Connecting to a wireless access point
This document describes how to set up a wireless network connection with WPA encryption.
First make sure your wireless drivers are loaded properly. (if you are using a Broadcom chipset, see note at the end of this post.)
Bring the link up so we can look for wireless networks. (An error here means you probably need extra drivers/firmware.)
Find a network to connect to. Look for the ESSID. In this example we will use the ESSID "MyNet".
Let's set the ESSID:
We need to create a shared key for wpa_supplicant.
It will wait for the password from stdin. Enter the password and enter. Now you will have a wpa.conf file with the preshared key.
Start wpa_supplicant with the generated config:
From another console, start dhcpcd:
You should get an IP address.
You then want to make the connection process automatic on boot-up. Open /etc/network/interfaces and add the following stanza:
auto wlan0 iface wlan0 inet dhcp
You will also need to set wpa_supplicant to start automatically on boot:
Next, create /etc/wpa_supplicant/ (permissions of 755 with root:root are fine), and move wpa.conf into that folder, renaming it to wpa_supplicant.conf.
Reboot and check that you are associated with the access point:
and check that you got a DHCP lease:
