We've heard your complaint and brought forth a new solution : the CASA Hub eC301, a wired Ethernet adapter with two "conventional" USB Type-A ports for your travel or office convenience. The two USB 3.1 ports allow your new laptop to hook up with the existing external devices such as printers, hubs, keyboards/mice or storage devices, so your current and future investment on peripherals are all in good hands.

Indeed, wireless networks are convenient, prevalent and almost indispensable, but there are still occasions that wired Ethernet is preferred. Wired networks are generally faster, more secure, stable and interference-proof, so you may want an Ethernet cable for the new laptop to take advantage of it when you're not on the road.
