    Re: Inspiron 15R 5520 failure to detect wireless device

    I am a complete beginner when it comes to this, but this is what I tried:
    1. I copied the .deb files (all of them) to the /home/user/ directory
    2. I tried installing them with
    Code:
    sudo dpkg -i pkg.deb
    3. This worked for the two Bluetooth ones, but the "wireless-bcm43142-dkms-6.20.55.19_amd64.deb" and the "wlan_amd64.deb" packages failed to install, giving the following output:
    Code:
    user@ubuntu:~$ sudo dpkg -i wireless-bcm43142-dkms-6.20.55.19_amd64.deb
    [sudo] password for user:

    Hi,

    I have tested this on Fedora 17 Kernel 3.5.4. The driver is working.

    There is a small problem. This driver does not support Wireless N.

    Did I miss something?

    Hi jawadjee,

    I tried the command you posted to no avail. I then downloaded the dkms package for Dell from http://linux.dell.com/dkms/permalink/ and installed the .deb file, then installed both the wireless .deb files. I restarted, and lo! my laptop started picking up wi-fi signals.

    Thanks a million.

    If anyone manages to get it working (actually associating to an AP) on linux >= 3.6-rc7 please follow-up on this:

    Frankly, if you're connected to the internet, there's simply no excuse for this level of ignorance. It's willful. - tsm_sf on /.

    Reposting updated link, as I'm getting emails about it. it's also
    mentioned at the bottom of the homepage jas.gemnetworks.com
    http://jas.gemnetworks.com/debian/pool/main/w/wireless-bcm43142-dkms_6.20.55.19_amd64.deb

    P.S. It works just fine with 3.5.x, but for 3.6.x, you need to spam broadcom for support,
    http://marc.info/?l=linux-wireless&m...9572204130&w=2

    .. especially since they haven't updated their linux drivers page in over a year, and this (6.x) driver isn't even listed on their site: http://www.broadcom.com/support/802.11/linux_sta.php
    Better yet, spam them to open source their drivers, or at least release specs for their PHY's so people can start developing opensource drivers for these cards, because broadcom fails to maintain their own linux drivers

    Workaround

    replace line 50:
    Code:
    #include <asm/system.h>
    with:
    Code:
    #if LINUX_VERSION_CODE < KERNEL_VERSION(3, 4, 0)
    #include <asm/system.h>
    #endif
    Rebuild/install:
    and finally `modprobe wl`. Enjoy your new 3.4 kernel w/ working wifi

    UPDATE 13-Sep

    I have updated the bcm43142 driver package, with the following changes:
    1. One-line change of the call ndo_set_multicast_list to ndo_set_rx_mode as described here , so that it compiles on Kernels 3.2.x. This seems more proper than commenting out the line that uses the said call as others have done!
    2. Incorporated my changes outlined above so that it compiles on kernels 3.4.x (Might need a few more changes to compile on 3.5.x?)
    3. Updated md5sum of the modified wl_linux.c file (per 1 & 2 above)
    4. Removed "oneiric" (which is reference to Ubuntu 11.10) from package name, and all directory & path-names everywhere in the package contents, as it is no longer ubuntu/oneiric -specific.

    Get the updated deb package here: http://jas.gemnetworks.com/debian/wi...5.19_amd64.deb

    Please see post #18 in the following link: https://answers.launchpad.net/ubuntu...uestion/200767

    Maybe someone working on 12.04 64 bit might like to test ist.
    It works for me - on Dell Inspiron 5520 with Ubuntu 12.04 64 bit. Thanks for the link!

    Re: Inspiron 15R 5520 failure to detect wireless device

    Hi all,
    I got the wireless working on Xubuntu 12.10 64-bit with 3.5 kernel.

    Code:
    uluroki@nayan5520:~$ uname -r
    3.5.0-17-generic
    Code:
    uluroki@nayan5520:~$ lspci -nnk | grep -iA2 net
    07:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller [10ec:8136] (rev 05)
        Subsystem: Dell Device [1028:056a]
        Kernel driver in use: r8169
    --
    08:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)
        Subsystem: Dell Wireless 1704 802.11n + BT 4.0 [1028:0016]
        Kernel driver in use: wl
    First I started with solutions in this tread, but it did not help.

    Then I tried https://answers.launchpad.net/ubuntu...uestion/200767
    but there was some sort of a problem with the kernel, as mentioned in
    http://askubuntu.com/questions/17510...stro-3460-3560

    Finally, http://askubuntu.com/questions/17835...-4-3-5-kernel/ worked for me.

    Oh, and don't forget to
    Code:
    uluroki@nayan5520:~$ sudo modprobe wl
