Does an 'N' Router increase the networking speed across computers on a wired network?

Basically my networked computers are all connected to a 'G' Speed router via ethernet cables. My question is simple; will upgrading to an 'N' or 'N1' speed router speed up transfer speeds between the computers on my network, or are the increased speeds on new 'N' routers relevant to wireless connections only? As an additional question related to this, does it make a difference that my main computer has a 10/100/1000 ethernet port, whereas the other computers only have 10/100 ethernet ports?

Thanks in advance.

N has no bearing on the WIRED side of the network. HOWEVER with that said "N" is newer so the chances are an N router/switch will be a 10/100/1000 baseT network meaning it will support Gigabit connections and thus have faster desktop to desktop (wired) connections.

The N refers to the wireless signal only but again, if its an N router it is usually more modern and containing features such as gigabit ports for the wired ports. (not always true, but look for gigabit support)

I recommend the DLINk DIR 655 Extreme linked below in my sources.
