Wireless card
Laptop internal wireless network cards also know as WLAN card or Wi-Fi card come in different shapes ans sizes. On the picture above you see two most common internal wireless card types found in laptops.
Two wireless cards on the top have Mini PCI form factor connector and found mostly in older laptops.
Two wireless cards on the bottom have Mini PCI-E (Mini PCI Express) form factor connector and found mostly in newer laptops.
Mini PCI-E connector is not backward compatible with Mini PCI connector. In other words, you cannot install a Mini PCI-E wireless card into the Mini PCI slot.
The wireless card plugs into the Mini PCI or Mini PCI-E slot on the motherboard. Most internal cards have two small connectors for wireless antenna cables, some newer Mini PCI-E cards have three connectors and require three antenna cables.
On the picture below you see an internal Mini PCI wireless card connected to the laptop. As you see, there are two antenna cables connected to the card. One main antenna cable and one auxiliary antenna cables.
In order to remove the wireless card, you’ll have to disconnect the antenna cables first. Grab firmly the antenna connector with your fingers and unsnap it from the card. Do the same with the second antenna cable. After that you remove the wireless card the same way as you remove the RAM module.
1. Spread latches on both sides of the card with your fingers and the card will pop up at a 20-30 degree angle.
2. Carefully pull the wireless card from the slot.
On the picture below you see a newer Mini PCI-E wireless card pluged into the slot on the motherboard. In my example the card has three antenna cables. Many Mini PCI-E cards have only two antenna cables.
This card connects to the motherboard differently than a Mini PCI card. Ther are no latches on the sides. The card is secured to the motherboard by two screws.
In order to remove this card:
1. Disconnect all antenna cables from the card. Do not forget to make a note how cables are connected.
2. Remove two screws and the card will pop up at a 20-30 degree angle.
3. Carefully pull the wireless card from the slot.
On some laptops the internal wireless card could be accessed throught the hatch on the bottom, on other laptops it’s hidden under the keyboard or laptop cover.

james,
These antenna cables should be connected to the wireless card. How to connect them? It depends on the model of your laptop, but I think it shouldn’t matter.
You can try Main-gray, Aux-black.

My two wire antenna (Main and Aux) was disconnected in my mother board.. can you tell me where part of motherboard should i connect the black and grey wire?

MARK,
1. Try reconnecting the wireless card, maybe it’s not making good contact with the slot. Remove the wireless card from the slot and plug it back in. It’s possible that after reconnecting the card it will appear in the network connections.
2. Try reinstalling the wireless card driver. Download it from the Gateway website and run.
3. Finally, try reinstalling Windows. It’s possible you have corrupted software. Backup all personal files and run the recovery disc. Reimage the hard drive back to factory defaults.
If the cannot get it work, it’s either bad Wi-Fi card or motherboard problem.

I have a Gateway MA2 laptop and my wireless connection in network connections disappeared. I have looked in the device manager under network adapters and it only shows the 1394 LAN adapter. I cannot figure out how to connect using wifi without this connection. Any suggestions?

gabba,
I’m not sure if the Intel card will work in your laptop, but Toshiba has an Atheros a/b/g/n card listed for Satellite A215-7422.
Here’s the part number for that card: V000090370. Google the part number and you’ll find it.
You’ll have to replace existing antenna cables with a new set. Here’s the part number for Toshiba antenna cables (a/b/g/n): V000100060.
The Wi-Fi antenna cables can be replaced. They are running inside the display panel and routed under the LCD screen. You’ll have to disassemble the display panel, remove the LCD and replace cables. The keyboard also has to be removed for that.
Here’s some help for your Toshiba laptop: http://www.irisvista.com/tech/

I have a Toshiba A215-7422 and would like to upgrade the wireless card to the Intel® Ultimate N WiFi Link 5300.Will this card work and would I be able to get wireless N performance or will I have to install another antenna? By the way can another antenna be installed?

Charled Dabney,
I believe they are 2 wires per wire. You’ll have to replace the antennas.
Same happened to me last week. I was fixing a laptop and accidentally separated the connector from the wire. I replaced the antenna cables after that.

mini pci-e connectors came apart from wire. can these wires just be re-soldered to connectors or are they like an RCA plug w/2 wires (per wire) + and – ?

