The setup looks like this: BT Smart Hub connected via Ethernet, powered by a switch with an Ethernet cable, then extended wirelessly using a range extender. Other wired devices are present on the switch, and DHCP is enabled there. The smart hub supports DHCP. You’re unsure about the switch’s configuration—check later. For now, you’re deciding whether to enable DCHP on the switch or not. If you need DHCP for the switch, let me know.

Only one DHCP server per network is recommended* *there are exceptions, but they aren't something to be concerned about*

Certainly! Let me clarify that for you.

It might cause several devices to share the same IP and then problems arise. However, DHCP reduces this risk by checking for existing addresses before assigning them.

Alright, I understand. Let's get started.

I checked the Switch and DHCP Mode; it was powered on. I turned it off. Note: Just upgraded the firmware to the latest version. BT Smarthub I need to confirm the BT Hub supports DHCP, which should assign dynamic IP addresses. Here’s the relevant settings page from the BT Hub. Could you check if the DHCP Server is enabled by reviewing the screenshots? Thanks, Edimax Wireless (Wired) Range Extender.

It works fine. Your BT Hub router supports DHCP. Running multiple DHCP servers on the same subnet often leads to problems since devices can't determine which one to contact, resulting in conflicts and network issues.

In a Switch DHCP setup, the device requesting an IP typically acts as a DHCP client, while a range extender functions as both a server and a client. You’d set the server off and keep it active for clients.

It varies by setup. For a simple consumer switch, it won't work. A managed L2 switch probably lacks a DHCP server. Most Layer 3 switches include DHCP functionality.

It's crucial to distinguish between DHCP Client and DHCP Server. You shouldn't disable the Client unless you're certain the assigned IP won't conflict with the router's DHCP range.
