I have purchased 4 of these devices about 2 months ago and have experienced all of the issues reported within this thread. The came with the 184.108.40.206 FW rev installed, so unless the 220.127.116.11 on the cisco DL site is different, nothing I can do with that.
I've tried making them work as stand alone AP's, Bridge<->Bridge, etc... all modes seem to lock up eventually needing a reboot to get any functionality back.
Ultimately, I need to make them work in AP<->Client-Repeater mode. I've not been successful in making them work in any mode for a prolonged period of time.
having just rfound this thread today, I have not tried hard coding the NIC's to 100/full, but will give it a try. If it works, great, but then that would defeat the purpose of buying an N radio AP. I would like the potential 300Mbps throughput.
Any update from Cisco on this? Help!!!
