802.11n Wireless in new MB

[mediaguru]

Has anyone noticed that the "802.11n" Airport adapter in the new MacBook is only listed as "(802.11 a/b/g)" in Network Utility?

I have a "802.11n only (5 GHz)" Airport Extreme network. The new MB successfully connects, but Network Utility reports a link speed of 270 Mbits/s. My older 802.11n-equipped MBP connects at 300 Mbits/s.

Something seems to be wrong here...

270 Mbps is well beyond g speed. Your definitely connected as n.

The 30 Mbps difference is nominal.

Indeed, through it is curious that "N" is not mentioned in Network Utility. I wonder if there is some sort of driver mishap?

This may be to due to the fact that the new Macbook uses a Broadcom wireless chipset rather than Atheros. The Atheros connect at 300 no problem, while I have had issues with the Broadcom in the past...
