@SteveV Hi.
Did you enter only the name or did you also specify the IP and port. All parameters must be specified...
If the tablet has WiFi, you can connect via "Ethernet". Please see my other answer here:

True, "Ethernet" is usual terminology for internal wired connections. But in this case "Ethernet" means internal wireless connections. I think other (more technical) terminologies would be even more confusing for the user.
Best regards,
