1 ER7206 (previous asus router with same issue)

I have been running into an issue where when my WAN goes down for whatever reason, I lose access to my local network over WLAN.  I can connect to Wifi but DHCP doesn't seem to be working and I can't connect to any other device (like the controller).  I had this issue when I was using my Asus router as a WAN device and recently with a ER7206.  Is there some setting I have set somewhere that causes this?
