It prints:

It prints:

run_newassoc: new assoc isnew=1 associd=c001 addr=00:26:bb:17:f6:61
...
run_newassoc: rate=2, mgmt_ridx=0

> If not, I need to fix the driver. If things go accordingly, please compare the mode. With your config, group key uses TKIP (mode 3) and pairwise key uses CCMP (mode 4). And very first arp who-has packet uses group key and other use pairwise key. Maybe, macbook doesn't like mixing the mode. So, please

Strange, looks like this time works as expected, but sometimes it
doesn't work.

In some cases it doesn't work and you can find complete tcpdump output
from very beginning to the modem hang:

http://pastebin.com/1ALmV7mA


> and check if any packet with address of all 'ff'. is sent/received alright. All 'ff 'means using group key. Others use pairwise key. All 'ff  is easy to see in output of tcpdump. Or, you can chose one of them, CCMP or TKIP for 'wpa_pairwise=' and see if it makes any difference.

Will test it and let you know.
