How to Change the WiFi Password and Name

Changing your WiFi password and name is the fastest way to secure your network and make it easier to recognize. This guide tells you exactly how to update both on the most common routers, step by step, so you don’t get locked out or leave devices behind. If your goal is better security with minimal hassle, follow these instructions and you’ll have the new credentials applied in minutes.

To change your WiFi password and name, log into your router’s settings (usually via a web address or the router app), then update the SSID (WiFi name) and the wireless security settings (password). Save the changes, reconnect your devices using the new WiFi name and password, and confirm internet works—an approach that’s still the most reliable in 2026 because it uses the router’s official configuration flow.

This is for anyone who wants to update their home or small-office WiFi credentials—whether you’re securing a network after sharing access, replacing an old router default, or fixing a confusing WiFi name.

Log in to your router settings

To change WiFi credentials, you first need access to your router’s admin interface—not your WiFi connection credentials. Once you’re signed in, the router settings pages typically expose both the SSID (WiFi name) and the WiFi security password in the same place.

Find the right admin login method

Use the router’s manufacturer documentation (or the sticker/label on the router) to find the admin login method. Most modern routers support either a browser-based login (via a gateway web address) or a dedicated mobile app, and either path leads to the same underlying configuration.

Your WiFi password does not usually authenticate you to the router admin page; the router uses a separate admin username and password.

If your router has a mobile app, it typically acts as a secure gateway to the same settings you’d edit in a browser.

In my experience helping small offices clean up WiFi access after employee changes, the fastest path is using the router’s app (when available) because it reduces the chances of logging into the wrong device on the network.

Sign in and locate the correct settings page

After signing in with the admin username/password, look for menus labeled Wireless, Wi‑Fi, Network, or Advanced Wireless. The SSID and security settings are almost always grouped together under these headings, so you’re not hunting across multiple categories.

A practical way to avoid mistakes is to keep your browser/app session open while you confirm you’re editing the intended WiFi radios (often 2.4 GHz and 5 GHz), because SSID and password fields can differ by band depending on the router model.

Change the WiFi name (SSID)

Updating the WiFi name (SSID) is the part that most directly affects what devices display in their WiFi list. Change it in the router’s Wireless/Wi‑Fi settings, save, and then reconnect devices so they attach to the new name.

Update the SSID field

Find the field labeled SSID, WiFi Name, or Network Name (commonly under Wireless Settings). Replace the current SSID with a clear, consistent name—especially if you manage guest access, IoT devices, or multiple locations.

The SSID (WiFi name) is the label devices use to discover and select a wireless network.

Many routers store SSID settings separately for 2.4 GHz and 5 GHz, which can create differences in device behavior after an update.

Handle 2.4 GHz vs 5 GHz names intentionally

Some routers let you set separate SSIDs per band (e.g., “OfficeWiFi-2G” and “OfficeWiFi-5G”). Other routers mirror one SSID across both. If your devices are picky—common with older smart plugs, some IoT sensors, or certain printers—keeping names distinct can help you control where they connect.

A good operational rule in small offices is: decide whether you want a “single network experience” or “band-specific control,” then mirror that decision everywhere you configure SSIDs. If you change SSIDs inconsistently, you can end up with devices repeatedly disconnecting and re-scanning.

Change the WiFi password

Changing the WiFi password is usually done under the router’s Wireless/Security settings and directly controls who can join your network. For best security in 2026, select WPA3-Personal when your devices support it; otherwise use WPA2-Personal.

Choose a security mode (WPA2 vs WPA3)

In Wireless/Security settings, select the security mode—commonly WPA2-Personal or WPA3-Personal depending on router support. Then enter your new password (often called a WiFi passphrase) and save.

WPA3-Personal uses SAE (Simultaneous Authentication of Equals) as its key establishment method.

WPA2-Personal is typically based on AES-CCMP encryption with a pre-shared key (PSK) passphrase.

According to Wi‑Fi Alliance (2018), WPA3 certification began rolling out starting in 2018, expanding the security improvements over WPA2.

According to IEEE 802.11i (2004), WPA2 is derived from the 802.11i security amendment finalized in 2004.

According to Wi‑Fi Alliance security specifications and technical materials (latest published revisions), WPA2’s CCMP uses AES with 128-bit keys for the CCMP cryptographic operation.

Comparison: which security mode should you pick?

Here’s a clear decision view that’s easier for teams to agree on than debating router screens.

Option	Best for	Trade-off
WPA3-Personal	Modern phones/laptops and newer IoT devices that support WPA3	Some older devices may fail to join if they don’t support WPA3
WPA2-Personal	Mixed device environments that include older WiFi hardware	Less resilient than WPA3 against certain modern threat models
WPA2/WPA3 Mixed Mode	Gradual upgrades where some devices are WPA2-only	Compatibility improves, but you may not get the strictest WPA3-only posture

📋 MANDATORY DATA TABLE

Save the new password and plan for disconnects

After you save the security changes, WiFi clients connected to the old password will disconnect. The goal is simple: once saved, reconnect phones, laptops, and IoT devices using the new WiFi name and new WiFi password.

Changing the WiFi passphrase forces all existing clients to re-authenticate using the new credentials.

If you run a router in a home or small office, plan downtime because every device may briefly lose connectivity.

Apply settings and reconnect your devices

After saving changes in the router admin page, your router applies updates and may reboot. Then you reconnect devices to the updated SSID and enter the new WiFi password.

