Virgin Mobile Mifi 2200

Anybody else having a hell of a time getting this thing to work with a Mac? I have a pretty new MacBook Air and am having a hell of a time getting it to play nice with my Virgin Mobile Mifi 2200. The Mac times out when connecting, it won't ever get beyond entering the wifi access password. I was able to connect to the Mifi with my phone, and laboriously reconfigure the wifi to not require a password. No luck. Tried again, turned the wifi from 802.11B/G to B only, then it would connect, but I'd have no active connectivity. So I manually set it to channel 2 and then channel 10, no difference there. Manually changed the DNS to Google's Public DNS servers, and then I could resolve DNS. So....what does that mean? It's really a routing/config issue?

After an hour of messing with it, I gave up. Not worth the hassle. I'll use my wife's USB modem instead (if that'll work) and never top-up the Mifi again.
