Many users set up their home network once and forget about the router until the internet suddenly disappears or the connection starts dropping constantly. At this point, the question arises: is it even necessary to update the router if it seems to be working? The answer lies in the design of your device's software and the hidden processes that occur within it.
Network equipment manufacturers regularly release new firmware versions that fix bugs, patch security holes, and sometimes even improve performance. Ignoring these updates can leave your device vulnerable to hacker attacks or prevent it from interacting properly with newer devices.
In this article we will look at why automatic update It's not always the ideal solution to manually check for a new software version and whether it's worth risking stability for new features. You'll learn in which cases router requires human intervention, and when it is better to leave it alone.
Why do manufacturers release updates for routers?
The main reason for releasing new firmware versions is security. Attack methods become more sophisticated every year, and attackers find new vulnerabilities in encryption protocols or device management web interfaces. Critical vulnerabilities are patched with security patches, without which your router becomes an open door to your home network.
In addition to data protection, developers are optimizing the work network driversThis is especially relevant for users who notice a drop in wireless connection speed when connecting a large number of devices. The updated traffic distribution algorithm allows the router to handle the load more efficiently, reducing ping in games and video buffering.
Compatibility with new equipment is also worth considering. Wi-Fi standards are evolving, and new smartphones, laptops, and smart home devices are emerging. Older software versions may not work correctly with the latest devices, such as those that support Wi-Fi 6 or the WPA3 protocol. Regular updates ensure your router remains current in the changing technological environment.

How to tell if your router needs an update
There are several signs that your router's software is outdated and requires attention. Often, the first sign is unstable network performance: intermittent connection interruptions that occur for no apparent reason on the provider's part.
If you notice that your internet speed is significantly lower than what your plan states, even though the cable is connected directly and there are no issues on the provider's side, it's worth checking your software version. Sometimes older algorithms work with frequency ranges do not allow the device to reveal the full potential of the channel.
Another important indicator is the appearance of unknown devices in the list of connected clients or strange activity in the logs. This may indicate that your router's security has been breached, and an attacker is using your network. In such cases, updating the firmware is a mandatory step, along with changing the administrator password.
⚠️ Attention: If your router no longer recognizes the SIM card (in the case of 4G/5G models) or has lost its settings after a power surge, a simple update may not help—the device's file system may be damaged.
You can check the latest version through the web interface. To do this, enter the IP address of the device (usually 192.168.0.1 or 192.168.1.1) in the browser, enter your login and password, and find the section System Tools or AdministrationThe current version and its release date will be indicated there.
Preparing for the procedure: risks and necessary steps
Before starting the update process, several preparatory steps must be taken. The most important rule: never interrupt the device's power supply while the new firmware is being flashed. This could cause irreversible damage to the firmware, rendering the router "bricked" and requiring a service center.
We recommend resetting your settings to factory defaults or, more sensibly, backing up your current configuration. This will allow you to quickly restore internet access and Wi-Fi settings if you experience problems saving settings after the update. Save the backup file to your computer or external drive.
Make sure you download firmware only from the manufacturer's official website. Using files from third-party sources may contain malicious code or be incompatible with your hardware revision. Always check the device model and hardware version, which is often indicated on a sticker on the bottom of the case.
☑️ Checklist before updating
Step-by-step instructions: how to update your router manually
The update process may vary depending on the brand, but the general steps are the same. First, connect your computer to the router using an Ethernet cable. Using Wi-Fi for updating the firmware is highly discouraged, as the slightest signal fluctuation can interrupt data transmission and damage the device.
Access the control panel via your browser. Find the section responsible for system updates. Modern models often have a "Check for Updates" or "Update Online" button. If this option isn't available, select "Manual Update" and specify the path to the downloaded firmware file.
Once the process starts, the download and installation will begin. The screen may go blank, and the router's lights may flash erratically—this is normal. Leave the device alone for 3 to 10 minutes until it completely reboots and the Ready light comes on.
| Manufacturer | Menu section | The path to renewal | Peculiarities |
|---|---|---|---|
| TP-Link | System Tools | Firmware Upgrade | Requires an exact match of Hardware Version |
| Asus | Administration | Firmware | There is a built-in update search |
| Keenetic | System | Updating components | Modular system, upgradeable components |
| Tenda | Tools | Firmware Upgrade | Often requires reset after update |
What should I do if the Internet is lost after an update?
If the router works after updating but the internet still isn't available, try performing a full reset using the recessed button on the router. Press and hold it for 10-15 seconds while the power is on. Then, reconfigure your connection to your ISP using the details in your contract.
Automatic Updates: Pros, Cons, and Setup
Many modern routers, such as Google Nest Wifi, Asus or Keenetic, support automatic updates. This is convenient for those who don't want to deal with technical details. The system automatically checks the manufacturer's servers and installs new versions in the background.
However, this method has its drawbacks. Automatic updates can occur at the most inopportune moments, such as during an important video call or online game, causing a brief connection interruption. Furthermore, you don't control which version is installed, and sometimes new versions may contain bugs that haven't yet been identified by the community.
You can configure this function in the section Administration or SystemThere's usually an "Auto Update" switch and the option to choose a time to install updates (e.g., overnight). It's recommended to enable this option only if you're confident in the stability of your Widget.
Comparison of methods: online update vs. manual installation
The choice between manual installation and updating online depends on your goals and level of experience. The online method is simpler and faster, but it depends entirely on the router's stable connection to the manufacturer's servers. If the connection is weak or the server is overloaded, the process may stall.
Manual installation via file gives you complete control over the process. You can choose a specific stable version recommended on the forums or roll back to a previous version if the new version isn't working properly. This method is more reliable, but requires more user interaction.
The table below provides a comparison of the two approaches to help you decide which strategy to use for your network.
| Criterion | Online update | Manual installation (file) |
|---|---|---|
| Complexity | Minimum (1 click) | Average (search, download) |
| Risk of failure | Depends on the channel to the server | Minimal (local transfer) |
| Version control | Only the latest available | Any available version |
| Speed | Depends on the internet router | Depends on LAN speed |
⚠️ Attention: Menu interfaces and item names may vary depending on the firmware version and device model. If you can't find the section you need, refer to the official documentation on the manufacturer's website.
Frequently Asked Questions (FAQ)
Are router settings reset after a firmware update?
