I've been receiving these notices lately (several in one day, like i was being bombarded). far from a techie but i did do some research on this. When I first received these notifications, I did the 'arp -a' in Windows powershell and did find duplicate physical addresses. I thought perhaps my wifi extender got compromised. I have since removed it about a week or so ago. I have since started to use my NordVPN on startup for my desktop. Previously, I just used my vpn when on ublic networks.
today, I received another series of ARP cache poisoning notifications (about 7 total). I was on my VPN, and I had already disconnected the wifi extender.
interestingly, it says this device accessed the network 1 day ago but it's been sitting on the floor for days.
Finally, I have a screenshot of my current results from Windows powershell. one when on wifi, the other when on ethernet.
any suggestions on what to do?
thank you in advance
