I just bought a Netgear WAG511 card and a Netgear WG602 Accesspoint. I run the card in 11g mode under current, and I'm having some problems:
*) Powersavemode seems to be not supported at all (and thus it eats the battery like a "make world"):
# ifconfig ath0 powersave on ifconfig: SIOCS80211: Invalid argument
man ath(4)
*) Shared Key Authentication seems to be not supported either:
# ifconfig ath0 authmode shared ifconfig: SIOCS80211: Invalid argument
Never has been supported under FreeBSD for any 802.11 card (at least not that I'm aware of).
*) If I turn on the debug.ieee80211 sysctl, I see the following messages in 30sec- to 2min-intervals:
ieee80211_new_state: RUN -> AUTH ieee80211_new_state: AUTH -> AUTH ieee80211_new_state: AUTH -> ASSOC ieee80211_new_state: ASSOC -> RUN
(I'm not sure if this is normal behaviour.)
Not sure about the interval but it is normal for an AP to periodically require stations to reauthenticate/associate.
*) I'm seeing a lot of input errors on the interface:
# netstat -i -I ath0 Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll ath0 1500 <Link#3> 00:09:5b:41:8d:ac 2054 67646 2058 42 0
*) Finally, there seems to be a problem with interaction between the AP and my ADSL router (I'm not sure if this is a FreeBSD problem, I need to test with WinXP too). My LAN looks something like this:
WLAN Client ))) ((( AP --- Switch --- ADSL router | | other hosts in LAN
The ADSL router (a Speedtouch 510) does NAT. Everything seems to work fine, but after some time, all connections from the WLAN client to the outside world have died. I can connect to the other hosts in the LAN just fine, though, and there are no further messages in the log files. The quickest way to make it work again, is pulling the card out and plug it back it. Any ideas?
If I understand correctly, it doesn't sound like something to do with the driver which is all I can control. I'd suggest sniffing the 802.11 frames to see if you can identify anything. If you have another system+card you can do this with something like:
tcpdump -i ath0 -y IEEE802_11
or use your favorite tool.
