Subject:	[OS2Wireless] XWLAN script for changing between wifi and wired LANs

After quite a bit of testing I have developed a xwlan script that changes between a 'Home' profile wifi lan0 and a wired lan1. The change is initiated by being attached to the wifi lan using the 'Home' profile and turning the wifi radio off in xwlan. To change back, the wifi radio is merely turned on. THe script also allows for changing between the 'Home' wifi profile with fixed IP addressing and a 'Travel' wifi profile with DHCP addressing. I also use the 'Travel' section to handle hotspot connections without a profile name. This latter option has not been tested. See the attached zip file. You will probably need to change the TCP/IP setup and profile names to what you use. A few things I have noticed: 1) When the radio is turned off the SSID does not appear to be passed to the script (I get a NULL string). So I used the profile name as a test instead of the SSID as indicted in the sample script. 2) I had to disable the TCP/IP setup in the 'Home' profile and do the setup in the script because I got a popup error message about using duplicate fixed IP addresses for both lan0 and lan1. The 'Travel' DHCP setup was ok, no configuration statements are needed in the script except for ensuring that the wired LAN is deleted. 3) The wifi is sometimes stubborn about connecting to a profile, even if the AP is only a few feet away. I'm not sure if this is a xwlan script problem or related to interference from local networks. In this case, the network is usually left in the fixed ip wired LAN1 configuration. I found that if I suspended the laptop, the profile usually connects upon resume. 4) Sometimes the 'Home' profile connects but the connect event is not sent to the script. In this case, the infamous 'IP disabled' logo is shown. I correct this by manually issuing the appropriate wifi script commands. Attached File: xwlan.zip (2322 bytes)
