ARP spoofing

Is there an easy way to stop an ARP spoofing intrusion?
I also find turning on VPN does not always allow me to connect to the internet, I often need to restart several time before VPN locks on?

If you have any supporting screenshots, please add them:

@r_leverett Please share with us a screenshot of what Norton is alerting you to. Here is how to post screenshots here on the forums:
-What is your OS and its version/build?
-What is your version of Norton installed?

Norton 360 delux

Ahh. Was your VPN active when that alert came or did Norton activate the VPN as a response to it? From what I read, that appears to be a false positive because, the IP shows a computer on your local network, not an attack from outside your network. To be 100% positive check your router settings and match the MAC address shown in your screenshot to a device listed in the ARP connections listing. If its not there then there is indeed something to look at further.

Using http://192.168.1.42 does not allow me to connect, but it does say this is typically a router. The VPN was not engaged when the warning appeared, hopefully this is a false positive, is there any way to remove the warning?

Router logins are usually at http://192.168.1.1 or http://192.168.0.1
