Is it worth it?
The TP-Link Archer A54 is a sensible pick for a small home that needs dependable Wi-Fi without paying for features it will never use. Its appeal is straightforward: dual-band coverage, EasyMesh support, WPA3 security, and a simple setup path for everyday browsing, streaming, and light device loads. The main trade-off is just as clear, though. This is a Fast Ethernet router, so it fits best when your internet line and wired devices do not demand gigabit-class throughput.
Buy it if you want an inexpensive home router that is easy to live with, covers a modest space, and can be folded into a mesh later. Skip it if your priority is high-speed wired networking or a router that needs to anchor a more demanding multi-gig setup. For that kind of buyer, the four 10/100 Mbps ports are the limiting factor, not the Wi-Fi feature list.
