How to Change Your Wi-Fi Password on Any Router

Updated November 2, 2026 · 6 min read

Changing your Wi-Fi password is the single fastest security upgrade you can make at home. It kicks off neighbors piggybacking on your connection, locks out ex-roommates, and stops the mystery devices slowing your network down. It takes about five minutes on any router — Netgear, TP-Link, Linksys, ASUS, your ISP's gateway, all of them. Here's exactly how.

Step 1: Find your router's login page

Your router has a web page for its settings. The address is almost always one of these:

• 192.168.1.1 (most common — Netgear, Linksys, ASUS)
• 192.168.0.1 (TP-Link, D-Link)
• 10.0.0.1 (some Xfinity/Comcast gateways)

Not sure? On Windows, open Command Prompt and run:

ipconfig

Look for Default Gateway — that's your router's address. On a Mac: System Settings → Wi-Fi → Details on your network → the Router field. On iPhone/Android, the gateway is shown in the Wi-Fi network details.

Type that address into your browser's address bar (not a search engine). Some ISP gateways also have a custom address like routerlogin.net or mywifiext.net — check the sticker on the router.

Step 2: Log in to the router

You'll be asked for a username and password. If you've never changed these, use the defaults — they're printed on a sticker on the router (usually on the bottom or back). Common defaults:

• Username admin, password password
• Username admin, password admin
• Username and password both printed on the sticker (many newer routers use a unique random password)

Changed it once and forgot it? Hold the router's reset button for 10–15 seconds with a paperclip to factory-reset it — but know this wipes all your settings, so you'll need to set up Wi-Fi names and passwords from scratch. For ISP gateways (Xfinity, Spectrum, AT&T), you can often log in with your ISP account credentials instead, or manage Wi-Fi from the ISP's app without the admin password at all.

While you're in here: if the admin password is still the default, change that too. Anyone on your network with the default password can change your settings.

Step 3: Find the wireless settings

The menu name varies by brand, but it's always some version of the same thing:

• Netgear: Wireless (left sidebar)
• TP-Link: Wireless → Wireless Security
• Linksys: Wi-Fi Settings
• ASUS: Wireless → General
• Xfinity gateway: Connection → Wi-Fi

If your router has separate 2.4 GHz and 5 GHz sections, you'll set a password for each. Using the same password for both is fine and makes life easier — just keep the network names distinct if you want to control which band each device uses.

Step 4: Set the new password

1. Find the Password, Passphrase, or Pre-Shared Key field.
2. Type your new password. Aim for at least 12 characters — a short phrase with numbers and a symbol is both strong and memorable (e.g. correct-horse-battery-staple style, but pick your own).
3. Set Security mode to WPA2-Personal (AES) at minimum. If your router offers WPA3, use it — but only if all your devices are from the last few years, since older gadgets can't connect to WPA3-only networks. There's usually a WPA2/WPA3 mixed mode that's the best of both.
4. Click Save or Apply. The router may reboot — that's normal.

Avoid: your name, address, phone number, birthdays, pet names, or anything guessable. And don't reuse a password you use for an account — if someone cracks your Wi-Fi, they shouldn't get your email too.

Step 5: Reconnect all your devices

Everything that was on your Wi-Fi is now offline — phones, laptops, TVs, game consoles, smart speakers, thermostats, doorbells, the works. Reconnect them one by one with the new password. Budget 10–15 minutes for this; smart home gadgets are the tedious part, since many need to be re-added through their own apps.

Pro tip: do this on a quiet evening, not five minutes before a work video call. And write the new password down somewhere safe (a password manager is ideal) — you'll need it again the next time a guest asks.

Tips: guest networks and keeping it strong

• Set up a guest network for visitors instead of handing out your main password. Most routers have a Guest Network toggle in the wireless settings — give it a simple password and keep your main one private.
• Don't share your main password casually. Every device with it can see other devices on your network.
• Change it after big life changes — roommates moving out, breakups, Airbnb guests, a contractor who needed access. Two minutes of work buys real peace of mind.
• Check who's connected. Most router apps show a device list. Unknown devices you can't account for mean it's time to change the password (and check for a neighbor who's a little too friendly).

A slow network with mystery devices on it might not be slow at all — it might just be crowded. If speed is the real complaint, our guide to fixing slow Wi-Fi speed will help you find out.

Frequently asked questions

Will changing my Wi-Fi password kick everyone off?

Yes — every device must reconnect with the new password, including smart home gadgets. That's the point: anyone you don't re-authorize stays off. Plan for 10–15 minutes of reconnecting.

What's the difference between the Wi-Fi password and the router admin password?

The Wi-Fi password (network key) is what devices use to join your wireless network. The router admin password is what you use to log into the router's settings page. They're different credentials — and you should change both if either is still set to the factory default.

Should I use WPA2 or WPA3?

WPA3 is stronger, but some older devices (pre-2018 phones, old printers, cheap smart plugs) can't connect to WPA3-only networks. The WPA2/WPA3 mixed or "transition" mode is the sweet spot for most homes: modern devices get WPA3, old ones fall back to WPA2.

I can't log into my router — what now?

First, double-check the default credentials on the router's sticker. If you changed the admin password and forgot it, factory-reset the router (hold the reset button 10–15 seconds) — you'll set everything up fresh. If it's an ISP gateway, try your ISP's app; Xfinity, Spectrum, and AT&T all let you change Wi-Fi passwords without touching the admin page.
