    This post is to help people wanting to install WWAN in their CF-19MKI. I searched all 101 pages of the Panasonic forum and could not find a definitive answer on how to accomplish this. Hopefully this helps a few people out that want to install AT&T WWAN service into their CF-19.

    (FYI...I am not responsible for what happens to your laptop if you attempt this. It was your choice to try this modification. Sorry had to post this as the US is fast becoming a "Sueish" place.)

    The WWAN card that I installed in my CF-19 is a mini pci-e card that removed from an AT&T Sierra Wireless AirCard 875U. This is a USB adapter that has a mini pci-e card inside of it. Some people will probably wonder why I used this instead of buying just a mini pci-e card. Well I got the 875U for $35 with free shipping from ebay. This is significantly cheaper than just buying the bare card. Just do a search on ebay for an "att 875U" and you will get a number of hits. The specs can be found here:

    ATT Sierra Wireless AirCard 875U

    You have to remove the battery lid and remove a couple of screws then pry the case apart. Once the case is pulled apart partly, undo the antenna that is connected to the card. Now you can open the case all the way, remove a couple more screws, then remove the card.

    To install the card into my CF-19, I removed the screws which cover the pci-e slot on the bottom back of the case. If you take the cover off and you see the system memory then you took off the wrong cover. Replace that cover and remove the other one.

    Once the cover is off, install the card into the pci-e slot that you will see. You will have to find some screws to hold the card down. I had some screws laying around from some netbooks I've taken apart and used those. The screws which hold down the card in the original case for the WWAN card may work but I am not sure. Once you have the card secured to the motherboard you have to connect the antennas. I am not sure about this part as I could find no info on this but I used the u.fl connectors that were plugged into the board next to the pci-e slot. I unplugged them from the board and plugged them into the card. The last thing you have to do before you reinstall the cover is to set the dip switches next to the slot. I turned on switches 1 and 2. Once this is done reinstall the cover. I then installed the SIM card into the SIM slot that is located under the cover of the headphone and mic ports. You have to remove a small steel cover to insert the card. I am not sure if you have to put the cover back on after the SIM card is installed but I did.

    Next is the fun part. Turn the laptop on and hope you don't smell smoke lol. Hit F2 and go into your BIOS. Under the Advanced menu you should now have a setting for Wireless WWAN. Enable this then hit F10 to save and exit. Boot into Windows and make sure the wireless switch is turned on. Your computer will detect new hardware. Let it do it's thing. It may or may not install the correct drivers. This will be taken care of when you install the ATT connection manager which can be downloaded here:

    ATT Connection Manager

    Download and install that software and then reboot once it is complete. When you computer comes back up, fire up the ATT connection manager. Your card should now be detected and a Connect button should show.

    This worked for me. I have successfully connected to the ATT network at 3G speeds. If you want GPS capabilities built into it that is NMEA, look for the 881U card. I have yet to test this. You may have to update the firmware to enable this. The firmware can be downloaded at the first link I posted.

    Hopefully this helps some people. I've seen others post that they finally got theirs working but as per usual like every other forum, they fail to let everyone know what they did to make it work and are never seen again.

    Thats a great post Tristan

    The forum is not only here to help people troubleshoot problems, but to show and help people modify their Toughbooks

    Thats great that you were willing to take some chances with the unknown

    I am waiting to see what some of the experts here have to say about the Mod

    If you remove your side antenna covers on your lcd lid you should see the antenna wires going into the different antennas on the sides
    They are each a different colour, and each antenna is marked to let you know what it is for, so you will be able to trace the wire colour that is connected to the wwan ant and see if it matches the colour on the two wires that you connected

    A little bit of time ago, I had installed a Sony-Erricson F3507g PCI-E -card in my CF-19. This HSDPA-Card has also an included GPS-receiver. First I have to found out, which of the antenna-connectors from the card is for GPS and which one for WWAN. After that I installed an small embedded GPS-antenna from an Cellphone (Nokia E75) on the right top side of the lid, because I don't live in the US and I don't have to use the EDVO-US-antenna. For Germany I have to use the brown antenna-cable with the antenna on the bottom left of the lid. I unsoldered the black-antenna-cable from the US-EDVO-antenna and soldered the mobilphone-GPS-antenna on the cable, which I glued on the WWAN-antenna. In an other thread u will find some pics from the location of the antennas ( http://forum.notebookreview.com/showthread.php?t=360283 ).
    The problem with the F3507, also known as Dell 5530: the windows driver will not work on every notebook, also not on the CF-19. The driver itself is locked to special notebooks from Dell, Lenovo and MSI. I wrote an e-mail to sony-erricson, but they are not willing to write or to give a driver to an not certified notebook nor the sourcecode.:mad:
    But I'm using also ubuntu on my CF-19 and their it is fully working :p , also the GPS (but the receiption is not so good, like on my CF-29...)
    Now I'll hunting for an 875U. Thank u for entry!

    ...It's good against lost of electrical connection under vibrations....

    Good bit of scrounging there Tristan! Of course once the leeches find out about that model adapter, they'll prolly double in price overnight!

    Just out of curiosity... do you have a mini-pciE SSD laying around? I'd be curious if your old husk could be used to fire one up on a USB port...

    Just for fun I tried to install a mini pci-e 64GB RunCore SSD card in the slot I used in my Dell Mini 9. I'm sorry to tell you...It didn't work. I tried all sorts of dip switch combinations and it just wouldn't show up in the BIOS or OS. I was hoping that even though it didn't show in the BIOS it may show up in the OS...sorry dude.

    Thanks dude! There is so little information when it comes to these specific laptops and every little bit helps in my eyes. Sort of a "pay it forward" type of thing...

    Yeah, I kindof figured that would be the case. Prolly some BIOS restriction...

    So I had success to get an 875U from the UK. It's a little bit curious, but a good looking construction. Why are they using a battery?
    The first thing: I had no luck, to update the firmware. The updater says 'not correct device'. Could u pls provide the link to the exact firmware? Maybee I'm using the wrong version.
    Nxt is, there is only one antenna-connector on the pci-e-card MC8775. The second is not on the pcb, but I see the contact-structure, so i'll try to soldering one on the pcb and hopefully with the new firmware and the new connector it will receive the GPS-signal.
