Update as I type on the DIA free lowfi: I had to blow out my OpenDNS settings and allow the hotspot to assign DNS settings automatically - something I just thought up, because this lowfi network provides no phone numbers and no tech support of any kind.

Luckily, I'm now poking along at however many kpbs this kleenex-and-spit network provides.

Has anyone stumbled across a phone number to call regarding login issues?

In doing a Google search, it does appear that the airport is crowing about the "amazing lack of complaints." Of course, if you provide no method to communicate complaints, then I guess everything's peachy, eh?
