I have a HP ac123tx laptop. A few days ago I installed Ubuntu 16.04. I don't know much about Linux but I want to learn. But the Wifi is not connecting. It seems some driver is missing, I tried to install but it did not work.

My network card details:

07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller (rev 07)
13:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter

seems to be a known issue, trying to edit this file (first make a backup of it)

/etc/modprobe.d/rtl8723be.conf 

add the following text:

options rtl8723be fwlps=N ips=N 

did this reboot
