How to Change Your Modem Password

Modem Password vs WiFi Password

These are two different passwords and people confuse them constantly. The modem password (also called the admin password) lets you log into the modem’s settings panel. This is the one your internet provider set up, usually with a default like “admin/admin” or “admin/password.” The WiFi password is what devices use to connect to your wireless network. You can change both from the same admin panel, but they serve different purposes.

Changing the admin password prevents anyone on your network from accessing your modem’s settings and messing with your configuration. Changing the WiFi password controls who can connect to your network. If you’ve never changed either, you should change both.

How to Access Your Modem’s Admin Panel

1. Connect to your modem either through WiFi or with an Ethernet cable plugged directly into the modem. An Ethernet connection is more reliable for this.
2. Open a web browser on your computer or phone.
3. Type your modem’s IP address into the address bar (not the search bar). The most common addresses are 192.168.0.1 or 192.168.1.1. If neither works, check the sticker on your modem – the default gateway address is usually printed there.
4. A login page appears. Enter the default admin username and password. Check the sticker on your modem for these, or try the common defaults listed below.

Default Login Credentials by Brand

If the default credentials don’t work, someone may have changed them before (or your ISP set a unique password during installation). Look for a sticker on the bottom or back of the modem – many ISPs print the admin login directly on the device. If you still can’t get in, a factory reset restores the defaults (more on that below).

How to Change the Admin Password

1. Log into your modem’s admin panel using the steps above.
2. Look for a section called “Administration,” “Management,” “System,” or “Maintenance.” The exact label depends on your modem brand.
3. Find the password or account settings option.
4. Enter your current password, then type your new password twice to confirm.
5. Click Save or Apply. The modem may reboot.
6. Write down the new password and store it somewhere safe. If you forget the admin password, the only recovery option is a factory reset.

Use a strong password – at least 12 characters with a mix of letters, numbers, and symbols. Don’t reuse a password you use for email, banking, or other accounts. A password manager makes this easy to track.

How to Change the WiFi Password

1. Log into your modem’s admin panel.
2. Find the “Wireless,” “WiFi,” or “Wireless Settings” section.
3. Look for “Security” or “WPA/WPA2 Settings.” You may see separate settings for 2.4 GHz and 5 GHz bands – change the password for both.
4. The current WiFi password appears in a field labeled “Passphrase,” “Pre-Shared Key,” “Network Key,” or “Password.”
5. Delete the old password and type your new one.
6. Make sure the security mode is set to WPA3 or WPA2-PSK (AES). Never use WEP – it’s outdated and easily cracked.
7. Click Save or Apply.

After changing the WiFi password, every device connected to your network gets disconnected. You’ll need to reconnect each device (phones, laptops, smart TVs, smart home devices) using the new password. This is normal and expected – it’s actually the point if you’re changing passwords because you suspect someone unauthorized is on your network.

How to Find Your Modem’s IP Address

If 192.168.0.1 and 192.168.1.1 don’t work, you can find your modem’s exact IP address from your computer’s network settings.

On Windows:

1. Press Windows + R to open the Run dialog.
2. Type “cmd” and press Enter to open Command Prompt.
3. Type “ipconfig” and press Enter.
4. Look for “Default Gateway” under your active network connection. That IP address is your modem.

On Mac:

1. Click the Apple menu and go to System Settings, then Network.
2. Click your active connection (WiFi or Ethernet).
3. Click Details or Advanced.
4. The “Router” field shows your modem’s IP address.

On iPhone or Android:

1. Go to Settings, then WiFi.
2. Tap the info icon (i) next to your connected network.
3. Look for “Router” or “Gateway.” That’s your modem’s IP.

What to Do If You’re Locked Out

If you’ve forgotten the admin password and the default credentials don’t work, a factory reset is your only option. Every modem has a small reset button (usually recessed, requiring a paperclip or pin to press) on the back or bottom. Hold the button for 10 to 15 seconds while the modem is powered on. The modem restarts and all settings return to factory defaults, including the admin password.

Be aware that a factory reset erases all your custom settings: WiFi name, WiFi password, port forwarding rules, DNS settings, and any ISP-specific configuration. After the reset, you’ll need to set everything up again. If your ISP configured the modem during installation, you may need to call them to restore internet service after a factory reset.

How often should I change my modem password?

Change the admin password once after initial setup and then only if you suspect it’s been compromised. Change the WiFi password whenever someone who shouldn’t have access knows it – after a roommate moves out, when you stop trusting a neighbor you shared it with, or if you notice unfamiliar devices on your network. Routinely changing passwords every 90 days isn’t necessary for home networks unless you have a specific security concern.

Will changing my modem password affect my internet speed?

No. Changing either the admin password or the WiFi password has zero effect on your internet speed. Your connection speed is determined by your ISP plan, your modem’s capabilities, and your local network conditions. If your internet is slow, changing passwords won’t fix it – check for bandwidth-heavy devices, WiFi interference, or contact your ISP about your connection quality.

Can my ISP see my modem password?

Your ISP can access ISP-provided modems remotely in most cases. They can see and reset the admin password, view your WiFi settings, and push firmware updates. If you use your own purchased modem, the ISP typically doesn’t have remote access to its admin panel. For maximum privacy and control, use your own modem and router rather than renting from your ISP.
