The IP address 192.168.1.100 is a private network address frequently used by ASUS routers in repeater or access point mode, various cable modems, and IP cameras as their default management interface. When an ASUS router is switched from its default router mode to AP mode or repeater mode, it often changes its management IP from 192.168.1.1 to 192.168.1.100 to avoid conflicts with the primary router on the network. This address is also commonly the first IP in a DHCP pool, meaning it may be assigned to the first device that connects to your network.

If 192.168.1.100 does not work, try these alternatives: 192.168.1.1 (ASUS default in router mode), router.asus.com (ASUS hostname), 192.168.0.1, or 10.0.0.1. For IP cameras, the device may have been assigned a different address by DHCP — check your router's connected devices list to find it.
Here are the most commonly used default login credentials for devices accessible at 192.168.1.100:
| Username | Password | Device / Brand |
|---|---|---|
| admin | admin | ASUS Routers (AP/Repeater Mode) |
| admin | password | Various Cable Modems |
| admin | 1234 | Some IP Cameras |
| admin | (blank) | ASUS (some older models) |
| root | root | Network Cameras |
| admin | admin1234 | Various Devices |
Follow these four steps to access the admin panel at 192.168.1.100:
http://192.168.1.100 in the address bar. Press Enter. Do not type the address in a search engine — use the URL bar directly.If you cannot access 192.168.1.100, first verify that the device is powered on and connected to your network. Check your computer's IP address using ipconfig (Windows) or ifconfig (Mac/Linux) — it should be in the 192.168.1.x range. If your primary router uses a different subnet (like 192.168.0.x or 10.0.0.x), the device at 192.168.1.100 may be unreachable without connecting directly to it. Also try disabling your firewall temporarily, clearing browser cache, or using a different browser.
After accessing the 192.168.1.100 admin panel, you have control over your device's key settings and features.
Customize your wireless network by updating the SSID and password. Change your WiFi network name to make it easy to identify, especially when running the device as a repeater or secondary AP. You can also enable a guest network to provide internet access to visitors without exposing your main network.
Strengthen your network security by changing default login credentials. Change the admin password to something strong and unique. Enable MAC address filtering to whitelist approved devices, and use the admin panel to block unwanted users from your network.
Depending on your device, advanced features may include port forwarding for hosting services or games, VPN server or client configuration for encrypted connections, and Dynamic DNS setup for remote access. ASUS routers in AP mode retain most advanced wireless settings including AiMesh compatibility.
Regular maintenance ensures optimal performance. Check for firmware updates to get security patches and new features. If you experience issues, reset the device to factory defaults and reconfigure. Use the admin panel to view all connected devices and monitor bandwidth usage, signal strength, and connection quality.
Typing errors are a frequent cause of login failures. Verify your input against these common mistakes:

ASUS is one of the most popular router manufacturers worldwide, known for their feature-rich firmware (ASUSWRT) and strong performance across price ranges. Models like the RT-AX86U, RT-AX88U, RT-AC68U, and ZenWiFi mesh systems offer an operating mode switch that allows you to use the router as a wireless access point or repeater instead of a primary router. When you switch modes, the device typically changes its management IP from the default 192.168.1.1 to 192.168.1.100.
In AP mode, the ASUS device connects to your main router via Ethernet and broadcasts WiFi, extending your network coverage without creating a separate subnet. In repeater mode, it wirelessly connects to your main router's WiFi signal and rebroadcasts it to extend range. Both modes are useful for expanding WiFi coverage in larger homes or offices without investing in a mesh system.
The ASUSWRT interface at 192.168.1.100 remains fully functional in AP mode, giving you access to wireless settings, guest networks, traffic monitoring, and firmware updates. Some advanced features like the built-in firewall and QoS are disabled in AP mode since these functions are handled by the primary router.
The address 192.168.1.100 is a private IPv4 address within the range defined by RFC 1918. This standard reserves the 192.168.0.0/16 address block for use in private networks, meaning these addresses are not routable on the public internet and can only be used for communication within a local area network.
In many home and office networks, 192.168.1.100 is the starting address for the DHCP pool — the range of addresses that the router automatically assigns to connecting devices. For instance, a router with gateway IP 192.168.1.1 might assign addresses starting from 192.168.1.100 up to 192.168.1.254. This means the first device to connect would receive 192.168.1.100, the second would get 192.168.1.101, and so on.
When 192.168.1.100 is used as a static management IP (as with ASUS routers in AP mode), it is important to ensure no other device on the network has been assigned the same address. You can prevent conflicts by configuring your primary router's DHCP pool to start at 192.168.1.101 or by adding a DHCP reservation for 192.168.1.100.
| IP Address | Common Brands | Typical Use |
|---|---|---|
| 192.168.1.100 | ASUS (AP mode), IP Cameras | Secondary device / AP management |
| 10.0.0.1 | Xfinity, AT&T | ISP gateway routers |
| 192.168.0.1 | D-Link, Netgear, TP-Link | Home router default |
| 192.168.1.1 | Linksys, ASUS, Cisco | Most common router default |
| 192.168.1.254 | Thomson, BT Hub | UK ISP routers |

Pro Tip: If you are using an ASUS router in AP mode and keep forgetting the management IP 192.168.1.100, you can also access it using the ASUS Router app on your phone. The app automatically discovers ASUS devices on your network, even when they are running in AP or repeater mode, saving you the trouble of remembering the IP address.
192.168.1.100 is a private IP address commonly used by ASUS routers when operating in access point or repeater mode. It is also the first address in many DHCP pools, and some IP cameras and cable modems use it as their default management IP.
For ASUS routers, the default username and password are both admin. For IP cameras, common defaults include admin/1234 or admin/admin. Always check the label on your specific device for the correct credentials.
When you switch an ASUS router from router mode to AP mode or repeater mode, it automatically changes its management IP from 192.168.1.1 to 192.168.1.100. This prevents an IP conflict with your primary router, which likely uses 192.168.1.1 as its gateway address.
Yes, you can change the management IP address through the admin panel under LAN settings. This is useful if 192.168.1.100 conflicts with another device on your network. Choose an address within your subnet that is outside the DHCP range to avoid future conflicts.
Open Command Prompt (Windows) or Terminal (Mac/Linux) and type ping 192.168.1.100. If you get a reply, the device is active. You can also check your primary router's connected devices list or use a network scanner app like Fing to discover all devices on your network.
It depends on the context. For ASUS routers in AP mode, 192.168.1.100 is a statically assigned management IP set by the firmware. However, on other networks, this address might be dynamically assigned via DHCP to any device that connects. You can set up a DHCP reservation to ensure a specific device always gets this address.
An IP conflict will prevent one or both devices from being accessible. Change one device's IP address to resolve the conflict. For ASUS APs, the firmware automatically switches to 192.168.1.100 to avoid conflicts with a primary router at 192.168.1.1, but if your primary router also uses .100, you will need to change the AP's address manually.
