192.168.123.1 Admin Login

192.168.123.1 is a Class C private IPv4 address used as the default gateway by a select group of router manufacturers. The brands most commonly associated with this IP include Zyxel (notably the Armor G5 NBG7815), AMIT, PROLiNK, and LevelOne. If your router came preconfigured with this address, typing http://192.168.123.1 into your browser will take you directly to the admin login panel. Unlike the more widespread 192.168.1.1 or 192.168.0.1, this address sits in the less commonly used 192.168.123.x subnet, making it a more distinctive default gateway choice. Because it is a private IP address, it is only reachable from within your local network — it is never exposed directly to the public internet.

How to Access 192.168.123.1

To access your router's admin panel at 192.168.123.1, follow these steps:

1. Make sure your device (PC, laptop, or smartphone) is connected to the router — either via an Ethernet cable or over Wi-Fi.
2. Open any web browser (Chrome, Firefox, Edge, Safari) and type http://192.168.123.1 into the address bar. Do not use a search engine — type it directly into the address bar.
3. You will be presented with a login page. Enter your router's default username and password. For most devices using 192.168.123.1, the default credentials are admin / admin or admin / password. For Zyxel Armor G5 (NBG7815), you can also try accessing it via http://zyxelwifi.com or http://zyxelwifi.net.
4. Once logged in, you can manage your Wi-Fi settings, change passwords, configure port forwarding, update firmware, and more.

Because 192.168.123.1 is a private IPv4 address, any device on your local network could technically be assigned this address. To avoid an IP address conflict, ensure only your router uses 192.168.123.1 as its LAN IP. Other devices on the same network will be assigned addresses like 192.168.123.2, 192.168.123.3, and so on by the router's DHCP server.

Router Brands That Use 192.168.123.1

Not all router manufacturers use 192.168.123.1 — it is a less common default gateway compared to 192.168.1.1 or 192.168.0.1. Below are the brands and models confirmed to use 192.168.123.1 as their default gateway:

• Zyxel — The Zyxel Armor G5 (model NBG7815), an AX6000 Multi-Gigabit Security Wi-Fi 6 Router, uses 192.168.123.1 as its default LAN IP address in Standard Mode. Zyxel is a well-established Taiwanese networking brand known for enterprise and home routers, switches, and modems.
• PROLiNK — Several PROLiNK router models, including the PRT7007L and the WNR1008, use 192.168.123.1 as their default gateway. PROLiNK is a networking brand popular in Southeast Asia, offering ADSL modems, wireless routers, and broadband equipment.
• AMIT — AMIT is a Taiwanese manufacturer of industrial-grade wireless routers and M2M gateways. Some AMIT models use the 192.168.123.x subnet, with 192.168.123.1 as the default gateway.
• LevelOne — LevelOne (a brand by Digital Data Communications) produces networking equipment including routers and access points, some of which default to the 192.168.123.x subnet.

If your router is from one of these brands and you cannot reach the admin panel at 192.168.123.1, it is possible that the default IP has been changed. See the troubleshooting section below for guidance.

If You Can't Access 192.168.123.1

If typing http://192.168.123.1 into your browser does not load the router login page, work through the following checks:

• Verify your gateway address: Open a Command Prompt (Windows: press Win + R, type cmd, press Enter) and run ipconfig /all. Look for the Default Gateway field. On macOS or Linux, open Terminal and run netstat -nr | grep default. If the gateway shown is not 192.168.123.1, then your router may be using a different IP — check our guide to find your router IP address.
• Check your connection: Make sure you are connected to the correct network. If you are on a guest Wi-Fi network or a different SSID, you may not be able to reach 192.168.123.1.
• Try HTTPS: Some routers, especially the Zyxel Armor G5, require https://192.168.123.1 (with the S) rather than the plain HTTP version. Try both.
• Disable VPN or proxy: If you have a VPN or proxy active on your device, it may block access to local IP addresses. Disable it temporarily and try again.
• Clear browser cache: Old cached data can sometimes interfere. Try opening an incognito/private window and navigating to http://192.168.123.1.
• Try a different browser or device: If one browser fails, try another. You can also try from a different device connected to the same network.
• Reboot your router: Power cycle your router by unplugging it for 30 seconds, then plugging it back in. Wait for it to fully restart before trying again.

