    Re: 12:04 LTS, Toshiba Satellite L850, RTL8111/RTL8168 WiFi non existent. HELP

    OK, wireless option is back, that's the good news. Still no modem, printer and/or neighbours wifi connections though!

    tristan@tristan-Satellite-L850:~$ cd Desktop
    tristan@tristan-Satellite-L850:~/Desktop$ sudo cp rtlwifi/* lib/firmware/rtlwifi/
    [sudo] password for tristan:
    cp: target `lib/firmware/rtlwifi/' is not a directory
    tristan@tristan-Satellite-L850:~/Desktop$ sudo cp rtlwifi/* /lib/firmware/rtlwifi/
    tristan@tristan-Satellite-L850:~/Desktop$ sudo modprobe -r rtl8192ce && sudo modprobe rtl8192ce
    tristan@tristan-Satellite-L850:~/Desktop$

    (Yes, admitedly, I made a typo in my first try. Oooopppps.

    Thank you again for your time. Let's try again (your) tomorrow!

    Re: 12.04 LTS, Toshiba Satellite L850, RTL8111/RTL8168 WiFi non existent.

    chili555 (or other):

    I seem to be in the same boat as Tristan57, or near to it. I also have a Toshiba Satellite and am having the exact same issue. I've followed along with the above thread but am getting slightly different results. The bottom line is that I managed to get Wireless Enabled but when I rebooted it went away. Now I'm back to square one.

    I have about as much understanding of this as Tristan57 in regards to tech knowledge and would appreciate anyone's help in getting the wifi on this box working (as that IS the entire reason I bought this machine in the first place!).

    ThankYouThankYouThankYou!!!

    Let's see, more specifically, what your results are:
    Code:
    lspci -nn | grep 0280
    lsmod | grep rtl
    dmesg | grep rtl
    iwconfig
    Thanks.

    Hi, Peredur111's wife here, posting as him. I'm about to try the firmware update that worked for Tristan57. He was a bit frightened of breaking something. I, on the other hand, am completely willing to try to break it (because I know whatever I break can be fixed!).... I'll post here again soon to let you know if the firmware update worked. Excellent thread. Many thanks.

    Edit:
    Okay! I think I broke it. Woo hoo!
    Seems I have no PCI devices installed at all any more. (edit: no, that's not right. I don't have any "grep 280" devices any more. I assume that has something to do with the wireless network card.)
    My husband started by typing

    lspci -nn | grep 0280

    We got the exact result Tristan57 got: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01). My husband executed these two commands:

    sudo apt-get install linux-backports-modules-cw-3.6-precise-generic
    sudo modprobe rtl892ce

    He had the same results Tristan57 had ("Wireless Enabled" appeared in the ... whatever the up-down-arrow thing is. It disappeared after restarting the computer).
    I took over at this point. I skipped most of the steps Tristan57 took. I started by downloading rtlwifi.zip, extracting it, and copying the files to /lib/firmware/rtlwifi/.
    I then unloaded and reloaded the driver using command string

    sudo modprobe -r rtl8192ce && sudo modprobe rtl8192ce

    "Wireless Enabled" appeared again. Upon restart, it disappeared again. NOW when I execute

    lspci -nn | grep 0280

    NOTHING happens. When I try lspci -nn I see a list of many Intel items

    00:00.0 Host bridge [0600]: Intel Corporation Ivy Bridge DRAM Controller [8086:0154] (rev 09)
    00:02.0 VGA compatible controller [0300]: Intel Corporation Ivy Bridge Graphics Controller [8086:0166] (rev 09)
    00:14.0 USB controller [0c03]: Intel Corporation Panther Point USB xHCI Host Controller [8086:1e31] (rev 04)

    00:1a.0 USB controller [0c03]: Intel Corporation Panther Point USB Enhanced Host Controller #2 [8086:1e2d] (rev 04)
    00:1b.0 Audio device [0403]: Intel Corporation Panther Point High Definition Audio Controller [8086:1e20] (rev 04)
    00:1c.0 PCI bridge [0604]: Intel Corporation Panther Point PCI Express Root Port 1 [8086:1e10] (rev c4)
    00:1d.0 USB controller [0c03]: Intel Corporation Panther Point USB Enhanced Host Controller #1 [8086:1e26] (rev 04)
    00:1f.0 ISA bridge [0601]: Intel Corporation Panther Point LPC Controller [8086:1e59] (rev 04)

    01:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR8162 Fast Ethernet [1969:1090] (rev 10)

    but no Realtek anything. It's as though the -r worked but the reload did nothing. Maybe I'm barking up the wrong tree here, but I see no rtl8192ce file in the zip file...

    Edit 2: the other two commands

    lsmod | grep rtl
    dmesg | grep rtl

    do nothing either (I guess because there is no rtl module installed any more?).

    Edit 3:
    I almost forgot a very important bit: the error messages:
    peredur@peredur-laptop:~/Downloads$ sudo modprobe -r rtl8192ce && sudo modprobe rtl8192ce

    WARNING: All config files need .conf: /etc/modprobe.d/Untitled Document 1, it will be ignored in a future release.
    peredur@peredur-laptop:~/Downloads$

    I assume it should not matter that I am in the Downloads folder...? I did copy the files over to /lib/firmware/rtlwifi...

    I forgot; one more thing you asked me to do:

    peredur@peredur-laptop:~$ iwconfig
    eth1 no wireless extensions.

    lo no wireless extensions.

