ESET PC impacting LAN

When my ESET4-enabled desktop logs on or off my LAN it disconnects other wireless laptops. I'm guessing it may be a DHCP issue.

The DHCP server issues IP addresses in range 1.136 to 1.139. The ESET PC is always given 1.137, I don't know why, could it be connected to the ESET ZONE? I see there is something called "Local Addresses" which says:

IP: 127.0.0.1; IP: 192.168.1.137

I cannot find much of an explanation for Local Addresses, I thought I'd add the other DHCP addresses here to see the effect but it seems I am unable to edit this zone.

Any help, either why the ESET PC is disconnecting wireless laptops from the LAN, or why it always gets DHCP 1.137, or how I might include other IP address in "Local Addresses"?

Thanks
Tony

 

It always gets that address because it's dhcp lease hasn't expired, that's the way DHCP works. This sounds more like a router issue than an eset issue tbh.
