New description:
I'm using Debian Sid with the new 2.6.24 kernel (and the version of ath5k
included in this kernel).
I switched to ath5k because the madwifi driver I was using before does not
compile at the moment (at least the version included in Debian - the
maintainer is working on that afaik). So I decided to give ath5k a try.
Sadly it is not working as expected: I suffer from permanent network
interrupts (about 30-60 seconds connection and then about 1 to 3 minutes
no connection).
I use wpa_supplicant, changed to wext and otherwise used the very same
(known good) configuration. I get the following in dmesg:
{{{
ath0: Initial auth_alg=0
ath0: authenticate with AP <MAC-ADDR-OF-AP>
ath0: RX authentication from <MAC-ADDR-OF-AP> (alg=0 transaction=2
status=0)
ath0: authenticated
ath0: associate with AP <MAC-ADDR-OF-AP>
ath0: RX ReassocResp from <MAC-ADDR-OF-AP> (capab=0x411 status=0 aid=1)
ath0: associated
ath0: switched to short barker preamble (BSSID=<MAC-ADDR-OF-AP>)
ath0: invalid Michael MIC in data frame from <MAC-ADDR-OF-GW>
[about 6 of those messages skipped]
ath0: invalid Michael MIC in data frame from <MAC-ADDR-OF-GW>
ath0: RX deauthentication from <MAC-ADDR-OF-AP> (reason=14)
ath0: deauthenticated
}}}
=> now I am offline.
{{{
ath0: RX deauthentication from <MAC-ADDR-OF-AP> (reason=7)
ath0: deauthenticate(reason=14)
[5 msgs skipped]
ath0: deauthenticate(reason=14)
}}}
=> after some time it is able to connect again:
{{{
ath0: authenticate with AP <MAC-ADDR-OF-AP>
ath0: RX authentication from <MAC-ADDR-OF-AP> (alg=0 transaction=2
status=0)
ath0: authenticated
}}}
=> then the same game starts again:
{{{
ath0: authenticate with AP <MAC-ADDR-OF-AP>
ath0: RX authentication from <MAC-ADDR-OF-AP> (alg=0 transaction=2
status=0)
ath0: authenticated
ath0: associate with AP <MAC-ADDR-OF-AP>
ath0: RX ReassocResp from <MAC-ADDR-OF-AP> (capab=0x411 status=12 aid=0)
ath0: AP denied association (code=12)
ath0: associate with AP <MAC-ADDR-OF-AP>
ath0: RX AssocResp from <MAC-ADDR-OF-AP> (capab=0x411 status=12 aid=0)
ath0: AP denied association (code=12)
ath0: associate with AP <MAC-ADDR-OF-AP>
ath0: RX AssocResp from <MAC-ADDR-OF-AP> (capab=0x411 status=12 aid=0)
ath0: AP denied association (code=12)
ath0: association with AP <MAC-ADDR-OF-AP> timed out
ath0: Initial auth_alg=0
ath0: authenticate with AP <MAC-ADDR-OF-AP>
ath0: RX authentication from <MAC-ADDR-OF-AP> (alg=0 transaction=2
status=0)
ath0: authenticated
ath0: associate with AP <MAC-ADDR-OF-AP>
ath0: RX AssocResp from <MAC-ADDR-OF-AP> (capab=0x411 status=0 aid=1)
ath0: associated
ath0: switched to short barker preamble (BSSID=<MAC-ADDR-OF-AP>)
}}}
=> after some time it is switching to "short baker preamble" for me that
means I stay online a little longer, sometimes even 60 seconds. But then
it starts
with invalid Michael MICs again (20 or more most of the time):
{{{
ath0: invalid Michael MIC in data frame from <MAC-ADDR-OF-GW>
}}}
then I get lots of "ath0: deauthenticate(reason=14)" with some of those
inbetween:
{{{
ath0: RX deauthentication from <MAC-ADDR-OF-AP> (reason=7)
ath0: deauthenticated
}}}
If you need any more information or would like me to help with debugging
or trying out newer versions just let me know!