    Hi, Peredur111's wife here, posting as him. I'm about to try the firmware update that worked for Tristan57. He was a bit frightened of breaking something. I, on the other hand, am completely willing to try to break it (because I know whatever I break can be fixed!).
    I love it!!! A person after my own heart! I actually have an old laptop that I use for just such purposes: tweak it until you break it. It's fun and I've learned a lot, especially what NOT to do!

    Let's take the easy things first.
    WARNING: All config files need .conf: /etc/modprobe.d/Untitled Document 1, it will be ignored in a future release.
    It appears that someone, let's blame your hapless husband, tried to create a document in /etc/modprobe.d but forgot to give it a useful name. Let's give it a useful name and then examine it and see if we need it or if we can remove it.

    Linux hates spaces in file names. We can get around that with the auto-complete feature. Please type in a terminal:
    Code:
    sudo mv /etc/modprobe.d/Untitled
    Press Tab. The remainer should fill in so it looks like:
    sudo mv /etc/modprobe.d/Untitled\ Document\ 1
    Then fill in where you want the file moved (mv) to like this:
    Code:
    sudo mv /etc/modprobe.d/Untitled\ Document\ 1   /etc/modprobe.d/test.conf
    Press Enter. Now we have the needed .conf and a name without spaces. Whew!

    Now let's examine its contents:
    Code:
    cat /etc/modprobe.d/test.conf
    Is there anything meaningful in there? If not, remove it:
    Code:
    sudo rm /etc/modprobe.d/test.conf
    If you are in doubt, post it here and we'll proceed.

    Wow! If hat was the easy one, how hard is the hard one?!?
    lspci -nn | grep 0280

    NOTHING happens. When I try lspci -nn I see a list of many Intel items
    The fact that your wireless card appears and disappears is very serious. It suggests several possibilities:

    * An ACPI problem in the system. Check:
    Code:
    dmesg | grep -i -e error -e warn
    Try resetting the BIOS to defaults; F9 in some BIOS.

    * An electrical defect with the wireless card itself. It may be failing.

    * A poorly seated wireless card. In many laptops, there is a door on the bottom to access the wireless card. After carefully following all the procedures outlined in the service manual, carefully wiggle the card out and back in, seating it solidly but not forcing it.

    We will have no luck enabling a wireless card that's in a coma or deceased.

    Re: 12.04 LTS, Toshiba Satellite L850, RTL8111/RTL8168 WiFi non existent.

    The card is definitely not deceased or in a coma, as this morning (before doing any of your instructions) we have wireless and can see neighbors' networks. I'm rooting for "poorly seated" right now but betting on "failing." Thank heavens this laptop looks like it's easy to open.

    For curiousity's sake I did

    dmesg | grep -i -e error -e warn

    first and got a string of errors and warnings.

    peredur@peredur-laptop:~$ dmesg | grep -i -e error -e warn
    [ 0.436572] pci0000:00: ACPI _OSC request failed (AE_ERROR), returned control mask: 0x1d

    [ 12.294694] EXT4-fs (sda2): re-mounted. Opts: errors=remount-ro

    and then:

    peredur@peredur-laptop:~$ lspci -nn | grep 0280
    02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)

    (why looky there! It's baaa-aack!)

    Now I'll go do the stuff you told me to do first.

    I hope I don't drive you nuts; you're very VERY helpful and I am not being a good follower. I am deliberately poking around quite a bit as I try to fix this. It brings back memories from 1989-90 of green screens and geeky puns. I forgot how filled with geek-jokes Unix help files are. For example, at the end of man grep: "GNU's not Unix, but Unix is a beast; its plural form is Unixen."

    On a side note... can you explain "pipe," simply? Wikipedia's explanation is too dense for me.

    Now, I assume that moving and renaming files using the CLI is, really, the same as if I did it using the GUI, right?

    Untitled Document 1 (or rather, test.conf) is empty.

    peredur@peredur-laptop:~$ cat /etc/modprobe.d/test.conf
    peredur@peredur-laptop:~$

    Yes, my hapless husband seems to have created it yesterday evening while I was outside doing yard work. I have removed it. (More side notes: does Unity have a view like "details" in Windows? In the file properties can I mentally substitute the word "created" for "accessed?" And really, my husband isn't _that_ hapless - he's doing quite well with Ubuntu. He's even managed to install a program that had instructions written for GNOME, not Unity.*)

    Now I'm going to go further than you told me to, and try installing that module again.

    peredur@peredur-laptop:~$ sudo modprobe -r rtl8192ce && sudo modprobe rtl8192ce
    peredur@peredur-laptop:~$


    Hey hey, no errors or warnings! Restarting now.... and we still have wireless. Good.

    I still get the same errors and warnings with this, though:

    peredur@peredur-laptop:~$ dmesg | grep -i -e error -e warn
    [ 0.432785] pci0000:00: ACPI _OSC request failed (AE_ERROR), returned control mask: 0x1d

    Hm. What IS the meaning of the rts5139 line?

    Now I'll go reset BIOS to defaults. BRB with more.

    Edit:
    Reset BIOS. No changes to error messages.

    * "GNOME not Unity?" Down the rabbit hole we go...

    Hmmmm.... I'm having trouble accessing the BIOS. I'm not sure what F-key to press so I'm trying them all. Interestingly enough, when I use F1, F2 or F8 I can see, briefly, text that says, "error ...(doing something),... broken pipe...(something)." About 12 lines go by too quickly for me to see what's going on. But "broken pipe?" I don't like that. There must be a way to capture that text...
