Can wlan0 & wlan1 both be active at the same time or will they interfere with each other?

I recently installed Lubuntu on an HP Pavilion which had previously been running Windows XP. The internal Broadcom wireless card was experiencing some drop off issues & is under Lubuntu as well. Stuck a new Ralink external wireless adapter into the the USB port & now the wireless is working very well.

Uninstalled the b43 firmware so the BCM4306 card won't work but it still shows up under the wireless device list as wlan0 along with the Ralink adapter which is wlan1. Not very good with linux so not sure if there's a "device manager" or the like to disable the Broadcom card. Will it hurt to leave both wlan0 & wlan1 active even tho wlan0 will never be used?

Or can someone help me disable the internal Broadcom card? Found this command = "sudo ifconfig wlan0 down" but I'm not really sure what I'm doing here. Does this command only bring wlan0 down for the current session & will wlan0 then reappear after the next restart?

thanks

You can have both interfaces up, that doesn't mean that they're active. Actually they're active when they have an ip address, wich in your case, it doesn't seem to be happening.

If you really don't want to have both interfaces up, you can take one down with the command you gave:

sudo ifconfig wlan0 down

If you want it up again, just do

sudo ifconfig wlan0 up

I would suggest you don't mind with both cards being up, as you are currently using the wlan1.
