If your Asus router WiFi stopped working whether it was after a power outage or not, then you should pay attention to some important factors. In this post, we’ll review ALL possibilities and teach you how to address each of them efficiently.
To resolve Asus router WiFi issues, you should first focus on the power delivery and wiring in your setup. Next, you would need to perform a restart and check for any interference. Lastly, you can flush your DNS, re-enable the network and carry out a test if nothing has worked.
Some of the recommendations above might seem challenging for some of you, so later in the post, we’ll describe everything in detail.
First, let’s take a look at what might have happened to your router’s WiFi.
If your Asus router WiFi connection is lost after a sudden power outage, there is most likely power issues with your device.
Take a look at the network globe light, if it is lit up then there should be internet reaching your router, if not, let’s check what might have gone wrong:
1. Power Problem
A temporal power malfunction or issue with your Asus router might suppress the WiFi signal.
2. An Issue with the Device
It is possible that the device you’re trying to connect with to the Asus WiFi has connectivity issues.
3. Cable Malfunction
If after the power outage some of your cables have gone faulty, you will be unable to connect with WiFi.
4. Local Area Issue
In case there is at least an hour post the power outage and there is still no WiFi, then you should call your ISP to check whether it’s only you or ALL users in your local area.
5. Hardware Problem
Power surges often impact devices that were currently working during the issue. If any of the hardware components were damaged, the WiFi feature might not be working.
These are the most common issues that might happen to your router after a power outage.
Next, we’ll discuss fix methods and whether your WiFi has stopped working after an outage or not, our solutions should make a difference.
We’ll start excluding possibilities one by one until you’re left with the one and true cause.
It’s recommended to follow the steps in order so you can not only solve but identify and prevent the issue from appearing in the future.
One of the most fragile parts of your setup after an outage would be the power source.
Take a look at the lights of your router, if none of them are lit up, then your router is not currently working.
In cases such as this one, try the following:
- Change the power source.
- Remove ANY power dividers.
- Check if the power adapter is plugged in accordingly.
- Tighten the connection between the power block and the power cable.
To test if your power adapter is working, touch the power block to check if it is heating up. If it is cold and none of your router lights is lit up, then it’s probably a cable’s fault.
Regardless if there was a power outage or not, you could have done something to your router’s environment that would cause interference.
To check and remove for interference, follow these instructions:
- Ensure that there are NO electronics, especially other WiFi devices near your router.
- Ensure no devices such as consoles or cable boxes are next to your router or beneath it.
- Any large metal object that is nearby your router could interfere with the WiFi signal.
Once you’ve removed the interference, check your WiFi connection through several devices to determine the current WiFi state.
If your Asus router WiFi has stopped working and it is still not functional, you can perform a sequence reset with 30 seconds intervals in between.
That will completely discharge your Asus router and hopefully, the issue will be gone.
To perform a 30-30-30 reset, follow these steps:
- Hold the reset button on your Asus router for 30 seconds.
- Unplug the power adapter for 30 seconds.
- Plug the power adapter and hold the reset button for the final 30 seconds.
Once done, your router will reboot, and afterward, you should be able to check your device for WiFi signal.
If you’re losing a WiFi signal on your phone, then you should re-add the corresponding network to see if the WiFi is going to work.
Here is how to do it:
- Go to the network settings on your phone.
- Click on your WiFi connection.
- On the next page, select Forget.
- Once you’ve erased the network, go back to the WiFi tab.
- Locate your network connection and click on it once.
- Enter your password credentials and click on Confirm.
Test the WiFi now and check if there is an internet connection. If not, you’ll be needing a Windows PC for the next solution.
If you’re connecting to your network but there is no internet, you can try to flush your DNS using a Windows OS computer.
You’ll need to hook up that PC either with Ethernet cable or via WiFi, then follow the steps below:
- Go to the Command Prompt (CMD) as administrator.
- Type “ipconfig /flushdns”.
- Once you’ve inserted this, press Enter.
This will clear the DNS cache and hopefully fix the WiFi. In case that made no difference, there could be a conflict with the IP address so let’s find out!
While having a hooked-up PC to your network, you can disable and re-enable the WiFi network in an attempt to solve any IP conflicts. To do so, follow the steps below:
- Open the Control Panel.
- Go to Network Settings.
- Go to Advanced Network Configurations.
- Right-click on YOUR network and choose Disable.
- Wait for a few moments, right-click again and choose Enable.
If an alert message pops out telling you that an IP conflict has been found, your network should be fine.
But if nothing has happened and there is still no internet on your WiFi, then let’s test the entire network in our next solution.
If you didn’t know by now Windows is offering a free network scan to determine any issues and attempt to solve them.
Here is how to run a network scan:
- Right-click on your network icon in the Taskbar.
- Choose Troubleshoot Network Issues.
- An automatic network scan will start.
- Wait for the network scan to complete.
Once ready there could be two options. It will either solve your problem or tell you what’s wrong.
If you receive a message saying, “No internet from the DNS server”, that generally means that there is no internet reaching your router.
In that case, you can disconnect and reconnect the internet cable (black) or call your ISP for instructions.
To fix the WiFi of an Asus router, hard reset the router and check if the wiring is functional. Then, remove any interference, flush the DNS cache, re-add the network and perform sequence reset.
At last, you can carry out a test and as per the results proceed accordingly.

Now when you’re familiar with why Asus router WiFi stopped working our solution should at least help you determine whether the problem is on your side or not.
If nothing had helped then you’ll definitely need to reach out to your ISP to inspect your internet and router.
