here is the thing i dont fool with cradlepoint routers so i am uneducated as to what works with them and what doesnt, also i thought u meant the light on the mifi was orange(that is error/download) green is good, blinking green means there is a connection present, please try your mifi on a pc directly to ck the speed and run at least 5 speedtest to get a good average, but if you were able to use the 2200 and cradlepoint together before then you can still use them now, nothing has changed that would stop that type of tether that i know of.
