )
config_eth0=( "dhcp" )
dhcpcd_eth0="-t 10"
wpa_supplicant_ath0="-Dmadwifi -d"
wpa_timeout_ath0=30
mode_ath0="managed"
config_ath0=( "dhcp" )
dhcpcd_ath0="-t 60"
|
| Code: | wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=1
network={
scan_ssid=1
ssid="xxxx"
proto=WPA2
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk="xxxxxxxxxxxxx"
priority=5
}
|
The output:
| Code: | /etc/init.d/net.ath0 start

All seems right, but no DHCP takes place  why not, it's listed in /etc/conf.d/net to a config via DHCP........
let's try it manually then:
| Code: | dhcpcd -t 60 ath0
Error, timed out waiting for a valid DHCP server response
|
looking at iwconfig:
| Code: | iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wifi0 no wireless extensions.
ath0 IEEE 802.11g ESSID:"xxxx" Nickname:""
Mode:Managed Frequency:2.427 GHz Access Point: Not-Associated
Bit Rate:54 Mb/s Tx-Power:18 dBm Sensitivity=0/3
Retry:off RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=47/94 Signal level=-48 dBm Noise level=-95 dBm
Rx invalid nwid:6849 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
|
encryption key: off?????
I found myself lost here, anyone who can help me out with this, or am I better off leaving my laptop wired for the rest of it's life?

Although it doesn't fit the Gentoo-filosophy, I've tried to use the Gnome NetworkManager (hardmasked). This tool makes config-files redundant.
When trying to connect using no encryption, this tool works flawlessly, but as soon as I activate any kind of protection (WEP, WPA, WPA2 or whatever else) it stops working.
The log of my router tells me this after failing:
| Code: | Saturday February 17, 2007 10:53:20 Associated: xx-xx-xx-xx-xx-xx st=0
Saturday February 17, 2007 10:53:24 Disassociated: xx-xx-xx-xx-xx-xx because WPA retey failed |
supposibly the "retey" should be "retry", is this my config or just the router? In Win32 this combination works fine, could there be an issue with the madwifi-ng driver?

it's working now, but not as I wished....
I had to set my router to accept both WPAPSK (TKIP) and WPA2PSK (AES) to get it to work, so all systems connect using WPA2PSK + AES and just this one using WPAPSK.....
My final configs:
| Code: | lsmod
wlan_scan_ap 6016 0
wlan_xauth 1920 0
wlan_tkip 12672 1
wlan_ccmp 8704 1
wlan_acl 4736 0
wlan_scan_sta 13568 1
ath_pci 90528 0
ath_rate_sample 15104 1 ath_pci
wlan 190812 9 wlan_scan_ap,wlan_xauth,wlan_tkip,wlan_ccmp,wlan_acl,wlan_scan_sta,ath_pci,ath_rate_sample
ath_hal 191696 3 ath_pci,ath_rate_sample
|
| Code: | wpa_supplicant
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
network={
ssid="xxxx"
key_mgmt=WPA-PSK
proto=RSN WPA
pairwise=CCMP TKIP
group=CCMP TKIP
scan_ssid=0
psk="XXXXXXXXXXXXXXXXXXXXXXXXXXX"
}
|
| Code: | /etc/conf.d/net
modules=( "wpa_supplicant" "dhcpcd" )
config_eth0=( "null" )
wpa_supplicant_ath0="-D madwifi -c /etc/wpa_supplicant/wpa_supplicant.conf"
config_ath0=( "dhcp" )
dhcpcd_ath0="-t 60" |
maybe it's just some issue/bug between the router firmware and the madwifi-ng driver, anyway, this can be considered working

consider this as being my weblog from now on 
for those of you who might use this as a reference in the future, wpa_supplicant works fine, the only thing that doesn't work is WPA2PSK (RSN in wpa_supplicant.conf) in combination with AES (CCMP).
It fails when performing the 4-way handshake, step 2/4, so maybe it's a bug in wpa_supplicant, I'll keep looking anyway, I refuse to give up safety for something like this
