192.168.100.1 Login Admin: Change your Router Password and Router settings.

192.168.100.1 Login Admin.

192.168.100.1 is an important default gateway IP address in many Pakistan, Philippines, Mexican and Chinese home broadband setups, but it is also one of the most misunderstood.

Unlike 192.168.1.1, which is mainly used for Wi-Fi routers, 192.168.100.1 in for example China, is more often used for the admin page of a fiber modem (ONT) or a carrier-provided gateway device. It is especially common on fiber equipment provided by China Telecom, China Unicom, and China Mobile.

In real life, many users try to log in to their router and get redirected to 192.168.100.1, or they find that 192.168.1.1 does not open, but 192.168.100.1 does. This guide explains how Chinese home networks are structured, what 192.168.100.1 is used for, which devices commonly use it, how to log in, default usernames and passwords, why the page might not open, and includes a full 30-question FAQ to help you fully understand this address.

What Is 192.168.100.1?

192.168.100.1 is a private IPv4 address in a local network range. You cannot open it from the public internet. In home networks, it is most commonly set as the default management address of the fiber modem (ONT), not the Wi-Fi router.

When your home uses fiber internet, the ISP usually installs a fiber modem (ONT) to convert the fiber signal into Ethernet. The ONT itself has an admin page, and on many common models, the default admin IP is 192.168.100.1.

192.168.100.1 Login Admin – Quick Guide

1. Make sure your phone or computer is connected to the ONT network or the router network under it.
2. It is recommended to use a computer, or on a phone, turn off mobile data (4G/5G).
3. Open a browser and enter http://192.168.100.1 in the address bar.
4. Enter the ONT admin username and password.

If the page opens normally, it means the ONT management address in your current network is 192.168.100.1.

192.168.100.1 Login Admin – Step-By-Step Guide.

Many internet devices have a built-in settings page (an “admin page”). You open that page by typing an IP address into your browser. One common IP address is 192.168.100.1.

People usually search for 192.168.100.1 when they want to:

• Log in to their modem or router settings
• Change Wi-Fi name (SSID) or Wi-Fi password
• Fix internet problems
• Check connected devices
• Change network settings (advanced users)

Important: 192.168.100.1 is often used by fiber modems (ONT) or cable modems. Many normal home Wi-Fi routers use 192.168.1.1 or 192.168.0.1 instead.

1. What Is 192.168.100.1 and What Is It Used For?

192.168.100.1 is a private IP address used inside your home network. It is not a public website, and it will not open unless you are connected to the correct device.

Some devices (modems, fiber ONTs, gateways, and a few routers) use this address as their default login page. The login page is where you can manage settings like:

• Wi-Fi settings (name and password)
• LAN and WAN network settings
• DNS settings
• DHCP settings
• Security options
• PPPoE settings (common with many ISPs)
• WLAN and WPS options
• MAC filtering and access control

Most devices use port 80 (the normal web port). That is why people usually just type 192.168.100.1 and do not type a port number. If the device uses a different port, you must include it (example: 192.168.100.1:8080).

2. 192.168.100.1 vs 192.168.l00.1 (Common Typos and Login Mistakes)

This is one of the biggest reasons people cannot open the login page.

192.168.100.1 uses the number 1 and the number 0.

But many people accidentally type letters that look similar:

• l (lowercase L) instead of 1
• O (capital o) instead of 0

So they type something like 192.168.l00.1 (with an L) and the page will not load.

Common wrong versions that will NOT work

• 192.168.l00.1
• 192.168.l0.1
• 192 l.168.1.1
• 192 l.168.0.1
• 192 l.168.10.1
• 192.168.100
• 198.168.l00.1
• 168.192.l00.1
• 192.168100.1
• 192.168.100.l
• 192.168.1001
• 192.168.1.100.1
• 192.168|100.1
• 192.168 100.1

Another common mistake is typing the IP into a search box instead of the browser’s address bar. Always click the address bar at the top of the browser before typing.

