My Realtek 802.11n WiFi card isn't being claimed by the drivers from here. I installed led the drivers using the install.sh script given in the decompressed tar.gz. UbuntuMATE is running on a Raspberry Pi 2.

*-usb:4 UNCLAIMED
             description: Generic USB device
             product: 802.11n NIC
             vendor: Realtek
             physical id: 5
             bus info: usb@1:1.5
             version: 2.00
             serial: 00e04c000001
             capabilities: usb-2.10
             configuration: maxpower=500mA speed=480Mbit/s

Above is the result of sudo lshw in terminal, which shows the unclaimed USB device, the WiFi card.

Running lspci (I'm not even sure if this is relevant) gives:

Running install.sh gives the error:

As I'm new to Linux in general, I have no idea as to where to go from here, so I'd appreciate any help. If you need any more information, just ask and I'll post it.

  • Yea I know this is kinda ironic, but using drivers from hardware manufacture's site is rarely to be a good idea, as the they're usually out-dated like in your case: the latest kernel they support is 3.9, and you're using 3.19 (I guess, pls provide this info). And we also need your card serie (is that rtl8712?) And where did you get your driver installation script? Try reinstall make, install build-essential, checkinstall and try again. – McSinyx Jul 31 '15 at 2:49
  • The install script is the one provided in the driver download. Not sure what series, the packaging was really minimalist and of low quality (guess that shoulda' been a warning to me!) It may be rtl8721. Running uname -r gives 3.18.0-20-rpi2. The issue with installing from apt-get is that requires internet connection, something I'm trying to get to work. – HarryCBurn Jul 31 '15 at 13:26

I've just found out that your chip is actually rtl8192eu. As far as I know, there is no driver for it in Ubuntu's repo. However, as v0yAgEr mentioned on OSMC forums, there is driver for that chip works for kernel version 3.18 on GitHub. I modified v0yAgEr's tutorial to a way hopefully would work for you:

  1. Install build-essential:

    • From the computer have Internet access, go to Ubuntu Packages, download build-essential, its dependencies and its dependencies' dependencies to a folder called bldessen
    • Copy that folder to your Pi, then install all the debs by sudo cd bldessen && dkpg --install *.deb

  2. Download the driver from GitHub (click the Download Zip button), copy to your Pi, then extract it: unzip rtl8192eu-master.zip

  3. Compile your driver:

    cd rtl8192eu-master
make ARCH=arm
sudo make ARCH=arm  install
sudo bash -c 'echo "options 8192eu rtw_power_mgnt=0 rtw_enusbss=0">/etc/modprobe.d/8192eu.conf'

  4. Test if the driver loaded:

    modprobe 8192eu
modinfo 8192eu

  • Spent a few (3-4) hours installing dependencies. Finally got make to work, and got an error when trying to build. I've pasted it here. Any ideas? – HarryCBurn Aug 1 '15 at 23:54
  • I've no idea why it failed. But make install need to be ran with root permission, i.e. via sudo or su -c. – McSinyx Aug 2 '15 at 13:57
  • Installed linux-headers, compiled fully. – HarryCBurn Aug 3 '15 at 19:00
  • So @HarryCBurn is your problem solved now? If my answer helpful then I'd be really grateful to see it got accepted. – McSinyx Aug 5 '15 at 13:25
  • Still having , but they're on my end, so I've accepted. Thanks! – HarryCBurn Aug 5 '15 at 13:32
