A desktop with no WiFi is a quick fix in South Africa: plug in a USB WiFi adapter and the PC joins your home network. The hard part is picking one that matches your router and your desk. The standard, the antenna and the Bluetooth you need all change the price, and a cheap adapter on a desk two walls from the router will disappoint.
Quick Answer
Buy the TP-LINK Archer AX1800 Wireless USB Adapter at R469 if your router is WiFi 6, since it reaches up to 1201Mbps on the 5GHz band. If your router is older, the Cudy AC1300 High Gain WiFi USB3.0 Adapter at R229 is the budget dual-band pick. In a small Johannesburg flat where the router sits two walls away, choose one with a high-gain antenna.
📶 Match the adapter to your router first
The adapter only moves data as fast as the standard you both support. A WiFi 6 adapter on an older router still connects, but it runs at the older router's speed. Check your router's label or app for WiFi 5 or WiFi 6 before you spend anything.
For a WiFi 5 router, the TP-LINK ARCHER T4U Wireless Dual Band USB Adapter at R449 gives 867Mbps on the 5GHz band and 400Mbps on 2.4GHz. For a WiFi 6 router, the Archer AX1800 at R469 is the better buy, with up to 1201Mbps on 5GHz and OFDMA support that helps when several devices share the network. Paying the extra money only makes sense if the router really is WiFi 6.
🔌 USB 3.0, antennas and the desk
Plug the adapter into a USB 3.0 port, usually a blue one on the back of the tower. A USB 2.0 port works, but it holds the adapter back, and a USB 3.0 socket costs nothing extra.
Antennas decide how well the signal reaches the desk. The Cudy AC1300 High Gain WiFi USB3.0 Adapter at R229 carries a high-gain antenna, which helps when the router sits in another room. In a small flat where the router is two walls away, a better antenna and a sensible position can mean the difference between a steady video call and constant buffering. As general advice, keep the antenna away from the metal case where you can.
📡 Bluetooth, drivers and Mac or Linux
If you also want Bluetooth for a keyboard, headset or speaker, look for it on the adapter itself. The ORICO USB Bluetooth-Compatible Dongle at R199 runs Bluetooth 5.3 and EDR, with a transmission distance of about 5m, so it suits a desk-side headset rather than a speaker across the room.
Install the driver before you plug the adapter in, using the version that matches your Windows build. The Cudy AC1300 supports Windows, Mac and Linux, so check the driver for your operating system version before you connect it.

Frequently Asked Questions
Does a WiFi 6 USB adapter need a WiFi 6 router?
No, it still connects to older routers, but at their slower speed. The TP-LINK Archer AX1800 Wireless USB Adapter at R469 tops out at 1201Mbps on 5GHz only when the router supports WiFi 6 as well.
Is an antenna worth paying for on a USB WiFi adapter?
Yes, if the router sits in another room. A high-gain antenna can help the signal at the desk, so position it away from the metal tower where you can.
Which USB port should the adapter go into?
Use a USB 3.0 port, usually a blue one, since the Cudy AC1300 at R229 and the TP-LINK ARCHER T4U at R449 both run over USB 3.0 for their full speed.
Do I get Bluetooth with a WiFi adapter?
Only on some models. The ORICO USB Bluetooth-Compatible Dongle at R199 adds Bluetooth 5.3 and EDR, so check the listing for Bluetooth before you assume it is included.
Does the Cudy AC1300 work on Mac and Linux too?
Yes, it supports Windows, Mac and Linux. Check the driver for your operating system version before you plug the adapter in.
