Thanks gazza, your explanation sounds simple and easy to accomplish. If I follow your suggestions and assign the IP addresses to the 3 computers, (2 laptops and 1 desktop) so that they are constant, would the router then assign the next available address to the Ipad when it is connected to the network?
Thanks again for your response

Addresses you assign manually (static) are not taken into account by the automatic address hander outer (DHCP server).

Therefore, each DHCP server (address hander outer) has a range of IP addresses that it pulls from (usually .2 - .150). Any static / manually configured addresses should fall outside that range.

Every router I have bought allows you to manually set the IP address range you can dynamically allocate through the DHCP server. I have set my routers to allocate in 192.168.1.101 to 192.168.1.200. This allows me to allocate Static addresses in the 192.168.1.2 to 192.168.1.100 range for connected devices - printers, PCs, servers, routers, bridges and media units. If you set your router up with this type of setup then other users can attach using dynamic IP addresses including Ipad users. Also some routers allow you to manually set permanent IP addresses to MAC addresses in the router table. This may be a little more difficult for some users as you need to find MAC address of the Network Interface Card (NIC / LAN card).

Theoretically you can connect 253 devices to your router but the network would run very slow. Ther are 256 IP addresses in range of 192.168.1.0 to 192.168.1.255 but three of these are normally reserved:-
192.168.1.0 is network address
192.168.1.1 is router/gateway address
192.168.1.255 is network broadcast address
This is of course assumes you use a Subnet Mask of 255.255.255.0
