OK... I called Netgear tech support to fix some of my problems and now my connection is optimized as best as it's probably gonna get. He had me set the router up at 130 Mhz instead of 270. After I made these changes my Primary (i9300) computer which is running a b/g chip is running smoothly. But more importantly my XPS M1210 is running at about 130Mbs. This may sound gimped but when I tried to copy something from my network file server I was hitting around 4.5 Mbytes/Sec. This is as fast as my wired connection. For some reason I can't get any faster then about 5 Mbyes/Sec transfer speed across my (10/100) network while wired.
Also, I tried an Adhoc network between 2 XPS M1210's with identical Wireless-N chips. My results were the same as you William, I couldn't get any faster than 11mbps. The resulting transfer speed was a pathetic .48 Mbytes/Sec. So.... In other words... Avoid Adhoc like the plague... Unless of course you have absolutely no other choice.
After figuring this all out I am definitely keeping my Wireless-N setup as it is about 1.5-2x faster than my Wireless-G setup. I'm able to do what I wanted to do which was stream dvd quality video from my file server to my wireless-n computer with no stuttering or delays... Although the performance isn't spectacular, it gets the job done and that's all I care for now...
