Last Thursday afternoon, a close friend of mine gave me a call to ask whether a discounted price he had seen for an iPod Touch was a good deal or not. He was pretty keen on getting an iPod Touch even though the iPhone 2.0 is released in a couple of weeks but he seemed pretty set and doesn’t have a need for another cellphone as his work supplies one for his use.
They don’t currently have a wireless network at their house and seeing as the iPod Touch has wi-fi capability we ended up discussing that I was interesting in selling my current Airport Express Wireless G base-station to upgrade my infrastructure to Wireless-N.
The main reason I wanted to upgrade was actually to have an Airport Extreme Base Station which would allow me to share both printers and also a couple of hard-drives over the wireless. The Airport Express only supports one printer and no hard-drives so I have had to switch USB cables around to print to the other printer in the past.
So, knowing that he was keen for that deal, I went out and purchased a new Airport Extreme Base Stations with Wireless-N and Gigabit ethernet. I also picked up a new Wireless-N capable Airport Express so that I could once again stream music to our downstairs speakers.
My next mission was obviously to map out how I wanted to set up the network and the devices. I love setting up network infrastructure, I don’t purport to say I’m any good at it at all but I find it a hell of a lot of fun.
I plan to sprinkle this blog post with diagrams of the old set-up and the new set-up but my laptop is currently at the shop getting its iSight looked at and I’m using a user-account on Aimee’s laptop which doesn’t have anything that I can easily draw diagrams in. For now I’ll add a textual description.
My network consisted of:
- An ADSL Modem/Router for internet connectivity
- A LinkSys VOIP to POTS adapter, for use with our Xnet Fusion VOIP account
- An Apple Mac Mini, connected in the lounge for entertainment purposes
- Two Apple MacBook Pro Laptops
- An Apple Airport Express, currently in use only as a base station since we moved to our new house
Then I added:
- An Apple Airport Extreme Base Station
- A new Apple Airport Express
And I’ve packed up the old Airport Express.
I wanted to add to the network
There are a couple of restrictions this placed on the network. For internal network QoS, the Linksys VOIP Adapter needs to be placed between the router and the network so that voice traffic gets injected right at the router. This also means that our cordless phone and corded phone need to be connected within a few meters of that adapter.
The RAID enclosure isn’t network capable so it needs to be connected with a meter or so of the Airport Extreme Base Station. As do the printers.
Also, the only two locations in the entire house with a phone plug are the kitchen/dining area and the master bedroom.
So I went ahead and picked out a possible solution. It all works pretty well.
I went the whole hog and set up my Wireless-N network on the 5GHz frequency using wide-channels to get maximum possible throughput. We don’t have any 802.11b or g devices in the house (or so I thought) and I doubt anyone in our close proximity has a 5GHz network set up so all was well.
I have the router in the master bedroom and an ethernet cable running from that into our work room. In there is the Base Station, the hard-drives, the printers and the VOIP adapter attached to the cordless phone base.
Downstairs I have the Airport Express and the Mac Mini. As I eluded to above, it turns out that the Mac Mini isn’t Wireless-N capable as I thought it was, it only supports 802.11b and 802.11g so it ended up being connected via gigabit to the new Airport Express as they’re right next to each other anyway. The Express is currently connected to the Base Station using WDS.
I had a fun time setting up the printers. I decided to stretch USB to the limits and see how far away I could keep the printers from the base station. It turns out it is 7 meters keeping to the skirting board to the first printer and another 3 meters to the second where they are placed quite conveniently now. There is a maximum length of 5 meters between devices so I pulled out an old USB Active Extension cable, then plugged in a 2 meters of USB extension, followed by a USB hub and then plugged the first printer in using a short cable and used a 3 meter cable to reach to the other printer.
I thought I had all my numbers worked out but for some reason, the base stations wasn’t recognising either of the printers! I played around a little and found that the base station didn’t like the active extension cable plugged into it, but it didn’t mind having a hub first and then the active extension so I went down that road. Turns out I would have had to add that initial hub anyway to plug in the hard drives next to the base station so all is well.
I wasn’t particularly pleased with the file transfer throughput so I ended up playing around with WDS, wide-channels, different frequencies and even forcing the base station down to wireless-g to see if I could find out what was happening.
I’m just finishing up testing the network performance using the various settings which I’ll post about at a later stage.
