I have a ASUS WL500-W router running stock Backfire 10.03 whose
(broadcom) wireless card was replaced with a Atheros 5416 card
(kmod-madwifi installed) because I thought it was better supported. My
/etc/config/wireless file look like this:
config 'wifi-device' 'wifi0'
option 'type' 'atheros'
option 'channel' '7'
option 'diversity' '0'
config 'wifi-iface'
option 'device' 'wifi0'
option 'mode' 'ap'
option 'network' 'wifi'
option 'ssid' 'Moonbase'
# option 'encryption' 'psk2'
option 'encryption' 'psk2-aes'
option 'key' 'lame passphrase here'
option 'eap_type' 'TLS'
Here are some things I have noticed:
1) I am seeing a lot of "stuck beacon" messages in dmesg:
wifi0: ath_bstuck_tasklet: Stuck beacon; resetting (beacon miss count: 11)
wifi0: ath_bstuck_tasklet: Stuck beacon; resetting (beacon miss count: 11)
wifi0: ath_bstuck_tasklet: Stuck beacon; resetting (beacon miss count: 11)
wifi0: ath_bstuck_tasklet: Stuck beacon; resetting (beacon miss count: 11)
wifi0: ath_bstuck_tasklet: Stuck beacon; resetting (beacon miss count: 11)
[...]
At the same time, the wireless connection seems to fluctuate between
nice and responsive to quite sluggish. By that I mean it feels like it
is timing out a lot or it has no connection but the connection itself
never drops. For instance ping times between my laptop and router or a
machine in the wired side will increase hundredfold (2ms to 200ms). If I
manage to go to the router and issue a 'wifi up' command, the wireless
will become fast once again.
Googling around I found pages such as
http://spod.cx/blog/debian_lenny_madwifi_hostapd_stability_issues.shtml
and http://madwifi-project.org/wiki/StuckBeacon stating it might be a
problem with madwifi itself. Can anybody confirm or deny that? If the
latter, what else can be causing these issues?