Simple rule: Type the address exactly like this: 192.168.100.1

3. How Do I Log In to 192.168.100.1 to Access My Settings?

Follow these steps. They work for most modems, fiber ONTs, and routers that use 192.168.100.1.

Step 1: Confirm the correct login address

Check your device label or manual. Many devices print the login IP, username, and password on the back or bottom.

Step 2: Connect to the correct network

• If you are using Wi-Fi, connect to the modem/router Wi-Fi network.
• If you are using a cable, connect your computer to a LAN port on the device.

Step 3: Open your browser

Use Chrome, Edge, Safari, or Firefox. Then click the address bar at the top.

Step 4: Type the IP address

Type 192.168.100.1 and press Enter.

Step 5: Enter username and password

On the login screen, enter the username and password from your device label. Many devices use:

• admin / admin
• admin / password

But it depends on the device brand and ISP. Always trust the label first.

4. How Do I Reset My Router Username and Password?

If you changed the login password and forgot it, resetting the device is often the only option. This resets everything back to factory settings.

How to reset (most devices):

1. Keep the device powered on.
2. Find the small reset hole (often labeled Reset).
3. Use a pin or paperclip and press the reset button for 10–15 seconds.
4. Release the button and wait for the device to reboot.

After reset, you can log in again using the default username/password shown on the device label.

Warning: Resetting can remove ISP settings. On many fiber modems, resetting may break your internet until the ISP reconfigures it. If your modem belongs to your ISP, contact them before resetting.

5. What Should I Do If 192.168.100.1 Won’t Open?

If the page does not load, try these steps.

1) Check cables and Wi-Fi connection

Make sure your device is connected to the correct modem/router network. If using Ethernet, confirm the cable is firmly plugged in and the LAN light is on.

2) Make sure your device gets an IP address automatically

Most people should use automatic IP settings (DHCP). If your computer is using a manual/static IP, the login page may not work.

3) Confirm the IP address is correct

Some devices do not use 192.168.100.1. Your modem/router may use 192.168.1.1, 192.168.0.1, or 10.0.0.1 instead. Check the label on the device.

4) Check if the port number changed

Most devices use the normal web port. But some use a different port. If the port changed, you must include it like this:

• 192.168.100.1:8080

5) Disable proxy or VPN in your browser

Proxy settings, VPN tools, or “auto-dial” settings can prevent access to local IP addresses. Turn these off and try again.

6) Check IP or MAC binding rules

Some routers limit which devices can log in (MAC binding or access control). If your device is blocked, you may not be able to open the login page.

7) Reset only if necessary

If you cannot find the management IP or port, a reset can restore defaults. But if the device is ISP-owned (fiber modem/ONT), resetting may stop your internet. Contact your ISP first if you are not sure.

6. How Do I Change My Wi-Fi Name (SSID) and Wi-Fi Password?

People change Wi-Fi settings to improve security, stop unauthorized users, or make the network easier to recognize.

1. Log in to your device admin page using 192.168.100.1 (if that is your correct login IP).
2. Find a menu named Wireless, Wi-Fi, WLAN, or Wireless Settings.
3. Change your Wi-Fi name (SSID) and Wi-Fi password.
4. Click Save or Apply.

After you save, your devices will disconnect and must reconnect using the new password.

7. How Do I Change the Router Login IP Address (LAN IP)?

Some devices allow you to change the login IP address. People do this for organization or security. For example, you might change it from 192.168.100.1 to 192.168.2.1.

1. Log in to the admin page.
2. Find LAN Settings, Network Settings, or Local Network.
3. Change the LAN IP address to your new value (example: 192.168.2.1).
4. Save the settings and restart if needed.

After the device restarts, you must use the new IP address to log in.

Tip: If you forget the new IP address, a factory reset will restore the default IP address.

