  • TypeUSB Wi-FI Adapter
  • Expands one port to two for simultaneous device use
  • Gigabit speeds up to 1000 Mbps on both connections
  • USB power cable included for reliable operation
  • Six LED indicators show active device status instantly
  • Works with Cat 5 through Cat 8 cables universally

Network expansion for two devices

This GCROWN splitter turns one RJ45 port into two active connections so two computers, TVs or set-top boxes can share a single wall outlet. Both female ports operate simultaneously at up to 1 000 Mbps across Cat 5 through Cat 8 cables. A USB power cable is required to run the internal switching logic. The adapter suits homes or small offices where an extra drop is impractical.

Passive cooling with LED status

The unit has no fan and draws modest power from the supplied USB lead, so it runs silently on a desk or behind a router. Six LEDs show link and activity for each port, letting you confirm at a glance which device is transmitting. No external power brick is needed beyond a standard USB-A socket on a router, charger or PC.

Upgrade from single-port wiring

If you currently swap a single patch cable between two machines, this splitter removes that hassle and keeps both devices online. It does not replace a managed switch, so networks that need VLANs, QoS or more than two ports should use a proper switch instead.

Questions about this item

How do I install the splitter and which step is often missed?

Connect one incoming Cat 5/5e/6/7/8 cable to the single RJ45 input, attach two outgoing cables to the dual female ports, then plug the USB power cable into a 5 V USB source — the step people skip is supplying USB power, without it the splitter will not pass traffic.

What maintenance or replacement will this splitter need later?

No scheduled maintenance is required; if a port LED stays dark despite a known-good cable, replace the unit — there are no user-serviceable parts inside.

What limit appears first under sustained 1000 Mbps use?

The aggregate throughput of the single upstream link caps total traffic at 1000 Mbps, so heavy simultaneous transfers on both ports will contend for that shared bandwidth.
