Autofill not working?

I've found autofill to be a little weird also.

After you log in once, it's supposed to remember it next time, and auto connect without the need to go through safari.

I.E. at work, now I've had it log in to the web access page once, it logs into the wireless network automatically much like it would any normal WiFi router.

However, there are a number of WiFi zones running on essentially the same network here, and the Touch will only connect to one of them through autofill. I think the other zones just confuse it, since it recognizes the network, but not the access point.

Either way, usually it learns after a bit of faffing around. If I happen to stumble over the exact sequence of steps to make it happy, I'll post back.
