The problem is that Boingo is a paid subscription-based wifi internet provider which uses a proprietary software client that you have to download and install in your laptop in order to login to the network.
You might want to double check that. I've used Boingo occasionally on my linux laptops with nothing more than wicd and a browser (usually Firefox). Basically, wicd saw and connected to the Boingo network and when I fired up Firefox, I was redirected to a page that asked for username and password. After supplying those, I was on the network. It absolutely blew chunks, but I was on the network (Boingo in O'Hare is a waste of dough).
I wouldn't be surprised if they had some proprietary Windows abuseware, but last time I used it (admittedly a few months ago) there wasn't a requirement that you use it. Given how wireless networks operate, there shouldn't be a need for proprietary software. It just gets in the way.
