Help with RAX78 in bridge mode

Hi,

I just recently purchased AX8 Nighthawk router and I am having some issues configuring router in bridge mode.  Here's a little background on my current setup.  I live in a rural part of town and the only internet access that I currently have is through a mobile hotspot.  I had an older router that I had used in bridge mode to broadcast my signal throughout my house, but that router no longer works for me.  With the AX8, I was able to set it up in bridge mode and connect it to my hotspot, but for some reason, the AX8 is using the same network SSID as my hotspot.  All of the options available in the configuration to change network settings are all grayed out and not accessible.  I am currently connected to the AX8 router via Ethernet to rule out any wireless issues, but as of now, I cannot perform any kind of administration with my AX8 router.  My mobile hotspot only supports a limited number of connections and I noticed that when I connect to the WIFI network, it takes up a connection on the hotspot and it is listed in the AX8 configuration screen under 'Attached Devices'.  Does anyone know what I am doing wrong, or if I am taking the wrong approach in setting up my wireless network?

Thanks,

James
