cyril7: Ahhh, I would remove the DHCP server on the wireless, othewise the clients will be given the wrong gateway and fall over. As an experiment purhaps, set one of the wireless clients on static IP 10.1.1.30 for now with the gateway 10.1.1.1, does it see all.
Thanks
The one wireless client is already on a static IP. So I don't hink that's the magic bullet I'm looking for :-) (I have disabled the DHCP though)
