Good price now (Cyber Monday) on this one, it’s popular and I see it recommended a lot:

GL.iNet GL-SFT1200 (Opal) Secure Travel WiFi Router – AC1200 Dual Band Gigabit Ethernet Wireless Internet | IPv6 USB 2.0 MU-MIMO DDR3 |128MB Ram

It has several modes, router is the regular mode. It can also receive your existing house Wi-Fi and repeater it, or generate wired ethernet output from It.

Tp-link makes something similar also.
