IP: 172.16.0.1 Login Page Username Password

As we have said above, 172.16.0.1 is the login address for managing router settings, so what should I do if 172.16.0.1 cannot open the router's login page? Here we will introduce the reasons and solutions for the inability of 172.16.0.1 to access the router's administration interface when using a computer to setup routers. You can try the following methods if encountering similar problems.

The reasons why 172.16.0.1 cannot open the router's setup interface can be roughly divided into the following 5 points:

(1) Improper local IP of the computer

If you have set the local IP of the computer before, but because of improper settings, it will lead to the problem that you cannot log in to the router. The solution is to set the IP address of the computer to be obtained automatically. The following takes Win10 system as an example to teach you how to set the local IP as automatic acquisition.

• a. First, right-click the "Start" button of Win10→ select "Network Connections" and open it.
• b. Right-click "Local Area Connection" and select "Properties" to open.
• c. Then select "Internet Protocol Version 4 (TCP/IPv4)" and continue to click "Properties".
• d. Finally, select "Obtain an IP address automatically" → "Obtain DNS server address automatically" → click "OK".

If the computer's IP address has not been set before, and it is automatically obtained by default, you can ignore this problem.

(2) Router connection problem

Use the network cable to connect the computer, modem and router correctly, as shown below:

Connect the external telephone line or optical fiber to the modem first, and then use the network cable to connect the modem to the WAN port of the router. A laptop or mobile phone can be directly connected to the router through WIFI. If it is a desktop computer, you need to use a network cable to connect the router's LAN port to the computer.

(3) Network cable problem

If there is a problem with the network cable used to connect the computer to the router, such as a bad cable or aging crystal head, then 172.16.0.1 will certainly fail to open router's setup interface, so you must make sure the cable is available for normal use. If you have spare cables at home, you can replace it with an intact one, plug it in tight, and then try again to see if using 172.16.0.1 can log in to router's setup page. In addition, if there is a problem with the network cable, you can see the network icon in the lower right corner of the computer will display abnormally.

You can pay attention to the icon or directly run "Ping 172.16.0.1" through CMD command on the computer to see whether the connection between the computer and the router is normal.

(4) URL input error in browser

Many browsers have large search boxes in their home page (such as Google, Bing, Baidu, etc.), and people are used to entering 172.16.0.1 in the search box, which is definitely not to open the login page. The correct location to enter 172.16.0.1 should be the address bar in the browser, that is, the top of the browser, where the URL is displayed. The correct position is shown in the following figure:

(5) Router setup problem

Some users mistakenly believe that the IP addresses of all routers are 172.16.0.1, but in fact, not all routers'default login IP is 172.16.0.1, the address may vary with different brand and model routers. If the IP address of your router is not 172.16.0.1 at all, then you will definitely not be able to open the router's setup page with this IP. Therefore, you need to confirm whether the IP address of your router is 172.16.0.1, which can be found at the default IP address (URL) information on the bottom label of the router.

Another situation is that the router's default IP address has been modified. Some users may initially modify the default address of the router in order to increase the security of the router, and after the modification, 172.16.0.1 will not work, you need to use the modified login address. To view the real login address of the router, please check following steps:

• a. Right-click the "Start" button of Win10 → select "Network Connections" to open.
• b. Right-click "Local Area Connection" → select "Status" to open.
• c. Click "Details".
• d. Find the IP address behind "IPv4 Default Gateway", which is the real login IP of the router.

The above are the common reasons and solutions for 172.16.0.1 unable to open the router's setup interface. If you have checked all the previous problems and still cannot open it, you can reset the router to factory settings first, and then try to log in again. For the method of resetting the router to factory settings, please refer to: How to restore the factory settings of routers using 172.16.0.1 as the login address?

Entering 172.16.0.1 in the browser's address bar should show the router's login interface, but finally the login interface of the Internet Service Provider (ISP) is displayed. What is the reason? What is the login address of the router and how to enter the login interface of the router?

If your router's administration address is indeed 172.16.0.1, but it opens the ISP's broadband login interface, it may be due to the following reasons:

(1) There is an IP address conflict between the router and modem

The default IP address of the modem provided by the ISP is 172.16.0.1, and the IP address of the router is also 172.16.0.1. At this time, there is an IP address conflict, which may lead to open 172.16.0.1 appearing the ISP's broadband login interface.