Factory Reset Instructions for Routers Using 192.168.123.1

If you have forgotten your admin password or cannot access the panel at 192.168.123.1, a factory reset will restore all settings — including the default IP address — back to their original values. Warning: A factory reset will erase all your custom configurations, including Wi-Fi name, password, and any port forwarding rules.

Zyxel Armor G5 (NBG7815)

1. Ensure the router is powered on.
2. Locate the RESET button on the back of the device.
3. Use a pin or paperclip to press and hold the RESET button for more than 5 seconds until the LED indicator changes.
4. Release the button and wait for the router to reboot fully (this may take 1–2 minutes).
5. Once restarted, the default gateway will be restored to 192.168.123.1 and you can log in with the default credentials printed on the device label.

PROLiNK Routers (e.g., PRT7007L)

1. Make sure the router is powered on.
2. Find the RESET pinhole button, usually located on the back or bottom of the device.
3. Insert a pin or paperclip and press and hold for approximately 15 seconds.
4. Release when the LEDs flash or the device restarts.
5. After reboot, navigate to http://192.168.123.1 and log in with admin / admin.

2. Press and hold for 10–15 seconds using a pin or paperclip.
3. Wait for the device to reboot completely.
4. Access the admin panel at 192.168.123.1 using the default credentials from your device's label or manual.

Changing Your Router's Password at 192.168.123.1

Keeping the default admin password on your router is a serious security risk. Anyone connected to your network could log in to 192.168.123.1 and change your settings. Here's how to update it:

1. Log in to your router's admin panel at http://192.168.123.1 using your current credentials.
2. Navigate to the Administration, System, or Management section — the exact label depends on your router brand. On Zyxel routers, look under Maintenance > User Account. On PROLiNK routers, look under Administration > Password.
3. Enter your current password, then type your new password twice to confirm.
4. Click Save or Apply. Your router may prompt you to log in again with the new password.

Choose a strong password that is at least 12 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid using easily guessable information like your address or birthday.

It is also a good idea to change your Wi-Fi network name (SSID) and Wi-Fi password from the defaults while you are in the admin panel at 192.168.123.1. Default SSIDs often reveal your router's brand and model, making it easier for attackers to target known vulnerabilities.

What Is 192.168.123.1 as a Private IP Address?

192.168.123.1 is a Class C private IPv4 address, falling within the reserved private IP range of 192.168.0.0 – 192.168.255.255 as defined by RFC 1918. This means it is not routable on the public internet — it exists solely within your local area network (LAN). Your Internet Service Provider (ISP) and the wider internet will never see 192.168.123.1 directly; instead, your router uses Network Address Translation (NAT) to map all your local devices to a single public IP address when communicating with the outside world.

When your router uses 192.168.123.1 as its gateway, it typically assigns addresses to connected devices within the 192.168.123.x subnet. For example:

• Your laptop might receive 192.168.123.2
• Your smartphone might receive 192.168.123.3
• Your smart TV might receive 192.168.123.4

These addresses are dynamically assigned by the router's built-in DHCP server. Every device that connects to your network — whether via Wi-Fi or Ethernet — gets a unique private IP in this range, allowing the router to correctly route data packets to and from each device.

The 192.168.123.x subnet is less commonly used than subnets like 192.168.1.x or 192.168.0.x, which means routers using 192.168.123.1 are less likely to experience IP conflicts when connected to other networks (for example, when using a VPN or connecting two routers together).

Related IP Addresses in the 192.168.123.x Subnet

The 192.168.123.0/24 subnet contains 254 usable host addresses (192.168.123.1 through 192.168.123.254). While 192.168.123.1 is the most commonly used gateway address in this subnet, a few other addresses in this range are also notable:

• 192.168.123.254 — Used as the default gateway by some older Zyxel, AMIT, LevelOne, Sitecom, and Alcatel devices. It is the second most common gateway address in this subnet.
• 192.168.123.100 — Sometimes used as a static IP for network-attached storage (NAS) devices or printers on networks where 192.168.123.1 is the gateway.
• 192.168.123.2 – 192.168.123.253 — These addresses are available for assignment to client devices (computers, phones, tablets, smart home devices) by the DHCP server at 192.168.123.1.
