Windows 10 can’t connect to this WiFi Network: How to fix it?

What causes this problem?

Wireless settings often state that a mobile device must automatically identify the network’s IP address when connected. Sometimes this doesn’t happen, and the IP address process is delayed indefinitely. You may also see the caption “You can’t get an IP address.”

How can I fix an IP configuration error? There are a few general recommendations:

  • Set a static IP address
  • Change the name of your mobile device
  • Restart DHCP server;
  • Reboot your mobile device and router
  • Rename the network
  • To carry out a complete reset of the router.

Here’s a closer look at what to do first and give a quick guide to getting rid of the bug and connecting to the wireless network.

What Is Wi-Fi Mesh And How To Build It

7 reasons and ways to solve an IP configuration error

1. Rebooting devices

The first thing you recommend is to reboot the router and mobile device. Often it helps. The smartphone reboots quite simply: you need to hold the on/off button until a window with disabling and reboot options appears on the screen. Click on the restart and wait for the device to start again.

You can reboot your router in many ways. This is most easily done by disabling and turning on the power. Usually, on routers, there is a crucial responsibility for food. If it is not – you can pull the cord out of the socket, wait half a minute, then insert it again.

You can also restart through the router’s web interface.

2. Deleting DHCP files on Android

If the router is working correctly and connecting other devices to it is easy – it’s in your phone. It is possible that the DHCP files in the directory of the mobile device were damaged. They will need to be removed. This requires the rights of a superuser, meaning this method is only suitable for a rutted device.

If you have a rue, you can start solving the problem. Detailed instructions:

  1. Download and install the ES Explorer app through Play Store.
  2. We open the program. In the menu on the left, you need to activate “Root” to open previously unavailable and hidden directories in the program window.
  3. Next, go to the data->misc-> DHCP folders. In the final directory, you need to find all the files with an extension .lease and .pid, and then delete them.
  4. Reboot the device and check solved our problem or not

3. Inclusion of DHCP on the router

When activated on the DHCP router, there should be no problem connecting any device to the home network. Before setting up this setting, you need to connect to the router through the computer via a wire (twisted pair). After connecting, we open any convenient browser and prescribe in the IP address address address address address the address of the router, and then authorize (if necessary). Typically, the router’s IP address (or web address) and authorization data are located on the wiFi case of the device on a special sticker with information.

Some router models do not need authorization. Here’s how to include DHCP on today’s most popular router brands.


As soon as we open the settings web menu through the browser, we move on to the menu item (located on the left) called DHCP.

When you click on it on the right, you’ll see settings. In the first line, activate the DHCP server, then save the modified settings.

On the more recent routers TP-Link, the firmware interface is slightly different, and accordingly, the location of some settings, including DHCP.

To turn it on, you need to deploy the Network section, then go to the “DHCP server” subsection, then tick the very first line and save the changes.


On the models of this manufacturer, the DHCP server is also activated in just 2 clicks. You need to find the “Network” item in the left menu, then go to the “LAN” section. In the window on the right, under the headline “DHCP server” in the mode line, choose “Allow.”

After the change, we apply new settings. On newer D-Link devices, the path is almost the same. Only at the beginning, you need to open “Advanced Settings.”


Under the headline “Additional Settings,” the “Local Network” item is clicking on it to the left of the menu. Then choose the “DHCP server” tab on top and turn it on, selecting the desired value in the first line.

Don’t forget to keep the changes.


Here, from the homepage, you need to click on the two computers in the panel at the bottom and then go to the Segments section from above. Choose the first line.

In the window opened, we tick the first item to activate the DHCP server. We apply the changed parameters.

4. Reconnecting to the WiFi network

How to Change WiFi Name of Your Network

When you connect on a mobile device, you can try to reconnect to the WiFi network. Here’s what you can do on your Android phone:

  1. Go to your phone settings. Find Wi-Fi (WLAN).
  2. Click on “Delete the Network” to erase data about it from your phone’s memory. Then reconnect to it (the password will also have to be re-written)
  3. Changing the name of the device (change the name of the smartphone (Wi-Fi ->) One of the rare reasons for the IP configuration error occurs on HTC smartphones.

5. Using the FXR WiFi fix

Google Play Store has a special FXR WiFi fix app designed to fix the bug when it occurs. Once installed, the problem of endless IP address acquisition is solved.

Once installed from the market to the phone, the app needs to run. There’s only a “Fix WiFi Connection” button in the window. Click on it. After that, the IP configuration error should be corrected.

6. Disabling a constant search for networks

An error in connecting to WiFi on your Android phone can also occur due to the constantly turned-on search networks. Detailed instructions on how to turn it off:

7. Purpose of static IP address

Another solution to the problem is to install a static IP address. Here’s what you need to do:

  1. Let’s move on to the phone’s settings.
  2. Open WiFi settings.
  3. Turn on WiFi.
  4. Click on the network that is currently connected and hold to open the connectivity settings.
  5. Then you need to click “Change the Network,” then go to the IP address settings. Go to the menu and click on the “Static” line.
  6. Here you need to set your IP address. Don’t change other settings that are open in this window.
  7. When you set an IP address, you need to consider that it needs to be written based on the gateway. For example, if the router’s address is, you can set the device at, where the last number is any of the range from 0 to 255 (except 1). Or it could be a different range specified in the router settings.
  8. All that’s left is to save the changed options.

Once you’ve installed a static address, you’ll need to disable all running apps and restart Wi-Fi (on and off). You can then reconnect to your home network.
