You do indeed.

Yeah, as it should.  Switches and hubs are different from access
equipment like routers, firewalls, access points, PC's, etc.  To
connect like devices (i.e. a switch and a switch, or a router and a
firewall or a router and a PC, etc.) you need a crossover.

Your laptop has to be auto MDI/MDIX or connecting the AP to the laptop
wouldn't work either without a crossover cable.
