My univeristy has a lot of wifi ap and therefore I have a very long list of wifi ap in my wicd-client. I try to use "use-setting-global" to make sure I can connect any of them without setting the password and identity each time I change my location. However it doesn't work. Every time I want to connect wifi ap, I have to reconfigure this ap.
Is it possible to configure wicd to assemble all the APs with the same ESSID together?
Or is it possible I configure it wrong?

What's more, can we use the system CA, just like that in Network-manager? Every time I configure the AP, I have to input the location of my system CA, which is quite a long input.

Thanks!
