Selecting the correct wireless network essid

[garland3]

Hi,
I have an overo gumstick that is running the angstrom disto.
I'm using a usb wifi dongle to let it connect to my home network.
I've used these commands to get it to work.

wpa_passphrase 1234567890 waylongkeythelongerthebetterbecausewecareaboutsecurityalot >> wpa_supplicant.conf

# This works with my current home rounter. 
auto wlan0
iface wlan0 inet dhcp
	pre-up iwconfig wlan0 essid "1234567890"
	pre-up ifup wlan0
	pre-up wpa_supplicant  -iwlan0 -c/etc/wpa_supplicant.conf &
	down killall wpa_supplicant

I have my overo gumstick powered from my car sometimes and I want to connect to the internet using my phones 3G to wifi tethering capability.

How do I set up the wireless interfaces and wpa_supplicant so that it automatically determines which wifi network is within range and connects to it?

Thanks for the help,

Anthony G.

Hi There,

You ought to be able to load up several different network definitions in your wpa_supplicant.conf file and it will use whichever one it can see, or the one you give highest priority if it can see several networks it recognises.

Check this wpa_supplicant man page for some examples.

Let us know how you get on.
