    Re: Inspiron 15R 5520 failure to detect wireless device

    Hi,

    I'm too having the same problem on my new Dell Inspiron n5720 17r. I got it with preinstalled Ubuntu 11.10 where everything works ok. After adding Mint 13 Maya 64-bit with cinnamon wireless is dead.
    On Ubuntu 11.10 I find that the driver is called wl0
    I don't know if this would help, but there is a bug report which I'm waiting to resolve:

    Re: Inspiron 15R 5520 failure to detect wireless device

    I have a Dell d400 laptop i am having the same problem getting the onboard wifi card to work as well. I believe it is the broadcom 4306 card. played with it for 3 days, went to my local flea market on sunday since there is usually a guy there with dell recovery disks, was going to just put windows back on it even though i cant stand windows.... couldnt find him so bought another pcmi card and so far it works reasonably well. drops the connection sometimes, but the wifi in my local starbucks is known to act stupid at times so dont know if it is a wifi card issue or the wifi at the starbucks. tend to think it is an issue with the wifi at starbucks since it always reconnects on a restart and drops at different times usually when the wifi indicator goes below 2 bars of signal strength for longer than a few seconds. I have talked to a few people that use ubuntu and other forms of linux and they ALLsay that broadcom devices are a royal pain in the a**

    Well, your colleagues haven't used Linux in awhile. That used to be the case but Broadcom and the majority of their wireless cards, since the advent of the b43 driver, play nice.

    Very new hardware of any brand can be problematic, even with co-operative vendors. Seems to be Win, then Mac, then Linux for drivers.

    I too have a new 15R 5520 that i just installed 11.10 on. Wireless does not work. dmesg reports

    iwlagn 0000:02:00.0: request for firmware file 'iwlwifi-2030-5.ucode' failed.

    There is a *2030-6.ucode in /lib/firmware but no -5 .... sigh

    I had hoped since 15R was Ubuntu certified that Ubuntu would work, but I guess a model still has lots of different hardware options, so the certification only applies if you can match the config of the certified model. ugh

    I also have a horizontal flicker line at the top of the display (3 or 4 pixles in height)

    I'm running updated 11.10 3.0.0-23-generic-pae
    hardwired ethernet works

    I think iwlwifi is for intel wireless cards! If you have broadcom wireless then you'll be needing bcmwl driver (bcmwl-kernel-source)

    Ndiswraper doesn't help or I installed not right driver (Network_Broadcom_W7_A01_Setup-WTD28_ZPE.exe).
    Some information:
    Code:
    :~$ ndiswrapper -l
    WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.
    bcmwl6 : driver installed

    :~$ lspci -nnk | grep -iA2 net

    Also I've found this: http://askubuntu.com/a/175115 (Broadcom Corporation Device [14e4:4365] too). I've tried to install it - all is OK, this driver is shown in 'Additional drivers' as currently in use... but it doesn't help too! Why? Maybe laptop model doesn't matter so I can't understand why.

    Please create another thread with a descriptive title and as much info as you can provide about your issue. Gets confusing when you hijack another thread and helpers are attempting to fix two issues from two separate posters. (And confusing for the original poster.)

    Also, this is a pretty old thread now, and you will have more chance of getting help, and more specific help, with a new thread.
