There is a possibility that the connection has failed due to some reason in the error log which could explain why the device you identified previously isn’t functioning properly.

In these cases, you should try to connect your device again to see if it works. This solution is recommended when the error log does not work correctly.

The best thing you can do is reconnect the device to the WiFi network to see if the error occurs again. If it does, then you should try rebooting or resetting it.

How to Find Out If My Device Is Blocked

When it comes to WiFi networks, it is possible for a device to be prevented from accessing or connecting to the WiFi network.

This can easily be achieved by filtering the MAC address (a device’s unique location) of the device.

In order to find out if your device has been denied access, check the password on the WiFi network.

In Network and Sharing Center, click the network’s entry in the left sidebar, and then tap the Connect button to connect to the network.

Make sure you have entered the right network password while opening Network Settings.

  • Block Neighbor’s WiFi Interference

In this case, one of the reasons for delays in your work could be the WiFi of your neighbors.

Having several WiFi services within a close proximity can lead to a non-working connection that is causing disruptions in your work. It is that the different services try to override each other.

There are a few ways to block neighbors’ WiFi interference, such as moving the WiFi router to a new location, adjusting the WiFi router frequency, switching to Ethernet, or jamming WiFi using a blocking signal that is sent across the neighborhood.  

Ways to Manage Devices Connected to Your WiFi

As a means to protect your home network from being constantly invaded by your neighbors and even your children, you can control and manage the different connected devices that are connected to it.

You can use a strong and secure password, such as 16 characters long, to protect the network.

The name of the router should also be changed (SSID – Service Set Identifier), so that random freeloaders will not be able to access your wireless network.

Encrypt your network with WPA or WPA2, and filter devices using their MAC addresses for more security.

  • Enable WLAN MAC Filter

As a wireless security feature, MAC Filtering is a feature that allows users to protect their network rather than setting up a WiFi password but isn’t really safer than setting up a WiFi password.

This is one of the most popular features in the Wireless Tool, but it does not increase the security of your network.

In order to determine whether your MAC address is blocked, test for a blacklist filter. Alter your device’s MAC address temporarily until it links with a different MAC address. In this case, the MAC address is blocked.
