Hi all, I just got a fancy new dual band 802.11n router (and unfortunately my HP dm1z is 2.4 GHz only...) and I'm wondering if people can help talk me through configuring the 2.4 GHz part.

As I understand it, I will only get half speed connections if I use 20 MHz wide channels. But, using 40 MHz channels is bad manners because it will probably interfere with neighboring 802.11g networks. Since I'm in the middle of Manhattan, there are no free channel spaces (my network is "hello world"):



I am currently apparently the only network set to use 40 MHz, and I've had to manually set it to channel 9 since when I leave it on 1, 11, or Auto (where it picks 6), my laptop only connects at 72 Mbps instead of 150. I chose 9 because site surveys didn't show anything on 9...and I know that there is bleed through of channels into neighboring channels, but that can't be helped.

I'm not really sure what I'm asking here...what do people recommend as configuration choices for 2.4 GHz 802.11n networks?
