How To Fix Realtek rtl8188ftv USB Wifi Disconnecting Issue on Ubuntu

Ubuntu 5

In this article, we will explore a common issue faced by Ubuntu users, specifically those using the Realtek rtl8188ftv USB Wifi adapter. This adapter has been known to disconnect frequently, causing a lot of inconvenience. However, don’t worry! I am here to guide you through the process of solving this problem. Let’s dive in!

Quick Answer

To fix the Realtek rtl8188ftv USB Wifi disconnecting issue on Ubuntu, you need to install the correct driver, disable power-saving mode, and reload the driver. Follow the steps outlined in the article for a detailed guide.

Identifying the Problem

The first step in resolving any technical issue is identifying the problem. In this case, you might notice that your Wifi connection is unstable, disconnecting frequently or immediately after being connected. This is a common issue with the Realtek rtl8188ftv USB Wifi adapter when used on an Ubuntu system.

Installing the Correct Driver

The first step in resolving this issue is to ensure that you have the correct driver installed for your Wifi adapter. The driver repository for the Realtek rtl8188ftv USB Wifi adapter can be found on GitHub here.

To install the drivers, open your terminal and run the following commands:

git clone
sudo dkms add ./rtl8188fu
sudo dkms build rtl8188fu/1.0
sudo dkms install rtl8188fu/1.0
sudo cp ./rtl8188fu/firmware/rtl8188fufw.bin /lib/firmware/rtlwifi/

Each command serves a specific purpose:

  • git clone is used to clone the driver repository to your local system.
  • sudo dkms add ./rtl8188fu adds the driver to the DKMS tree, which is a framework that helps manage kernel module drivers.
  • sudo dkms build rtl8188fu/1.0 and sudo dkms install rtl8188fu/1.0 are used to build and install the driver.
  • sudo cp ./rtl8188fu/firmware/rtl8188fufw.bin /lib/firmware/rtlwifi/ copies the firmware file to the appropriate directory.

Checking the Driver Installation

After installing the drivers, you should check if the driver is recognized by your system. Run the command modinfo rtl8188fu in your terminal. This command provides information about a specific module; in this case, the rtl8188fu module.

Fixing the Disconnection Issue

To fix the issue of immediate disconnection, you need to disable the power-saving mode for the Wifi adapter. This can be done by running the following command in your terminal:

echo "options rtl8188fu rtw_ips_mode=0" | sudo tee /etc/modprobe.d/rtl8188fu.conf

Here, echo "options rtl8188fu rtw_ips_mode=0" is used to create a new option line for the rtl8188fu module, setting rtw_ips_mode to 0 (which disables power-saving mode). The | sudo tee /etc/modprobe.d/rtl8188fu.conf part of the command writes the output to the rtl8188fu.conf file.

Reloading the Driver

After disabling the power-saving mode, you need to reload the driver. This can be done using the following command:

sudo modprobe -rv rtl8188fu && sudo modprobe -v rtl8188fu

The sudo modprobe -rv rtl8188fu command removes the rtl8188fu module, and the sudo modprobe -v rtl8188fu command inserts it back. This process of removing and inserting the module is known as reloading the driver.

Testing the Solution

Once you have completed the above steps, reboot your system and try to connect to a Wifi network again. If the steps were followed correctly, the issue of immediate disconnection should be resolved.

Can I revert the changes if the fix doesn’t work for me?

Yes, you can revert the changes by removing the driver and deleting the configuration file. To remove the driver, run the command sudo dkms remove rtl8188fu/1.0 --all. To delete the configuration file, run the command sudo rm /etc/modprobe.d/rtl8188fu.conf. After removing the driver and deleting the configuration file, you can reboot your system to restore the previous state.

Are there any alternative solutions to fixing the disconnection issue?
