Why is my LAN not gigabit?

I would have expected that connecting two gigabit network devices to the HP ProCurve gigabit switch in my new house network would result in a gigabit connection between those devices, but every device says it's only connected at 100Mbps. Why?

To clarify, the wired LAN "connection information" in both Windows and Ubuntu says that the connection speed is 100Mbps. The status lights on the switch itself confirm this.

PC with onboard gigabit wired LAN adapter
 -> CAT5e cable to wall socket
  -> 10 meters of CAT5e cable from wall socket to patch panel
   -> 24-port gigabit patch panel
    -> 1 meter CAT5e cable to switch
     -> 24-port gigabit switch (HP ProCurve)
      -> 1 meter CAT5e cable to 10/100Mbps DSL router

My understanding is that because I use a switch, the 10/100 router should not slow down the rest of the network. The connection between a gigabit network adapter and the gigabit switch should be gigabit anyway - right?
