I got a laptop (HP Smart Buy 255 G7). It shipped with Windows 10. The wifi works in Windows. I wanted to install Ubuntu, but wanted to test that everything works with a live USB first (18.04 LTS).
Other components look good (camera and mic and I'm connected using a wired connection). However, I would like to know that the wifi will work once I install. It looks like a driver issue.
Running sudo lshw -C network gives:

Questions:
Can I test that this will work with the live USB?
Should I bother, or just install and fix once it's installed?
