Your router runs its own small operating system called firmware. Like your phone, it needs updates. Many people never update their router, which leaves known security problems open for years.
Why update?
- Security: fixes weaknesses that hackers can use to take over routers.
- Stability: solves random disconnections and freezes.
- Performance: some updates improve Wi-Fi speed and device compatibility.
Before you start
- Connect your computer to the router with a cable if possible.
- Make sure power is stable. Do not update during load shedding unless the router is on a UPS.
- Note your Wi-Fi name, password and any special settings, in case they need to be entered again.
Method 1: Automatic update
Many modern routers and their mobile apps have an Update or Check for updates button. Open the app or the router settings page, find the System or Firmware section and follow the prompts.
Method 2: Manual update
- Log in to the router (usually 192.168.0.1 or 192.168.1.1).
- Find the model number and hardware version on the router’s label.
- Download the matching firmware only from the manufacturer’s official website.
- In the router’s Firmware Upgrade page, choose the file and start the update.
- Wait for the router to restart. This can take a few minutes.
Golden rule
Never switch off the router during an update. An interrupted update can damage the router permanently.
After the update
Check that the internet and Wi-Fi work, then change the admin password if it was reset.
How often?
Check every three to six months, or turn on automatic updates if your router offers them.
