More details are required:

Type of Internet connection device.

Are you really using a hub and not an Internet router?

Changing cables will do very little to help you. Cat5 vs. Cat6 is a
marketing gimmick, rather than a real technology improvement.

You'll have to give us more details about your network setup. Are you
assigning addresses via DHCP, or statically?
