Dear all,

I have an integrated realtek wifi card which seems to have very weak signal no
matter what i have tried. It could connect to wireless network, but it doesn't
have access to internet. My network card is specifically:

Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter

Kernel: Linux linux-sjtp 4.8.14-1-default #1 SMP PREEMPT Mon Dec 12 07:58:11
UTC 2016 (ab53e9a) x86_64 x86_64 x86_64 GNU/Linux

I figure out to find a workaround by following these steps:

1) Clone git repository with drivers:

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

2) Build and install them all:

sudo make install

3) Remove old module:

sudo modprobe -r rtl8723be

4) Add the new one with the antenna option:

sudo modprobe rtl8723be ant_sel=2

5) Keep the settings permanent:

sudo echo options rtl8723be ant_sel=2 > /etc/modprobe.d/rtl8723be.conf

Did anyone encounter something like this? Did anyone find a solution better
than this? Thank you!
