Wireless by Senao



Ok, so apple refers to their wireless technology as "airport".  Under that same logic, shouldn't they call the built-in 10/100 network port a "bus station"?  Ok, enough jokes.  When I bought the ibook, I researched a bit and noticed that it had what looked like a pcmcia slot under the keyboard.  By pulling up the keyboard, I could see this card.

What's wrong with airport?

The die-hard mac people are already mad at me for switching to Ubuntu and liking it.  So if you're still reading this and asking me why I didn't just get an airport card and be done with this problem, then that means you're a bias free individual that can understand my reasoning.  Much like this ibook, the airport card in question is no longer being manufactured by apple.  So, what happens when you take a reatively expensive wifi card and cease production of said card?  Yeah, you guessed it.  The card gets freakin expensive!  Even when I turned back to my best friend - eBay, the 802.11b card still runs from about $75 bucks on up.  And I mean way up.  So after exhausting all of my eBaying techniques (broken cards, misspelled auctions, etc...) I finally gave up on an apple airport card.  I cannot justify paying $75+ for an exceptionally average 802.11b card.

Oh man, what options do you have?

Yeah, that was my first thought.  Basically, what you have to do is find a wifi card that doesn't have a built in antenna sticking off the end of it.  Anyone who has put a wifi card into a laptop knows what I'm talking about.  It's about an inch of ugly bulk sticking out of your nice clean laptop that looks goofy, and is even harder to keep from breaking off.  In addition to the smaller size, the ibook has a built in antenna.  So you need a card that is not only shorter than the average wifi card, but you also need one that has a socket to plug in the antenna.  If I knew the technical name for this port, I wouldn't have had to modify the antenna to plug into the card that I bought.  But we'll get to that in a second. Here's a few pictures of the available space you're working with:

So, the options as I have discovered are the following:


    1.   There's a guy that has crammed a cheap orinoco gold card into the airport slot.  He stripped all of the plastic
          covering off of the card, removed the metal housing that covers up the RAM slot of the ibook, and (gulp) tweaks
          the card into the pcmcia slot.  This is a good option if you're still running Mac OSX because the orinoco has the
          same chip set as the airport card.

side note:  Mac people will swear that this is no pcmcia slot.  They'll say something about it having extra pins that do different stuff yadda yadda yadda....Look, if you can put a pcmcia slotted card in it and have it work normally, I'll go out on a limb and say it's a pcmcia slot.

    2.   Other wifi cards that adhere to the shorter size are:
          Cisco 350 aironet cards.  - They have 3 different types, one for pci, two for pcmcia.  Out of those, only 1 has an
                antenna.
          Zcomax
 
Both of these cards are high dollar cards that fit in a smaller package, and like the airport, I couldn't track these down for a lower price.

So, I settled on the Senao wifi card.  Here's the why's:

I ebayed the Senao card for about 30 bucks.  They aren't all that cheap, but they are abundant enough that I found an auction for the cards that had no label on them (who knows why they did that) and they were also in a large dutch auction.  Secondly, the Senao is in the same tier as the Cisco and the Zcomax cards in that they are long range wireless cards.  So here's the punch line:  This card pumps out 200 mW of power!  Your average 2.4 GHz wifi card outputs around 30 mW of power.  Now i'm no electrical engineer...but I did get all the way through 3rd grade and know that the Senao outputs roughly 7 times the amount of power of your average card.  Lastly, the card fits in the slot!  I wasn't sure at the time I bought it, but it was a hunch I was willing to gamble 30 of my hard earned dollars on.  Here's a shot:

While it does have an external antenna, it is much shorter than the other wifi cards.  Also, you can see one of the two external antenna jacks that come on the card.  This will be good later for the apple built in antenna.  Right around these jacks are a couple of raised plastic bumps.  Keep these in mind because I had to get rid of them to make the card fit.

Doing the dirty work

First thing I did when the card came in was to put it into the laptop slot and see if it was going to fit:  Card in Laptop
This picture is actually after I did a little work on the card (sorry, I forgot to take pics until after the fact).  It just fits in the card slot perfectly, as if it was made to fit there.  However, what wasn't made to fit perfectly was the antenna connectors.  They were almost the right size to fit together.  It was ugly and more of a hack job than anything, but I got the trusty dremel tool out and removed the outer sleeve from the laptop's antenna connector.  Once this was done, the inner probe would slide into the female connector on the card, and because of the tight quarters, it stays in.  So, enough with the explanation, here's some pics.  The first one shows the quick dremel job I did on the wireless card to remove the little knobbies so that it would fit nicely in the laptop.  It's fuzzy, but it's the best I could do.

Once I got the card trimmed down, I put it back into the slot, plugged in the trimmed up antenna connector and turned on the ibook.  One of the great things about the Senao card is that the drivers are built into the linux 2.6 kernel...so it was truly plug and play.  This is great for linux since almost nothing is plug and play with it.  But sure enough, I fired up the laptop and opened my handy wireless network connection program, and it connected to my wireless network with no problems.  That's it.  I'd like to say it was hard...but it only took a few minutes to modify the card and get it running with my home network.  Here's some pics.  The second one is a repeat, but you can see very clearly where I sanded on the card a bit to get it to fit nicely in the airport slot without putting stress on the keyboard.