Solution: modify the IP address of the router as follows:

• a. First, unplug the network cable connecting the WAN port of the router to the modem, and only connect the computer to the LAN port of the router. As shown below:


Important note:

Don't worry that there is no way to set up the router if your computer can't access the Internet after unplugging the router's WAN port network cable. Because when setting up the router, you don't need the computer to be able to access the Internet, just connect your computer to the LAN port of the router with a network cable, or connect your laptop/mobile phone to the router through WIFI, and you can open the setup page to configure the router.

• b. Enter 172.16.0.1 in the address bar of your browser to log in to the router's setup page.
• c. On the router's setup page, find "LAN port setup" (some routers also called "LAN setup" or "Internal network setup"), and modify the IP address (for example, modify it to: 192.168.2.1), as shown in the following figure:

• d. After modifying the IP address of the router, connect the WAN port of the router to the modem. Then use the modified IP address to open the login interface of the router.

(2) The IP address of the router has been modified

If the user does not know the router's IP address has been modified, and still enters the default 172.16.0.1, the ISP's login page may appear.

Solution: enter the modified IP address to open the login interface of the router. We can determine the real IP address of the router by checking computer's local connection (Ethernet) address. As shown in the figure below, the IP address behind the IPv4 default gateway is the real IP address of the router.

That is, now you need to enter 192.168.3.1 in the browser to open the router login interface.

Note:

① The login IP address of the router can be modified manually.

② At present, some routers have the function of automatically modifying the IP address. When the WAN port of the router is connected to the modem, the router automatically detects that its own IP address is the same as modem's, and the router will automatically modify its own IP address, so as to avoid conflict with the modem's IP address.

With so much introduced above, you may be wondering which brands of routers use 172.16.0.1 as the default login address and what are their default usernames and passwords. This site has collected the default login usernames and passwords for commonly used router brands and models on the market. The following is a list of usernames and passwords for routers using 172.16.0.1 as the login address. We have analyzed them according to the availability rate, and the data is for reference only. If no list is displayed, it means that this site has not yet collected this IP used as a default login address by router.

• b. After successfully logging in to the router's administration settings interface, click "Advanced"→"Administration"→"Set Password".
• c. Enter the old password and new password, and then apply them.

Note：

After changing the administrator login password of the router, you can successfully log in only when you enter the modified password correctly. Therefore, you must remember the modified password. It is best to use a sticky note to record it and paste it to the back of the router to avoid forgetting the password and being unable to log into the router.

(2) How to change the wireless network password (WIFI password)?

Changing the wireless network password (WIFI password) is similar to changing the router's login password, you also need to log in to the router's administration page to change.

• a. Log in to the administration page of the router (refer to question 1：How to use 172.16.0.1 to log in to the router's administration page?）。
• b. After successfully logging in to the router's administration settings interface, click "Advanced" → "Setup" → "Wireless Setup" and select "WPA-PSK/WPA2-PSK".
• c. Enter the PSK password (WIFI password) and then apply it.

3 authentication types: automatic selection, WPA-PSK, WPA2-PSK. There is basically no difference between the 3 types. Just select automatic.

3 encryption algorithms: automatic selection, TKIP, AES. AES encryption algorithm is generally recommended.

If the router settings are messed up and can't access the Internet normally, how to reset the router and restore the factory settings by using 172.16.0.1 to log in to the router administration page? Generally speaking, there are 2 ways to restore factory settings: restore factory settings on the router's administration page and directly press and hold the RESRT button on the router.

（1）How to restore factory settings on the router's administration page?

• a. Log in to the administration page of the router (refer to question 1：How to use 172.16.0.1 to log in to the router's administration page?）。
• b. After successfully logging in to the router's administration settings interface, click "Advanced" → "Administration" → "Backup Settings".

• d. Click the "OK" button, the router will reboot automatically. After reboot, the router will be restored to factory settings.

This method can only be operated under knowing the router's username and password. If you have forgotten them, don't worry, we have another method to reset the router, let's go ahead.

(2) How to reset the router to factory settings by pressing the RESET button?

• a. Find the RESET button on the back of the wireless router. This button generally has two forms, one is a protruding button that can be pressed directly, and the other is a small hole shaped button, which requires a paper clip, pin and other fine-pointed objects to be inserted into the hole and pressed continuously.



• b. The router is powered on and the power indicator remains on.
• c. Press and hold the RESET button for about 10 seconds and then release it. All the indicators are on and then all off. After waiting for a few seconds, the router starts working again, which means it has been restored to the factory setting successfully.

Note：

① The router cannot be powered off when restoring to factory settings. Otherwise, it may damage the router's hardware.

② After the router is restored to factory settings, all settings will be lost. You need to set up the router again to access the Internet normally, so please be cautious to restore factory settings.
