4510L MIFI setting to LTE only

[deloswilbur]

Has anyone had any luck with this?  I am speaking of setting it to LTE only and having it actually connect to LTE.  I looked through previous messages and have done searches for this and new firmware but not finding anything new.  I have been alternating back and forth between this setting and Global.  Example being I set it to LTE only last night and it stayed connected for several hours, but I konw when I go home today it will be either hung, or happily connected to EVDO with the LTE only setting still in there.
