TP-Link LiteWave LS105G 5-Port 10/100/1000Mbps Desktop Network Switch

TP-Link 5-Port 10/100/1000Mbps Desktop Network Switch (LS105G) - 5 Years Local Warranty

The LS105G is a five-port Gigabit desktop switch from TP-Link's LiteWave Series. It is fanless, runs from a small 5 V adapter and needs no setup at all - plug it in, connect up to five wired devices and every port negotiates its own speed and duplex. For a Singapore home office, a shop counter or a meeting room that has run out of wall points, it is the cheapest honest way to turn one Ethernet socket into five.

Five Gigabit Ports, Auto-Negotiation and Auto-MDI/MDIX

All five RJ45 ports run at 10, 100 or 1000 Mbps and negotiate speed and duplex automatically, so a legacy printer at 100 Mbps and a NAS at Gigabit can share the same switch without any setting being changed. Auto-MDI/MDIX means straight-through and crossover cables both work, which removes the most common cause of a dead link when someone re-patches a desk. Supported standards are IEEE 802.3i, 802.3u, 802.3ab and 802.3x, plus IEEE 802.1p for priority tagging.

Fanless, Cool and Silent on the Desk

The LS105G has no fan. Maximum power consumption is 2.776 W measured at 220 V / 50 Hz and maximum heat dissipation is 9.466 BTU/h, so the unit stays cool enough to sit on a desk, behind a monitor or inside a shallow AV cabinet without ventilation. It measures 99.8 x 98 x 25 mm (3.9 x 3.9 x 1.0 in) and runs from an external 5 V DC / 0.6 A adapter supplied in the box. Front LEDs show system power and Link/Act per port, which is usually enough to diagnose a bad patch lead at a glance.

7.4 Mpps Forwarding, 2K MAC Table and 16 KB Jumbo Frames

Packet forwarding runs at 7.4 Mpps with a 2K MAC address table and 1 Mb of packet buffer memory, which is sized for a small wired cluster rather than a floor of endpoints. Jumbo frame support to 16 KB helps when the switch sits between a workstation and a NAS doing large sequential transfers. Transmission is store-and-forward, so each frame is validated before it is passed on and corrupted frames are dropped rather than propagated across the segment.

802.3x Flow Control, 802.1p/DSCP QoS and Green Technology

IEEE 802.3x flow control lets a congested port ask the sender to pause instead of silently discarding frames, which protects throughput when a Gigabit source feeds a slower device. 802.1p/DSCP QoS lets the switch honour priority markings already set by a VoIP phone or a router, so voice and video are not queued behind a bulk file copy. TP-Link's Green Technology trims power on ports with no link. None of this needs configuring - the switch is unmanaged and all three behaviours are always on.

Unmanaged by Design

There is no web interface, no console port and no VLAN, SNMP or port-mirroring support on the LS105G, and it cannot be adopted into an Omada controller. That is deliberate: there is no firmware to maintain and no configuration to lose. Where a site needs VLAN segmentation, PoE for cameras or access points, or central management, SourceIT can quote the equivalent Omada smart or managed switch instead.

Ideal For

Singapore homes, home offices, retail counters and meeting rooms that need to fan one Ethernet point out to a handful of wired devices - desktop PC, NAS, printer, console, set-top box or a wired access point.
