750S Static IP for WIFI

I’m trying to setup the WIFI to use a static ip instead of dhcp. The problem I’m having is that the network (which I don’t control) is giving me an address that is already in use by another device. I went into advanced settings and edited the WWAN interface to make it static, but after a short period (15 minutes or so) it reverts back to the DHCP assigned address.

I also tried the clone mac address but it doesn’t look to work for the wireless interface. Perhaps its only for the ETH wan interface.

I’m running latest 3.007


First disable repeater manger:

SSH to the router and rename /usr/bin/gl_health

Then do it again in luci.
