Switch selection and setup

Five-port vs eight-port switch: count the uplink before buying

The connection back to the router normally consumes one of the switch’s advertised ports.

Switch selection and setup

Managed vs unmanaged switches for a home network: which controls will you use?

Choose management for a defined requirement such as VLANs or port diagnostics, and plan who will maintain it.

Switch selection and setup

Do not add a second switch uplink as an automatic speed boost

Parallel Ethernet cables require a supported topology; otherwise they can create a loop and disrupt the LAN.

Switch selection and setup

A guest SSID with a VLAN needs a complete path through the switch and router

Naming a wireless network “Guest” is only the first step; verify tagging, addressing and access rules end to end.

IGMP snooping and IPTV: when a switch setting deserves investigation

Confirm that the service uses multicast before treating IGMP snooping as a universal streaming fix.

TL-SG105-M2 vs NETGEAR MS105: a practical five-port 2.5G switch checklist

These unmanaged switches serve a similar role; choose from connection needs, placement, support and local availability.

A 2.5G switch with a Gigabit uplink: what gets faster and what stays shared

Local device-to-device transfers and traffic leaving the switch do not necessarily follow the same capacity limit.

Switch port isolation vs VLANs: understand what each boundary controls

Port-to-port forwarding restrictions and logical network membership are different controls that require their own tests.

What can a 2.5G switch improve when its uplink is only Gigabit?

A 2.5 Gigabit switch connected to a Gigabit router can still provide a useful local upgrade. The key is to distinguish traffic that stays between devices on the switch from traffic that must cross the router uplink. A capable workstation transferring to a capable storage server on the same switch may use their faster local connections. A download from the internet must also cross the router-facing link and the broadband service. Those are different paths with different constraints.

How can I confirm that mesh Ethernet backhaul is active?

An Ethernet light blinking on a mesh node does not by itself prove that the node is using that cable for backhaul. The port could serve a client, negotiate at an unexpected rate or connect to an unsuitable network segment. Identify both endpoints and any intervening switch or wall patch. Check that the arrangement matches the mesh system's active operating mode. Label the path if several similar cables share a cabinet.

What should a UPS power to keep an internet connection working?

A battery backup for the router is useful only if the other devices needed for connectivity also remain powered. For fiber service, that may include an ONT, a switch and the access point used by the household. Draw the route from the provider handoff to the device that must stay online. Identify each powered component and its location. A remote mesh node on another circuit may stop working even while the main router continues running.

Should I power one access point with an injector or a PoE switch?

A standalone PoE injector can add power to one Ethernet path without replacing a working non-PoE switch. A PoE switch combines multiple data and power connections. Choose between them based on the installation you expect to maintain. For one access point, an injector may be a simple addition. For several access points and cameras, separate injectors create more power adapters and cables to organize. Include likely near-term additions rather than counting only today's first device.
