Hello.
I have a problem that is very similar to already reported in ticket #287 by erik.tews at gmail.com. But as this is another issue not related to that ticket I opened a new one.
I'm trying to connect two coomputers with adhoc network. I'm using the following commands:
# modprobe ath_pci autocreate=none
# wlanconfig ath0 create wlandev wifi0 wlanmode adhoc
# iwconfig ath0 essid "hn" key open 1234-1234-65
# ip addr add 192.168.0.3/24 brd + dev ath0
# ip link set dev ath0 up
After this wireless connection works for three seconds or so (I'm pinging the other end and only three pings pass), after that I receive a message in kernel log
ath_rate_sample: no rates for 00:05:4e:4b:09:2d?
And connection stops. I've tryied to play with channels on both ends, but still no luck. I've tryed to change rate_sample on rate_amrr, but then connection dies without any kernel message. I have this problem with madwifi-ng-0.9.2 and madwifi-ng-0.9.1, but I do not have such problem with madwifi-ng-0.0.1531.20060427.
I have built in wifi card in thinkpad T41 notebook:
02:02.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)
And seems that it is important (this drivers versions worked with some wireless access point) another end of connection is windows XP with "LNW 802.11g Wireless USB Card LSC-710".
Are there any ideas what can be done?
TIA
