Step 3: View Devices Connected

Look for “Connected Devices”, “Attached Devices”, “Device List”, or “DHCP Clients.” See device names and MAC addresses for all on network. How to Stop Unknown Devices Connecting to Wi-Fi?

Top Way: Update Wi-Fi Password

Quickest fix: boots all off. Return to router admin page.

Reconnect yours with new password. Stranger stays out. How to Stop Unknown Devices Connecting to Wi-Fi?

Exact Way: MAC Address Block

Target one device only. On the router, look for “MAC Filtering,” “Access Control,” or “Network Filter.” Copy the intruder’s MAC from Step 1. Paste into “Block” or “Deny” list. Tip: Bad guys can fake MACs. Password change beats this for safety. How to Stop Unknown Devices Connecting to Wi-Fi?

Phase 3: Fortify – Prevent Future Breaks

Remove threats. Block new ones too.

• Set WPA3 or WPA2: In wireless settings, select WPA3 best or WPA2-AES solid. Exclude the ancient WEP or WPA.
• Update Admin Login: Lose admin/password – choose a strong unique one in “Administration” or “System.”
• Turn Off WPS: The button-push connect is weak. Disable in the wireless menu.
• Firmware Update: Fixes holes. Check “Firmware Update” in system. Install any.
• Add Guest Network: Isolate visitors. Keeps them from your main devices.
