problem with multiple AP's with same ssid(WiFi question)
 

If you're in an environment where you have multiple APs (wireless access points)with the same SSID;
Is it possible for you to specify which one you wish to connect to based on its Bssid (or mac)?

I remember that iwconfig allows you to specify a mac for an ap. Check man page of iwconfig.

isn't iwconfig just for checking your connection?

`iwconfig` can most certainly be used to associate with one access point / network over another. As Sarin said, check the manpage.

When I log onto my home network, I have the following as part of a handy script:

iwconfig eth1 essid 'My Network' AP '00:00:FF:DD:43:78' channel 7 key s:'Mykey'

Remember, most of the time, GUI applications are a frontend for all the work that's going on in the background. Wicd or other network managers may use commands like the above to allow you to associate to a given network.
