Change your wireless network password MacBook — a task that often baffles users due to the peculiarities of the operating system architecture macOSIt's important to understand a fundamental principle right away: your laptop doesn't generate a Wi-Fi signal on its own; it only connects to the router, which then distributes the internet. Therefore, changing the network password (which you enter when connecting new devices) directly through the Wi-Fi settings in the MacBook menu is impossible. To do this, you'll need to access the router's interface, which is accessible through a web browser.
However, there is a second aspect to this task - managing saved passwords. If your goal is to delete the old key Whether you want to access the password your MacBook automatically remembers or view a forgotten password for your current network, all the necessary tools are already in the system. In this article, we'll cover both scenarios in detail: how to access the router settings to change the global password and how to manage saved credentials in Apple Keychain.
Understanding the difference between these two processes is critical to properly configuring your home network security. Incorrect actions can result in loss of internet access on all devices or, conversely, leave the network vulnerable to intruders. We'll cover the current interfaces. macOS Sonoma And macOS Sequoia, as well as universal methods for logging into the admin panels of popular routers.
Why can't I change my network password in the WiFi settings?
Many users mistakenly believe that there should be a "Change Password" button in the system settings section where the connection status is displayed. Logic dictates that once the device is connected, it can control everything. However, security protocol wireless communication is designed differently. Your MacBook In this connection, the router acts as a client, not a server. It requests access, and the router either grants it or blocks it.
Attempting to change network settings on your computer will result in nothing more than a disconnected connection if you force-forget the network. The router will continue to broadcast a signal with the old encryption key. To change this key, you must send a command directly to the device broadcasting the signal. This is done through a special web menu, hidden from the regular user but accessible via a specific IP address.
⚠️ Note: If you change the password in your router settings, your MacBook and all other devices will immediately lose internet connection. You will have to re-enter the new password manually on each device.
There is only one exceptional case when a MacBook can act as an access point - the mode Internet Sharing (Shared Internet). In this situation, the laptop shares its internet connection via Wi-Fi, and the password is then set in macOS settings. However, this is a highly specialized scenario and is not standard for home use.
Preparing to change your router password using a MacBook
Before you begin setting up your device, you need to make sure it has a stable connection to the router. It's best to perform these steps by connecting your MacBook to the router via LAN cable (Ethernet) if you have an adapter, as the WiFi network may temporarily drop while changing settings. If you don't have a cable connection, make sure your current Wi-Fi signal is stable.
You'll need to know the IP address of your default gateway. This digital address is the gateway to the "brain" of your network. macOS This can be done very quickly through the system settings. Also, prepare your login and password for accessing the router's admin panel. If you've never changed them, they're most likely the default ones (often this is admin/admin or indicated on the sticker on the bottom of the device).
Modern routers from different manufacturers (TP-Link, ASUS, Keenetic, MikroTik) have their own interface features, but the access principle remains the same. It's important not to confuse the WiFi password (which we change) and the web interface password (which protects the settings from being changed). They are often the same by default, but for security reasons, it's best to distinguish them.
How to find a router's IP address on macOS
The first step is to find the exact address where the Control Panel is located. The path to this information may vary slightly across different versions of macOS, but the steps are the same. Open the Apple menu (the apple in the upper left corner) and select System Preferences (System Settings).
In the window that opens, find the section Net (Network). If you're connected via Wi-Fi, click your network name or the "Details" button. If you're using a cable, select Ethernet. In the menu that opens, scroll down to the TCP/IP section. We're interested in the line Router (Router). It is this set of numbers (for example, 192.168.1.1 or 192.168.0.1) needs to be copied or remembered.
| Router manufacturer | Standard IP address | Standard login | Standard password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| Keenetic | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Xiaomi | 192.168.31.1 | admin | (from the Bundle) |
Once you have received the address, open any browser on your MacBook - Safari, Chrome or FirefoxEnter the resulting numbers in the address bar (not the search bar!) and press Enter. If the address is correct and the connection is stable, the browser will prompt you for authorization. Enter your username and password. If the default ones don't work, they may have been changed previously, and you'll need to reset the router.
Changing the WiFi password in the router interface
Admin panel interfaces can look intimidating due to the abundance of technical jargon, but we only need one tab. Look for sections with titles Wireless (Wireless mode), Wi-Fi, WLAN or Seamless roamingWithin this section, there is always a subsection called "Security" or "Wireless Network Settings".
