Re: Trying to understand a kernel error

[Bill C Riemers <briemers redhat com>]

I suppose I should mention the actual message the kernel is putting in the warning:

:Invalid RXON (0x40), channel 6

I'm not sure what RXON means...  I'm only assuming this is setting the channel number to 6, but it occurs to me that could be an invalid assumption.

There seems to be no way to open the connection in with the gnome interface to network manager.  I can only open the connection options for connections I'm actively connected to.   Is there a file on disk somewhere I can access, or an alternate UI?