Extra Help for Common Internet Problems

If your internet is not working and you do not want to change advanced settings, these simple checks can help:

• Wi-Fi signal disappeared
• You can see Wi-Fi but cannot connect
• Wi-Fi is connected but there is no internet
• Phone cannot access the internet but Wi-Fi looks normal
• Computer cannot access the internet but Wi-Fi looks normal
• Some devices work online but others do not

Private IP Range Explanation (Simple)

192.168.100.1 is part of a private IP address range used inside home and office networks. Private IP addresses cannot be routed on the public internet, which is why they only work when you are connected to the correct local network.

Invalid IP Formats (Quick Reminder)

If you type the IP address in the wrong format, the login page will not load. Double-check what you type and make sure you are using the correct address for your device.

Below is a list of known device brands and models that use 192.168.100.1 as a default login address.

192.168.100.1 Default Passwords and Usernames

Below are the most common default ONT login credentials in real Chinese broadband environments. They can vary by ISP and device batch, so always check the label on the back/bottom of the ONT first:

• Username: admin Password: admin (older ONTs)
• Username: admin Password: 123456
• Username: user Password: user (limited permissions)
• Username: telecomadmin Password: admintelecom (often seen on China Telecom)
• Username: root Password: admin (some ZTE ONTs)
• Username: CMCCAdmin Password: aDm8H%MdA (some China Mobile models)

Many carriers print the login IP, username, and password on a sticker on the ONT. If the password was changed or is not shown, be careful, because incorrect changes can cause the internet to stop working.

192.168.100.1 Default Usernames and Passwords (General Notes)

192.168.100.1 is widely used in China for ONTs, cable modems, and carrier-custom gateway devices. Unlike typical home routers (192.168.1.1), devices using 192.168.100.1 are often carrier-issued, so default usernames and passwords depend heavily on the brand and model.

Important notes:

• Some devices ship with no default username or password.
• Some devices use fixed weak defaults (for example, admin/password).
• Some devices receive a random password from the ISP after first connection.
• Advanced administrator accounts are sometimes known only by the ISP.

This is a list of all routers of different brands that use 192.168.100.1 as the default login address. Click the router brand to view all routers of that brand, and click the router model to view more router information.

Important Security Tips

• If you are still using default username and password, change them as soon as possible.
• Before changing ISP fiber modem passwords, confirm it will not break remote maintenance or support.
• Never share your modem admin username and password with untrusted people.

Common Problems: Why 192.168.100.1 Will Not Open

Using the wrong protocol

Most fiber modems support HTTP only. If you use HTTPS, you may see certificate errors or a blank page.

The modem is in bridge mode and access is limited

In some bridge setups, you can only access the modem admin page from a specific IP range or by connecting directly to the modem LAN port.

192.168.100.1 Summary

192.168.100.1 (１９２．１６８．１００．１) is a private IPv4 address in the RFC 1918 range (192.168.0.0 to 192.168.255.255). It cannot be accessed directly from the public internet. In many broadband networks, especially in fiber internet setups, 192.168.100.1 is widely used as the admin login page for fiber modems (ONT), cable modems, and some ISP gateways.

Through the 192.168.100.1 web admin interface, users or administrators can view modem status and connection info, and if they have permission, configure LAN, WAN, DHCP, WLAN, PPPoE, MAC binding, port settings, and security options. In many ISP environments, normal user accounts have limited permissions and advanced features may be available only to admin accounts or the ISP.

If 192.168.100.1 will not open, the most common reasons are: you are not on the modem network, you are connected to a downstream router, the IP is typed wrong, the management port changed (for example 8080), browser proxy/cache issues, or the ISP has restricted access. Correctly typing http://192.168.100.1 and ensuring you are on the correct local network are the keys to logging in.

192.168.100.1 is not a “phone-only” or “computer-only” address. Any device (phone, PC, tablet) can access it if it is on the same local network. It does not conflict with 192.168.1.1 or 192.168.0.1, because it is often used to separate modem management from router management, which is common in many home network designs.

