Thanks - I'll try that script. That appears to be the same script as what is suggested on Maemo except it is using version 2. Perhaps that will make the difference. I'll report back my findings.

When I tried the original DummyIAP script (version 1) it make a DEFAULT entry that I could connect to in the connections wizard, but it would break my real wireless connection in the process.

Perhaps the real solution is to connect to the dummyIAP first and then connect automatically to my real wireless connection. I'll have to research how to connect to the DEFAULT network via a script so I could add that to my existing autoconnect script. The only stumbling block that might occur is that I am connecting during the boot process (so the tablet is already connected by the time the desktop appears). I'm not sure if the stock IC is far enough along at that point to allow someone to connect to the DEFAULT network.
