Getting "ARP Cache Poisoning attack" popping up from antivirus

[Dimey]

I recently installed an antivirus and have had a few popups claiming that the Wi-Fi extender provided by EE was sending malicious traffic. I made a post on the forums, and they said I should get in contact with EE or check that the extender was set up correctly. I've been told it could be something in regard to the DHCP and was wondering if it's an easy fix as I'm completely clueless on the situation

@Dimey  Some more clues would be useful.

Which  antivirus and on what device?

Also which broadband service do you have, and which routers and any extenders?

Why do you/someone think it is a DHCP issue?

ARP Cache Poisoning Attack - EE Router - The EE Community

Hi there

I'm using ESET home security premium on my PC and when checking the device it seemed to point out the EE's provided smart Wi-Fi pro extender was the device sending traffic (EE busiest home bundle).

The only devices I'm using are the one's provided by EE (Smart Hub Pro and Smart Wi-Fi Pro) and as for the reasoning I'm not too sure, they were just replying on the ESET forum, and they seemed to think it could be a misconfiguration of the extender but said to contact my ISP tech support and I thought I'd double-check on the forums.

I had the same this. If I have a extender and Ur device is connected to it, the device like computer will maybe detect it as a arp spoofing or arp cache poison it may be nothing as the WiFi extender is connected to the WiFi router but instead of the router sending u the info the extender does so the device may think it's arp spoofing. But I am not sure so do be assured if I'm right or wrong
