Why Firmware Is Different From the Apps You Update Every Day
Most people are comfortable updating apps on their phones or computers — but firmware is a different layer entirely. Firmware is low-level software embedded in a device's hardware that controls how it fundamentally operates. Think of it as the instruction manual baked into the chip itself. When manufacturers discover security flaws, fix bugs, or add compatibility with new standards, they push those changes as firmware updates.
Unlike a smartphone's operating system — where OS updates are increasingly visible and automatic — firmware updates on living room devices often happen silently in the background, or worse, not at all unless you manually trigger them. That invisibility is exactly why many households are running devices that haven't been updated in months or years.
Below is a rundown of the connected devices most commonly sitting in American living rooms — and what happens when their firmware falls behind.
Your Home Router
Your router is the single most security-critical device in your home network, and it's also the one most people never think to update. Router firmware patches address vulnerabilities that could allow attackers to intercept traffic, redirect your browsing, or gain access to devices across your entire network.
Most modern routers from major manufacturers include an automatic update setting buried in the admin panel — typically accessible by typing your router's IP address (often 192.168.1.1 or 192.168.0.1) into a browser. If automatic updates aren't enabled, check manually every few months. If your router is more than five or six years old and the manufacturer no longer issues firmware updates, that's a meaningful security risk worth addressing.
An unpatched router can expose every device on your home network to known vulnerabilities.
Smart TVs
Smart TVs run full operating platforms — similar in complexity to a tablet — and manufacturers regularly issue firmware updates to patch security holes, fix streaming bugs, improve remote control responsiveness, and maintain compatibility with services like streaming apps. Outdated smart TV firmware has been linked to vulnerabilities that could allow unauthorized access to the microphone or camera on models equipped with those features.
Most smart TVs check for updates automatically when connected to Wi-Fi, but the setting can be switched off. Navigate to your TV's settings menu, look for a section labeled Support, About, or System, and confirm automatic updates are enabled. If you're weighing whether a built-in platform or an external stick offers better update support, this comparison of smart TV platforms versus streaming sticks breaks down the differences.
Smart TV firmware keeps streaming apps compatible and patches serious platform-level security flaws.
Streaming Sticks and Streaming Boxes
Devices like streaming sticks and compact media boxes tend to receive firmware and OS updates more frequently than the TVs they plug into. These updates often carry important security patches alongside new features and interface improvements. Because these devices are always connected and process account credentials for multiple streaming services, keeping them current matters from both a privacy and performance standpoint.
Most streaming devices update automatically overnight when in standby mode. You can usually force a check through the device's settings under a System or About menu. The same risks that apply to skipping OS updates on phones apply here — delayed patches leave known exploits open longer than necessary.
Streaming devices handle your account credentials, making timely firmware updates a privacy priority.
Soundbars and AV Receivers
Audio equipment has grown significantly more software-dependent. Modern soundbars and AV receivers often support Wi-Fi, Bluetooth, HDMI eARC, Dolby Atmos decoding, and multi-room audio — all of which rely on firmware to function correctly and remain compatible with other devices in your setup. Manufacturers push firmware updates to fix audio sync issues, add codec support, improve app connectivity, and address bugs that cause dropouts or connectivity failures.
Most soundbars can be updated through a companion app on your smartphone, or sometimes via a USB drive downloaded from the manufacturer's support page. Check the product's app or support website at least twice a year. Ignoring updates on audio hardware rarely causes security emergencies, but it frequently causes frustrating compatibility problems with new TVs or streaming services.
Soundbar firmware fixes compatibility issues with new TVs and streaming formats before they become frustrating.
Game Consoles
Game consoles are essentially full computing platforms that connect to online services, store payment information, and communicate with a wide range of accessories. Console makers release system firmware updates regularly — patching security vulnerabilities, improving network performance, adding system features, and maintaining compatibility with new games and accessories. Skipping these updates often prevents you from accessing online multiplayer or downloading new titles.
Consoles generally prompt users to update before launching games or accessing online services, making them one of the easier device categories to keep current. Still, if your console sits unused for months, it's worth powering it on and allowing any queued updates to complete before your next session. Consoles can also be set to download and install updates automatically during low-use hours.
Game console firmware protects stored payment data and is required to access most online services.
Smart Speakers and Voice Assistants
Smart speakers are always-listening devices that connect directly to cloud services, making their firmware security posture particularly important. Manufacturers update these devices to fix vulnerabilities that could expose voice recordings or allow unauthorized access, as well as to improve wake-word accuracy, add skills, and maintain compatibility with smart home integrations.
The good news: smart speakers almost universally update automatically and silently, without any action required from the user. However, it's worth periodically confirming in the companion app that your device is on the latest software version — especially after a reported security disclosure. If you manage other connected devices through a smart speaker, consider it part of your broader room-by-room connected home strategy.
Smart speakers update silently, but verifying current firmware after security disclosures is still worthwhile.
Building the Habit of Staying Current
Checking firmware across multiple devices can feel tedious, but the payoff is real. A single unpatched device — especially your router — can serve as an entry point that compromises every other gadget on your network. Building strong home network security habits from the start means firmware updates should be on your regular checklist, not an afterthought.
Enable Automatic Updates Wherever Possible
Most living room devices offer an automatic firmware update option in their settings menus. Enabling this feature is the single easiest step you can take to stay protected without ongoing effort. For devices that don't support automatic updates — such as some soundbars or older routers — a quarterly manual check takes just a few minutes and significantly reduces your exposure to known security flaws.
For devices that don't support automatic updates, a practical approach is to set a quarterly calendar reminder to manually check each device's settings menu. It takes less than ten minutes and can meaningfully reduce your exposure to known security vulnerabilities. If a manufacturer has stopped issuing firmware updates for a device entirely, that's a signal worth taking seriously — it may be time to consider a replacement.
