If you want to add multiple devices to your network, I suggest to use Switch instead of HUB, switches have been invented to resolve many problems caused by HUB like "one single big collision domain, one big broadcast domain, speed limitation and so on". even with Switch sometimes it is necessary to create smaller broadcast domain wich is good for network performance by using vlan. so avoid using hub in your network if you can afford switch.
