My Wifi 'extension cable'

There’s something deeply unfair about having perfectly good Wi-Fi but a wired-only device staring back at you like it’s 2006. That’s where the $40 TP-Link AC750 Wireless Portable Nano Travel Router (TL-WR902AC) swoops in like a pocket-sized hero. This thing is absurdly small—about the size of a deck of cards—but somehow manages to solve problems that would otherwise involve sketchy USB adapters, driver hunting, or just giving up. It’s designed for travel, sure, but it’s also perfect for those random “why does this only have Ethernet?” moments.

The real magic for me was using it in client mode. In this configuration, the AC750 connects to an existing Wi-Fi network and then shares that connection out through its Ethernet port.

Translation: your wired-only device suddenly thinks it’s on a wired network. No OS tweaks, no weird hacks—just plug in an Ethernet cable and go. I used it to give a stubborn wired device internet access over my Wi-Fi, and it worked so smoothly it almost felt suspicious. its also a great companion for test tools that only have ethernet ports for admin or out of band access.

Setup is refreshingly painless. You power it up (USB-powered, because of course it is), connect to it, pick your Wi-Fi network, and boom—you’re done. The web interface is simple enough that you don’t need a networking certification or three cups of coffee to understand it. Once configured, it just sits there quietly doing its job, like the best kind of networking gear: the kind you forget about because nothing is broken.

The best part? This little router is cheap, portable, and endlessly useful. Toss it in a laptop bag and suddenly you’re ready for hotels, labs, job sites, or any situation where Wi-Fi and Ethernet refuse to cooperate with each other. The TP-Link AC750 is basically a Wi-Fi interpreter for wired devices, and it does it without drama. For something so small, it delivers a surprisingly big “why didn’t I buy this sooner?” moment.
