Compatibility is broad: it works with Cat5, Cat5e, Cat6, Cat7, and Cat8 cabling and connects to routers, switches, hubs, smart TVs, and wireless access points. Setup is genuinely plug and play, with an included 80cm (2.6ft) USB power cable…

SpecPicks Verdict

SpecPicks scored LIEZHUA Upgrade Ethernet Splitter 1 to 3 High Speed 1000Mbps using a rating × review-volume × price-fit model applied to published specs and reviews across the retro networking cards category. LIEZHUA's retro networking cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for retro networking cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent.

Frequently Asked Questions

Can all three ports be used at the same time?

Yes. LIEZHUA specifies simultaneous networking for three devices, so all three RJ45 outputs stay live at once rather than switching between them.

Does this need to be plugged into power?

Yes. It is powered by the included 80cm (2.6ft) USB cable, so you need a free USB port or USB wall adapter nearby. It is not a passive splitter.

What cable types does it support?

It supports Cat5, Cat5e, Cat6, Cat7, and Cat8 Ethernet cable. Note that no LAN cable is included in the box, so bring your own patch cables.

Will it slow down my internet speed?

It is rated at 1000Mbps. Keep in mind the three devices share the single upstream connection feeding the splitter, so your total bandwidth is still capped by that line.

What devices can I connect it to?

LIEZHUA lists routers, switches, hubs, TVs, and wireless devices as compatible, which covers most desktop, console, and smart-TV setups on a wired drop.
