I just got Railwire Fiber Optic Service and as always I login to LCO provided ONU wifi router and then I deleted the route mode created by my LCO and setup the Bridge mode and connected it to my Dual Band Netgear Router, Everything was working as expected but when I reboot the LCO provided ONU wifi router it's revert back to the route mode which is my LCO created setup in beginning so I called him and he said it's auto managed from his side so he can remotely help me if any config problem arrive there in router and if I still want then he can set up the bridge mode. Is your LCO's working the same way as mine?
