For Linux (Ubuntu/Debian) the package is suitable rtl8192cu-dkms:

sudo apt update
sudo apt install rtl8192cu-dkms

What to do if Windows says "Could not find driver software"

Try downloading a driver for a different adapter revision (for example, V2 if you have V3). TP-Link sometimes uses the same chips in different versions. Also, check if your antivirus software (e.g., Avast) is blocking the installation of network device drivers.

3. Setting up a Wi-Fi connection in Windows

After successful installation of drivers:

1. Click on the Wi-Fi icon in the tray (bottom right).
2. Select your network from the list and enter the password.
3. If the network is not listed, check:
   • 🔌 The mode switch on the adapter (should be in the position Client)
   • 📶 Router range (the adapter only supports 2.4 GHz)
   • 🔒 Encryption type (must be WPA2-PSK, WPA3 may not be supported)

If the connection is not established, open Network and Sharing Center → Change adapter settings, find Wireless network connection and check its status. A yellow triangle with an exclamation mark indicates problems with the IP address (try manually entering the DNS, for example 8.8.8.8).

The adapter is in Client mode|The router operates in the 2.4 GHz band|The driver installed without errors|VPN and proxy are disabled|The password was entered correctly-->

4. Optimizing connection speed and stability

By default TL-WN823N It runs on default settings, which don't always provide maximum performance. Here's what you can do to improve it:

Settings in the TP-Link Control Panel

1. Install the utility TP-Link Wireless Configuration Utility (comes with drivers).

2. In the section Advanced change:

• 📡 Wireless Mode → 802.11n (instead of Auto)
• 🔄 Channel Width → 20/40 MHz Auto (will increase speed, but may cause interference in densely populated networks)
• 📶 Transmit Power → High (will increase the range, but will reduce the operating time from a USB hub without power)

Router settings for compatibility

In the router's web interface (192.168.0.1 or 192.168.1.1) check:

• 🔒 Security → WPA2-PSK (AES) (best compatibility)
• 📡 Channel width → 20/40 MHz
• 🔄 Wireless network mode → 802.11n (turn off 802.11b/g to increase speed)

To check your actual speed, use the service SpeedtestNormal values ​​for TL-WN823N under ideal conditions:

If the speed is lower 30 Mbps at a distance of less than 5 meters from the router, try:

• 🔄 Reboot the router and adapter.
• 📡 Change the Wi-Fi channel in the router settings (use 1, 6 or 11 - they intersect the least).
• 🛡️ Disable Windows Firewall during the test.

5. Access Point Mode: How to Share Wi-Fi from a PC

One of the hidden possibilities TL-WN823N — works as an access point. This allows you to share internet from your laptop or PC with other devices (smartphones, tablets). To do this:

1. Turn the physical switch on the adapter to the on position. AP.
2. Connect the adapter to USB.
3. Install the utility TP-Link Wireless Configuration Utility (if not installed).

3. Disable your antivirus or firewall—they may be blocking traffic between adapters.

4. Restart your PC after changing the settings.

6. Typical problems and their solutions

Even after proper setup TL-WN823N may behave erratically. Let's look at the most common symptoms and how to eliminate them.

Problem 1: The adapter disconnects periodically

Possible causes and solutions:

• 🔌 Lack of food — connect the adapter to the USB 2.0 port on the motherboard (not via a hub).
• 🔄 Driver conflict - remove all network drivers via device Manager, then install the official package again.
• 📡 Interference from other devices - switch the router to the channel 1 or 11, if you use 40 MHz.

Problem 2: Low speed or frequent interruptions

Check:

• 📶 Signal level - if it is lower 2-3 divisions, move the adapter closer to the router or use a USB extender.
• 🔒 Encryption type — WPA3 or WEP may not be supported. Switch to WPA2-PSK (AES).
• 🖥️ Load on PC - High CPU or memory usage may cause latency in the network stack.

Problem 3: Windows does not detect the adapter after updating

This is a typical situation after major Windows updates (for example, upgrading from 10 to 11). Solution:

1. Open device Manager.
2. Find TL-WN823N in the section Network adapters (may appear as Unknown Device).
3. Right click → Properties → Details → Hardware ID.
4. Copy the first line from the list (starts with USB\VID_).
5. Search Google for the driver using this ID or visit the forum TP-Link.

7. Alternative software for adapter management

Suitable for experienced users Linux-utility iwconfig, which allows you to manually configure adapter settings via the terminal. An example command for scanning networks:

sudo iwlist wlan0 scanning | grep ESSID

8. Modifying the antenna to enhance the signal

Standard antenna TL-WN823N has a gain 2 dBi, which is enough for a small apartment. However, in weak signal conditions (for example, if the router is in another room through several walls), reception can be improved:

Method 1: Replacing the antenna

The adapter has a connector RP-SMA, which allows you to connect an external antenna. Optimal options:

• 📡 Antenna 5 dBi - will increase the range by 20–30%.
• 🏠 Directional antenna 9 dBi — suitable for point amplification of a signal in one direction.

Method 2: Homemade reflector

If you don’t want to buy an antenna, you can make one parabolic reflector from scrap materials:

1. Take a can of chips (Pringles) or a plastic bottle.
2. Cut out the bottom and a hole for the antenna.
3. Line the inside with foil.
4. Secure the structure so that the adapter antenna is in focus.

Such a reflector can increase the signal level by 10–15 dB in a given direction.
