I followed the Arch Linux installation video to a tee. Everything was great until it came to the installation of the optional CPU packages. I have Intel so I typed out the correct pacman command but it failed to find the repositories. I thought that was weird because everything up until this point was working perfectly. So I did what everyone does and I tried it again, same result. I then decided to check my internet status by pinging Google and it did not work like it did previously in the tutorial video. I then checked on my network adaptors and to my surprise the wlan0 I had used this whole time was not listed, along with my ethernet(which I was not using but was there previously).
I did the classic reboot to see if it fixes the issue but alas it did not.
I am here to ask for help on what I can do to resolve the issue. If I need to start the installation process again at what point should I start from and in general just find out what happened so I know for future reference.
In case you need to know I am very new to Linux in general only dabbling with self installers in the past and I thought I would give this a go. I am not frustrated just want to learn from any mistakes I have made.
Any help will be greatly appreciated or questions I need to answer will be promptly replied to(as long as I am awake that is).
Thank you for taking the time to read this novel.
