Hi all.. I'm using HP ProBook with Kubuntu 14.04 but my WiFi keep dropping connection. I have to reboot laptop to connect WiFi again. I use this command to fix my WiFi problem and it's working fine. echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf Anyway my chipset is Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter. This setting can be different depens on your chipset. To see your chipset, you can use this command. lspci I hope this can usefull for you to!
