A sensible way to stretch a dual-band WiFi network into rooms the router misses, with AiMesh support for ASUS owners. Its single wired port limits it as a hub for wired gear.

Overview
A far bedroom or home office where the router signal fades is the place for this dual-band ASUS extender. It repeats the existing WiFi network, can take a wired backhaul through its Ethernet port, and joins an ASUS AiMesh setup as a mesh node.
Mesh support makes it worth a look: on an ASUS AiMesh network it works as a node, and with other routers it still runs as a plain extender. Only one wired port is listed, so a desk full of wired gear will need a separate switch.
Who it's for
Homes where a few rooms lose the signal get the most from it, especially with an ASUS router running AiMesh. Shoppers looking for a full router, or for a cluster of wired ports in the far room, should look elsewhere.
Pros and cons
- Joins ASUS AiMesh as a mesh node
- Works with other WiFi routers too
- Wired backhaul option via Ethernet
- Gigabit LAN port for a wired device
- Only one Ethernet port
- Coverage area in square feet not listed
- Real throughput varies with walls and traffic
- Repeats an existing network, needs a host router
Performance notes
Speed in the far room depends on how strong the router signal is where the extender is placed, since a wireless link has to carry traffic both ways. A wired Ethernet backhaul removes that hop and leaves the radios free for client devices. Building materials and network traffic also cut real throughput, as the listing itself notes.
