Note – I know nothing about Linux, just switched over from Windows. Also not an accomplished coder.
Installed Ubuntu 16.04 on a Dell laptop; it worked.
Installed it on an HP laptop (model 17 -x061nr) and the wi-fi will not work. In Network Settings, the option to turn Wireless on is present, but when I click it on it immediately switches back off again. I have no Ethernet ports available. I can download something on the Dell laptop and transfer it via flash drive, but that's it.
The HP's network controller is a RTL8723BE PCIe wireless network adapter, from Realtek. Prior to installing Ubuntu on this laptop, it was running Windows 10; the wi-fi worked there. The wireless isn't entirely kaput – the first time I switched it 'on,' the name of my wi-fi network appeared for half a second before the wireless switched off.
I've powercycled the laptop, reinstalled Ubuntu, and disabled, then re-enabled Networking. I looked in Software & Updates; it had one notification that the device is using an alternative driver (Processor microcode firmware for Intel CPUs from intel-microcode (open source)). I've tried enabling the wireless with and without using that device.
I've looked around the forums for similar issues, but haven't found anything quite like this.
Advice? Any further info required?
