hot spot will not connect to surface rt

[FRCWW]

I have a GSIII, about ten days ago I was operating on a 4G motherboard. I switched to a 4G LTE motherboard with a 4.3 OS for an increase in speed. When I was operating on 4G I had no problems going online with my hotspot. On 4G LTE the phone will not hookup. What can I do to get the GSIII 4G LTE to hook up??????
