Finally got around to changing the network adapter in my desktop to a 1.0 Gpbs PCIe card. That's the last step to gettting my home network upgrades finished. The laptops are all running with 802.11n dual band adapters on 5 Mhz band, all the interconnect cables are Cat6, the router is 1.0 Gpbs and the switch is 1.0 Gpbs.
All I need now is 1Gb FIOS to make it into my neighborhood.
