I'm trying to install Ubuntu 18.0.4 on a PC that had windows 10 on it a couple days ago (currently it has a broken, half installed Ubuntu). When I try to install Ubuntu, the step for connecting to internet doesn't have any options to actually do so. The only "network" it shows me is Realtek Semiconductor Co., Ltd., which isn't a real network. If I choose "try before installing," it still doesn't connect to the internet, and it freezes if I try to access my settings.
Specs:
The PC is a Lenovo Legion-Y7000P laptop.
CPU: i5 8300H
GPU: usually it just uses the built-in graphics on the CPU, but it also has a GTX 1050 ti
