Choosing an Unmanaged Ethernet Switch: 5 Ports, 8 Ports or 2.5G?
An unmanaged Ethernet switch is a straightforward way to add wired connections when the LAN ports on a router are already in use. The useful choice is not simply “more ports”: count the devices that truly need wired access, check the speed of the network links you already have, and leave enough room for the next device. This guide focuses on ordinary wired-network expansion rather than a switch that requires network configuration.
Start by counting the wired devices, including the uplink
A switch uses one of its Ethernet ports to connect back to the router or existing network. That means a five-port switch normally leaves four ports for other devices when one port is used as the uplink. List the devices you intend to connect—such as a desktop, TV, printer, access point or NAS—and include the router connection in the count. If the list is already close to four connections, moving directly to an eight-port model can avoid an immediate second purchase.
The TP-Link TL-SG105S - TP Link TL-SG105S 5-Port 10/100/1000Mbps Desktop Switch and Grandstream GWN7700 5-Port Gigabit Unmanaged Switch 1GbE x5 are both listed as five-port Gigabit unmanaged switches. They are sensible products to compare when the number of attached devices is modest and the existing network is based on 1GbE. They should not be treated as providing five spare ports after installation: verify your own uplink plan first.
Match the switch speed to the slowest important link
Gigabit Ethernet (1GbE) is the relevant category when the router, connected devices and cabling are intended for that speed. A higher-speed switch does not make every connection faster on its own: the result depends on the ports at both ends of a link and the rest of the network path. Check the Ethernet capability of the router, computer, NAS or access point that matters most before choosing on speed alone.
The TP-Link card is titled “10/100/1000Mbps”, while the Grandstream GWN7700 is titled “1GbE x5”. These are exact title-stated descriptions, useful for identifying 1GbE options. For a situation with compatible multi-gig equipment, the Grandstream GWN7700M 6-Port 2.5G Unmanaged Switch 10G SFP+ x1 / 2.5 GbE x5 is listed as an unmanaged 2.5G switch with five 2.5GbE ports and one 10G SFP+ port. Confirm the exact interfaces on your own equipment before treating that extra speed or SFP+ port as usable in your setup.
Choose eight ports when the layout is likely to grow
Port count is often the easier decision to get right before cables are run. An eight-port switch can suit a desk cluster, media cabinet or small wired area where several devices are connected at once. It is also worth considering when an access point, a desktop, a storage device and entertainment equipment will share the same location. Leave practical space for the uplink and for additions you can reasonably foresee, rather than selecting only for today’s minimum.
The Grandstream GWN7701 8-Port Gigabit Unmanaged Switch - 1GbE x8 is listed as an eight-port Gigabit unmanaged switch with 1GbE x8. That makes it a clear comparison point against the five-port options. Its title confirms port count and speed class, not that it includes a particular cable, mounting method or other accessory; use the linked listing to check the product information relevant to your installation.
Keep the buying decision separate from the cable plan
An Ethernet switch needs a wired path back to the existing network. Before ordering, identify where the router or upstream switch is located, where the new switch will sit, and the length and routing of the required cable. The cable guide on KW Tech is a separate decision because cable length, connector access and the room layout still matter even after you have selected the right port count.
For an unmanaged switch, the main shopping questions are therefore simple: how many connections will be active, which speed can the important devices use, and whether a specialised port such as SFP+ is genuinely part of the plan. Avoid assuming that a product with a more technical title is automatically the better fit. A compact 1GbE switch may be the appropriate choice for an ordinary home-office extension; a multi-gig model is more relevant only when the connected hardware and uplink can make use of it.

A short pre-purchase checklist
- Count total ports. Include the one connection back to the router or upstream network.
- Check speed at both ends. Confirm whether the important links are 1GbE, 2.5GbE, or another interface.
- Identify the uplink. Make sure the chosen location can be connected to the existing network.
- Plan for reasonable growth. Choose additional ports when another wired device is likely soon.
- Read the exact listing. Confirm the model, SKU and physical requirements before completing the purchase.
Choose the switch around the network you can describe on paper, not a headline specification. A counted device list, a confirmed uplink and an honest speed check will lead to a more useful shortlist than comparing port numbers in isolation.
