Note: If you cannot fix the problem after you follow these instructions, maybe we can help. Get help from RouterCheck Support.
Understanding the issue
Firmware is the term for the software that runs on your router. Because after all, a router is also a computer. Like any software, firmware can have bugs, and it is occasionally updated. However, updating your router's firmware is a bit different than updating your computer's software. Follow the instructions below to update your router's firmware. They are easy to follow.
Recommendation: Refer to the router's documentation to learn how to fix problems. Go to the vendor's support site where you can download documentation.
How to load new firmware onto your router
Step 1: Log in to your router.
Before you start, you must determine which version of firmware your router is currently running. To do that, you must log in to your router. RouterCheck can give you detailed instructions for logging in to your router.
Step 2: Determine the router's firmware version.
Look through the router's interface and find the firmware version. It should be prominently displayed.
Step 3: Determine the latest available firmware version.
Visit the router vendor's website to investigate downloading newer firmware. Look through the download section for your router model to determine the latest firmware version. Click here for the vendor's support site, where you can download firmware.
Step 4: Download the latest firmware.
If your router is already running the latest firmware, you do not need to do anything else. If not, then download the latest firmware version to your computer. Ensure that you download the exact firmware that your router needs. Important: The firmware must exactly match the router model. In addition, the router models often also have revision numbers that must match.
Step 5: Upload the new firmware to your router.
Return to your router's interface in the browser window that you opened previously. Open to the administrator page and see how to update the router's firmware. Typically, this will be an edit box with a browser button that enables you to select the firmware image that you want to update. Select the firmware that you just downloaded and start the process.
Step 6: Wait for the magic to happen.
If you have done everything correctly up until now, the new firmware should be loading into your router. Do not turn off the power to your router until the process is complete. Perhaps it's time for a break. Take your mind off of routers and sing a little song. We recommend G.T.O. by Ronny & The Daytonas. It's about the right length of time for a router update.
Step 7: The router reboots.
After the router updates, it should reboot itself. After the router reboots, log back into the router and verify that the version number has changed.
Step 8: You are done!
You have successfully updated your router's firmware.
