If you know in advance the network you will be associating with (like you switch between Home, Work, Panera, Starbucks, etc...), you can setup System Preferences -> Network -> Locations, then use the scselect command. For example:
scselect "Home Location Name"
scselect "Work Location Name"
scselect "Panera Location Name"
Each location can has its own preferred networks, as well as proxy settings, fixed vs DHCP IP address assignment, DNS servers, etc...
I would experiment with the Airport command, but I'm in a Panara on a 10.5.8 Leopard system at the moment. My 10.6.2 Snow Leopard system is at work
good point. I tried that before. However, it does not really seem to work for me...So let me explain, hope you understand my probleme: If I create more than location for example
and I change the networkname for Airport for the Test location to "wlan1" it will change all the networkname also in the Automatic and Home location to "wlan1"...that is not want I really want....
Any other choice...?
Thanks & cheers
So in Snow Leopard it won't come up as it does in Leopard as such:
doug-penningtons-power-mac-g4:~ dougp$ sudo airport -A --associate
Network Name (SSID):
No. It does not. It generates a long Usage message when you try to use -A and or -A --associate.
sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -A --associate
airport: invalid option -- A
airport: unrecognized option `--associate'
Usage: airport <interface> <verb> <options>
If an interface is not specified, airport will use the first AirPort interface on the system.
<verb is one of the following:
prefs If specified with no key value pairs, displays a subset of AirPort preferences for
the specified interface.
Preferences may be configured using key=value syntax. Keys and possible values are specified below.
Boolean settings may be configured using 'YES' and 'NO'.
logger Monitor the driver's logging facility.
sniff If a channel number is specified, airportd will attempt to configure the interface
to use that channel before it begins sniffing 802.11 frames. Captures files are saved to /tmp.
Requires super user privileges.
debug Enable debug logging. A debug log setting may be enabled by prefixing it with a '+', and disabled
by prefixing it with a '-'.
AirPort Userland Debug Flags
AllUserland - Enable/Disable all userland debug flags
AirPort Driver Common Flags
AllDriver - Enable/Disable all driver debug flags
AirPort Driver Vendor Flags
AllVendor - Enable/Disable all vendor debug flags
AirPort Global Flags
LogFile - Save all AirPort logs to /var/log/airport.log
<options> is one of the following:
No options currently defined.
Configuring preferences (requires admin privileges)
sudo airport en1 prefs JoinMode=Preferred RememberRecentNetworks=NO RequireAdmin=YES
Sniffing on channel 1:
airport en1 sniff 1
-c[<arg>] --channel=[<arg>] Set arbitrary channel on the card
-z --disassociate Disassociate from any network
-I --getinfo Print current wireless status, e.g. signal info, BSSID, port type etc.
-s[<arg>] --scan=[<arg>] Perform a wireless broadcast scan.
Will perform a directed scan if the optional <arg> is provided
-x --xml Print info as XML
-P --psk Create PSK from specified pass phrase and SSID.
The following additional arguments must be specified with this command:
--password=<arg> Specify a WPA password
--ssid=<arg> Specify SSID when creating a PSK
-h --help Show this help
Doug, sorry, but as stated above Bob´s original answer is not a solution at least not that I see it. Maybe I am doing something wrong here.
Strange that it is not possible to tie a certain SSID as default to a specific location network profile.
Strange that in Snow Leopard the airport help lists legacy arguments for the airport command but just neglects the argument "associate" that existed in previous releases. Just a strange way to support compatbility...that´s frustrating.
Anybody else with a solution that might help?
Appreciate it. Thanks
