 |

Hi!
I have set up an airport extreme card with wpa-supplicant on a PowerBook. The card works and I can connect to the access Point (Airport Express Base Station). The problem now is that every few seconds the Machine reconnects to the access Point. This is a big problem since network shares are getting totally useless because of beeing unmounted and remounted a million times a day. Also browsing the web is quite painfull because every 3rd site has to be reloaded a few times before it can be displayed. Don't think about network games...
OK. Here's the dmesg log: | Code: | SoftMAC: Authentication response received from 00:17:ab:c9:15:de but no queue item exists.
SoftMAC: Authentication response received from 00:14:51:6a:77:6c but no queue item exists.
bcm43xx: set security called, .enabled = 0, .encrypt = 0
bcm43xx: set security called, .enabled = 0, .encrypt = 0
bcm43xx: set security called, .level = 0, .enabled = 0, .encrypt = 0
bcm43xx: set security called, .level = 0, .enabled = 0, .encrypt = 0
bcm43xx: set security called, .level = 0, .enabled = 0, .encrypt = 0
SoftMAC: Open Authentication completed with 00:14:51:6a:77:6c
bcm43xx: set security called, .active_key = 0, .level = 2, .enabled = 1, .encrypt = 1

This is the part printed out during 1 reconnect cycle. You can immagine how often this block is repeated in my dmesg. The strange thing is that I don't own any hardware with the HWAddr 00:17:ab:c9:15:de. Also iwlist scan doesn't return any Access point with this address. So why do I get an Authentication response from it even if no request was sent?
The second HWAddr is the one from my access point.
Sometimes I also get also this messages: | Code: | TKIP: replay detected: STA=00:14:51:6a:77:6c previous TSC 00000000003d received TSC 00000000003d
TKIP: replay detected: STA=00:14:51:6a:77:6c previous TSC 000000000050 received TSC 000000000050
TKIP: replay detected: STA=00:14:51:6a:77:6c previous TSC 00000000005d received TSC 00000000005d
TKIP: replay detected: STA=00:14:51:6a:77:6c previous TSC 00000000005d received TSC 00000000005d
TKIP: replay detected: STA=00:14:51:6a:77:6c previous TSC 000000000063 received TSC 000000000063
TKIP: replay detected: STA=00:14:51:6a:77:6c previous TSC 000000000063 received TSC 000000000063
TKIP: replay detected: STA=00:14:51:6a:77:6c previous TSC 00000000006b received TSC 00000000006b |
Note that I don't have this problem with Mac OS X. Also a friend of mine with an ipw2100 card doesn't have this problem on my access point and I do NOT have the problem with his access point. So it seems to be a problem with my configuration in combination with this access point.
Useful info:
| Code: | uname -r
2.6.19-gentoo-r5
|
with loaded bcm43xx module and the crypto modules.
/etc/wpa_supplicant/wpa_supplicant.conf: | Code: | ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
fast_reauth=0
network={
ssid="mynet"
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
psk=secretpasskeyinhex
priority=1
}

Could anyone point me to the right direction how to make my wireless connection more stable?
Drop me a note if you need other configs but I think it's enough for this post
