Router orange light no internet connection
My Archer ax23v router can't get internet signal from modem (orange light). I have two of these - both can connect with no problems to NTT modem at office. But both cannot connect to NTT modem at home. Office NTT modem is model GE-ONU PR-400MI. Home modem is smaller GE-ONU model. Both modems are brand new, both routers are brand new. Tried different cables, tried resetting, tried unplugging and restarting. Home older modem / router setup works fine. Is it possible that this model does not work properly with this specific modem model? Any suggestions?
