Re: Netgear MA401 wireless cards

Warner,

There is some strange type of interaction between debug mode in the wi0
driver and changing channels.

It seems that if I have debug turned on the driver won't pick up data
on the new channel. The second I turn debug off the data starts flowing
again.

If debug is off the channel change works immediately.

chip# ifconfig wi0 -debug
	*** data flows
chip# ifconfig wi0 channel 8
	*** data flows
chip# ifconfig wi0 debug
	*** data flows if you are lucky
chip# ifconfig wi0 channel 9
	*** data stops until the -debug command
chip# ifconfig wi0 -debug
	*** data flows again after slight pause

Hhmm...
