Update Your Firmware

Your home router is an at-risk Linux server. If the manufacturer stopped updates, the hardware is tech-trash.

Your Router Is a Computer

Your home Wi-Fi router is a Linux computer with an operating system, a web server for the admin interface, DNS resolver, firewall, and often UPnP — all running on hardware that sits powered on 24/7, facing the internet.

Unlike your laptop, your router doesn't prompt you to install updates. Most people never touch router firmware after initial setup. Some routers run firmware from 2019 on a network they haven't thought about since they plugged it in.

This is a serious attack surface.

What Attackers Do With Routers

• DNS hijacking: Modify your router's DNS settings to redirect your traffic through attacker-controlled DNS resolvers. Your browser shows "amazon.com" but you're talking to a fake server.
• Credential harvesting: Proxy your traffic and log unencrypted credentials
• Botnet recruitment: Routers are prime candidates for DDoS botnets (Mirai and its variants)
• Persistent access: A compromised router survives factory resets on devices behind it
• VPN bypass: An attacker controlling your router can observe which sites you visit even if you use a VPN (they can see the timing and size of traffic)

How to Check and Update Firmware

Step 1: Log into your router admin panel (typically 192.168.1.1 or 192.168.0.1)

Step 2: Find the Firmware or Software Update section (usually under Administration or Advanced)

Step 3: Check the current firmware version and compare to the manufacturer's website

Step 4: If an update is available, install it. Some routers support automatic updates — enable this.

End-of-Life Hardware

If your router's manufacturer has stopped releasing firmware updates, it will never receive patches for newly discovered vulnerabilities. The hardware is functionally insecure — a permanently unpatched Linux server on your network.

Signs your router is EOL:

• Last firmware update was 2+ years ago
• Model isn't listed on the manufacturer's current products page
• Manufacturer says "no longer supported"

What to do: Replace it. Budget routers from reputable manufacturers (TP-Link, Asus, Netgear) start around $50 and come with active update support.

Better Yet: Run Your Own Firmware

Advanced option: OpenWRT is an open-source Linux-based router firmware that you can install on many consumer routers. It's actively maintained, receives security patches rapidly, and gives you full control.

Check if your router is compatible at openwrt.org/toh.

Patch your router. Replace it when it goes EOL. Treat it like the server it is.

Get your site properly hardened.
