I have 4 permanently mounted modems and all was fine untill about 6 days ago. All modems connected GREEN and the speed was okay. 6 days ago, all of a sudden 3 of the MIFI 2200's connect in BLUE and refuse to connect any other way no matter what sequence the modems are powered up. I have attempted to disable the roam feature via the VZ Manager but no change. All updates are current. Any ideas on how to resolve this problem? Normally I would not be concerned but the speed is the same if I disconnect the 3 roamers.
