Mixed Wireless G/N Networks

I was doing some testing with my wireless routers over the weekend, comparing the range of the Linksys WRT350N and the Netgear WNDR3300. I noticed that my Lifebook S6510, which has an Intel 4965 AGN wireless adapter, would only connect to the Linksys router at a maximum of 130Mb/sec, whereas it connects to the Netgear at a maximum of 270Mb/sec.

After digging around on the Linksys Community Forums, I found a very long thread discussing WRT350N/4965AGN Problems. As best as I can tell, there is some kind of limitation which restricts the Intel 4965 adapter to a maximum of 130 Mb/sec when connected to the WRT350N. Some say the restriction is in the Linksys, when there are mixed N and G devices on the 2.4 GHz network, and others say it is in the Intel, not allowing it over 130Mb/sec at 2.4 GHz.

I'm not sure yet which is correct, but at least one of them has to be, because I absolutely can't get about 130Mb/sec.
