What are the best router troubleshooting methods for software and firmware issues?

2 Reset to factory defaults

Another router troubleshooting method for software and firmware issues is to reset your router to factory defaults. This means restoring your router to its original state, as it was when you first bought it. This can help you solve problems caused by corrupted or misconfigured settings, or by incompatible software or firmware versions. To reset your router to factory defaults, you can either use a small button on the back or bottom of your router, or use the web interface. Either way, you will need to hold the button or click the option for several seconds until the router restarts. Be aware that resetting your router will erase all your custom settings, such as network name, password, and security options. You will need to reconfigure them after the reset.

3 Reinstall drivers

Sometimes, the software and firmware issues that affect your router are not on the router itself, but on the devices that connect to it. For example, your computer, smartphone, or tablet might have outdated or faulty drivers that prevent them from communicating properly with your router. Drivers are the software components that enable your devices to recognize and use your router and other hardware. To troubleshoot this problem, you can try reinstalling the drivers for your network adapter, which is the device that allows your computer to connect to your router wirelessly or via a cable. You can usually find the drivers on the device manufacturer's website, or use the device manager on your computer to update them automatically.

4 Change channels

Another common cause of router issues is interference from other wireless devices or networks that use the same or nearby frequency channels. Channels are the bands of radio waves that carry the wireless signals between your router and your devices. If there are too many devices or networks using the same channel, they can interfere with each other and cause poor or unstable connection. To troubleshoot this problem, you can try changing the channel on your router to a less crowded one. You can use a free app or software to scan the wireless environment and see which channels are available. Then, you can log into your router's web interface and change the channel setting accordingly. Ideally, you should use channels 1, 6, or 11 for the 2.4 GHz band, and any channel for the 5 GHz band.

5 Flash custom firmware

One of the most advanced and risky router troubleshooting methods for software and firmware issues is to flash custom firmware. Custom firmware is a modified version of the original firmware that adds new features, improves performance, and fixes bugs. However, it is not officially supported by the router manufacturer, and it can void your warranty or even brick your router if done incorrectly. Therefore, you should only flash custom firmware if you are confident in your technical skills and willing to take the risk. To flash custom firmware, you will need to find a compatible and reputable version for your router model, such as DD-WRT, OpenWRT, or Tomato. Then, you will need to download the firmware file and follow the instructions carefully to flash it to your router. You will also need to reconfigure your router settings after the flash.
