Installing the modem is easy, getting it to work correctly may not be.

The modem should be pre-configured so all you have to do is plug it into the wall socket, connect the 75ohm TV cable, and connect a cat5 cable from the modem to your network card.

Getting it to work correctly really depends on the quality of your signal. If you have to many splitters, combiners, or other devices on your cable, it can degrade or block the signal to where the modem won't work or will experience dropouts. It's also possible to have too strong a signal and overpower the modem, which can cause dropouts.

Other than that, you might have to call tech support once and give them the MAC address off the sticker on the modem for them to activate it.

I can't give a realistic scale on the simplicity, because it may be easy (1) or may be difficult (5) depending on your circumstances.

i only intend to run a splitter for cable tv and my cable modem

also will having a few more computers in the house degrade the signal to my computer???

Depends also on how you connect them.
A router would be your best choice to add more PCs in my opinion.
