Hello everyone. I have a AP with AR5413 with RouterOS and several OpenBSD clients. IBM notebooks using ath(4), iwi(4) and rum(4) work perfectly. The problem happens when I try to connect my alix board (4.7-release, i386) with Wistron Neweb CM9 (with unlocked all channels, cos we use 5500-5700 MHz):
- routerboard r52 or ubiquiti sr5 behave in similar fashion, but freeze the system after first ifconfig down & up (something wrong in the _reset_ function?) - ifconfig ath0 debug nwid test 10.10.89.2/24 up #typed right after boot => proceeds authentication but gets five association responses (+ Retry bit). WPA on: ends up in a loop, where the first EAPOL packet from the AP is received about 15 times, regardless of a response already sent - the console says "receiving msg 1/4 of the 4-way handshake" and "sending msg 2/4 of the 4-way handshake" in a loop. After a minute, it gets a deauth and quits. Here's the thing recorded with tcpdump: http://sztorkie.steadynet.org/files/temp/tcpdump-atheros/cm9-wpa WPA off: seems connected, but no data gets through (at least icmp don't). http://sztorkie.steadynet.org/files/temp/tcpdump-atheros/cm9-nowpa - ifconfig ath0 down && ifconfig ath0 up #after that => doesn't even connect. Ends in an infinite loop "sending auth", then actively probing all channels and "sending auth" again (tcpdump shows the first 802.11 authentication packet) without any response from AP (something wrong in the _reset_ function?) - sometimes the cm9 sends Probe Request on channel + or -1 than the real one, *and it gets response* even if the ap is on different freq! Does anyone have a clue what could cause such weird behavior for CM9's? I know that RouterOS's network practicies sucks, but why do IBM cards work well? -- Martin Pelikan PS: Oh, and I tried three of them. And the signal is good.
