Arp spoofing defeater?

[Jskn]

Any way to beat arp spoofing?  My family has a disney circle and its just annoying that I cant use internet ever on my home network.

Are you trying to spoof something or stop someone from spoofing something?

Aside some very expensive appliances there isn't much that can be done to stop someone from spoofing another MAC address on a home network.

 

Edit:

What you can do if they are just trying to change their MAC to something that isn't known on the network then you can whitelist all clients connecting by MAC address.

You could setup a Linux box and script notifications to alert you when a Mac address changes

I changed my mac address to a random but the circle still knows its me.
