Yes, but if you login to the web portal, all of your devices are there but shown as, "not connected." Wouldn't it be easier for the customer to re-activate the device from the web portal? I didn't disconnect the device - ESET did.

Why fix what wasn't broken? Prior to the "update" all my devices were visible there with their corresponding license. Now I have to wrestle the devices from my family and re-register them. Why?

Thanks itman and The Pit. The network consists of a Netgear R7000 router and a Netgear EX7000 mesh extender running both a 2.4 and 5G network with one wired desktop which never duplicated) and 15 devices. Here's the solution: 1 Shut off the extender 2 Log into the router and reserve a block of address for static IPs. In my case 192.168.1.2 - .50. Anything on the network will then be bumped to 192.168.1.51+ 3. If a device can operate on both 2.4 and 5G, chose one and forget the other or you will have to repeat steps 4. Assign static IP addresses for each device. 5 If you really want or need to have both 2.4 and 5G on a device you will have to add another static IP for the other network as The Pit pointed out, MAC randomization creates a new MAC address for each network a devices connects to (one for 2.4 and another for 5G) 6. Reboot the modem, turn on the extender To keep things simple, we kept all devices on 2.4, allowing the extender to sit alone on the 5G network. Everything works perfectly now, both on the Netgear app, and ESET's Connected Home Monitor. Thanks again

Device Control is not enabled. It was installed as an extender, not an access point as cabling would be a problem. I installed the Netgear app on my mobile device. Even their app will show duplicates occasionally, but then they disappear after a few minutes without leaving any history. I shut off the extender and router, and ran the following at the command prompt as administrator as a Hail Mary: ipconfig /flushdns ipconfig /renew netsh winsock reset and then rebooted the computer. I then powered the extender and router back on. So far today I've had a couple of new devices detected (even though they weren't new) but no ARP warnings. As even Netgear's app can't get it 100%, I can't blame ESET. The stability and strength of the modem are amazing - I guess the extender and router hold on a bit longer than most to ensure transition. I can live with the occasional blue New Device Detected pop-ups. Thanks for your help.

Only devices that move through the house duplicate. The router, extender, printer, Chromcast haven't duplicated. A New Device alert just happened now. Glen's mobile was in the inner circle, but got bumped with a duplicate. Both devices are 192.168.1.10, but note that only one displays that and the MAC addresses are different.

The notifications are more frequently the blue box New Device Detected, but they are duplicates of existing devices. Log attached. Thanks. eis_logs.zip

I'll post it when I get back home this evening. Thanks

Hi, I have a Netgear R7000 router https://www.netgear.com/home/wifi/routers/r7000/. Once I added an extender https://www.netgear.com/home/wifi/range-extenders/ex7000/ I keep getting ARP Cache Poisoning notifications. (both devises running the latest January 2021 firmware) Looking at the Connected Home tool, two instances of the device appear when the notification is given. I think what is happening is that Eset is mistakenly flagging a hand-off between the router and extender as a security issue. I went to Setup->Network Protection->Connected Networks->and changed the setting to Home or Office Network from the default Use Windows Setting. Still got the same notifications. I then went to Setup->Advanced Setup->Network protection->Firewall->Advanced->Zones and added 192.168.1.1-192.168.1.15 to cover my devises in the Addresses Exclude from IDS in the Firewall Zones box. No more notifications. Did I do the right thing? and is there a risk by adding the exclusion. Thanks.
