Interference from other devices:

One of the most common reasons for disconnections is interference from other devices. This can include other routers, smartphones, laptops, and even microwaves. To resolve this, try moving your Deco M4 to a different location in your home or office and away from other electronic devices.

Outdated firmware:

Another common cause of disconnections is outdated firmware. Make sure to update your Deco M4 to the latest firmware version to ensure that it is running smoothly and efficiently.

Range issues:

If your Deco M4 is too far from your devices, you may experience disconnections. Try moving your Deco M4 closer to your devices or adding additional Deco units to extend your network coverage.

Network congestion:

If you have too many devices connected to your network, it can cause congestion and result in disconnections. Try disconnecting some devices or upgrading your internet plan to handle more devices.

Power issues:

If your Deco M4 is not getting enough power, it may disconnect. Make sure that it is properly plugged in and that the power outlet is working correctly. Also, check for faulty cables.

Hardware issues:

If none of the above solutions work, there may be a hardware issue with your Deco M4 . In this case, you should contact the manufacturer or retailer for support or a replacement.

Modem Compatibility Issues: 

It’s important to note that not all modems are fully compatible with the Deco M4 system. Incompatibility issues between the modem and the Deco system can lead to frequent disconnections and an unstable connection.

To ensure a stable and reliable internet connection, it’s crucial to make sure that your modem and Deco system can work together seamlessly.

How To Fix Connectivity Issues With The Deco M4?

If you’re experiencing connectivity issues with your Deco M4 system, there are several steps you can take to troubleshoot and resolve the problem.

Here are some potential solutions:

Check your internet connection:

The first step is to make sure that your internet connection is working properly. Check if other devices connected to the same network are experiencing issues. If the problem is only with the Deco system, move on to the next step.

Check the Deco M4 system:

Make sure that all the Deco units are properly connected and powered on. Check if the LED indicators on each unit are displaying the correct status. If there are any issues, try resetting the units and reconfiguring the network.

Check for firmware updates:

Make sure that your Deco M4 system is running the latest firmware version. Check for any available updates and install them if necessary.

Adjust the placement of the Deco units:

The placement of the Deco units can affect the performance of the network. Make sure that the units are placed in areas with good signal strength and minimal interference from other devices.

Check for interference:

Other devices in the vicinity, such as microwaves, cordless phones, or other Wi-Fi networks, can interfere with your Deco system. Try to minimize interference by moving the Deco units away from these devices or changing the Wi-Fi channel.

Adjust the advanced settings:

The Deco M4 system has several advanced settings that can be adjusted to improve connectivity. Consider adjusting the channel width, channel selection, and other settings to optimize the network performance.

Adjust DHCP Server’s Lease Time:

If your Deco is operating in Access Point (AP) mode, adjusting the DHCP server’s lease time can help stabilize connections. A longer lease time prevents frequent reassignments of IP addresses, which can disrupt connectivity.

Use Google DNS Servers:

Switching to Google DNS servers instead of your ISP’s DNS can improve network stability. This change can be made in the Deco app under the network settings.

Stable Power Supply:

Check that your Deco units are connected to a stable power source. Power fluctuations can cause the units to reboot, leading to connectivity issues.

Disable Beamforming and Fast Roaming:

In some cases, disabling fast roaming and beamforming in the Deco app can improve connectivity, especially for devices that do not move around.

Check for Modem compatibility issues:

Not all modems are fully compatible with the Deco M4 system. Incompatibility issues can lead to frequent disconnections. Make sure that your modem is compatible with the Deco system and configure the settings accordingly.

Advanced Fixing Tips To solve Connecting issues:

If basic troubleshooting doesn’t work, you may need to consider more advanced solutions.

Factory Reset:

One such solution is performing a factory reset, which can often be a definitive solution to persistent network problems.

This process restores your Deco M4 to its original settings, eliminating any configuration errors that might be causing connectivity issues.

To perform a factory reset:

  • You can use the Deco app or manually press the reset button on the bottom of the Deco unit for about one second.

However, it’s important to remember that this action will erase all your settings and configurations, so it should be used as a last resort.

A factory reset can effectively resolve issues that firmware updates or other adjustments fail to fix. 

Contact TP-Link Support:

If you’re still facing internet connectivity issues even after trying all the troubleshooting steps, seek professional help from TP-Link support.

Provide details about your network setup, the steps you’ve taken, and any specific patterns or symptoms you’ve noticed.

Be persistent and ask for further assistance or escalation if needed.
