Comment 1 for bug 137565

I can confirm this on an Asus G1S. I have to take exactly the same steps to resurrect the Internet connection.

I also get the symptom that when the connection goes down, an "iwlist scan" hangs for a few seconds, and then responds with the error "resource temporarily unavailable." Furthermore, an "iwconfig wlan0 essid <name>" has no effect and does not show the access point as associated on a subsequent "iwconfig"

This problem does not occur on every wireless network - the frequency of the problem seems to be highly dependent on how many networks are available, and on the particular make and model of the AP's hardware. I have been able to run a flawless connection for five hours on some networks, and on others I barely can stay connected for five minutes.

I can say, though, that running NetworkManager increases the likelihood of this happening. Any ideas on how we might be able to make progress toward identifying what exactly goes wrong?
