Wifi weak signal with realtek d723

[andresgaibor]

I am new to Linux, I installed the drivers for the graphics card (Realtek d723), it works, but I am literally sitting next to the router and I have a -78dBm signal, I don't know what to do, I have already seen in a lot of forums but nothing solves my trouble. I don't know what information you need, if you need anything let me know

[jeremy31]

What site did you get the driver from?

[andresgaibor]

I used this

git clone -b extended --single-branch https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add rtlwifi_new
sudo dkms install rtlwifi-new/0.6

[jeremy31]

Did you set the ant_sel parameter? Most of the time it works best if set to 2

[andresgaibor]

Yes, but it doesn't work for me

sudo modprobe rtl8723be ant_sel=(1/2)

[jeremy31]

Post results from terminal for

grep [[:alnum:]] /etc/modprobe.d/*

It worked, thank you very much

For reference you can read up about it in an arch linux post: https://bbs.archlinux.org/viewtopic.php?id=208472

I stumbled on this post after I already followed the arch wiki. It turned out I had to use the second antena. These where my steps:

# As the article is somewhat Arch Linux specific I had to do tiny adaptations for ubuntu 20.04

# edit / create the following file:
/etc/modprobe.d/rtl8723be.conf
==============================
options rtl8723be fwlps=N ips=N swlps=N swenc=Y disable_watchdog=1

git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
#git checkout rock.new_btcoex --> this isn't working so checkout the following as stated in the error message:
git checkout origin/extended -b extended

make clean && make
sudo make install

# sudo mkinitcpio -p linux
# ubuntu version to update initramfs:
update-initramfs -u


# After every kernel update:
cd rtlwifi_new
# Clean previous builds
make clean
# Update git repository
git pull
# Compile
make clean && make
# Install
sudo make install
# Update initramfs
update-initramfs -u


#Test which antenna works best for you:
sudo rmmod rtl8723be
sudo modprobe rtl8723be ant_sel=1
sudo iwlist wlan0 scan
sudo rmmod rtl8723be
sudo modprobe rtl8723be ant_sel=2
sudo iwlist wlan0 scan

# then
