Why does my computer keep disconnecting from wifi?

This is a known issue and we will help you fix it. The usual culprits for this problem are many. Your IP address has changed (i.e., Windows assigned a new one). NetworkManager (“the network connection manager”) doesn’t deal well with these changes, so attempts to re-join the network it thinks you are on. The DHCP and DNS servers might also be flaky.

If you have a desktop, look at your network configuration. Try switching the devices in use to fix the problem (i.e., disable one and see if that fixes it). If you are using a laptop, make sure the NetworkManager applet is not running (by default, it is located in your system tray — an icon of two computers).

If you are using wpa_supplicant, make sure that your /etc/wpa_supplicant/*.conf files have the correct configuration information. For example, if you change your ssid (the network’s name) or its password, update the config file(s) to reflect these changes. If changing the config files does not fix the problem, try running wpa_supplicant as user root (it may need root permissions to open a device).

For more details on this issue, please refer to NetworkManager’s documentation. This page refers to version 0.7.4 of NetworkManager, but it should work for any later versions too. For more answers to your questions, please refer to the documentation on our wiki.

How to stop my computer from disconnecting from my WiFi?

You should first determine what makes your computer disconnect from WiFi. You can use an applet indicator or a tray menu item to show the signal strength. If it disappears as soon as you move your laptop, it might be a hardware switch button (often on the side). If you have multiple wireless devices, make sure that only one is enabled at a time. If it disconnects when you suspend your laptop, try suspending it without closing the lid (you might need to press a special key first).

If your computer keeps disconnecting from the WiFi, please file a bug report . Please be sure to attach any relevant error logs or system information (look for apport-collect). Be patient (it might take some time to investigate this issue) and don’t forget to fill in the “ProblemType” field.

Conclusion

The problem of a disconnecting computer from the network is often caused by some router or OS configuration. Other causes may be related to your hardware or how you use your OS, but cannot always be resolved easily. Unfortunately, the way things work makes it difficult to provide a simple answer that will apply in all cases.
