Hi,
I have two cards using the atheros chipset. However, setting up one
as access point and the other as client only yields a connection when
I enforce 11b mode on both cards.
I am using a 3.8 GENERIC kernel (dated 27 Oct):
OpenBSD 3.8 (GENERIC) #1: Thu Oct 27 18:22:38 CEST 2005
It detects the ath card on both machines:
ath0 at pci0 dev 14 function 0 "Atheros AR5212" rev 0x01: irq 11
ath0: AR5212 5.9 phy 4.3 rf5112 3.6, FCC1A, address 00:0b:6b:36:fd:a6
ath0 at pci0 dev 14 function 0 "Atheros AR5212" rev 0x01: irq 11
ath0: AR5212 5.9 phy 4.3 rf5112 3.6, FCC1A, address 00:0b:6b:36:fe:43
I then clear the ath card settings as indicated in the man page:
ifconfig ath0 -bssid -chan media autoselect nwid "" -nwkey -powersave
down
I set up the hostap with:
ifconfig ath0 10.4.0.1 netmask 0xff000000 media autoselect mode 11a
mediaopt hostap nwid foo nwkey bar up
ifconfig shows that the hostap is running:
ath0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST>
mtu 1500
lladdr 00:0b:6b:36:fd:a6
media: IEEE802.11 autoselect mode 11a hostap
status: active
ieee80211: nwid foo chan 36 bssid 00:0b:6b:36:fd:a6 nwkey bar
inet6 fe80::20b:6bff:fe36:fda6%ath0 prefixlen 64 scopeid 0x2
inet 10.4.0.1 netmask 0xff000000 broadcast 10.255.255.255
I start the client with:
ifconfig ath0 10.4.0.2 netmask 0xff000000 media autoselect mode 11a
nwid foo nwkey bar up
but it does not find any network (I let it wait awhile to do some
scanning):
ath0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST>
mtu 1500
lladdr 00:0b:6b:36:fe:43
media: IEEE802.11 autoselect mode 11a (OFDM6 mode 11a)
status: no network
ieee80211: nwid foo nwkey bar
inet6 fe80::20b:6bff:fe36:fe43%ath0 prefixlen 64 scopeid 0x2
inet 10.4.0.2 netmask 0xff000000 broadcast 10.255.255.255
Same story with enforced mode 11g
However setting mode "11b" in the same command line as above
immediately yields a connection on the client:
ath0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST>
mtu 1500
lladdr 00:0b:6b:36:fe:43
media: IEEE802.11 autoselect mode 11b (DS11 mode 11b)
status: active
ieee80211: nwid foo chan 1 bssid 00:0b:6b:36:fd:a6 nwkey bar
inet6 fe80::20b:6bff:fe36:fe43%ath0 prefixlen 64 scopeid 0x2
inet 10.4.0.2 netmask 0xff000000 broadcast 10.255.255.255
Not setting any mode at all starts the hostap in 11a mode and the
client is not able to connect as well.
Note: The boxes are standing right next to each other. I tried it in
several buildings so I do not think that this might be due to
interference.
I wonder if this is a driver issue? Or could it be a problem with the
hardware?
Thanks a lot,
Robert
