Getting Engin 121 Voice Box to work with a D Link DI-524UP wireless router

After about a week or so of having my Engin installed, I noticed that it dropped out every few hours and needed a power reset to reconnect. If I repowered the D-Link router the engin ready light would come back on after a minute or two.

I suspect it was a problem in the D-Link router rather than the engin box. What I have done is make the Engin box the primary gateway to the Internet, rather than the D-Link router. This is not the recommended method but so far it seems to work. What this means is I have two routers between my PCs and the big bad Internet.

Connectivity is as follows:

1. Optus Cable Internet (connected by Ethernet port on the Motorola Surfboard SB5100 Cable Modem to the modem port on the Engine Box )

2. Ethernet port on Engin box to WAN port on D-Link DI-524UP .

In setting up the D Link DI-524UP I pretended that the Engin box was the Internet Router rather than a router in between. Here’s some screenshots of the D-Link router config and the DHCP screen from the Engin router. Make sure you find out these DNS settings or your D-Link router won’t know where to get DNS records.

If it’s Optus Cable, use the ones in the screenshot below. The process is:

1. Give the D-Link router a fixed IP address of 10.0.0.1 and make the Engin box the gateway for the D-Link router (10.0.0.99)

2. Set up the D-Link router to be a DHCP server and allocate IP addresses to the devices on the LAN side of the D-Link router. I use the default 192.168.0.1 address.
