13 ways to fix the Chromebook keeps disconnecting from WiFi issue

Before we begin, let’s first determine if the issue is with the WiFi or Chromebook. It’s simple. Try connecting your Chromebook to another network and see if the disconnection issue persists.

If the Chromebook works fine on other networks, the issue is with the router or ISP; if not, you’ll have to go through some troubleshooting on Chromebook settings to fix the problem. Don’t worry; we’ve covered all the possible fixes below.

You can also use the Chrome Connectivity Diagnostics tool by Google to pinpoint the reason for WiFi disconnection issues.

Here are 13 ways you can fix the Chromebook keeps disconnecting from WiFi issue.


Make the WiFi network your preferred one

If the disconnection issue is happening at your home, it’s recommended to make that WiFi network your preferred one. This setting will make sure that Chromebook connects only to the selected WiFi whenever it’s in range.

Follow the steps mentioned below to make a WiFi network the preferred one on Chromebook.

This is especially useful in case you’ve multiple WiFi connections at home, all connected to your Chromebook or if you had recently connected to a neighbour’s network and the device keeps trying to connect back to it even though the network is poor as it’s located further from you.

Step 1: Open Chromebook’s settings using the notification menu from the home screen or the app menu.

Choose the correct router frequency

If your router supports two frequencies — 2.4GHz and 5GHz — ensure you’re connected to the right one.

While the 5GHz frequency delivers significantly better speeds than 2.4GHz, it lacks the range. If you’re setting too far from the router or obstructions between the router and your device, the network can get spotty.

So, if you’re situated away from the router, it’s always recommended to use the 2.4GHz band so that Chromebook doesn’t keep disconnecting from WiFi.


Check the router

You can also check the following things in your router to fix the issue.

  • Router’s age: Old routers can often cause compatibility issues while connecting with Chromebooks as the latter keep on updating the network protocol implementations. So, if your router is old and hasn’t received a firmware update in a while, chances are it’s the one causing issues due to obsolted protocols.
  • Encryption: Make sure the encryption is set to WPA2-PSK with AES or at least WPA/WPA2. Selecting only WPA isn’t secure. Now, disable TKIP, WPS, WMM, and QoS.
  • Interference: Check for interference from Bluetooth. Switch off Bluetooth on Chromebook and try to reconnect. If it does, change the WiFi channel. Alternatively, interference from other WiFi networks could also be causing the issue. Use a WiFi analyser tool to see what’s causing the issue.

Reboot the router and Chromebook

Switch off the router for five minutes to flush its cache and perform a hard restart by pressing and holding the Refresh key and Power button.

A hard restart clears the cache and RAM of the Chromebook.

Then turn on the router first, let it establish a connection. Then turn on the Chromebook and connect to the router.

If this doesn’t fix the Chromebook keeps disconnecting from WiFi issue, follow the guide below.

Firmware update

As mentioned above, routers that implement old network protocols can often cause disconnection errors while connecting to devices with updated and more secure protocols.

To avoid this error, go to your router’s settings via the Chrome browser and update its firmware. If the router still keeps disconnecting after the firmware update, you can follow the guides below, but there’s a chance you’d still have to replace your router sooner or later.


Temporarily disable firewall

A misconfigured firewall can often cause issues with WiFi connections. Disable the Firewall temporarily and see if that helps in resolving the issue. Turn it back on and move to the following guide if it doesn’t.


Change the name servers

You can change the name servers from the defaults provided by your ISP to Google’s name servers (8.8.8.8 or 8.8.4.4) or a custom one.

Follow the steps mentioned below to change the name server.

Step 1: Open Chromebook’s settings using the notification menu from the home screen or the app menu.

If that’s the case, you can try logging in as a guest user or signing in to the device as a new user. This will allow you to experience the WiFi connection without any additional apps. If the WiFi is working fine, it’s probably an app that’s causing the WiFi to disconnect.


Uninstall apps

Uninstall any unwanted or rarely used apps from the device. Alternatively, you can also uninstall every app that you’ve downloaded from the Play Store and re-download them again later.