Wait for the router to apply settings

Most routers show an “applying changes” message and then return to the settings screen once finished. Time varies by model—. If you have critical connections (VoIP phones, POS systems, remote work), schedule the update during a low-traffic window.

Router configuration changes often trigger a wireless service restart, which can briefly drop all Wi‑Fi clients.

The router may preserve the same admin session while restarting Wi‑Fi radios, but clients still need to reconnect.

Reconnect each device (and update smart-home gear)

Reconnect phones and laptops first, because they help you confirm internet access immediately. Then update smart-home devices (cameras, thermostats, plugs) using the new WiFi name and WiFi password—some devices store credentials internally and must be “taught” again.

In offices with inventory scanners or specialty IoT devices, we recommend doing reconnects one group at a time so you can identify which device type struggles with the chosen security mode.

What can go wrong (and how to avoid it)

WiFi updates usually fail for predictable reasons: admin login mix-ups, device compatibility mismatches, or SSID/policy confusion across 2.4 GHz vs 5 GHz. If you follow a systematic reconnect approach, the risk is manageable.

You can’t log in to the router admin page

If you can’t reach the router’s admin interface, the most common issue is using the WiFi password instead of the admin username/password. The second most common issue is being disconnected from the network you’re trying to manage (or being on a different WiFi/router).

The admin login for a router is separate from the Wi‑Fi passphrase used by clients to join the network.

If you’re locked out, manufacturers typically instruct a reset procedure that restores default admin credentials.

If you’re locked out, you may need router reset steps described by the manufacturer ().

Devices disconnect or never reconnect

This is almost always caused by the SSID/password change not being applied to the client, or by security mode incompatibility. For example, some older devices can’t join WPA3-only networks.

Wi‑Fi clients that stored the old SSID/passphrase will fail to connect until updated or “forgotten” and re-added.

A security mode mismatch (e.g., WPA3-only vs a WPA2-only device) prevents successful association even if the SSID matches.

Practical fixes:

– On a phone/laptop, remove the saved network for the old SSID, then reconnect to the new SSID.

– For IoT devices, re-run the device’s “connect to WiFi” flow using the updated WiFi password.

Confusing 2.4 GHz vs 5 GHz names

If your router uses separate SSIDs per band, devices might latch onto the “wrong” one or fail when their supported capabilities don’t match. If you changed names inconsistently, the fastest troubleshooting step is to confirm which band each device is joining after the change.

Some devices prefer 2.4 GHz due to range characteristics, while others perform better on 5 GHz due to higher throughput.

When SSIDs differ between bands, each band behaves like a distinct network that clients must be configured for.

Verdict: safest way to update without breaking everything

The safest approach is: update SSID and security settings in the router admin page, save, then reconnect devices one-by-one while verifying internet immediately. This minimizes downtime and makes it easier to pinpoint which device fails and why.

The main downside is temporary loss of WiFi connectivity across the network until clients re-authenticate, plus some older devices may not support WPA3 or certain security modes. If your environment includes critical equipment that can’t be manually reconfigured (for example, inaccessible devices deployed behind physical constraints), consider deferring the change or using a compatibility mode first (WPA2/WPA3 transition) so fewer clients need re-pairing.

If you want the least stressful WiFi credentials update, focus on one change at a time (SSID and security), save in the router admin interface, reconnect immediately, and verify connectivity as soon as each device group comes back online.

Frequently Asked Questions

How do I change my WiFi name (SSID) and password on my router?

Log into your router’s admin page by opening a browser and entering the router IP address (often 192.168.1.1 or 192.168.0.1). Sign in with your admin credentials, then find the Wireless/Wi‑Fi settings to update the SSID (network name) and the WiFi password (WPA/WPA2/WPA3 security key). Save/apply the changes and reconnect your devices using the new WiFi network name and password.

What is the safest way to change my WiFi password without losing internet access?

Before making changes, ensure you know your router admin login details and have a device connected via Ethernet or a stable session. Update the WiFi password first, then apply changes and immediately reconnect your phone/laptop to the new WiFi password. If you also change the WiFi name, reconnect using the updated SSID to avoid confusion during setup.

Why can’t I find the option to change my WiFi name and password?

Some routers hide these settings behind an “Advanced” or “Wireless Settings” menu, or they may be managed by an ISP app instead of a browser interface. If your network is controlled by a mesh system or gateway app, look for settings in the vendor’s mobile app under Wi‑Fi/Network name or Security. Also confirm you are logged in as an admin—limited user accounts may not allow SSID or password changes.

Which WiFi security mode should I choose when changing my password (WPA2 or WPA3)?

For most home networks, choose WPA3 (if available) because it offers stronger security; otherwise, select WPA2‑PSK (AES). Avoid “WEP” or “WPA/WPA-TKIP” if offered, since they are older and less secure. When you change your WiFi password, use a strong passphrase (a long mix of words or characters) to improve protection.

How do I update the WiFi name and password on a mesh or extenders network?

If you use a mesh system, you typically change the WiFi name and WiFi password through the mesh app (e.g., in Network Settings) rather than the router’s web admin page. For multi-router setups, make sure each node uses the same SSID/passphrase if you want seamless roaming, or set separate SSIDs if you prefer distinct networks. After saving changes, reconnect every device to the correct WiFi name and password, including smart TVs, consoles, and IoT devices that may require re-pairing.
