Apple Airport Express and Comcast

Apple Airport Express and Comcast

I have been using a D-Link DGL-4500 for a few years as my home router.  I have tried many different models from Cisco, NetGear, D-Link, Buffalo, Belkin and Asus looking for a better router, but the DGL-4500 has been a very solid performer and has features that I want/need- such as DHCP reservations, specific port forwarding and port translations.  Tonight I gave the Apple Airport Express a try- and so far it looks pretty good.

One issue with the Airport Express is that it does not do MAC address cloning- which is fairly useful for carriers such as Comcast that cache the MAC address and tie it to to the provided Internet IP address.

I have a Motorola Surfboard SB6120 cable modem and I found that it has a standard IP address of 192.168.100.1.  Putting this address into a web browser brings up some interesting information about my cable connection- including a �Reset All Defaults� option that should clear the MAC address that is bound to the CPE (Customer Premise Equipment) info for the modem.  I say �should� as it did not appear to actually reset when I tried it.  Instead I found a way to have the modem recognize a new MAC address.

• Unplug power from the cable modem and the router (Airport Express)
• Disconnect the Ethernet cable between the modem and the router
• Plug in both devices, letting them boot independently and complete their startup (look at the lights on the modem/router to see when it is done).
• After the Cable modem is done, wait another full minute.
• Plug in the Ethernet cable between the cable modem and the router broadband connection

If all works like it did for me, the cable modem should recognize the new device and use its MAC address for the new CPE.  It takes about a minute to reconnect to the internet, but it should complete.  If not, then you will probably need to call Comcast tech support and tell them you have a new router and they can clear the CPE info remotely.

To setup the AirPort Express, you will need an iPod/iPad or a Mac with the AirPort Utility.  This will be detected in network settings on an iOS device, or it is under Applications �> Utilities under MacOS.  If you are using a PC, you will need to download the Windows Airport Utility from Apple before you start trying to configure this new Internet connection.

I have been fairly impressed; the AirPort Extreme allows for separate private & guest networks, has a decent DHCP reservation system and has a pretty intuitive port forwarding setup.  Fore example, I was able to create a forwarding rule that forwards TCP 80, 21, 3550, 4550, 5550, 5511 and 8866 in one statement (these are used for GeoVision remote monitoring). 

Range seems pretty nice on the Apple device; I will try it out for a few days and see if it is really worth the $180 Apple is asking for it� :)

Apples Airport Series A Router Worth Having

Apples Airport Series A Router Worth Having

In my opinion, having one of these routers in your home is pretty much, if not definitely a necessary requirement. They make things oh-so-easy, and in true Apple style, clean, easy to use and wildly efficient.

Part of my job is to provide advice or make recommendations to my clients on new hardware or software to purchase when faced with a problem  that needs resolving, and usually needs resolving fast and permanent. I dont believe in a bandaid fix in my work, as it usually results in repeat work, and generally an unhappy customer.

Today I had a customer who was in dire need of a new internal network for his office. His modem/router/gateway device, whilst performing efficiently for at least the modem component is very dated and aged, and was starting to have DHCP and routing issues, as well as the wireless signal kept dropping out and was weak rendering it basically unusable. However, having had some experience with the AirPort line of products, I recommended he invest $119 in a small, simple and non-obtrusive device into his network, which would solve a lot of the routing issues, as well as enable easy shared printing.

I gotta tell you, it was great. Not only is the range on this little tiny device excellent, but the built in bonjour services as well as the static allocations for the various devices works excellently. I set the router up to be the PPP dialler also, meaning it handles the internet connection, all the modem needs to do now is keep doing what it does best, handle the data link between it and the DSLAM in the telephone exchange. The best part about this entire setup is that I configured the whole thing (except for the static allocations) without having to plug in a cable.

The AirPort family come in three different flavours currently. The baby of the group (the one I set up today) is the express model, which has a gateway ethernet port (to connect your modem to) and one ethernet port. You can either plug one device into this, such as a network printer, or computer that doesnt have a wireless connection. It has one USB port for either attaching a printer or a storage device, and apart from having the inbuilt wireless, it also has a jack to connect speakers to. Whilst the speaker jack is probably not so effective in an office environment, and probably aimed at the home user, it is great to have. Any Apple device can play music wirelessly through AirPlay to the speakers attached to the AirPort.

The bigger brothers of the AirPort express are the "extreme" models. You can either get one with a hard drive built into it for storing data or making easy backups, or you can get one without the internal storage. The extreme models also have a new technology built into them referred to wireless beaming as well as supporting the 802.11ac wireless standard. If youre streaming HD content, or need the extra range on wireless, this would be a better option over the express version. There are two extra ethernet ports (bringing the total to four, including one gateway port), and the speed of these ports on the extreme models is bumped up to 1gigabit up from 100megabit in the express model).
