So far, it's impossible to tell what's actually going on when you see the problem. Here's a few question that might or might not help with narrowing it down: Does 'ifconfig iwx0 debug' write anything to dmesg while it hangs? Does it occur on 2 or 5 GHz channels only? Is it specific to 11n mode or also 11a/g? Are the any settings in the access point's configuration UI that make a difference? Is the problem related to raoming, as in, if your AP offers the same ESSID on multiple channels, does it "help" if you configure a unique ESSID per frequency band/channel? Do you see traffic passing in tcpdump -D in -i iwx0 -y IEEE802_11_RADIO? Do you see corresponding traffic passing in tcpdump -D in -i iwx0? Do any of the counters shown by netstat -W iwx0 behave differently while the problem occurs? Do these counters perhaps indicate dropped packets, e.g. due to decryption failures? It's unlikely that the driver could only be unwedged by rebooting the system. Most likely it implies you simply haven't yet found out what exactly needs to be done to unwedge it. Can you find a way?
