If you could tell us how your network is connected, that would help.
How is your Aeon connected to your network? Ethernet cable to a router/switch?
How is your Mac connected to your network? Via wifi to your ethernet router/AP?
What are your Mac wireless settings? Take a snapshot of the System Preferences window, like this:
Your Aeon has a simple network setup - usually just ethernet IP address and a netmask.
In the case above, with your wireless in the 192.168.1.x range, your setting at the Aeon would be 192.168.1.x net mask 255.255.255.0
You may have a conflict with another IP address. Use LanScan (available from the Apple Store for free) to check all the IP addresses on your network and set your Aeon to an unused one. If you know the DHCP range your router gives out, it will help. You can find that by getting into your router firmware page, but not absolutely necessary.
Rudia networking is bulletproof, and Lightburn over ethernet has been proven to be very reliable.
If you have your networking set up correctly, and you still can’t connect to the Aeon, I would definitely think that you have an IP address conflict. LanScan will highlight that. LanScan on the Mac App Store
