If it says took to long to respound means it is still starting up so give it 5min I would say. It if is connected to a WAN it should setup pretty quickly and you get a solid White light. If it is not connected will flash blue and tack a little bit because of no dhcp.
Try a private browser window and a wired connection. Note: If your browser always redirects to LuCI (http://192.168.8.1/cgi-bin/luci), you can visit: http://192.168.8.1/index instead of http://192.168.8.1.
If that does not work try CMD command in windows, then ipconfig and get the default gateway (should be 192.168.8.1 maybe different)
DNS cache might need to be cleared so in CMD line enter ipconfig /flushdns
