=ZTE MF823 Overview=
The ZTE MF823 is 4G dongle that (as of 2017) is widely available at a good price (Below £50).
Out of the box, it will work as an 'ethernet' device, and so the FireBrick or a computer will see it as a USB ethernet adapter. The Dongle runs a DHCP server and will dish out IP addresses to you in the 192.168.0.x range. Then, once its connected to the Internet on the 4G side, it will give you natted internet access.
A factory default FireBrick configuration will work with a ZTE MF823 dongle without any additional configuration
*The FireBrick will give you internet access over the dongle
=
The dongle will give internet access, and the FireBrick can also be configured to use the dongle as a backup internet connection if your main connection goes down. However, when used with a Data SIM from AAISP you may want to take advantage of the static IP and routed blocks of IPv4 addresses. In these cases you don't want the dongle to do any NAT. TO do this, the dongle needs to be configured to be a 'modem', and then we need to do a little bit of FireBrick config.
==Changing the ZTE MF823 to 'modem' mode=-
Warning: This is still in progress and does not work
AT+ZCDRUN=F
*Disconnect the modem from the computer and reconnect it to the FireBrick
==FireBrick config==
<dongle name="ZTE" vendor="19d2" product="0016" modeswitch="noswitch">
and change the <port...> item for USB to use usb="ZTE" rather than the default (which is usually Example-3G)
=Further help with the dongle=
===What mode is it in?===