Find the field called Wireless network password, WPA Pre-Shared Key or Wireless PasswordDelete the current character set and enter a new one. It is recommended to use complex passwords of at least 12 characters, including mixed-case letters and numbers. This will protect your network from brute-force attacks.
Pay attention to the encryption type. In modern networks, a standard must be selected. WPA2-PSK or WPA3If you have WEP or WPA (without the "2"), be sure to change the encryption type, as these protocols are outdated and easily hacked. After entering the new password, be sure to click the Save (Save) or Apply (Apply).
⚠️ Note: When saving the settings, the router will reboot the wireless module. The connection on your MacBook will be lost. This is normal. You will need to select your network again from the list of available networks and enter a new password.
Managing saved passwords in iCloud Link
If your goal is not to change the password on the router, but to view the saved key or delete it from the MacBook memory, you will need a utility Bunch of keys (Keychain Access). This is a system tool that stores all passwords, certificates, and access keys. You can find it using Spotlight search (Cmd + Space) and entering the utility's name.
Select a category in the left panel Passwords (Passwords). In the list on the right, find the name of your WiFi network. Double-click it. A properties window will open, where you need to check the box. Show passwordThe system will ask for your macOS account password (or use Face ID/Touch ID). Once confirmed, the password will appear in the text field.
To delete an old or unnecessary password, select the network in the list and press the key Delete on your keyboard or select "Delete" in the Edit menu. Confirm your action. After this, your MacBook will "forget" the network and ask you to re-enter the details the next time you connect. This is useful if you've changed your router but the network name remains the same, and your MacBook is trying to connect using the old details.
In newer versions of macOS (starting with Ventura and Sonoma), you can also manage passwords through System Preferences → PasswordsThe interface here is more user-friendly, similar to iOS. You can find the network in the list, copy the password, or delete it using biometric authentication.
Internet Sharing on a MacBook
There is a situation where the MacBook itself becomes a source of WiFi signal. This mode Public InternetIf you share your wired internet connection with other devices via your laptop's Wi-Fi, the password is changed in the macOS settings, not the router's.
To set up, go to System Preferences → General → Internet Sharing (or just "Sharing" in older versions). Select the connection source (for example, Ethernet) and the transfer method (Wi-Fi). Click the button Wi-Fi settingsIn the window that opens, you can set the network name and install PasswordHere you can also select the security type; WPA2 Personal is recommended.
This method is often used in hotels with only one LAN port, or to create a temporary, isolated network for guests. In this case, your MacBook acts as a mini-router, and all password change rules are applied locally on the device.
Common problems and their solutions
After changing the password, users often encounter problems with their MacBook not seeing the network or seeing the message "Unable to connect." The first thing to do is delete the network profile. Go to Network settings, find your network, click "Forget this network," or delete it through Keychain Access as described above. Then try connecting again.
Another common issue is an IP address conflict or a frozen network service. If simple methods don't help, try resetting your network settings. On macOS, you can do this by deleting configuration files, but a safer method is to create a new one. Location (Location) in the network settings. Name it "Test," apply it, and try setting up a connection in this clean profile.
⚠️ Note: Router interfaces and macOS versions are constantly being updated. Button locations may change. If you can't find a specific option, search for similar terms (Wireless, Security, WLAN).
If all else fails, there may be a problem with the Wi-Fi module drivers or a hardware failure. Try rebooting the router (unplug it for 10 seconds) and the MacBook itself. In 90% of cases, this resolves network settings "sticking" issues.
Can I change my WiFi password if I forgot the current one?
Yes, but only if you have access to the router's admin panel. If you've forgotten both your WiFi password and the password to access the router's settings, the only solution is to physically reset the router using the Reset button. This will restore it to its factory settings (the password is on the sticker), and you can set a new one.
Where are WiFi passwords stored on a MacBook?
All passwords are stored in a secure database. System.keychain or login.keychainAccess to them is protected by your macOS user account password. Without this password, you won't be able to view saved keys using standard tools.
Why is the Internet slow after changing the password?
This may be because your MacBook is trying to connect using an older protocol or channel. Try changing the Wi-Fi channel in your router settings (for example, from 1 to 6 or 11 for 2.4 GHz) or switching to the 5 GHz band if your device supports it.
How to make your password as secure as possible?
Use a phrase of 4-5 random words separated by symbols, or a set of 16+ characters with numbers and special characters. Avoid birthdays, names, and simple sequences (such as 123456). To generate complex passwords, you can use the built-in generator in Keychain Access when creating a new password.
