After performing a minimum install, there are variety of hardware/driver problems. But the most critical issue of all, is the WiFi. At first, I cannot seem to find a GUI, since it’s not installed from the base and later I learn that it must be configured through the .conf file.

As a previous Windows user, this is very strange to me, so I went ahead to do some research, but it quickly fell short. I’ve looked at some examples from blogs and tried to modify mine according to their guidelines, but when I restart the service, there were no dhcp persistent lease database or bound to Here’s the /etc/network/interface,

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static

# Wireless Interface
auto wlan0
iface wlan0 inet dhcp
wpa-ssid “SSID”
wpa-key-mgmt WPA-PSK
wpa-group TKIP CCMP

Hardware information:
Qualcomm Atheros AR9285
Realtek PCIe GBE Family Controller

When I use the ethernet cable, it works, but does not indicate anything within Debian that internet access has been connected vice versa.
