Nighthawk MR60 - Satellite stuck in Wired mode

Model version: Nighthawk MR60

Firmware version: v1.1.7.134_2.0.65 (all devices have the same firmware)

I recently upgraded my home to a fiber connection, and noticed all my devices were capped at 100mbps. This was due to some older Cat5 connections in my home being hooked up to the router and both satellites. I have since removed the Cat5 connections and all devices in the home are now getting the correct speeds (upwards of 500mbps).

However, one of the satellites, despite multiple factory resets, syncs, and other troubleshooting attempts seems to be stuck in wired mode, despite no wired connection existing to it anymore. The other satellite is set to wireless mode and is functioning fine. I could not find any other documentation or troubleshooting threads in my searches to fix this.

Any help would be appreciated!
