Here's one for everyone, every now and again, general web browsing (facebook, etc), stops working. Browser just sits there trying to connect to the site. Now here's where it gets interesting. I set my browser up to use a proxy (in this case, a private one back at home, not on port 80), and voila! Browsing works again, turn this off, and browsing is again broke. Restarting the MiFi works for a coupla minutes, then returns to this. I know I'm nowhere near my data cap, and everything else (IRC, Skype, etc) work just fine.
