Name functions rather than box labels
A product sold as a router may offer access-point mode. A provider gateway may combine modem, routing, Wi-Fi, address allocation and other services. Write down which device currently supplies the internet connection, DHCP and wireless coverage before adding another box.
A familiar Wi-Fi name does not prove that two access points share one correctly configured local network. Separate routers can broadcast similar names while maintaining distinct subnets and policies. Check the actual topology rather than relying on the name alone.
Choose the role for the intended job
If the goal is extra wireless coverage within an existing network, a supported access-point arrangement may fit. If the goal is a deliberate separate routed network, a router role may be appropriate. The correct configuration depends on equipment and administrative requirements.
Do not connect ports according to an unrelated brand's diagram. Some modes use a particular uplink port and change management addresses. Follow the exact model's documentation and preserve a way to restore the original configuration.
Diagnose the right boundary
An illustrative television and phone can both browse the internet while local discovery fails because they sit on separate routed or isolated networks. That differs from both devices losing their upstream route. The role diagram helps the administrator choose the relevant test.
Adding an access point also does not automatically improve a slow provider connection. It can improve a local wireless path if coverage or contention is the limiting factor. A controlled same-device comparison is needed to establish the practical result.
Verify after a role change
Check address allocation, ordinary internet access and the original viewing or discovery feature. Confirm that optional provider services still work where they are part of the setup. Keep non-sensitive notes about the chosen mode and management route.
The network role does not change a subscription's simultaneous-stream allowance or make an unsupported player compatible. Preserve those separate requirements when assessing the overall setup.
A sharper comparison
Two devices receiving addresses from different local subnets should prompt a topology check, not an immediate reset. Confirm which box issued each assignment and whether separation is intentional. A guest or isolated network can correctly provide internet access while preventing local communication that a particular feature expects.

Is an access point the same as a Wi-Fi extender?
Not necessarily. Products can provide different uplink methods and modes. Identify the actual wired or wireless backhaul and configured role.
