rtl8723be wireless driver installation

[initzero]

Hello,

root@kali:~# lspci -nn | grep Network
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]

im trying to install the rtl8723be wireless driver from here: http://github.com/lwfinger/rtl8723be

Every time I try to make i get this errror:

root@kali:~/rtl8723be# make
make -C /lib/modules/3.14-kali1-amd64/build M=/root/rtl8723be/rtl8723be modules
make[1]: *** /lib/modules/3.14-kali1-amd64/build: No such file or directory.  Stop.

I know /lib/modules/../build should be some link to the linux headers. I installed all available headers with apt-get install linux-headers* , but i still cant install the driver.
Is there a possibility to install ./firmware/rtlwifi/rtl8723befw.bin directly, or is this not a module?

I hope you can help me

Edit: I just saw this: http://forums.debian.net/viewtopic.php?f=7&t=116559 does that mean i have to wait for the next kali version?
How close is the developerteam to publishing?

Hi there!

Well I have some spare time today, so here it goes:

Download the driver if you haven't do that already:

git clone https://github.com/lwfinger/rtl8723be

Install linux headers:

apt-get install -y linux-headers-"`uname -r`"

Now if you try to compile it you will see something like this:

....
....
/root/rtl8723be/rtl8723be/trx.c: In function ‘rtl8723be_rx_query_desc’:
/root/rtl8723be/rtl8723be/trx.c:621:3: error: implicit declaration of function ‘_ieee80211_is_robust_mgmt_frame’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[5]: *** [/root/rtl8723be/rtl8723be/trx.o] Error 1
make[4]: *** [_module_/root/rtl8723be/rtl8723be] Error 2
make[3]: *** [sub-make] Error 2
make[2]: *** [all] Error 2
make[2]: Leaving directory `/usr/src/linux-headers-3.14-kali1-686-pae'
make[1]: *** [default] Error 2
make[1]: Leaving directory `/root/rtl8723be/rtl8723be'
make: *** [all] Error 2

There is a typo(?) in /rtl8723be/trx.c file. So, open it and go to line 621

#if (LINUX_VERSION_CODE <= KERNEL_VERSION(3,14,0))
if ((ieee80211_is_robust_mgmt_frame(hdr)) &&
(ieee80211_has_protected(hdr->frame_control)))
#else
if ((_ieee80211_is_robust_mgmt_frame(hdr)) &&
(ieee80211_has_protected(hdr->frame_control)))
#endif

and remove the underscore "_" before "ieee80211_is_robust_mgmt_frame(hdr)) &&"
it should look like this:

#if (LINUX_VERSION_CODE <= KERNEL_VERSION(3,14,0))
if ((ieee80211_is_robust_mgmt_frame(hdr)) &&
(ieee80211_has_protected(hdr->frame_control)))
#else
if ((ieee80211_is_robust_mgmt_frame(hdr)) &&
(ieee80211_has_protected(hdr->frame_control)))
#endif

save it and run:

make
make install

It should compile and install correctly.

Make sure that module and firmware are install correctly: (i'm running i386 of Kali)
/lib/modules/3.14-kali1-686-pae/kernel/drivers/net/wireless/rtlwifi/rtl8723be/rtl8723be.ko
/lib/firmware/rtlwifi/rtl8723befw.bin

Finally you may want to run:

depmod -a
modprobe rtl8723be

Unfortunately I don't own a RTL8723BE based card to tell if the driver is working or not.
Please report back if you have positive (or negative) results. They should be helpful for other users also.

Good luck!

I've seen your posts.

Hey nice_the_greek,

i try ur fix, but it dosent work. My Code is allready without a "_". So i can fix anything.

Then i cant update the linux headers via: apt-get install -y linux-headers-"`uname -r`"

i get this message every time.

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package linux-headers-3.14-kali1-amd64
E: Couldn't find any package by regex 'linux-headers-3.14-kali1-amd64'

I hope anyone can help me

Thx xSK

Hi there xSK
You are right. I just re-download the drivers and the underscore "_" it's there. I've a made a mistake. It's line 621 not 622. As for the rest you can try:

apt-get update
apt-get install -y linux-headers-"`uname -r`"

and if that doesn't work then check your sources.list and try again.

PS My name is Nick. I'm not that nice.... lol

Follow fix below

By the way, ignore the Linux header error in updating the kernel below. The apt-get - f autoremove will fix the error. Will also be included in the steps below.

Just waiting on post approval...

[xSk]

Sorry Nick, for that nice type.

It works I updated my sourcelist and load the headers.

I use ur Code and remove the "_" form line 621.

Thanks for ur work Nick ,

xSK

Follow new post below
Kernel 3.15 had bugs

3.16 fixed wifi and Internet drops.

[cjen1987]

Ok, there are still bugs with the rtl8723be on kernel 3.15.x.
SO DO NOT UPDATE TO 3.15,UPDATE TO 3.16 WHICH FIXES INTERNET AND CONNECTION

HOW TO DO SO BELOW:


I found the perfect fix with no disconnections or anything.

Same as above but use this instead:

1. For 32-bit system:

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa...31935_i386.deb

wget http://kernel.ubuntu.com/~kernel-ppa...031935_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa...31935_i386.deb

sudo dpkg -i linux-headers-3.16.0-*.deb linux-image-3.16.0-*.deb

2. For 64-bit system:

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa...1935_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa...031935_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa...1935_amd64.deb

sudo dpkg -i linux-headers-3.16.0-*.deb linux-image-3.16.0-*.deb


Choose 32-bit or 64-bit (depending on which system you installed)

reboot into the new 3.16.x

Run:

apt-get -f autoremove


Next run:

dpkg --list | grep linux-image

------------------------------------------------------
apt-get purge (Old Kernel):

apt-get purge linux-image-3.14-kali1-amd64
or
apt-get purge linux-image-3.14
-----------------------------------------------------------------



Once you removed old kernel run:


update-grub2





After you are done, reboot.
The wireless drivers will be 100% working and no data drops likein 3.15.x kernel!

[xSk]

I updated the kernel to 3.15, but now i cant load the driver, and i have the same problem before 3.15.

So i try to install the module but it dosent work, same Error! I try to fix it with nicks´s 622 line problem, but i cant install it, same error again.

Before 3.15 Kernel Update Wlan works but it allways drops the con. after a few minutes i cant reconnect.

The new steps above will update you to kernel 3.16 with the drop problem fixed. Fast connection also.



Just follow steps below, I spent hours trying to fix the problem myself, and have no more issues.

No need to edit anything or add a conf file, just update and go. Aircrack works fine too.

Installing an Ubuntu kernel on Kali is a sure way to break your system. Real bad advice.
