i have run wheezy installer
it can config my usb wifi adapter
that is, it connect to access point
but it can't download files
the access point is hot spot of cell phone, it uses wpa2
the usb adapter works in stretch with lines below :
(from interfaces file)
allow-hotplug wlx0011d8bff26f
iface wlx0011d8bff26f inet dhcp
wpa-ssid fake
wpa-psk 1234abcd1234
i think wheezy use same lines as above except device name is wlan0
