Changing your WiFi network name and password is easiest when you use your router’s admin page or the router app to update the SSID and security settings in a few minutes. This guide tells you exactly where to click, what to enter, and how to reconnect all your devices afterward. You’ll finish with a new WiFi name and password that work immediately—without guesswork.
Log into your router’s settings, update the WiFi network name (SSID) and the WiFi password, save/apply the changes, then reconnect your phone/laptop to the new network using the updated credentials. If devices won’t join right away, remove (“forget”) the old saved WiFi entry from that device and re-join from the WiFi menu.
This works on most home routers—whether you manage them via a web browser or a router app—because the flow is fundamentally the same: change SSID/password → apply → reconnect devices. The exact button labels differ by brand, but the locations (Wireless/WiFi and Security settings) follow consistent patterns as of 2026.
Who this is for (and when it applies)
If you want a more secure WiFi setup or a clearer network name, changing your WiFi network name (SSID) and password through your router admin page is the right move. It’s also appropriate when you can reconnect devices after the change, because the old saved credentials will no longer work.
For small offices, families, and anyone managing a home network in 2026, this is usually the fastest path to tighten WiFi security—especially when you’re moving away from legacy security modes. From my experience helping users troubleshoot “WiFi works but devices won’t connect” issues, the majority of problems come down to forgetting to update at least one device’s WiFi profile after you change the SSID/password.
Changing your WiFi network name (SSID) and WiFi password through router settings requires that your devices rejoin using the new SSID and password.
Many routers manage WiFi separately for 2.4 GHz and 5 GHz, so your WiFi network name (SSID) or credentials may need updating for the specific band.
Step-by-step: change your WiFi name and password
The most reliable way to change your WiFi network name (SSID) and WiFi password is directly in the router’s Wireless/WiFi and Security settings, then apply and reconnect. Here’s the practical walkthrough that matches most router web interfaces and router apps in 2026.
– Open your router settings using the router’s local address (commonly shown on the router label or in your router’s manual).
– Look for a Wireless / WiFi settings area that lets you edit the SSID (network name) and the security mode (password).
– Save/apply changes, then wait for the router to restart (time varies by model).
Change your WiFi network name (SSID)
Your SSID is the human-readable WiFi network name (for example, “HomeNet-5G” or “OfficeWiFi”). In router settings, you’ll typically see SSID fields for 2.4 GHz and 5 GHz (or you’ll see a combined option like Smart Connect).
– Find the SSID field(s) (often separate for 2.4 GHz and 5 GHz).
– Type the new network name you want, then save/apply.
– If your router uses the same name for both bands (“Smart Connect”), confirm whether you’re changing one SSID or two.
According to IEEE 802.11 specifications, the SSID field is limited to a maximum size of 32 octets, which can affect what network names are accepted by some routers.
If your router uses separate 2.4 GHz and 5 GHz SSIDs, devices will only join to the band whose SSID and WiFi password match your device settings.
Change your WiFi password
Your WiFi password controls how devices authenticate to your WiFi network (SSID). Routers usually offer WPA2 and WPA3 options; these are Wi‑Fi security standards designed to protect the WiFi connection using modern encryption methods.
– In the same Wireless/Security section, locate the password field (it may be under “Security”).
– Use WPA2/WPA3 if available (avoid “open” or legacy insecure options when you can).
– Save/apply, then reconnect devices using the new password.
To make the “security mode” decision easier, here’s a simple comparison you can use while you’re editing the Security setting:
| Security option | Best for | Compatibility note |
|---|---|---|
| WPA3-Personal | Highest security where devices support it | Older devices may not connect if they don’t support WPA3. |
| WPA2-Personal | Broad device compatibility | Often the “safe baseline” when mixed device types are present. |
According to IEEE 802.11i (WPA2-Personal PSK), the passphrase used with WPA2-PSK must fall within a defined character range (commonly 8–63 characters), so router prompts may reject shorter passwords.
WPA2 commonly relies on AES-based CCMP encryption, and AES uses a 128-bit block size (as defined in NIST’s FIPS 197), which is part of why WPA2 is stronger than legacy Wi‑Fi security.
Wi‑Fi PHY Speed Ceilings by IEEE 802.11 Generation (Theoretical Maxima)
| # | Wi‑Fi generation (IEEE 802.11) | Max PHY rate | Typical router band | Speed ceiling |
|---|---|---|---|---|
| 1 | 802.11b | 11 Mbps | 2.4 GHz | ★★☆☆☆ |
| 2 | 802.11a | 54 Mbps | 5 GHz | ★★☆☆☆ |
| 3 | 802.11g | 54 Mbps | 2.4 GHz | ★★☆☆☆ |
| 4 | 802.11n | 600 Mbps | 2.4 / 5 GHz | ★★★☆☆ |
| 5 | 802.11ac | 6.93 Gbps | 5 GHz | ★★★★☆ |
| 6 | 802.11ax (Wi‑Fi 6) | 9.6 Gbps | 2.4 / 5 GHz | ★★★★★ |
| 7 | 802.11be (Wi‑Fi 7) | 46.1 Gbps | 2.4 / 5 / 6 GHz* | ★★★★★ |
Wi‑Fi 7 can operate across additional bands depending on router hardware; secure onboarding still depends on your WiFi network name (SSID) and WiFi password settings.
In practice, changing your WiFi network name (SSID) and WiFi password doesn’t change your Wi‑Fi standard, but it can trigger a compatibility gap if older devices don’t support your chosen WPA2/WPA3 mode.
As a rule, the more advanced your WiFi security mode, the more important it becomes to confirm every device can rejoin using the same SSID and WiFi password.
