LAN speed *very slow* - wireless <-> wired

Hi
I have the following setup:
A Mandrake 8.1 server/router connected to a cable modem through a 3Com NIC.
A second Netgear NIC feeds an internal LAN throughg a 4-port Netgear hub.
1 Pbook G3 (OSX 10.1) wired to the hub.
1 Airport BS bridging the wireless and wired network.
1 TiBook (OSX 10.1) connecting to the Airport.

Now my problem is transfer speeds from my wireless TiBook to either
wired machine and vice versa.
I just copied a 3Mb file from my TiBook to the Linux box and it took
about 10 minutes.
I copied the same file from my wired Pbook to the server and it took a
couple of seconds.

The relevant output of ifconfig on my TiBook is:
en1: flags=8863<UP,BROADCAST,b6,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.1.3 netmask 0xffffff00 broadcast 192.168.1.255
        ether 00:30:65:14:27:80
        media: autoselect status: active
        supported media: autoselect

The output of ifconfig on my wired Pbook:
en0: flags=8863<UP,BROADCAST,b6,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.1.4 netmask 0xffffff00 broadcast 192.168.1.255
        ether 00:05:02:f5:96:7e

        supported media: none autoselect 10baseT/UTP <half-duplex>
10baseT/UTP <full-duplex> 100baseTX <half-duplex> 100baseTX <ful
l-duplex>

and my Linux box:
eth0 Link encap:Ethernet HWaddr 00:50:DA:CF:B8:0C
          inet addr:66.65.21.121 Bcast:255.255.255.255 Mask:255.255.252.0

          RX bytes:18928264 (18.0 Mb) TX bytes:309786537 (295.4 Mb)
          Interrupt:5 Base address:0x240

Has anybody any ideas why wireless<->wired communication is so slow?
I'm assuming it's the Airport bridge - does anyone know how to fix this?
Thanks
Kev.
