Ok, you have installed the Broadcom STA driver for the device I see. Didn't the wifi work without that driver? A 43224 card should work out-of-the-box, with a different driver (brcmsmac aka brcm80211), and that driver uses wlan0 instead of eth0/1. You could try uninstalling the driver (bcmwl-kernel-source in Synaptic). In case wifi stops working completely without STA driver, please run sudo rm /etc/modprobe.d/blacklist-bcm43.conf to restore it.
