Harden Your Home Network in Under an Hour

Why This Matters

Home networks power our work, banking, and kids’ homework. Defaults prioritize convenience over safety, and criminals know it. The good news: with 45–60 minutes you can remove common attack paths without learning a new career.

1) Update Firmware

Start with your router and any extenders or mesh points. Enable automatic updates if available. Old firmware leaves you exposed to known bugs—low-effort wins for attackers.

2) Use WPA3 (or WPA2‑AES Minimum)

Open the wireless settings and set the security mode to WPA3‑Personal. If older devices fail to connect, use a mixed WPA3/WPA2 mode or create a separate WPA2‑only SSID for them. Avoid TKIP.

3) Segment IoT Devices

Smart TVs, cameras, and bulbs don’t need access to your laptop. Place them on a separate VLAN or guest SSID that blocks access to your main network. Many modern routers expose a simple “guest network isolation” toggle—use it.

4) Disable WPS & UPnP

WPS PIN attacks and UPnP misfires are well‑documented. Turn them off, then manually forward only the ports you absolutely need. Most homes need zero inbound ports exposed to the internet.

5) Admin Hygiene

Change the router admin password, enable MFA if supported, and disable remote management from the WAN. Store recovery codes in a password manager.

6) DNS & Ad‑blocking

Consider using a privacy‑respecting DNS provider, or run Pi‑hole on a small device to block known trackers and malicious domains for the whole house.

7) Backups & Recovery

Export the router config after changes. If something breaks later, you can restore in seconds.

Recommended Gear

For tinkerers, a Raspberry Pi makes a great DNS blocker and home lab node. See Pi kits. A cheap managed switch can add VLANs if your router cannot.

Takeaway

Security isn’t a product; it’s a set of habits. Make the changes above part of your yearly spring cleaning, and your home will be a far harder target.
