Home Network Security

The practical guide to securing a home network — router hardening, WiFi encryption, firmware updates, IoT device isolation, and firewalls, written from the author's own homelab network.

Part 1

Router Security Setup Checklist for 2026

A real router admin panel, walked through step by step: default credentials, firmware, WPA3, WPS, UPnP, remote access, and VLAN segmentation for IoT — with the reasoning for each change.

Part 2

WPA3 vs WPA2: Which Should You Use?

WPA3 beats WPA2 on paper, but older IoT devices can silently drop off a WPA3-only network. What actually changed, and how to run a safe WPA2/WPA3 transition network.

Part 3

How to Update Your Router's Firmware

Most routers never get a single firmware update after setup day. A real CVE that got exploited because of it, a five-minute walkthrough, and which brands actually keep patching.

Part 4

IoT Security: Isolate Smart Devices via VLAN

Another box arrived — a smart plug, a camera, a voice assistant — and the same thought as last time: this thing now shares a network with the laptop that has your tax documents on it. Guest-network toggles do not fully isolate IoT devices. Real VLAN config, inter-VLAN firewall rules, and a verification test.

Part 5

Home Firewall: Do You Need pfSense/OPNsense?

Your router already has a firewall. A decision framework for whether that is enough or whether pfSense/OPNsense earns its complexity — based on what you are actually running (VLANs, self-hosted services, port forwards), with real cost detail.

Part 6

Best Router for Security in 2026

Every best-router-for-security list disagrees with the next, and the models they crown go stale within a year. Four durable criteria — WPA3, firmware update cadence, VLAN support, OpenWrt/DD-WRT compatibility — for evaluating any router yourself.

Part 7

Home Network Security: The Complete Guide

Most home network security checklists treat every step as equally urgent. This hub ranks six already-tested guides — router setup, firmware, WPA3, IoT/VLAN isolation, firewalls, router selection — by effort vs. impact, with a realistic 30-day plan.
