Find Your Asus RT-AC66R Router IP Address
We need to find your Asus RT-AC66R router's internal IP address before we can log in to it.
| Known RT-AC66R IP Addresses |
|---|
| 192.168.1.1 |
Choose an IP address from the list above and then follow the rest of this guide.
If later on in this guide you do not find your router using the IP address that you pick, then you can try different IP addresses until you get logged in. I will not hurt anything to try different IP addresses.
If, after trying all of the above IP addresses, you still cannot find your router, then you have the following options:
- Check our out Find Your Router's Internal IP Address guide.
