ETC as running ftp or ssh instead of webserver

There is another problem with the instructions in this thread, is it possible that the wifi adapter now shipping with the ETC requires a different driver?

The line “wpa_supplicant -B -D nl80211,wext -i wlan0 -c <(wpa_passphrase “NETWORK_NAME” “PASSWORD”)”

returns

“nl80211: Could not configure driver mode”

on my ETC. Prodding the system tells me that I have the rt2870 chip in the USB wifi dongle that came with my ETC. What driver should I use instead?
