Not necessarily true. It is initially set to be the default route and depending on the wireless router firmware, it may not be modifiable. > He says we should use it as a switch, only using the LAN ports, putting the > feed from upstream switches into one of those LAN ports. > Does this make sense? Somewhat, but not necessarily. Your definition of upstream is not automatically clear. Upstream normally corresponds to the direction of the default route. > In switches and hubs, all ports are numbered, none of them marked "uplink." > He says if port 1 is used as an uplink, the port next to it should be kept > vacant, > because it wont work. > True?

The switch doesn't give out IP addresses. The wireless router also has a DHCP server enabled to give out the IP addresses on its LAN segment. They probably don't have a DHCP server enabled on the upstream LAN segment, which is why your laptop wouldn't work plugged into that switch.
