Easy to install
Can be faster
Can be better made
Was looking for a 2T2R mini PCI 802.11n for my old Toshiba A60 and this is the only one I can find. There isn't much to describe. Just install the card, let windows install the driver and ready to go. It has a consistent throughput 60Mbps which isn't bad, but not that fast for a 300n which can go up to 100Mbps according to my other notebook. Still, it's quite a jump from wireless G 20Mbps.

I have noticed that on both cards that I have had, the metal covers were crashed a little and distorted. The soldering are tilted everywhere too, including the antenna plugs. But they work fine anyway. Just haven't seen these on any computer products over the years.

Connects at good speed
Drivers (Has not been updated since 2008)
Works Great on Dell Inspiron 8500 laptop.

Opened my laptop, removed the old card, inserted this one, attached the 2 antennas and booted the laptop back up. Installed the manufacturer drivers only without their software and it works with windows Wireless configuration.

Speed connects at 300mbps if you set your N router to 40mhz width. At 20mhz width it connects at 150mbps. Have not seen it fall back at all so not 100% sure if the throughput is consistent, but after price match this card was well worth it.
