I had my router in Extender mode and now I want to switch it back to Router mode. I have it plugged into the modem, which I check with another router and is working fine with internet. The router, however, isn't connecting to internet. I've tried restarting, resetting to factory mode, and updating the firmware. Strangely, it shows an internet connection if I have it plugged into the modem while in AP or Extender mode....just not in Router. Has anyone seen this before? Is there a step I'm missing when switching back from extender to router mode?