Gerry,
You’ll have to find out if your laptop is “wireless ready”.
1. Do you have a slot for the wireless card?
2. Do you have wireless antenna cables installed?
3. Do you have wireless switch on the side?
If your answer is yes to all three questions, you can install the wireless card.
Take a look at this disassembly guide for a Satellite P10/P15 laptop. You can access the wireless card slot from the bottom of the laptop as it shown on the step 2.
Here are part numbers for the wireless card compatible with a Satellite P10 laptop: K000010210 and K000010220. Google the part number and you’ll find the card.

I have a toshiba satellite psp10e. I would like to fit an internal wireless card,is this possible and if it is which would you recommend

I have a Toshiba Satellite A10-S1001. Wireless is optional in this model and want to enable it. I’ve installed a Broadcom mini pci card and connected the antenna wires, installed the drivers etc. Windows sees the card and says it is working properly. My problem is that the wireless switch does not seem to work. It is very loose and won’t stay on one side or another. I’ve opened the case to take a look and it seems like there is nothing there to ‘switch on/off’. Any ideas on how I can make the internal wireless work? i.e. install a new switch, use an internal switch, or bypass the switch all together?

Art,
In a Portege 3500 the wireless card is hidden under the keyboard. Take a look at this disassembly guide for Portege 3500. You can access and remove the old wireless card if you follow steps 10-14.
Which newer card you should use? I don’t know which one will work for sure but you can try Intel WM3B2200BG wireless card.
This wireless card is not expensive and you can download driver from the Intel website here. Select your OS and download the driver.
I think you have a good chance this card will work with your laptop.

I have a Toshiba Portege 3500 and the wireless card does not support WAP security only WEP. I heard and tried about software upgrade (Atheros) and I install the most updated driver (as reported on the website CNET) to no avail. I cannot connect to a WAP wireless network. Can the wireless card of this computer be upgraded? If it is so, what card should I look for and how can I replace it?
Thanks!

Benny,
Did you check the device manager? Can you see the wireless card in the device manager? Is there a yellow exclamation sing by the wireless card?

William,
Thanks for the tip. I heard about this trick but wasn’t sure if it works or not. Just in case, here’s the part number for the internal wireless card in Satellite 1130/1135 laptops: K000002000. This wireless card should works fine with your laptop and the on/off switch should work too.
May 16th, 2009 at 12:17 pm
I purchased a wireless card for my Satellite 1130-S155 and it didn’t work at first. The vendor told me about a Toshiba fix…cover slots 11 & 13 with thin tape (I used regular Scotch tape) and reinstall. Not easy for a 70-year old with fat fingers but I did it and it’s worked just fine for months save for the inconsequential fact that the on/off switch doesn’t work.

John,
To make sure that your new wireless card is compatible with the laptop, I would recommend searching for a new one using the part number. Remove the faild wireless card from the laptop and search for the Toshiba part number on the sticker. Now google the part number and find a replacement card.
May 8th, 2009 at 8:48 am
I have a Toshiba Satellite laptop and I think my wireless card faild. The card is detected in the device manager and the light turn on but there is no connection. I teste my router with another laptop and it works fine. I tried reinstalling the driver without any luck.
My question is. How can I find a compatible wireless card for my laptop?

Mike,
Take a closer look at the side and front of your laptop. Toshiba laptops have a small switch for the wireless card and it’s possible that your son just turned it off. The switch could be very small ans some people don’t even know it exists. Usually you’ll find a small LED close to the switch. When it’s turned on the LED lights up. Maybe your some accidentally turned of the switch and disabled the wireless card?

Need help here! I was working on my Toshiba laptop and everything was fine, the wireless connection was working, I was browsing the internet. I went to the kitchen and when I came back my four years old son was already there. I think he did something because my wireless connection disappeared. I cannot reconnect to the router! I tried rebooting a few times but no luck! Could he disable the wireless somehow? I just cannot figur it out. Please help if you can.
Mike.
