I have slackware64 13.37 installed on my laptop, with wicd 1.7.0 as network manager.
By default wicd connects using the internal wifi card.
I have a much better usb wifi card that I would prefer wicd to use.
How can I set wicd to first try to connect using the usb wifi card, but if it is not available, to switch to the internal wifi card?

The internal card is

04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

The usb card is

Bus 002 Device 003: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter

Unfortunately, Wicd only allows a single wired and a single wireless interface at a time. Slackware-current now comes with NetworkManager, however, so if you want to run the latest development version you can use it instead of wicd (warning: I don't use NetworkManager so I can't say that it will do what you want, but it it more feature rich than wicd, so it may well).
