This tutorial explains how you can install internal wireless card into an older laptop. I assume that your laptop is “wireless ready” which means it has a slot for the wireless card and equipped with wireless antennas, but missing the wireless card. Why did I make this tutorial for an older laptop? Because all new laptops are sold with the wireless card.

I’ll take as an example my Dell Latitude C840 laptop. As you see on the picture, it has a slot for the wireless card and one antenna cable. That’s strange, most laptops have two antenna cables, white and black. One cable goes to the main connector on the wireless card, another cable goes to the auxiliary connector. Probably you’ll ask me which antenna cable connects to which connector? I think it doesn’t really matter because both antenna cable are identical.

My main concern was finding the right device driver for the wireless card I plan to install into my laptop. As you know, without correct driver it will not be recognized by the operating system and will not work at all.
Likely, I have a spare wireless card from another not working Toshiba laptop and this card worked perfectly.
You can find this wireless card by the model number: WM3B2200BG. Just search by the model number here and you’ll find one for about $20. It’s a 802.11 b/g wireless card, so you’ll get a 54Mbp/s connection as I did.

In order to install the wireless card into the slot, just push it into the slot at a 30 degree angle (step 1) and then press on the card (step 2) until it’s locked.

After the card is locked in the slot you can connect the antenna cable. In my case, I snapped the antenna cable on the main connector. If you have two antenna cables, snap one of them on the main connector on the wireless card and another one on the auxiliary connector. As I mentioned before, I don’t think it matters with cable goes to which connector. Both antenna cables are identical.
Finally, you’ll have to download and install the wireless card driver. If you use the same card as I did (WM3B2200BG), you can download driver from the Intel website here.
Use this link: Intel® PRO/Wireless 2200BG Network Connection. Select the operating system, download and install the driver.
You have a couple of different options:
1. Download and install the driver only. Use this option if you want to use Windows wireless connection utility. That’s what I did because I prefer using Windows tools.
2. Download and install both the wireless card drive and the connection software. Use this option if you want to use Intel’s software application. It’s totally up to you.

As you see on the picture above, the wireless card successfully connected to the wireless access point at 54Mbp/s.

Update: Today in the morning I turn on the Thinkpad and voila! it is recognised and the driver works great… then I connect the antena and puff, the card gets the ! sign again. Then I remember that I have read somewere about using a “heater” to repair a card, I don’t have one of those “heaters” then I hold the card close to kitchen fire (sorry don’t remember the name, I only speak spanish) and then the card works fine, I even catch some wireless networks. The problems were not the driver but Hardware. Thank you for your time.

David Lopez,
Not sure what’s going on. I think if you are using a wm3b2200bg wireless card, the 2200gb driver from Intel site should work.
I know that some people were experiencing a problem installing Wi-Fi cards into ThinkPad laptops because they didn’t use “IBM certified cards”.
I guess your laptop can see the card but doesn’t know how to handle it because this card is not ” IBM certified”. That’s my guess.
Are you using Intel driver or you found it on IBM (Lenovo) site?

Greetings, Thanks to this article I get the idea to use an wm3b2299bg wireless mini pci card from a defective hp and use it into an IBM thinkpad. It is recognised by bios and windows but I can’t get the bloody Driver, I have download several 2200bg drivers but I allways get message The location does not contain drivers for the hardware. Any Idea what’s going on? is there more than one intel wm3b2200bg? does it have a BlueToot too?. I work with windows since Win 3.1 and I have never fail finding a Driver. (I install a Ubuntu OS and it seems to find a device 8006:4220) Thank you.

Eric,
I don’t think that the wireless card produces any heat at all. Even if it does, it will not affect the hard drive.
