How to Change Your Wi-Fi Password on Any Home Router

Changing your Wi-Fi password is one of those small jobs that pays off immediately. Maybe a neighbour you shared it with years ago is still connected, maybe an old flatmate’s devices keep reappearing, or maybe your password is still the string of random characters printed on the router that nobody in the house can remember or type correctly. Whatever the reason, setting a fresh, strong password that you chose yourself improves both security and convenience, and the whole process takes about ten minutes once you know where the setting lives.

This guide covers the change on a typical home router through the browser admin page, then explains the app-based route used by many newer routers and mesh systems, what security mode to pick alongside the new password, and what happens to your phones, laptops, TVs, and smart home gadgets afterwards. The steps are written generically so they apply to TP-Link, Netgear, ASUS, Linksys, D-Link, and most provider-supplied routers, with the menu names you are most likely to see.

Before You Change It: A Few Decisions

Choose the new password before you open any settings. Aim for at least twelve characters, ideally a passphrase of three or four unrelated words combined with a number or symbol, such as a phrase only your household would think of. Avoid names, birthdays, addresses, and anything already used on another account. A password manager can generate and store one for you, but remember that guests and family members will need to type this on TVs and games consoles, so a memorable passphrase usually beats a random string.

Also decide whether to change the network name, or SSID, at the same time. You do not have to, and keeping the same name means devices only need the new password rather than a whole new network. If your current name reveals your surname or router model, though, this is a good moment to switch to something neutral. Finally, note that changing the password will disconnect every wireless device at once. Warn the household, and if you work from home, do it outside meeting hours.

Step-by-Step: Change the Password in the Router Admin Page

Step 1: Connect and Log In

Connect a computer to the router, preferably with an Ethernet cable so you stay connected when the Wi-Fi settings change, and open the admin page at 192.168.0.1 or 192.168.1.1. Sign in with the administrator username and password. If this is your first time, those are the defaults printed on the router sticker, commonly admin and admin on older hardware. If you need a refresher on this part, our detailed walkthrough on accessing your router admin page for the first time covers every brand’s address and login quirks.

Step 2: Find the Wireless Security Settings

Look for a menu called Wireless, Wi-Fi, or Wireless Settings, then a sub-section named Wireless Security, Security, or Password. On TP-Link routers it is usually Wireless, then Wireless Security on older interfaces, or Advanced, Wireless, Wireless Settings on newer ones. On Netgear it sits under Wireless or Setup, Wireless Settings. Dual-band routers show separate sections for the 2.4GHz and 5GHz bands, and many let you apply the same password to both, which is what most households should do so devices can move between bands without confusion.

Step 3: Set the Security Mode and New Password

Set the security mode or authentication type to WPA2-PSK (AES) as a minimum, or WPA3 or WPA2/WPA3 mixed mode if your router and devices support it. Avoid WEP entirely and avoid WPA with TKIP, because both are broken or heavily weakened standards that modern devices warn about. The Google Nest help pages on Wi-Fi security standards give a clear plain-language summary of why WPA2 and WPA3 are the right choices for home networks.

Type the new password into the field labelled Password, Wireless Password, Pre-shared Key, or Network Key. Some interfaces hide it behind a show characters option, which is worth using so you can proofread it before saving. Type it slowly and check capital letters, because the password is case-sensitive.

Step 4: Save, Reboot, and Reconnect

Click Save or Apply. The router may reboot, and every wireless device will drop off the network within a minute. This is expected. On each phone, laptop, and tablet, select your network, choose Forget if it keeps trying the old password automatically, then join again with the new password. Wired devices are unaffected. Go room by room through smart TVs, streaming sticks, printers, cameras, and smart speakers, because anything left on the old password will quietly sit offline until you update it.

Changing the Password Through a Router App

Many current routers and almost all mesh systems are managed from an app instead: TP-Link Tether or Deco, Netgear Nighthawk or Orbi, ASUS Router, Linksys, or your provider’s app. The flow is similar in all of them. Sign in to the app while connected to your home network, open the Wi-Fi settings or network settings page, edit the password field, and save. The app pushes the change to the router and usually shows a list of devices reconnecting. If your system has band steering with a single network name, there will be one password field for the whole network, which makes the job simpler still.

One app-specific caution: some apps require your cloud account password, such as a TP-Link ID, before letting you change security settings. That is an extra protection layer, not an error. If you have forgotten the cloud password, reset it through the app’s email recovery rather than resetting the router itself.

What About the Guest Network?

If your router offers a guest network, change its password too, or disable it if nobody uses it. The guest network is the one you should hand out to visitors, because it keeps them off your main network and away from shared folders, printers, and smart devices in many configurations. A sensible routine is a strong permanent password for the main network that rarely changes, and a simpler guest password you rotate whenever you feel too many people know it.

Common Mistakes and Tips

The classic mistake is changing the administrator password when you meant to change the Wi-Fi password, or the reverse. They live in different menus: the Wi-Fi password sits in the wireless settings, while the admin password sits in system tools, administration, or management. Changing the wrong one leaves the network exactly as exposed as before while locking in a false sense of security.

Another frequent problem is updating the password on the 2.4GHz band but not the 5GHz band, so half the house keeps working and half does not. Work through both sections, or use the sync option if your router offers one. People also lose the new password within a day because they never wrote it down. Store it in a password manager and keep a paper copy somewhere sensible at home.

A practical tip for a smooth changeover: keep the old network name, change only the password, and have the new password open on your phone screen as you walk around reconnecting devices. Start with the devices you rely on most, such as work laptops and phones, and leave rarely used gadgets for last. If a stubborn older device refuses to join, check whether it only supports WPA2 and adjust a WPA3-only setting back to mixed mode.

Conclusion

Changing your Wi-Fi password is a short, high-value piece of home network housekeeping. Log in to the router, find the wireless security section, pick WPA2 or WPA3, set a long passphrase you can actually remember, save it for both bands, and reconnect your devices one by one. Do it once properly and you gain a network that only your household can use, a password everyone can type without reading a sticker under a desk, and one less thing to worry about every time a device you do not recognise appears online.

Frequently Asked Questions

Will changing my Wi-Fi password kick off unknown devices?

Yes. Every device must sign in again with the new password, so anything belonging to a neighbour, ex-tenant, or stranger who somehow learned the old password is locked out until they get the new one, which they will not.

How often should I change my Wi-Fi password?

There is no fixed schedule. Change it when someone who should no longer have access knows it, when a device is lost or stolen, or if you suspect it has been shared too widely. A long, unique password matters more than frequent changes.

Why do my devices keep saying the password is incorrect after I changed it?

Usually the device is still trying a saved copy of the old password, or there is a typo with capital letters or similar characters. Use the Forget This Network option, then join fresh and type the password carefully.

Should I use WPA2 or WPA3?

Use WPA3 if all your devices support it, or the WPA2/WPA3 mixed mode if some older gadgets struggle. Never use WEP or the original WPA with TKIP, as both can be cracked quickly with widely available tools.

Does changing the Wi-Fi password change the router admin password?

No. They are separate credentials in separate menus. For good security you should set both: a strong Wi-Fi password for joining the network and a different strong admin password for changing its settings.
