Power outages are a common occurrence, and you may end up with a PC that won’t turn on. Another annoying problem is your Internet not working after a power outage. When the power goes out, it’s important to ensure that all of your devices are still connected to the Internet.

If you have been experiencing issues with your Wi-Fi not working after a power outage, then you should follow these steps to get things back up and running as soon as possible.

Why does my router not work after a power outage? 

There are several different reasons why a router is not working after a power outage. Here are some of the most common ones:

  • The router has been disconnected – It takes time for devices to reconnect after an interruption in power because they need to be powered up before they can connect to their network again. 
  • Internet wiring has been damaged – If your Internet is not working after a power outage, your home’s wiring may have gotten damaged. It will need repair by a technician before being restored.
  • Electrical fault – The router may have been disconnected from its main electrical outlet. This could happen if the power at the main breaker or fuse box has been cut off or if there is something wrong with the electrical outlet itself.
  • Faulty cables – The Ethernet cable may not be working because it’s damaged and hence not receiving an IP address from your ISP. That’s why the Internet is not working after a power outage. 
  • Modem/router firmware – If you’re experiencing problems with your modem not working after a power outage, it’s likely that there’s a problem with the firmware.
  • Router has lost its configuration settings – Your router won’t connect to the Internet if it has lost its configuration settings. It will not be able to send out an IP address or other information needed. 
  • Outdated routers – If you have an old router that doesn’t support USB or Ethernet ports, it may take some time before the Internet is restored. You can still use wireless if you have an older model, but if you want to connect wired devices, you need to upgrade your router.

How do I fix my Internet after a power out?

A power outage may not be a serious matter so try the following before escalating to the slightly advanced solutions:

  • Check for any abnormal flashing lights on your router.
  • Verify if the cable is attached properly to both ends of the wire, especially at the outlet where you plug into a power source. 
  • Unplug all cables attached to your computer and router, including network cables and USB devices then plug them in one by one.
  • Test each of the router’s ports with an Ethernet cable and see if you can access the Internet from those ports.
  • Try to update your router firmware.
  • Restart your router.
  • Reboot your connecting devices. Sometimes your laptop can not detect Wi-Fi but your phone can.
