Hallo Harvey,
if not something else is wrong with your installation or even
hardware, you should try some other ways:
1. Kick the Network-Manager from your disk and intall WICD
instead. Try, if it will work. Using WICD allone for controlling
both your network-interfaces, your "/etc/network/interfaces"
should be freed of all entries except the loopack entry. You can
configure wlan and eth0 with a right click on the symbol. Make
sure wicd has an autostart entry.
Additionally or alternatively you can try the way with "ifplugd".
Install it and edit "/etc/default/ifplugd" in that way that it
will controll the eth0 IF. You have to edit the
"/etc/network/interfaces" also and make an entry for eth0 just as
you already have, with stanzas like
"allow-hotplug"
iface eth0 inet dhcp"
Be sure that ifplugd has an autostart entry in the /etc/init.d.
If you remove the "-B" argument in "/etc/default/ifplugd" in the
"ARGS=" section, you should hear a beep each time ifplugd has
configured or deconfigured your eth0 IF. This should happen every
time you switch your LAN cable on or off your laptop. Doing this
you haven't to bother about your eth0 IF configuration any longer,
ifplugd should manage it.
To manage WLAN with ifplugd will, at least in my experience, work
only comfortably if you have an WLAN USB-stick which could be
hotplugged. If using the switch on the laptop it won't work by
me in the same way as it does with the eth0 IF. So I had to make
an entry for wlan in my "/etc/network/interfaces" too and use it
in the manual start-mode. I edit a
"/etc/wpa_supplicant/wpa_supplicant.conf" too, using the
"MANAGED" mode and if i want to turn it on I use a "ifup wlan0"
or a "wicd wlan0" - command as 'root' and it will start. My
"/etc/network/interfaces" has an entry for wlan like this.
#Wlan - Interface
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa-psk-tkip.conf
See and look if the one or other way will work, If not, there must be something
else wrong.
Greetings Dirk
