    Hi All
    Per the title. I would like to fit a WWAN card to my L501x.
    It does have the SIM slot beneath the battery.
    From reading the forum I think the part is a 5540.

    Anything else I need to know/how difficult is the fitting. Are the antenae already installed etc.

    Any assistance really appreciated.

    Installing is easy, a cave man can do it. You just open the bottom plate and insert the card into the slot. Though they might not have included a screw that holds the card in place and the antenna since you didn't have the card. Screw shouldn't be too big of a problem, you can check out the one on the wireless card(they are right next to each other) and find one somewhere. And if you have 2-3 extra cables in the place(they might be hidden under the card slot, which requires disassembling pretty much the whole rig to pull out)you should have the antenna installed, don't count me on this though.

    i've been thinking of doing it to my l502x which has the extra antenna cables for wwan.
    if you don't have these extra antenna cables i heard (on the alienware m11x forums) you can use the auxillary antenna cable from the wifi card for the wwan

    I've wondered with this - how does the WWAN card read the SIM? The card only has the 2 antennae and no direct connection to the SIM slot. Maybe it uses smbus...

    I guess you're going to get a poorer signal if you use a single WiFi antenna rather than the 2 WWAN ones so might be worth checking that first?
