I am having problems with my mifi 2200. It will not work. It shows a solid red light when it will turn on, or with a different battery it will show a solid green light but will not work or connect to vz or anything. I do not know what is wrong with the device but it does not seem to work at all. Please, does anyone have any suggestions. I have tried resetting the device and all sorts of things but nothing seems to work.
