Router Suddenly Stopped Working (After Storm, Power Outage; Lights Out)

By SB •  Updated: 05/15/21 •  10 min read

A power disruption is a common reason for a router to suddenly stop working properly. So what do you do to fix this problem to regain all the blinking green lights and a functioning router?

If the router stops connecting to the internet after a storm or power outage, the easiest first step is to plug it into another outlet. If the router doesn’t power on, swap the power adapter for one with similar specs.

After those steps, proceed with the options below to troubleshoot why your router is unresponsive after a power outage or suddenly stopped working.

Router Stopped Working, No Indicator Lights

If no lights are on:

Make sure that the DC plug is compatible with the router, and your location.

If Router Lights Are On

What do the lights mean?

Is the Modem or ISP the Problem? If your router is broadcasting a network (this means your computer or phone can connect to your home network but you’re not able to actually access the internet) then:

Router Firmware Disruption and Corruption. Were you updating your router’s firmware at the time of the power outage? Any new firmware update, or the overheating of the router, may also disrupt internet connectivity.

Reset/Restore Settings. If your router is still not working properly or won’t let you login, factory reset it to its default settings. You will have to re-enter any customized settings later.

Router Working But No Internet

Sometimes after a storm, the router will temporarily lose its stability and a simple reset will fix everything. And sometimes the router is working fine, but the modem has been corrupted by the storm.

Router appears to be working but can’t access the internet — situation: Some of the lights show a connection (usually the network will broadcast but the connection from the modem will be gone)

Consult the Official Support Manuals For Your Router

And if you have a weird problem, such as the only two lights that are lighting up are the power light and the internet light — the 2.4GHz, 5Ghz and every other light are off, consult the troubleshooting manual for your router. Here they are online for Netgear, Linksys (US), Asus, TP-Link. If your router manufacturer isn’t listed, just search duckduckgo.com for “router support [your router make and model]”.

How to Prevent Router Damage in a Storm: Surge Protector, or UPS

Electrical storms and inclement weather can cause high humidity inside your home, which can weaken your indoor WiFi signals. To protect your router from power outages:

Quick and Easy Troubleshooting For Your Router After a Storm or Power Outage

When your router stops connecting to the internet after a storm or power outage, it can feel overwhelming, but troubleshooting can often be straightforward. Follow these steps to restore your connection and prevent future issues.


Step 1: Start Simple – Power and Outlet Issues

  1. Check the Power Outlet
    • Action: Unplug the router from its current outlet and plug it into a different one.
    • Why: Power surges from a storm could damage outlets or trip circuits. Trying a different outlet helps eliminate this as the issue.
  2. Test the Power Adapter
    • Action: Swap out the power adapter with one that has similar voltage and amperage (typically 12V and 1.5A).
    • Why: The adapter may have been damaged, and replacing it is a cheap fix.

Example: You plug the router into a new outlet, but it still won’t power on. Testing with a new adapter gets the router up and running again.


Step 2: Interpreting Router Lights

What do the indicator lights tell you?

Example: If your router has no lights, follow the steps in Step 1. If the lights are amber or blinking, skip ahead to firmware and ISP checks.


Step 3: Is the Modem or ISP the Problem?

Action: Disconnect the router from the modem and plug your laptop directly into the modem.

Modem Troubleshooting:

Example: You plug directly into the modem, but there’s still no internet. After calling your ISP, you discover there’s a temporary outage in your area.


Step 4: Router Firmware Corruption

Firmware corruption is a common issue after power outages, especially if the router was in the middle of an update.

How to Fix Firmware Issues:

  1. Power Cycle: Unplug the router and modem, wait for 5 minutes, then plug them back in.
  2. Log into the Router’s Admin Page: Check if there’s a firmware update available. Install the latest version if necessary.
  3. Reset the Router: If problems persist, reset the router to factory settings (this step is a last resort).

Example: After a power outage, you can’t access the internet. Logging into the admin page, you find a firmware update available and install it, restoring the connection.


Step 5: Resetting to Factory Settings

If your router is still malfunctioning or won’t let you log in, a factory reset may resolve the issue.

How to Factory Reset:

Remember: You’ll need to re-enter your custom network name and passwords afterward.


Step 6: Router Appears to Work But No Internet

Sometimes, the router works fine after a storm, but it can’t connect to the internet.

Symptoms:

Actions:

  1. Check the modem (are its lights off or flashing unusually?).
  2. Reconnect the computer directly to the modem.
  3. Power cycle the modem and call your ISP if needed.

Example: After a storm, your router is working, but the Internet light is amber. Reconnecting directly to the modem shows no internet, so you contact your ISP to resolve the issue.


Step 7: Prevent Router Damage in Future Storms

Protecting your router from power surges or outages in the future will save you headaches.

What You Can Do:

  1. Surge Protector: Plug your router into a surge protector to prevent damage from electrical storms.
  2. UPS (Uninterruptible Power Supply): A UPS offers battery backup and surge protection. This is a smart choice for areas prone to frequent outages or off-grid living.

Example: You’ve installed a UPS that keeps your router running during short power outages, preventing interruptions and equipment damage.
