## Description

What This Product DoesWireless N USB Adapter TL-WN821N allows you to connect a desktop or notebook computer to a wireless network and access high-speed Internet connection. Comply with IEEE 802.11n, they provide wireless speed up to 300Mbps, which is beneficial for the online gaming or even HD video streaming. Wireless N - Speed & RangeWith MIMO (multiple input, multiple output antennas) technology, it shows more excellent abilities of mitigating data loss over long distances and through obstacles in a small office or a large apartment, even in a steel-and-concrete building. Above all, you could easily pick up the wireless network during long-distance connection where legacy 11g products may not! WPA / WPA2 Encryptions - Advanced SecurityAs for the security of WI-FI connection, WEP encryption has been no longer the strongest and safest guards for outside intrusions. TL-WN821N provides WPA/WPA2 encryptions that are created by the WI-FI Alliance industry group, promoting interpretabilities and security for WLAN, which could effectively and efficiently protect the wireless network. One Button Security SetupWI-FI Protected Setup™ (WPS) allows users to almost instantly setup their security simply by pressing the "WPS" button automatically establishing a WPA2 secure connection, which is more security compared with WEP encryptions. Not only is this faster than normal secure setups but more convenient in that you don't need to remember a password! Bundled CD for Easy OperationTL-WN821N comes with a CD with utility that helps you complete the software installation and wireless network settings, including security configurations and wireless connection, which is convenient for users, even for novice users.

## Questions & Answers

**Q: What is the coverage range?**
A: As with all of these types of devices (transmitters and receivers) it depends on several factors that can affect the radio waves.  I was able to use it from the second floor of my home through a wall and a floor from the router, and from outside my house on my porch.  It depends on the strength of the router/modem signal that is transmitting to your computer and what is between your computer and the router/modem. Sheetrock walls are easier to go through than older plaster and lathe, for example. In a concrete and steel building or basement, it may only work in the room. Be leary of any published ranges, as these would be under completely ideal (no walls, completely clear) and unrealistic circumstances. I hope this helps!

**Q: Is this compatible with Macbook Pro?**
A: Hi! I searched the website of TP-Link and it says that is compatible with windows XP/Vista/& . The link is :http://www.tp-link.com/en/products/details/?model=TL-WN821N#down. Also I did not buy this product for my windows desktop ,my model was TP-LINK TL-WN822N. And it only supports Windows too. I tested my model . It is not detected by Mac OS.

**Q: What is hardware version of Device? Is it  version V4 ?**
A: Yes.  Ana

**Q: Does this adapter support Windows 10 Pro?**
A: I only see Win 7 / 8 drivers at their download page: http://www.tp-link.us/download/TL-WN821N.html#Driver

### ⭐⭐ Review
*by M***W on 30 October 2024*

Was disappointed with this product as it was bought as a replacement for an older model from the same line and manufacturer which I thought was malfunctioning. Had the same issues with extremely slow wireless. Was annoying to install as didn't have a plug in and play driver and requires a driver from a mini CD that comes with it (who has cd drive in this day and age?). The alternative was to download the driver from the internet.... which one uses the device to connect to. Bought another brand and internet now works fine.
