How To Clear Wireless Preferred Network For Mac Os X Update

I am doing the switch frequently, but i have the following pb, and didn't find anything on google that might help:
when i switch networks , or even ips on the same network, Mail.app loses connectivity with the server (i use imap) , and also the gmail notifier (which uses imap too) loses connectivity, and there is no way to regain it except switching back to the old ip. i suppose there is some kind of imap connection caching feature that's under the hood in os x but i couldn't find anything about that on google. any ideas ?

I am sorry if this is a stupid question, but what is wrong with using the AirPort menu to select which wireless network you want to use? Is the point simply to have a keyboard shortcut to switch between wireless networks?

Or you could just go into the Network preference pane and for each location profile, go under Advanced->Airport and either remove or lower the priority of the access point you don't want from the list of Preferred Networks.

Maybe you already tried, but I wonder if ifconfig en1 down; ifconfig en1 up might be enough to reset the airport card.

/usr/sbin/scselect 'new location name'

Then again, I do not have Snow Leopard, so I don't know if the scseclect command still exists.

You can now -setairportnetwork directly, and not have to mess with locations.

I just verified with ifconfig that immediately after using networksetup to set the network, the DHCP information was renewed per the new network.

/usr/sbin/networksetup -setairportnetwork AirPort (SSID) (PASSWORD)

So, it shouldn't be too much trouble to make an applescript that toggles between two or more networks in that fashion.

Not sure if the IMAP or Google mail issues would be solved by this or not.
