  3. Question for anyone that knows a lot about lenovo regarding network card option
3 years ago#1
I'm building a thinkpad edge.

Integrated WiFi wireless LAN adapters:

ThinkPad 1x1 b/g/n

ThinkPad b/g/n Wireless BT Combo (1x1 BGN & BT4.0)

Intel Centrino Wireless-N 2230 (2x2 BGN & BT4)

ThinkPad a/b/g/n Wireless BT Combo (2x2 ABGN & BT4.0)

What do each of these actually mean, and what are the better ones to pick? (The 'Help Me Decide" button doesn't help, as it keeps showing me either the powercord or warranty 'help me decide', and I can't get it to show the one for that.

BT = blue tooth
a/b/g/n are different types of wireless tech. N allows for more bandwidth and is pretty much the standard theses days. I cant think of any use for a/b types, and N is backwards compatible with G.

And what about the 1x1 or 2x2 part?

1x1 or 2x2 has to do with the number of radio chains built into the adapter. If you have a 802.11n network, you need 2x2 to take advantage of the increased speed. 802.11n supports up to 300 Mbps and an 1x1 adapter cannot be faster than 150 Mbps.

Oh and just to be clear: I would recommend any adapter that supports 802.11a/b/g/n and has a 2x2 radio setup.

Looks like that Intel centrino would be the right choice for me then, thanks.
