If you simply want to connect 2 devices, the best data rate will probably be obtained by connecting the 2 systems directly to each other, thus avoiding the complexity and possible degradation of service introduced by having a third device involved.

If the hardware platform on which you are running Ubuntu has a Gigabit Ethernet wired network interface, use that.

Alternatively, configure one of the devices as a WiFi access point and configure the other as a WiFi client.
