Mifi works fine as a wifi unit on XP netbook, but when connecting to Vista laptop, Mifi ONLY works as wifi; not as WWAN. ie, when the cable is installed between the Mifi and laptop, I get an error 711 when trying to use the wizard to make it a WWAN device. I spent a LOT of time with tech support, reinstalling VZAccessManager. We tried with the 6x version and also the newest, 7x. No joy.
Mifi works great with our iPod Touchs!
