By manually configuring the antenna selection, you can force the Wi-Fi adapter to use a specific antenna that provides a stronger and more stable signal. In Linux, you can check and change the antenna configuration using the modinfo command and by creating a configuration file in the /etc/modprobe.d/ directory. The modinfo command displays information about a kernel module, including its parameters. By running modinfo rtl8723be, you can check if the ant_sel parameter is available for the RTL8723BE module. If the ant_sel parameter is present, you can use it to specify which antenna to use. The ant_sel parameter typically accepts values of 1 or 2, corresponding to the two antennas on the RTL8723BE. If the ant_sel parameter is not available, you may need to create a configuration file in the /etc/modprobe.d/ directory to set the antenna selection. The /etc/modprobe.d/ directory contains configuration files that are used to customize the behavior of kernel modules. To create a configuration file for the RTL8723BE, create a new file with a .conf extension, such as rtl8723be.conf. In the configuration file, add a line that sets the ant_sel parameter to the desired value. For example, to select antenna 1, add the line options rtl8723be ant_sel=1. To select antenna 2, add the line options rtl8723be ant_sel=2. After creating the configuration file, you need to reboot your system for the changes to take effect. After rebooting, the RTL8723BE will use the specified antenna for its wireless connection. You can then test the signal strength and performance to see if the change has improved your Wi-Fi experience. If you're still experiencing issues, try switching to the other antenna to see if that makes a difference. Remember to reboot your system after each change to ensure that the new antenna configuration is applied correctly.
