PC Wifi often disconnects or goes intermittently: Solutions

Possible solutions to solve the problem of a wifi connection that disconnects continuously, intermittently or that reconnects often

wifi disconnects The problems with Wi-Fi are really annoying, they never end and they always seem to depend on different problems. It may be that the line is absent, it may be the fault of the wireless adapter, the router that no longer works too well or that it has a bad configuration, the computer that may have malware or some system error and who knows what else . Sometimes it may be enough to restart the PC or restart the router to resolve, but other times you are left with a wifi that connects and disconnects continuously, intermittently. We have written many articles on Wi-Fi problems, and this time let's see everything you can do when the wifi disconnects often or continuously and the network goes intermittently, losing the signal. To this end, let's see 10 possible causes and solutions that should cover most of the problems with wifi, in a synthetic way and without difficulty for those less experienced.

What to do if the PC's Wifi disconnects often

There are several reasons why the Internet connection continues to disconnect. The most common causes are poor WiFi signal, overworked WiFi network, problems with the Internet service provider, interference with other WiFi networks or nearby devices, outdated WiFi adapter drivers or outdated firmware of the wireless router. If the WiFi disconnects every few minutes, the first thing to do is to check if the connection of other devices that use the same wifi network work well. If everyone has the same problem, it indicates a problem with the modem or router or Internet service provider. If only one device in the network is disconnecting and reconnecting, probably a problem with that computer or smartphone. The primary solutions are to restart the router, restart the PC, update the computer's wifi drivers and try another router. Obviously also important that the PC is close enough to the router and the signal is good and not at the minimum. In case of need, it may be necessary to amplify the wifi network. Regarding the wifi on PC, the most frequent problems are:

Solutions to restore the wifi connection

Solution 1: Network troubleshooting tool The first thing to do when there are network problems of any kind, after trying to restart the router and restart the PC and if there is no connection problem that depends on the line (so if other devices connect normally), that to use the troubleshooter included with Windows 10. The unattended tool will reset the correct network parameters. To find it, open Settings from the Start menu and then go to the section Update and security. Press on the left column Troubleshooting, scroll down the middle section and press Internet connections to run the automatic correction tool.

Solution 2: Reset the networkA network restore uninstalls and completely removes the network configuration stored by the computer and restores the default values. Once the PC has restarted, the network cards will be reinstalled and their settings will return to normal values. To reset the network in Windows 10, open the Settings from the Start menu, go up Network and internet, then, in the section State, scroll down the right part of the screen and click on Network recovery.

Solution 3: uninstall the network card deviceThe WiFi problem in Windows 8 and Windows 10 can be caused by the damaged network card driver. The solution would be to uninstall the network card device from Device Manager and reinstall it. This can be done automatically. Right-click the Start button on the desktop to find Device Manager. In the list of devices, expand to the section Network cards and then right click on the one used for wifi. Choose uninstall and restart your computer to have the network card reinstalled automatically.

Solution 4: optimizing power optionsIf it happens that the WiFi disconnects after suspension, it depends on the energy saving settings: go to Control Panel> Hardware and Sound> Power Options> Change Combination Settings> Change Advanced Power Saving Settings> Wireless Card Settings where to put maximum performance under energy saving mode. Also, open Device Manager again as seen in point 2, right-click on the wifi network card and go to Properties. Then go to the Energy Saver tab and uncheck the option Allow the computer to turn off this device to save energy and press OK to save the changes.

Solution 5: remove the security softwareIf WiFi is disconnected frequently, it may be due to anti-malware. Many third-party antivirus programs can interfere with Windows and cause various problems. Then try to disable the antivirus and check if it solves the problem. If disabling the antivirus does not solve the problem, try removing it and uninstalling the antivirus with a removal program.

Solution 6: Disable roaming sensitivityIf WiFi is often disconnected, it may be due to the roaming sensitivity function which allows the device to choose the network to connect to based on the signal quality. This, however, can lead to confusion on the system if there are two wifi networks available. To deactivate the roaming function, search the Control Panel in the Start menu and open it. Then open the Network section to go to Cwithin network connections and sharing (in Windows 10, you can go to Settings> Network and internet and then scroll down the status tab to find the network connection center). In the left pane, press Change card settings. Right-click on the wireless connection used, go to properties and then on Configure. Switch to the tab advanced and select Roaming Sensitivity and disable it (in many PCs this option will not be found) .After doing so, the PC will not automatically attempt to connect to other available wireless networks and the problem with WiFi should be completely solved.

Solution 7: disable 802.11n mode802.11n the latest wireless standard that offers better range and transfer speed. However, some older routers may not support this standard. To resolve the problem of frequent disconnections, try disabling 802.11n mode on the wireless card. To do this, follow the procedure of point 5 until you get to the card advanced, where among the options you can find the mode 802.11n which can be disabled. After disabling 802.11n mode, the wireless adapter will be forced to use one of the previous standards and the problem should be solved.

Solution 8: change the channel on the routerIf WiFi is disconnected frequently, it may suffer from signal interference. In another article we saw how to connect to the wireless network of the wifi network with the most powerful signal explaining what it means.In another guide we saw how to change the WiFi channel on the Fastweb modem, which is also good for other routers where, in the configuration panel , you will always find an option to choose the wifi channel to use.Note that to avoid interference, it is always advisable to activate the 5 GHz network which compared to the standard 2.4 GHz wifi band wider and has many free channels.

Solution 9: uninstall Intel Pro Wireless or other management softwareIf there are problems with the wifi, it is better to remove, if any, the management program that is completely superfluous. Then use the Windows utility to uninstall the programs and locate the Intel Wireless management software or any other to remove it.

Solution 10: block your PC from connecting to different networksIf you want to prevent the computer from connecting to other wifi networks, these can be blocked. To do this, you must launch a command on Powershell or at the command prompt. Right-click the Start button on the Windows 10 desktop to open Powershell or command prompt with administrator rights and run this command:netsh wlan add filter permission = block ssid = "Network name" networktype = infrastructureAfter executing this command, the specified WiFi network will be blocked and you can repeat this command for all the other wifi that are visible and not used. After blocking most of the available WiFi networks, the problem should be completely solved. This is a valid solution on fixed PCs, but not on laptops that are used in different places.

Solution 11: use Google DNS or other faster DNSDNS can cause problems with WiFi, in order not to take anything for granted, it is better to use a reliable DNS like the Google DNS explained in another article.

Solution 12: Set the connection as PrivateA wifi network set to Public can have frequent disconnection problems. Then try to solve by reading the guide on how to make the network private at home.

Solution 13: Disable the Connect on consumption functionThe consumption connection serves to save bandwidth in case you have limited gigs for internet connection. When enabled, the connection is severely restricted to prevent the PC from downloading too much data. In case we do not need the connection on consumption and the wifi has problems, try to see if it is active in Settings> Network and Internet, up Manage known networks, press the name of the wifi network used and then turn off the switch.


If we still have not solved anything and the wifi continues to be intermittent or slow, we need to buy a new wifi router to replace the old one that could be obsolete or damaged by now. In other articles we have seen several other solutions on how to fix if the wifi slow, up what slows down Wifi network speed and internet connection. Finally, I refer to the guide at solutions to wifi and router connection problems
