HP Mini Wireless N PCIe Card Atheros AR5BHB92-H AR9280 DV7 Series 300Mpbs 802.11a/b/g/n Dual 2.4/5 GHz 2x2 MIMO

The item has arrived in a very short time with an anti-static packaging. It works on Mac OS X El Capitan. You have to flash your BIOS to remove whitelist in T420 though. As far as I saw, Airdrop and Airport work, the connectivity is the same as my previous card Intel Advanced-N 6205. Great product, great seller.

Sent back. It fit but did not work and no Windows drivers available either. Probably why it didn't work.Also, initially had refunding issues but was resolved to my satisfaction.

works great

Has been a real workhorse in my OpenBSD 5.5 firewall/router. Streaming Netflix through two walls and a bathroom to my son's wireless blu-ray player. Also have an average of four phones connected at once

I'm using it in my T420 Hackintosh, and it works, flawlessly. Make sure you flash your BIOS with the modded whitelist, if you're going to do the same.

Works great!,I get twice the bandwidth,It is a good product, and for the price I paid,cannot ,cannot or passor beat that deal

good wireless for Linux ubuntu 13.04 for use with WiFi at 2.4 Ghz and 5 Ghz in a Acer laptop.
