Wireless N - ALL adaptes on network need to be N?

I think I read some place that in order to get the wireless N speeds on one machine, then all networked devices needed to be N. If you have a G on an otherwise all N network then it degrades everything to G speeds.. is this true? I have G level HTPC's and Media Center extenders on my network but I want the Draft N in my laptop... before I drop cash on the N card and router, I'd like to know for sure if I need to upgrade EVERYTHING in the house in order for my laptop to see the improvement.

 

To my knowledge all N routers support any N adapters at full speed and allow any G adapters to operate at their G limits, without interfering with each other. That said, I always look for and check a full online or PDF User Manual from the specific maker of any hardware before buying, and google around for interoperability problems with specific equipment I've already got. Sometimes one brand doesn't seem to work with another - N standard in particular is not yet completely done, as you say.

 

Yep this appears to have been something I heard about but it only applies to B on a G network.. N doesn't exhibit this behavior.
