Simple wifi connection in Arch linux

Since we were able to rename our network interfaces, we still have access to the internet, but how? The simplest way I see is to do it through DHCP. Having as prior the information corresponding to the name of the Wi-Fi network that we have at home and the access password

We begin:

ip addr it will give us again the name that we have placed on our interface. In my case I put the incredible name of Wireless.

We proceed to raise the interface with the command sudo ip link set wifi up

This will bring up the interface.

We need to create a file in / etc called wpa_supplicant.conf.

sudo nano /etc/wpa_supplicant.conf  and we put the following code:

network = {ssid = "Network name" proto = RSN key_mgmt = WPA-PSK pairwise = CCMP TKIP group = CCMP TKIP psk = "network password"}

We press Control + or and then Ctrl + x to save and exit the editor respectively:

Once out of the editor we proceed to run wpa_supplicant as follows

sudo wpa_supplicant -B -i wifi -c /etc/wpa_supplicant.conf

We have to wait approximately 2 seconds after entering the previous command and with dhcp we can now access the ip's assigned by the dhcp server in the following way:

sudo dhcpcd wifi

This will end up giving us the access we need. Logically the easiest way to check it is to open a browser.

It should be noted that all the necessary programs already come with the arch linux installation so we do not need to install anything additional except for very specific cases of modules not supported by wpa_supplicant and that we must look for in the wiki of the module we have.

Another thing to note is that I have used wpa2 as encryption for the wifi connection so we need to check in our router that this encryption is available.

I hope you find it useful!
