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.

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/& .
