Disclaimer: This worked for me. It may not work for you. If you've been tinkering around with Linux, or any computers for that matter, long enough you probably already know this.
So today I installed Arch for the second time. The first time I forgot to set up all the wireless stuff during the installation, so when I rebooted and couldn't get onto the internet I gave up. Today, after many hours of Googling, I was finally able to get it to work.
This is actually my second time typing this because I got about 90% done with the first tutorial and then accidentally hit the back keyboard shortcut and everything was gone.
Anyways, I used the installation tutorial video here. Everything worked for me, but he forgot to get all the necessary stuff for wifi. So here's the easiest way I found to do it.
Note: If you're on a wired connection you don't need to use wifi-menu in step 2.
Note: You must have Arch already installed to your hdd.
Note: This only works if your wireless adapter works out of the box, or is already configured to work in Arch.
Note: Highlighted areas are the parts you type in.
- Boot into your installation media.
-
wifi-menu
and connect to your wifi. -
ping -c 3 google.com
to test your internets. -
mount /dev/sdb2 /mnt
. Mount the root directory of your Arch install.
Note: My root was sdb2. Yours may be different. -
pacman --root /mnt -S iw netctl dialog wpa_supplicant wireless_tools
. This gets all the necessary files for using wifi-menu in your Arch install.
Note: I'm not sure if wireless_tools is actually necessary or not, but it doesn't hurt to have it, so just do it. -
reboot
. - Remove installation media once computer has shut down, or don't, it doesn't really matter if your hdd is first in your boot priority. Or if you have a computer like mine then it always boots to the hard drive, regardless or your boot order, for whatever reason.
- Once Arch is booted up, login as root.
-
wifi-menu
and connect to your wifi.
Note: Your wifi should work now, but let's test it real quick. -
ping -c 3 google.com
to test your internets.
If all worked well you should now be able to acces wifi-menu and connect to the internet. You will have to rerun wifi-menu every time you restart your computer, but now you can resume setting up your Arch system. Yaaaaay.
