I have currently set-up the following for wifi connection

My wpa_supplicant.conf file just had these two lines:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

And my config.txt file I did this:

auto lo

iface lo inet loopback
iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
   wpa-scan-ssid 1
   wpa-ap-scan 1
   wpa-key-mgmt WPA-PSK
   wpa-proto RSN WPA
   wpa-pairwise CCMP TKIP
   wpa-group CCMP TKIP
   wpa-ssid "My Secret SSID"
   wpa-psk "My SSID PSK"

iface default inet dhcp

The problem lies in the fact that the WiFi seems to disconnect after about an hour. I am using the raspery pi as a kiosk to connect to a website to display information.

Can I use the following below for this hidden network, link here?

Well, there is a very simple solution:

  1. Go to /etc/ifplugd/action.d/ and rename the ifupdown file to ifupdown.original
  2. Then do: cp /etc/wpa_supplicant/ifupdown.sh ./ifupdown
  3. Finally: sudo reboot

That's all. Test this by turning off/on your AP; you should see that your Raspberry Pi properly reconnects.

EDIT:

Can the above work fine with my custom config.txt file as when the raspery pi boots it gets an IP address from the router but I can not the wla0 in the Network GUI settings screen.

Add this to the bottom of your /etc/network/interfaces file, as it prevents power-save modes in the wifi dongles.
