This may come as a slipped thought, but if you're upgrading your wireless to N (IEEE 802.11n for beyond 100Mbps), the wireless router (or switch if you're just getting a Wireless N Access Point) must have Gigabit (1Gbps) network ports.

Why? Because standard network ports are Megabit (100Mbps), and Wireless N will operate beyond 100Mbps, so this will create a bottleneck when it comes to the physical wired network connection.

Just ensuring your Wireless N router (or Wireless N AP) has Gigabit ports isn't enough, you also need to ensure the other network ports connected to the router or switch has to be Gigabit as well, otherwise again there will be a bottleneck here as Gigabit only works when both ends are Gigabit.

As you can see, Wireless N involves beyond just having a Wireless N network, you also need to ensure the wired network connected to a Wireless N is Gigabit.  This may be overlooked by many as there are Wireless N routers with Megabit ports!
