problem realtek 8723 driver

[Seldon]

Hello,

Im just trying to install ubuntu on a new computer. I installed ubuntu 12 but did not recognize the wireless device. It is a realtek 8723. I already found the drivers on other topic but I can not install them.

When I do make I get the following error:

make -C /lib/modules/3.2.0-23-generic/build M=/home/seldon/realtek driver/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012 modules
make[1]: Entering directory `/usr/src/linux-headers-3.2.0-23-generic'
make[1]: *** No rule to make target `driver/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012'. Stop.
make[1]: Leaving directory `/usr/src/linux-headers-3.2.0-23-generic'
make: *** [all] Error 2


I can not find a solution

I have already installed build-essentials and linux-headers-3.2.0-23-generic

unname-e gives me 3.2.0-23-generic

Anyone out there that can help me please

Thanks

I have already installed build-essential

Are you sure it's all in place?

sudo dpkg -s build-essential

I am very interested in your device, old driver dawg that I am. Please post:

lspci -nn | grep 0280

Thanks.

Thanks for answering

I did as you say:

When I do sudo dpkg -s build-essential I get:

Package: build-essential
Status: install ok installed
Multi-Arch: foreign
Priority: optional
Section: devel
Installed-size: 37

Architecture: amd64
Version: 11.5ubuntu2
Depends: libc6-dev | libc-dev, gcc (>= 4:4.4.3), make, dpkg-dev (>= 1.13.5)
Description: .....


When I do lspci -nn | grep 0280 I get

[0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8723]


It seems the package is well installed, no idea why I can not do make.

Thanks for the help

I downloaded the packages here: http://askubuntu.com/questions/13963...not-recognized

I extracted and made the files perfectly without even a warning. The only thing that may be different is that I built after sudo su:

cd Desktop/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012
sudo su
make
etc., etc.

I don't know if the 'make install' installs the firmware properly, we'll need to look at that.

Please try with sudo su.

The files I am trying to install I got them from the same thread you mention.

I also used sudo su before running make and getting the error on the first message.

Thanks for the help

Please try, with a wired ethernet connection:

sudo apt-get install --reinstall build-essential
sudo apt-get install --reinstall linux-headers-generic
sudo apt-get install --reinstall linux-headers-`uname -r`

Those tickmarks are on the left side of my US keyboard on the same key with ~.

Now try again.

I did as you say and I still have the problem when I do make (after sudo su)

The error is still:

make -C /lib/modules/3.2.0-23-generic/build M=/home/seldon/realtek driver/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012 modules

make[1]: Leaving directory `/usr/src/linux-headers-3.2.0-23-generic'
make: *** [all] Error 2

Any other ideas? Thanks

I am still mystified. What directory are you starting from? Is the Makefile located in the working directory?

ls

I get, for comparison:

root@LAPTOP60:/home/chili/Desktop/Forum/Seldon/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514 .2012# make

etc., etc.

Yikes!! By any chance, is the directory named 'realtek driver'? Linux and the terminal don't like spaces in directory names very well. If so, please rename the directory to realtek and try again:

cd ~/realtek/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012
sudo su
make
make install
modprobe rtl8723e
exit

EXCELENT!! it was the space in the folder, a really stupid error. I am writing this reply using wi fi conection.

Thanks a lot for the help and for being patient and for spending time reading my posts.

Thanks.

Now I need to see how to make the sound work (new computer!)

Regards!

Glad it's working and I'm glad to know how to get this new device working. Have fun!
