[Bug 578244] [NEW] Sometimes ar9170usb based card disconnect and lock

Mon May 10 13:11:16 UTC 2010

Public bug reported:

Sometimes my Atheros based USB wireless card disconnect from the access
point. All another cards (like card of my laptop) connected don't
disconnect. For reconnect I must disconnect USB card and reconnect.
There aren't any other method for connect. Seems hardware locked.

I remember that this did not happen before Karmic.

USB card:
0846:9001 NetGear, Inc. WN111(v2) RangeMax Next Wireless [Atheros AR9001U-(2)NG])

This is the time line of commands and kernel logs.

Here at disconnect.
