Wireless Network Keep Connecting and Disconnecting On my Computer

Have you ever faced the issue where your computer keeps connecting and disconnecting from the wireless network (IEEE802.11)? It is like you can see the WiFi available in your area with full strength but while trying to connect, it is disconnecting right after made a connection to the network. This tutorial will help you to fix such WiFi connectivity issues. Here we can analyze the common reasons for such an issue with proper solutions to resolve the issue. Here I assume you can see the WiFi on your PC and having issues to make a successful connection. While following the steps provided in this tutorial, you must ensure that there are no other devices which uses IEEE802 signal with same frequency like Microwave oven etc. If you have any such device which is using a signal with the same frequency, I recommend you to turn off before proceeding to next steps.

Resolve Frequent Wireless Disconnection Issues
  1. Check If you can see SSID

    If you are not seeing IEEE802.11 Networks on your laptop, follow the instructions provided in the link below.

  2. Make sure you have the right wireless key

    If you are entering the wrong key, you cannot connect. So make sure you have the correct key (Wireless network Authentication). It is also important to make sure, no one else has the key except only authorized connection users.

  3. Shift to WZC from other utilities

    If you are using different wireless utilities (eg: Dell utility) to manage your IEEE802.11 connections, you may stop it and start using WZC.

  4. Delete all preferred Networks and Refresh the list

    Clear all saved networks on your PC and refresh the wireless network list. Follow the steps provided in the link below for more details.

  5. Unplug the WiFi Adapter and reconnect it

    If you are using a USB adapter, you may unplug the adapter and reconnect it.

  6. Steps to done on Access Point

    Following steps can be done only if you have access to the Access Point(AP) / Router. If you are doubting where there is no signal from a router or AP, follow the steps below.

    Other troubleshooting steps for frequent WiFi disconnection are:

  7. Changing the Wireless Channel to fix frequent disconnection

    Sometimes if there are some other signals using the same channel, you may face intermittent issues due to interference. So changing channel is a good choice.

  8. Change wireless security to fix frequent WiFi disconnection

    Sometimes your computer may not able to adjust with the security settings on your AP. So disable the IEEE802.11 protection enabled on AP and check for the issue.
    Change Security on your Router -WEP or WPA

  9. Change Wireless Network Name (SSID)

    If still face frequent disconnections occur on devices, you may need to change the name of WiFi network from the router. Following router tutorials will help to do it.

  10. Check MAC filter settings

    Wrong MAC filter settings on Router/Access Point can deny you from accessing IEEE802.11 network. Make sure MAC address of your WLAN NIC is allowed to join the WiFi.

I cannot say this tutorial has everything to resolve the issue. There are still many steps to research and fix the connectivity issue. Some of the left out tips are changing the broadcast type, reduce the beacon interval etc to fix this frequent wireless disconnection issue. However, I believe, most of the WiFi connectivity issues will be resolved by following the steps provided in this guide.
