What is firmware and why the heck is it important to update?

When was the last time you updated your devices’ firmware? Many people don’t realise that firmware updates are just as important as software updates. From routers to smart home gadgets, keeping your firmware up to date can improve performance, security, and compatibility.  
 
What is firmware? 
Firmware is the low-level software built into your devices that controls how the hardware works. Unlike apps or operating systems, firmware lives directly on the device and is what keeps it running smoothly. Common devices that use firmware include routers and modems, smart home devices like thermostats, lights, locks, and plugs, smart TVs and streaming devices, smartphones, tablets, smartwatches, as well as printers and networked storage devices. 
 
Why is updating important? 
Updating firmware is important for several reasons. First, security. Manufacturers release updates to patch vulnerabilities, and old firmware can leave devices open to hacking or malware. Second, performance improvements. Updates can enhance speed, battery life, and stability, and fix bugs that may cause devices to crash or freeze. Third, compatibility. Firmware updates ensure your devices work with new apps, services, or other devices and avoid issues with new Wi-Fi standards or smart home protocols. Finally, updates can sometimes add new features or enhance existing functionality, giving your devices more value.

A quick checklist - How to update firmware safely

✅ Check your device’s manufacturer portal or app for available updates

✅ Back up your device if possible (especially for routers or storage devices)

✅ Follow the manufacturer’s instructions carefully to avoid damaging the device

✅ Schedule updates during low-usage times to minimize disruption 
 
Why doesn’t this happen automatically? 
Many devices now allow automatic firmware updates. Enabling this feature ensures your devices stay protected and up to date without requiring constant attention. However, some common mistakes should be avoided. Don’t ignore notifications for firmware updates, don’t update devices without checking your power or internet connection, and don’t assume that only “old” devices need updates, all connected devices benefit from regular firmware maintenance.

Firmware updates are critical to keeping your devices secure, fast, and compatible with the latest technology. Treat them as a regular part of your device’s maintenance routine, and you’ll avoid unnecessary headaches and security risks. For added convenience, consider creating a monthly device maintenance checklist, including firmware updates, speed tests, and device resets. This simple habit can keep your home or office network running smoothly and efficiently.
