I'd reccomend getting a nice 300Mbps one like:

Keep in mind that "300mpbs" is 150mbps per channel/antenna. So you have 150up/150down for your local network - still better than 100mbps ethernet.

It's not, at all.


You will never ever see 150Mbps down from a router to a device I guarantee.

Just read some review of high end routers none of them achieve these sort of speeds.



Those speeds are just theoretical limits of the technology.

Use this. I have a router in the basement and a computer on the 2nd floor in the opposite corner. Near perfect speeds.

Combine it with this for even more.

For reference I'm using a Netgear wnr3300 for a router.

Those speeds require much higher gain, usually around -65 dbm to achieve maximum connection speed. The only way you'll see those speeds is with directional antennas, with direct line-of-site to each other. Upgrade the card to http://www.newegg.com/Product/Produc...82E16833320048, and add a 9 dbi dipole to the router to boost gain.

That is not accurate. This card does 300 down and 150 up. Not only that, a 300 megabit N access point or wifi card will only have around 70 to 80 megabit throughput on the 300 megabit side. There are some wireless devices out there that will do more. Also keep in mind wireless is half duplex, so it will not be as fast as a 100 megabit hard wired connection for downloading. It will be much slower on the upload.

This isn't 100% accurate either. Speed is based on connection rate which goes hand and hand with dBm. Gain does not equal dBm. Antenna gain is measured in dBi which is actually a multiplier. You can achieve a 54 megabit connection rate using 802.11G down to -70 or so dBm. You also do not need directional antennas to reach -65 dBm. You can achieve -40 to -45 dBm with 2.1 dBi omni directional antennas at 8 feet away from the AP with direct line of site, and no interference.
