A happy new year to all,
I have a Netgear wireless router and three Linux boxes: One with a
DWL-AG650 and two with WG311Ts. For some time it works fine but
sometimes one of the boxes loses its connection. Then the affected card
shows something like the following:
ath0 IEEE 802.11g ESSID:"matrix2"
Mode:Managed Frequency:2.417 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=24/94 Signal level=-71 dBm Noise level=-95 dBm
Rx invalid nwid:17004 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
I have no explanation why it is showing a good link quality without
being associated to an access point. Also the frequency should be 2.437
Ghz. Sometimes all three card do that within a short period of time.
I am using WPA for encryption with madwifi and wpa_supplicant:
[EMAIL PROTECTED]:~# cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
ap_scan=2
fast_reauth=1
network={
ssid="Isestrasse69"
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP CCMP
psk=01107b66e19be999f93f9937961f84c0548de5ad047743b0b4396047e4c44367
scan_ssid=1
#psk=’assuppavedrano9’ # siehe unten
}
Without any encryption it seems to be working fine. I haven't tried WEP
yet but I would rather use WPA as the router cannot use WEP in 802.11n
mode. There is another wireless network in the neighborhood, but on a
different channel. I have already tried a different access point (also
Netgear), but without any improvement. The two boxes with the
Netgear-cards have Ubuntu on them, the other one is a laptop with
Gentoo/amd64.
Greetings,

Hi Robert
Try
pairwise=TKIP CCMP
groupwise=TKIP CCMP
Or better still only use CCMP (AES encryption) if you can. TKIP was a
stopgap solution to fix WEP while CCMP was being developed.

ps: You better change your psk now it has been advertised to the whole
world.