Update your devices after the change
After you update your WiFi network name (SSID) and WiFi password, devices must reconnect using the new credentials. Many “internet is down” reports after a WiFi change are actually just devices still trying to authenticate with the old password.
– On each phone, laptop, smart TV, and smart home device, select the updated WiFi network name and enter the new password.
– If a device won’t connect, “forget” the old network in that device’s WiFi settings, then rejoin.
– Some devices (like printers or older IoT gear) may require re-setup if they don’t support the router’s selected security mode.
In 2026, I see this most often with smart home devices that were configured once and then “remembered” the earlier SSID/password pair for months. If your router is set to broadcast two separate SSIDs (2.4 GHz vs 5 GHz), the device may only work on the band it supports—so pairing it to the correct SSID (and the correct WiFi password) is essential.
Your phone/laptop WiFi settings store the previous SSID and password, so after you change the router credentials you must select the new SSID and enter the updated WiFi password.
If reconnect attempts fail, removing the old saved WiFi entry (“forget network”) forces the device to retry association with the current SSID and WiFi password.
What can go wrong
Most failures happen when the SSID/password change is applied, but at least one device or one band doesn’t match the new configuration. Another common issue is choosing a security mode that older devices can’t interpret, especially when you update from WPA2 to WPA3-only.
– You change the password but don’t reconnect devices—this makes it look like the internet is “down,” even though WiFi needs re-joining.
– You update the wrong band (2.4 GHz vs 5 GHz), so some devices keep failing while others work.
– You pick an incompatible security setting (for example, forcing a newer mode that older devices can’t handle).
– You lose access because the router admin login was changed or you didn’t have the admin password.
If your goal is better security and fewer disruptions, think in terms of operational rollout: update the SSID/password when you can spend a few minutes reconnecting everything. In networks managed by a shared household or a small team, double-check who might still rely on your current SSID/password—changing it without warning can cause downtime for multiple users.
If devices still try to use the old WiFi password for the previous SSID, they can appear “offline” even though the router itself is healthy.
If your router uses separate SSIDs for 2.4 GHz and 5 GHz, a mismatch between device band selection and the WiFi password you set will cause persistent connection failures.
Verdict / best next step
If you have router admin access, updating your WiFi network name (SSID) and WiFi password through the router’s Wireless/WiFi and Security settings is the fastest and most reliable path to secure your network. The downside is the unavoidable inconvenience: most devices must reconnect, and older printers or IoT devices may require extra steps or a compatible security mode—so consider checking device compatibility before switching to WPA3-only.
If you don’t control router admin access (for example, in a shared or managed network), skip this approach—changing the SSID/password can disrupt other people’s devices immediately. Likewise, if you’re not prepared to reconnect all critical endpoints (laptops for work, security cameras, medical devices), schedule the change for a maintenance window.
Router-based SSID and WiFi password changes are the standard method for securing a home network, but they require a coordinated device reconnection to avoid perceived outages.
When troubleshooting connection issues after changing the WiFi password, verifying the correct SSID (and correct band) is usually faster than rebooting the modem or changing unrelated settings.
Quick checklist (scan/save)
| Task | Where to do it | After you save/apply |
|---|---|---|
| Find router admin page | Router label/manual or router app | You can view Wireless/WiFi settings |
| Change WiFi name (SSID) | Wireless/WiFi settings | Network will show up with the new name |
| Change WiFi password | Security/WPA settings | Router will require the new password |
| Reconnect devices | Phone/laptop/device WiFi menu | Old saved networks may fail until updated |
| Confirm both bands (if shown) | 2.4 GHz / 5 GHz settings | Devices connect to the intended network |
In other words, your SSID/password change is only “complete” when every device is successfully rejoined to the new WiFi network name (SSID) with the new WiFi password.

Frequently Asked Questions
How do I change my WiFi network name (SSID) and password?
Log in to your router’s web interface using a browser, then sign in with your admin credentials. Look for Wireless settings (or Wi‑Fi settings) to update the network name/SSID, then go to the Security/Wireless Security section to change the Wi‑Fi password. Save/apply the changes and reconnect your devices to the new Wi‑Fi name and password.
What steps do I follow to change my WiFi password without breaking my connection?
In the router settings, update the Wi‑Fi password under Wireless Security (commonly WPA2/WPA3). After you save and apply, disconnect and reconnect your devices using the new password—phones, laptops, smart TVs, and IoT devices may need manual re-login. Avoid changing other security settings (like encryption type) unless necessary, since that can force additional device troubleshooting.
Why can’t I change my WiFi name or password even though I’m in the router settings?
This usually happens due to wrong admin login, lack of admin permissions, or the router using settings that are managed by an ISP app instead of a web page. Some routers also hide Wi‑Fi settings if the device is in bridge mode or if a guest network profile is controlling the Wi‑Fi name. Check whether you’re logged in as an administrator and confirm the router mode, or use the manufacturer/ISP app if it manages Wi‑Fi configuration.
Which Wi‑Fi security type is best when changing my WiFi password (WPA2 vs WPA3)?
For most users, WPA3 is the best option when all your devices support it, because it offers stronger protection. If you have older devices that don’t support WPA3, choose WPA2-Personal (or a mixed WPA2/WPA3 mode) to maintain compatibility. When you change your Wi‑Fi password, keep the encryption method consistent to avoid connection issues and reduce the need to reconfigure devices.
Best way to change WiFi network name and password using a mobile app instead of a computer?
Many routers let you manage Wi‑Fi from an iOS/Android app provided by the router brand or your ISP. Connect to your home network, open the app, sign in to the router admin account, and navigate to Wi‑Fi settings for SSID and Security. Update the network name and password, save changes, then reconnect your devices with the new Wi‑Fi credentials to confirm everything works properly.
