Eye-Fi

I got my wife the Eye-Fi 4GB Share Video SD card this year for Christmas.  Yesterday, while we were snowed in, we exchanged a few gifts so she got to open it.  In a nutshell, this SD card has both 4GB of flash storage and a built-in wireless adapter that enables it to wirelessly transmit photos and videos to your computer over your wireless network.

While I thought this would be a great gift, I was a little concerned that it wouldn’t work on the university’s wireless network in our on-campus apartment.  Sure enough, when I tried to set it up yesterday I couldn’t get it to work.  Any time a new device tries to connect to the university’s wireless network the DHCP server assigns it a temporary local IP address and redirects it to a registration web page.  Unfortunately, the Eye-Fi isn’t really a network adapter so you can’t use it to browse the web.  Thus, you can’t visit the registration page in order to register it for use on the network.

After the automatic setup procedure didn’t work I jotted down the card’s MAC address (which is easy to determine using the included software) and emailed the IT people on campus to ask if they could manually add the card’s MAC address to the list of MAC addresses the DHCP server will supply with IP addresses.  They were very helpful and responded that they had added the card’s MAC address as I had asked.

So, now it appears that I’m all set. I spent some time this afternoon getting it set up and I’ve successfully uploaded 5 or 6 pictures and one video using the device. All in all, it’s pretty nice. Hopefully, using this card will simplify the process of getting pictures from the camera to the computer but only time will tell if the device lives up to its promise.

If the card I got my wife works out well, I’ll seriously consider buying the Eye-Fi Pro, which permits you to upload RAW files as well as JPGs and videos.  In addition, it enables you to set up an ad-hoc connection with your PC so you can bypass local wireless networks and upload pictures directly from your card to your computer.  This type of functionality typically costs much more than either the Eye-Fi Pro’s street price of $100 or its MSRP of $150.

    Does my mac adresse change if I upgrade my computer with some other hardware? For example change the graphic card?

      No, the MAC address is a characteristic of the networking hardware in the Eye-Fi card. It won’t change regardless of whether you change hardware on your computer or even use a totally different computer.

      Every networking device has a unique MAC address that is assigned by the manufacturer and stored in the device’s hardware. Hence, it is sometimes also called a hardware address or physical address. Since it is hardware-based, it doesn’t change.

      Each networking device on your computer (wired ethernet card, wireless ethernet card) has a unique MAC address. If you replace, for example, your wireless card, your new wireless card will have a different MAC address than your old one. If you get a new Eye-Fi card, it will have a different MAC address than your original one. However, the MAC address of a given Eye-Fi card is independent of your computer hardware and never changes.

      I hope this helps.
