Netgear GS316EP switch LAN IP address question

Question

NETGEAR 16-Port PoE Gigabit Ethernet Plus Switch (GS316EP) Managed

Sorry if I selected the wrong "Location". I couldn't find a "Switches" section

I have two windows PCs connected to the switch. I'm running an application that requires they be on the same network. One is on 192.168.1.xx and the other is on 169.254.246.xxx. I want all ports of the switch to be on the 192.168.1.xxx. Is there a way to configure the switch so all ports are on 192.168.1.xxx?

Thank you in advance.

Physically, this is (hopefully) the same Ethernet.
&nbsp;
In case the device connected has (or had) no connection to the router with the DHCP server (or the PC is configured to run on a random MAC address) or the DHCP pool is exhausted and no more free LAB IP addresses for are available (eg. because the DHCP pool is to small), modern clients fall back to the ZeroConf IP address. Most consumer routers are dealing with these addresses.
&nbsp;
Nothing the switch can do against this, regardless of we're facing unmanaged, smart managed, or managed switches. You have to figure out what is causing this possibly temporary network segregation, or why your router is unable to assign valid subnet addresses by DHCP.

This is a re-post that was inadvertently placed in a different location.

I have a NETGEAR 16-Port PoE Gigabit Ethernet Plus Switch (GS316EP) Managed. It is connected to an AT&T Gateway (HUMA4812D96B)

I have two windows PCs connected to the switch. I'm running an application that requires they be on the same network. One of the PCs has the address 192.168.1.xx and the other has 169.254.246.xxx. I want all ports of the switch to be on the 192.168.1.xxx. Is there a way to configure the switch so all ports are on 192.168.1.xxx?

Thank you in advance.

Asuming the gateway is a NAT router, able to assign LAN IP addresses to all devices conneted to it's LAN port (nd the switch), it's the router assigning IP addresses by DHCP to all connected devies.
&nbsp;
&nbsp;&nbsp;169.254.246.* are zero conf (automatic addresses) for a system not having a DHCP server on the LAN, modern devices and compurers fall bak to these mode while not successfully connected during the boot. start-up ...

Thanks for your message.&nbsp;&nbsp;While this switch is considered a "business product" I am a simple home office user and I know just enough to be dangerous. I get what you are saying about the IP addresses being assigned by the AT&amp;T gateway/router and not the switch. Am I right to assume that IP addresses that begin with 192 and 169 are not technically on "the same network"? Does this mean the gateway is giving out IP addresses that are on different networks.&nbsp;&nbsp;Here is what I'm seeing in the Router/Gateway.&nbsp;This is the PC that always has a 192 address&nbsp;Here is the PC that sporadically gets assigned a 169 address. However, wouldn't you know when I just rebooted, it was assigned a 192. address.&nbsp;&nbsp;&nbsp;Here is the same PC-1 when I switch to wifi and always gets assigned a 192. addressAssuming all this is true, and it may be outside the scope of this community, but how to I get the router to only give out IP addresses on the same network?&nbsp;Thanks again.
