TP-Link TL-WN823N 300Mbps Mini Wireless N USB Adapter
PRODUCT DESCRIPTION
TP-Link 300Mbps Mini Wireless N USB Adapter (TL-WN823N) - 3 Years Local Warranty
The TL-WN823N is a 39 x 18.35 x 7.87 mm nano-format USB adapter that adds 300 Mbps 2.4 GHz Wi-Fi to a laptop or desktop and can be left permanently in the port. Beyond joining a network as a client, it also publishes a Soft AP mode, letting the host machine share its connection as a small Wi-Fi hotspot.
Small Enough to Leave In
The defining feature of this model is its size. At under 40 mm long it protrudes barely past the edge of a laptop, so it can stay in the port when the machine goes into a bag rather than being unplugged and lost. TP-Link rates it at up to 300 Mbps on 11n, 54 Mbps on 11g and 11 Mbps on 11b across 2.400~2.4835 GHz, with an internal antenna.
Soft AP Mode Turns the Host Into a Hotspot
TP-Link publishes two wireless modes for this adapter: Soft AP Mode and Client Mode (Ad-hoc / Infrastructure). Soft AP is the interesting one. With the host machine connected to the internet — over Ethernet, for instance — the adapter can publish its own Wi-Fi network for phones and tablets nearby. In a meeting room, a workshop or a site office with one wired point and no access point, that is a usable stopgap.
WPS Button and WPA2 Security
A Wi-Fi Protected Setup button on the adapter joins a WPS-capable router with a single press. Published wireless security covers 64/128-bit WEP, WPA-PSK/WPA2-PSK and WPA/WPA2, so the connection can carry the same protection as the rest of the network rather than falling back to something weaker.
Check the Operating System Before You Order
TP-Link's published system requirements for this model are Windows 8.1/8/7/XP (32/64-bit), Mac OS X 10.7 to 10.10, and Linux. Windows 10 and Windows 11 are not on that list, and neither are current macOS releases. Driver availability for newer operating systems changes over time — check TP-Link's download page for your hardware version, linked below, or ask us before ordering for a modern machine.
What TP-Link Publishes, and What It Does Not
Certification is published as CE, FCC, IC and RoHS. The adapter is rated for 0°C to 40°C in operation, -40°C to 70°C in storage, at 10% to 90% non-condensing humidity. TP-Link publishes no antenna gain, no net weight, no LED row and no transmission-power figure for this model, so none of those is claimed here.
Ideal For
Laptops that need a spare or replacement wireless adapter, desktops in Singapore homes and small offices without built-in Wi-Fi, and anyone who needs an adapter small enough to live permanently in a USB port. Supplied by SourceIT with local Singapore warranty and a GST invoice.
