In this blog post, we will be discussing a common issue that many people face when their AC WiFi stops working after a sudden power cut. This can be a frustrating and confusing problem to deal with, but don’t worry, we will be providing you with all the information you need to troubleshoot and resolve the issue.
Causes of the issue
The most common cause of AC WiFi not working after a sudden power cut is a disruption in the wifi settings or configuration, and the AC is unable to reconnect to the wifi network. When the power is abruptly cut, the router or modem may not be able to properly reboot and re-establish a connection to the network. This can result in the AC WiFi not working.
Another possibility is that the power cut caused damage to the wifi module or antenna in the AC, and it may need to be repaired or replaced.
More possible causes include firmware bugs, driver issues, or conflicts with other devices on the network.
It’s also possible that the problem could be with your internet service provider or the device you are trying to connect to the network with. In that case, you should check with your internet service provider to see if there are any outages or issues in your area. You can also try connecting to the network with a different device to see if the problem is specific to one device.
Troubleshooting steps
When troubleshooting the issue of AC WiFi not working after a sudden power cut, there are a few basic steps that you can take to try and resolve the problem. These steps include checking if the router or modem is properly plugged in and powered on, resetting the router or modem, and checking for and installing any firmware updates.
- Check if the router or modem is properly plugged in and powered on. Make sure that the power cord is securely plugged into the router or modem and into a working power outlet. Check that the power light on the router or modem is on, indicating that it is receiving power.
- Reset the router or modem. To do this, locate the reset button on the router or modem, and press and hold it for 10-15 seconds. Release the button, and wait for the router or modem to reboot and re-establish a connection to the network.
- Check for and install any firmware updates. Firmware updates can often resolve bugs or issues that may be causing the AC WiFi to not work after a sudden power cut. To check for updates, log into the router or modem’s web interface and check for any available updates. If there are updates available, follow the instructions to download and install them.
It’s important to note that these steps are general troubleshooting steps, and may not always resolve the issue. But these steps are good starting point for resolving the problem. If the problem persists even after trying these steps, you may need to move on to more advanced troubleshooting methods.
Advanced troubleshooting
If the basic troubleshooting steps outlined in the previous section do not resolve the issue of AC WiFi not working after power cut! There are a few more advanced steps that you can take to try and resolve the problem.
These steps include checking for and updating the driver for the wireless adapter, checking for and resolving conflicts with other devices on the network, and checking for and resolving any issues with the router or modem settings.
- Check for and update the driver for the wireless adapter: The driver is the software that controls the wireless adapter and allows it to connect to the network. Sometimes, the driver can become outdated or corrupted, which can cause issues with the AC WiFi. To check for and update the driver, go to the manufacturer’s website and download the latest version.
- Resolve conflicts with other devices on the network: Other devices on the network, such as other routers or modems, can interfere with the operation of the router or modem and cause the AC WiFi to not work properly. To check for and resolve conflicts, log into the router or modem’s web interface and check for any devices that may be causing interference.
- Router or modem settings: Sometimes, issues with the AC WiFi can be caused by incorrect settings on the router or modem. To check for and resolve any issues with the settings, log into the router or modem’s web interface and check for any settings that may be causing issues. You can also try restoring the default settings.
It’s important to note that these advanced troubleshooting steps may require some technical knowledge and may not always resolve the issue.
If the problem persists even after trying these steps, you may need to contact your internet service provider or the manufacturer of the router or modem for further assistance.
What to do if the router/modem is not responding after power cut?

Why AC WiFi Stops Working After Power Cuts and How to Fix It?
There can be several potential causes for problems with WiFi connectivity after a power failure. One possibility is that the router or modem did not properly reboot after the power was restored, and may need to be manually reset.
Another possibility is that the power failure caused damage to the router or modem, and it may need to be replaced.
Additionally, the power failure may have caused interference or disruption to the signal, which may require the repositioning or reconfiguration of the router or other networking equipment.
Protect Your AC WiFi From Power Surges
- Use a surge protector: This is a device that absorbs excess voltage and prevents it from reaching your equipment.
- Unplug your equipment during a storm: If you know a storm is coming, unplugging your equipment can prevent damage from a power surge.
- Use a battery backup: This will provide power to your equipment during a power outage and prevent damage from power surges.
- Use a UPS (Uninterruptible Power Supply): This is a device that provides a backup power source to your equipment in the event of a power outage. It also has built-in surge protection.
- Check the wiring and grounding: Make sure the wiring and grounding in your home is up to code, as poor grounding can increase the risk of power surges.
It’s worth mentioning that, in addition to these preventative measures, it’s also good practice to regularly check the firmware and software of your WiFi devices to ensure they are up-to-date. Which can help to prevent vulnerabilities that could be exploited by power surges.
