I have freshly installed ubuntu 18.04.1 LTS. My usb wifi adapter which works perfetcly fine in windows 10 in the same system (dual boot), is not recognized here. the chip of the adapter is a Realtek 8811AU/8812AU.

I have gone through various posts here to identify but could not find anything to work. By going through different posts, i am providing the o/p of some commands before hand only.

I found the solution using this, https://medium.com/@at15/ubuntu-16-04-8811au-wireless-driver-d29d6929a50c

its just simple drivers download and installation for the specific chip which is Realtek 8811AU/8812AU
