Connected to the AT&T Router connected to the Internet via both:
WiFi 5GHz
Cat5 cable directly to the router.

I see both at the tray window showing the connections available.

I am trying to see what the speed is for each.

How do I steer to the connection I want to test ?

What tests can I do ?

How deep do you want to go? What other equipment do you have available
that you can put into service? For example, if you have a spare router,
configure one of your interfaces with static routes to use it as its
gateway. Then, any traffic destined toward the destination of your
static route will use that interface. Or, if you have a spare PC,
configure one of your interfaces to prefer that connection to contact
the second PC.

What you're asking is pretty easy, but there are a lot of moving parts,
so some basic networking knowledge and a spare router or PC will be a
big help.