192.168.100.1 Usage by Country (Popular ISPs, Common Brands, and Typical Institutions)

Below are practical country notes. The exact brand and admin IP can vary by ISP and model, but these are common patterns seen in fiber and ISP gateway deployments.

192.168.100.1 in China

In China, 192.168.100.1 is mainly used by:

• Carrier-provided fiber modems (ONT)
• ONT + router all-in-one gateway devices
• Fiber modems running in bridge mode

Common brands include:

• Huawei fiber modems (ONT)
• ZTE fiber modems (ONT)
• FiberHome fiber modems (ONT)
• Skyworth carrier-custom ONT devices

Important: Most normal home Wi-Fi routers do not use 192.168.100.1. If you see this address, you are usually accessing the ONT, not the separate router you bought yourself.

In China, all three major carriers use 192.168.100.1 on many fiber modem models:

• China Telecom: Many Huawei and FiberHome ONTs use 192.168.100.1
• China Unicom: ZTE and Huawei ONTs commonly use 192.168.100.1
• China Mobile: Some newer ONT models default to 192.168.100.1

In a bridge-mode setup, the ONT handles the upstream fiber connection, and the router handles PPPoE/dialing and local network sharing. In this case, users often deal with 192.168.1.1 (router) and 192.168.100.1 (ONT) at the same time.

192.168.100.1 FAQ.

1. Is 192.168.100.1 an official website?

No. 192.168.100.1 is not any company’s official website and it is not an internet site. It is a local network management address and can only be opened when you are connected to the fiber modem’s network. You cannot open it from outside the local network.

2. Is 192.168.100.1 the same as 192.168.1.1?

No. 192.168.100.1 is usually for fiber modem management, while 192.168.1.1 is usually for router management. In many China home networks, both can exist at the same time, but they do different jobs.

3. Why does logging into my router redirect me to 192.168.100.1?

This usually means you are opening the fiber modem’s admin page, not the router’s admin page. The modem is upstream in the network, so it may respond to your request first. This is very common in bridge mode setups.

4. Can I log in to 192.168.100.1 on my phone?

Yes, as long as your phone is connected to the modem network or the network behind it. Turn off mobile data so the phone uses the LAN. It is better to use a normal browser instead of an in-app browser.

5. Why does 192.168.100.1 not open even though the internet works?

The ISP may restrict access to the modem admin page or disable the web port. In some network designs, you must connect directly to the modem LAN port to open the page. Check your default gateway first.

6. Is 192.168.100.1 only used in China?

No. It is a global private IP address. It is just very common in China because fiber internet is widely deployed, and many ONT models use this address.

7. What if I forgot the 192.168.100.1 login password?

If it is a fiber modem, it is usually not recommended to factory reset it by yourself. Resetting may break your broadband configuration and you may lose internet until the ISP reconfigures it. It is safer to contact ISP support.

8. What is the difference between admin and user accounts on a fiber modem?

The admin account usually has the highest permission. The user account is often limited and may only show basic status information. Many ISP devices restrict advanced settings to admin or ISP-only accounts.

9. Can I change the 192.168.100.1 login address?

Some devices support it, but many ISP-custom devices lock this option. Changing it can cause problems with maintenance or access. In many cases, it is better not to change the management IP.

10. Can I change the Wi-Fi password using 192.168.100.1?

If your fiber modem includes Wi-Fi, you may be able to change the Wi-Fi name and password in the modem admin panel. If you use a separate router for Wi-Fi, you must change the Wi-Fi password in the router admin page instead.

11. Do China’s three major ISPs all use 192.168.100.1?

It is not a single official rule, but in real deployments many models used by China Telecom, China Unicom, and China Mobile use 192.168.100.1. Because they use similar device vendors, this address appears very often in homes.

