Home Network Topology, March 2010

I came across a number of questions about home network topology, and decided to diagram mine and share. I am by no means an expert in networking, so if you have a suggestion or two on optimizing this layout, I would be most grateful.

Internet connectivity is provided by Verion FiOS and they installed Actiontec MI424WR in my basement. I have no objections to it as a router (able to control the firewall, no problems with outbound VPN, etc.), but its wireless is limited to 802.11g and didn't cover the entire house. So I looked for a wireless Access Point and settled on TRENDnet TEW-637AP (that was a over a year ago; I am sure there are other worthy products available now). I turned off Actiontech's wireless and TRENDnet took over - it's been exceptionally stable and I am very happy with it. It is set to 802.11n only.

TRENDnet was wired directly into Actiontech. A bit later it dawned on me that my network was limited to 100GB and I bought an unmanaged Gigabit switch (D-Link DGS 2208) and inserted it between my Actiontech and TRENDnet. I then wired the rest of the network to this switch.

The rest should be fairly self-expanatory. Upper left part of the picture shows my office setup. Note that I use Airport Express in wired mode to stream iTunes to my Logitech speakers (love sound quality!). I have a Network Attached Storage (NAS) box - Hammer Storage myshare. It's a fine NAS box, the only thing that bothers me is that the vendor promised a software upgrade with additional features, including iTunes server, and never delivered. On the plus side, it includes a decent print server and turns my super-cheap HP LaserWriter 1020 into a network printer (1020 is not Mac-compatible according to HP, and they are correct - I make it work but it takes a lot of weird contortions).

Did you notice my Newton Message Pad 2100? Very much alive and well!

Lower right is my AV setup - especially proud of my Mac mini - it is running Boxee and works great. Sound system (Bose LifeStyle 35) is not shown here because it is not on the network.

Not to forget my Slingbox - this amazing little gadget lets me watch my own cabe TV on my computer whenever and wherever I want, and I find myself using it frequently. Two thumbs up!

Also not shown are a bunch of assorted computers that are either not hooked up at all or are rarely used.

Lastly, my iPhone 3G is out of luck because I disabled 802.11g. 3G signal is good around here and I am not finding WiFi connectivity for iPhone all that necessary at home.

What's your home network like?
