Turn on WPA3-Personal (or WPA2/WPA3 transitional if older devices need it) in your router’s Wi-Fi security settings so new connections use the strongest handshake your hardware supports. Avoid open, WEP, and WPA-only modes. This how-to is wireless encryption—not changing the router admin password, not Android Private DNS, and not VLAN design for cameras.
1. Before you change Wi-Fi security
- Update router firmware from the vendor’s official channel.
- Inventory old gadgets that may not speak WPA3 (some IoT sticks, printers, older phones).
- Have the admin login ready (change it if still default—see admin guide).
- Plan a short outage: devices will reconnect with the new settings.
Third-party firmware from unknown downloads can brick hardware or add backdoors. Prefer vendor-signed updates when you only need WPA3 toggles.

Encryption choices compared
| Mode | Use when | Avoid when |
|---|---|---|
| WPA3-Personal | Clients are modern | Legacy IoT cannot connect and you need that device online |
| WPA2/WPA3 mixed | Household transition period | You can fully retire WPA2-only gear |
| WPA2-only | Hardware cannot do WPA3 | WPA3 is available and all clients work |
| WEP / Open | Never for home data | Always for primary SSIDs |
WPA3 vs router admin password
WPA3 protects traffic between devices and the access point. The admin password protects who can rewrite those Wi-Fi settings. Do both.
3. Steps: enable WPA3 or strongest available
- Connect to the router admin UI on LAN (typed IP or official app).
- Open Wireless / Wi-Fi settings for the band you use (2.4 GHz and 5/6 GHz may be separate).
- Find Security mode / Authentication.
- Select WPA3-Personal if all important clients support it.
- If something critical fails to join, use WPA2/WPA3-Personal mixed (transitional) rather than dropping to WPA/WEP.
- Set a long, unique Wi-Fi passphrase (different from the admin password). Save/Apply.
- Reboot the router if prompted. Rejoin devices; forget old SSIDs on stubborn clients.
- Disable WPS push-button if your threat model includes nearby tampering and your household can live without it.
- Optional: separate guest SSID with its own passphrase for visitors.
4. After you apply settings
- Confirm phones show WPA3 or the expected security in Wi-Fi details when the OS exposes it.
- Segment risky IoT later with a VLAN or guest network.
- Keep endpoint security on PCs with Norton or Bitdefender (TotalAV, McAfee, Avast on-site)—Wi-Fi encryption is not antivirus.
FAQ
My smart bulb will not connect after WPA3-only. What now?
Use mixed WPA2/WPA3 or move fragile IoT to a dedicated SSID/VLAN still using WPA2 while phones stay on WPA3.
Is WPA3 the same as a VPN?
No. WPA3 is local wireless security. VPN protects paths beyond your LAN.
Does changing Wi-Fi encryption change the admin password?
No. Set admin credentials separately.
Mesh satellite will not adopt—help?
Adopt nodes while on Ethernet if the vendor recommends it; ensure all nodes support the same security mode.
If you still want a paid suite
Avoiding how to turn on WPA3 or the strongest Wi-Fi encryption you have does not require paid antivirus. Careful habits and official support paths are a valid buy-nothing stack. If you want multi-device paid protection later, use only these on-site paid links: TotalAV (paid link), Norton (paid link), Bitdefender (paid link), McAfee (paid link), Avast (paid link).
