On sale is this USB WiFi Adapter that features WiFi dual band 2.4Ghz/5Ghz AC1300 with dual antennas and Bluetooth 4.2 connectivity. It's a good option for those who have poor integrated WiFi or looking to add wireless connectivity to a PC that doesn't have WiFi.
Alternatively if you need something really simple with 2.4Ghz Wifi only and a slower speed then this Comfast Adapter is a good option too.
It's using the Realtek RTL8822BU chipset which means it may not be fully compatible with MacOS. These drivers on GitHub should work with this USB Adapter.
AU$ based on current MasterCard rate at time of posting, GST inclusive and stacks with cashback.
Even the wifi adapters and now starting to look like creatures.
