I thought that if it made it into the kernel it would be alright to use. When I was downloading the rt2x00 from cvs it was a bit of a hit and miss affair. The rt2x00 driver works for some chipsets, but the rt2500usb doesn't seem to work at all. If you check the kernel config you may still see it marked as experimental. Better to use a CVS build (not in portage IIRC) of rt2570 and a current kernel than to try with rt2500usb at this time. That is what I am doing, with wpa using the iwpriv commands. -- gentoo-user@lists.gentoo.org mailing list
[gentoo-user] wpa_supplicant confusion
I am not sure I can explain this:
I can connect to an AP (using WEP), but only after I run
# iwconfig wlan0 ap auto
Within the next few seconds I get an IP via dhcpcd and I can immediately
connect to the Internet, but very unreliably. Within a few seconds it seems
that the link goes down, i.e. I can no longer ping Internet addresses, or the
AP, despite iwconfig showing that all is fine connection wise:
# iwconfig wlan0
wlan0 IEEE 802.11g ESSID:daddy
Mode:Managed Frequency:2.442 GHz Access Point: 00:18:4D:AE:55:2C
Bit Rate=12 Mb/s Tx-Power=27 dBm
Retry min limit:7 RTS thr:off Fragment thr=2346 B
Encryption key:8B7B-9671-89
Link Quality=31/100 Signal level=-56 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
wpa_cli also shows that the connection is OK:
status
bssid=00:18:4d:ae:55:2c
ssid=daddy
id=2
pairwise_cipher=WEP-40
group_cipher=WEP-40
key_mgmt=NONE
wpa_state=COMPLETED
ip_address=192.168.0.9
Ping-ing the AP has some ridiculous latency, or it fails completely:
$ ping -c 3 192.168.0.1
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

This is what's in the wpa_supplicant conf:
network={
ssid=daddy
bssid=00:18:4D:AE:55:2C
key_mgmt=NONE
# mode=managed
wep_key0=8B7B967189

# wep_key2=D3D68AA753
# wep_key3=35116656AB
wep_tx_keyidx=0

}
Any idea?

Also, WEP encryption is rather trivial to crack, especially so with a 40bit key. :p -- Regards, Mick signature.asc Description: This is a digitally signed message part.
