How to find ip address of the Asus RT-AC86U in Access Point mode

guiip addresswireless-access-point

I'm using an Asus wireless router model RT-AC68U and can connect fine to the internet using it wirelessly. I configured the router to be an Access Point, but having done so, I can no longer locate the GUI to adjust the router as I have no idea what its IP Address is anymore. The router is plugged into a cable modem and router which is a model SMCD3G is a business class gateway labeled Comcast Business IP Gateway. This gateway is assigning ip addresses in the range 10.1.10.XX and I went to the web interface at and listed the connected devices and see my laptop which is connected to the Asus access point along with a few other devices, but none of the devices listed are the Asus router (I tried all the six ip addresses listed).

How can I determine the IP Address of my Asus router in access point mode so I can see the GUI interface again to control the router other than by doing a factory reset?

I know I'm resurecting an old, dead thread, but can't resist.

  1. Connect to your AP.

  2. Open a Command Prompt.

  3. Type in: arp -a

The output will look like this:

Interface: --- 0xa
Internet Address      Physical Address      Type          10-77-b1-02-e9-59     dynamic           68-7f-74-be-72-15     dynamic         bc-ae-c5-ec-04-96     dynamic         ff-ff-ff-ff-ff-ff     static            01-00-5e-00-00-16     static           01-00-5e-00-00-fb     static           01-00-5e-00-00-fc     static       01-00-5e-7f-ff-fa     static       ff-ff-ff-ff-ff-ff     static

You may have multiple Interfaces listed, refer to the one that matches the computer's IP address.

In this example, my computer is

I would want to try and connect to all other 192.168.x.x.

Since I know is my router, I tried .107 and .255, and voila! .107 is the access point.

EDIT: Just an FYI but .255 can't be the access point anyway, since it's the broadcast address for that subnet. So by elimination, .107 is the access point.
