Wifi Not Working in Lubuntu 19.10

I have an intel atom x5-z8350 wifi works perfectly with Lubuntu 18.04 but with the new Lubuntu 19.10 wifi does not appear and not working … could anyone help me?

Thanks for your post. In order to help further we will need some additional information. When you say WiFi does not appear do you mean the icon in the tray? Also if you could paste the output of lspci -nnk that would let us know which WiFi card you have and possibly which drivers you need.

Wifi card is integrated into atom x5 z8350

I was wondering if you can put the lubuntu 18.04 drivers and kernel in lubuntu 19.10

you can change the kernel, you can have more than 2 kernels installed and choose from which to boot with grub. Please, be comfortable using grub before installing a new kernel, since you could end up with some major problems and you would need to use another kernel.
Look here:

My friend, I already installed another kernel but it doesn’t work it seems that the files in this new lubuntu 19.10 kernel don’t use same lubuntu 18.04 kernel files … It’s not just a kernel install.

I was wondering how do I get the full 4.15.0.66 kernel from lubuntu 18.04 on lubuntu 19.10.
