Assuming the Express works like other wireless APs I've seen, the IP
address it has is irrelevant to whether the laptops can connect ... it's
essentially a layer-2 bridge.

And unless you've got a severely hacked DHCP server, the IP address
handed out to the Express should be the same every time (assuming it's
on the same network segment). It's part of the DHCP specification that a
device should retain an IP address over lease renewal.

Some ISPs operate 'DHCP' servers out of spec to avoid customers thinking
they own a particular IP address. Strictly speaking these aren't DHCP
servers at all.
