[SOLVED] RTL8723BE Lenovo G50-70

jobalcaen · 02-09-2015, 08:52 PM

Hello everyone,

I recently finished installing Scientific Linux 6.6 on my newly purchased Lenovo G50-70. I'm unable to get the wifi working

lspci reveals the following:

Code:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter

I googled the wifi card model number and I came upon this page:

http://unix.stackexchange.com/questi...n-ubuntu-14-04

I tried git cloning this repo: https://github.com/lwfinger/rtlwifi_new and installing the gcc and kernel-devel packages but when I attempt to make I receive this:

Code:

[jobalcaen@kimura rtlwifi_new]$ make
make -C /lib/modules/2.6.32-504.8.1.el6.x86_64/build M=/home/jobalcaen/git/rtlwifi_new modules

make[1]: Leaving directory `/usr/src/kernels/2.6.32-504.8.1.el6.x86_64'
make: *** [all] Error 2

My kernel version:

Code:

Linux kimura 2.6.32-504.8.1.el6.x86_64 #1 SMP Tue Jan 27 13:39:10 CST 2015 x86_64 x86_64 x86_64 GNU/Linux

I've also read that I might need to use backports, but my attempts at installing backports have failed.

I'm not sure where to go from here and would appreciate any help.

Thanks,
Joel

I did some searching and found out that the driver for the RTL8723BE is in the 3.15 Linux kernel.
Often times installing a newer version of the kernel helps hardware issue's most of the time.

These links are a start:
The rtl8723be module is included in the mainline Linux kernel since version 3.15.
https://wiki.archlinux.org/index.php...tion#rtl8723be

This link might help too.

I looked on the Realtek website and I couldn't find a driver for your card; sorry.

HTH

Not sure why adding the repo isn't working for you.
Some repo's are disabled by default to prevent a certain things for some reason. So it may be that it has to be enabled.(the backport that you mean)

Did you try adding it to the /etc/yum.conf file?

Maybe another member running Scientific Linux will chime in and help.
Sorry I don't know more.

Thanks for the help. I fixed it by installing Ubuntu 14.04 LTS which supported the card right out of the box.

Your Welcome. Glad your laptop is working.

It's nice to have a distro that works out of the box with your pc's architecture.-