12. Why do some homes use 192.168.100.1 and others use 192.168.1.1 on the modem?

This depends on the modem model, firmware version, and whether routing mode is enabled. Older or routing-type ONTs often use 192.168.1.1, while bridge-type or newer ONTs often use 192.168.100.1. Both are common and normal.

13. Is 192.168.100.1 only for fiber modems?

In China home networks, it is almost always used for fiber modems or modem-router combo devices. Normal home routers rarely use 192.168.100.1 as their default admin address. If you see it, you are probably looking at the modem.

14. Why does 192.168.100.1 show a timeout?

The most common reason is that your device is not on the modem network. You may be connected to a downstream router, guest Wi-Fi, or another network segment. Another reason is that the ISP restricts access unless you connect directly to the modem LAN port.

15. If my router is doing PPPoE, can I still access 192.168.100.1?

Often yes, but it depends on routing rules. Some routers automatically add a route to reach the modem subnet. If you cannot access it, you may need to add a static route to the 192.168.100.0/24 network on your router.

16. Will 192.168.100.1 conflict with a router using 192.168.1.1?

Usually not, because they are different subnets. 192.168.100.1 is in 192.168.100.0/24, while many routers use 192.168.1.0/24. Using different subnets is one reason ISPs choose 192.168.100.1.

17. What does “insufficient permissions” mean in the modem admin page?

It usually means you logged in with a limited account (such as user) instead of an admin account. In China, ISP devices often separate permissions into user and admin or telecomadmin accounts.

18. Can I switch the modem to bridge mode from 192.168.100.1?

It depends on the device and ISP policy. Some models allow it with an admin account, but many ISP devices lock bridge mode controls. Changing this incorrectly can break your internet connection.

19. Can changing settings in 192.168.100.1 affect all devices in the home?

Yes. The fiber modem is upstream, so changes can impact the entire home network. Incorrect changes to PPPoE, VLAN, or MAC binding can cause a full internet outage.

20. Why do settings sometimes reset after rebooting the modem?

Some ISP devices sync configuration from the ISP system after reboot. Even if you change settings, the modem may restore the ISP profile. This is common for stability and remote support.

21. Why can I ping 192.168.100.1 but the login page will not load?

This means the modem is reachable on the network level, but the web management service is not responding. The web port might be disabled, restricted, or allowed only from certain IPs.

22. Does 192.168.100.1 support HTTPS?

Most China fiber modems support HTTP only. Using HTTPS may cause certificate warnings or a failed connection. Use http://192.168.100.1 unless the device clearly supports HTTPS.

23. Can I use an ISP app instead of opening 192.168.100.1?

Some ISPs provide official apps for basic broadband management. These apps often control the modem through the ISP backend, not by directly opening 192.168.100.1. Advanced settings are usually still handled through the web admin page.

24. Can I see connected devices in 192.168.100.1?

It depends on whether the modem is doing routing. If the modem is in bridge mode, it usually cannot show the downstream device list. If it is routing and providing DHCP, it may show some connected devices.

25. Will visiting 192.168.100.1 leak my privacy?

No, because 192.168.100.1 is a local network address and does not require the public internet. The main risk is sharing your admin password with others, so do not share it with untrusted people.

26. After factory reset, will the modem still work?

In most cases, not immediately. Resetting removes ISP configuration parameters. The ISP may need to push settings again remotely, or support may need to help you reconfigure it.

27. Why do some tutorials say 192.168.100.1 is “only for phones”?

That is a misunderstanding. 192.168.100.1 is not tied to a device type. Phones, computers, and tablets can all open it if they are connected to the correct local network.

28. Can I change 192.168.100.1 to another address?

Some devices can, but in China it is usually not recommended. ISP devices often rely on fixed addresses for maintenance. Changing it can make management difficult or cause settings to be restored automatically.

29. If 192.168.100.1 will not open, what should I do first?
