Your router does more than connect your home to the internet.
It manages the devices using your network and helps keep connections stable.
Like other connected devices, routers use software called firmware. Manufacturers release firmware updates to fix bugs, address security issues, improve performance, and support newer devices.
Checking for these updates is a simple part of router maintenance. However, firmware is only one factor that affects your WiFi experience.
Why Router Firmware Matters for Your Home Network
Firmware controls many of the functions that make your router work.
It helps manage network traffic, connected devices, wireless settings, and other features.
Keeping these elements working together is an important part of a reliable home network setup. Manufacturers release new versions when they find software problems or develop improvements.
Updates can fix bugs, strengthen security, improve stability, and sometimes introduce new features.
Keeping firmware current can therefore help your router work as intended. It can also reduce problems when newer devices connect to your home network.
Problems That Can Come From Outdated Firmware
Out-of-date firmware could be the reason behind a whole range of router issues that later software versions might have solved.
How these issues impact your equipment will depend on both the router model itself and the nature of the firmware update.
Security Weaknesses
Security flaws can sometimes be discovered after a router reaches the market. Manufacturers may release firmware updates to fix these known weaknesses.
Installing available security updates can help reduce exposure to such issues. This matters because your router connects your home network to the internet.

Uneven WiFi Availability
Outdated firmware may contribute to connection drops, glitches, or other performance problems. An update can sometimes correct software-related issues affecting network operation.
However, firmware is not always responsible for poor WiFi. Walls, distance, interference, router placement, and network design can also affect your connection.

Congruence Issues
Newer phones, laptops, smart TVs, cameras, and other devices can use updated networking technologies. Your router may need compatible firmware to support these devices properly.
Keeping the router updated can help maintain compatibility where the manufacturer provides support. Without suitable updates, some devices may experience connection or functionality issues.
Missing Functional Enhancements
Firmware patches might be a means to either refine existing features of a router or, alternatively, to add completely new ones. Of course, these decisions rest with the makers of the products and the type of routers.
A portion of the firmware updates could make your system more stable or expand the number of management options available, or they may fix technical issues that cannot be noticed in a user's normal usage environment.
Modern Routers and Older Routers Need Different Approaches
Not every router handles firmware updates in the same way.
- Newer models often check for available updates automatically.
- They may notify you when one is ready.
- Some can also install updates during selected hours.
- Older routers may require you to find the firmware yourself and upload it through the administration page.
The exact process depends on the manufacturer. Always follow the instructions provided for your specific router model.

Check the Firmware Version Installed
Start by opening your router's administration page or management app. Look for a section named Firmware, Software Update, System Update, or something similar.
Check the version currently installed. The router may also show whether a newer version is available.
Some models automatically check for updates. Others require you to perform this check manually.
Find the Latest Firmware for Your Router
If your router needs a manual update, identify the exact make and model first. Check the hardware version too if the manufacturer lists one.
Download the firmware from the manufacturer's official website. Make sure the file is designed specifically for your router.
Do not assume that firmware for a similar model will work. Using the wrong file can cause the update to fail or create other problems.
Install the Firmware Update
Return to the router's firmware or software update section. For a manual update, select the correct file and upload it as instructed.
Automatic updates may require only a confirmation before installation begins. The router may temporarily disconnect your devices during the process.
Do not switch off, unplug, or restart the router while the update is running. Let the process finish completely.
Restart and Test the Network
The router may restart automatically after installing the new firmware. Your internet connection may be unavailable for a few minutes.
Once the router is back online, check your connected devices. Make sure they can access the internet and connect to WiFi normally.
You can also test areas where you previously noticed connection problems. This helps you see whether the update made any difference.

Remote and Automatic Firmware Updates
Some routers can receive updates without requiring you to download firmware manually. This makes regular maintenance easier for homeowners.
Routers supplied by internet providers may be updated remotely by the provider. Some providers also offer router management through websites or customer apps.
Manufacturers may provide mobile apps with similar controls. Depending on the model, you may be able to check firmware, manage settings, and start updates from your phone.
Availability varies between routers and providers.
Common Mistakes to Avoid During a Firmware Update
A firmware update may take only a few minutes, but preparation is still important. Simple mistakes can interrupt the process or create configuration problems.
-
Use the Correct Firmware
Always download firmware from the manufacturer's official website. Check the exact router model and hardware version before installing it.
-
Keep a Previous Version When Appropriate
For manual updates, keeping a copy of the previous firmware can provide a fallback. This only applies where the manufacturer supports returning to an earlier version.
-
Back Up Your Router Configuration
If your router offers a configuration backup option, use it before updating. An update can occasionally reset customised settings.
A backup may help restore settings such as DHCP, DNS, port forwarding, and other network configurations.
-
Do Not Interrupt the Update
Keep the router powered on during installation. Do not unplug it or press the reset button while the update is running.
-
Choose a Suitable Time
Your internet may be unavailable during the update. Choose a time when your household is less dependent on the connection.
It's better to get professional help. According to the router security survey 2025, approximately 84% of consumers have never manually updated their home router's firmware. This showcases the value of professional help.
When a Firmware Update Is Not Enough to Fix Your WiFi
An updated router cannot solve every WiFi problem.
- Your home may still have weak signals because of walls, floors, distance, interference, or poor router placement.
- The number of connected devices can also affect the network.
- A property with multiple floors or difficult layouts may need a different approach.
If the same rooms continue to have poor coverage after updating the router, the issue may be related to the wider network rather than its firmware.
