cables, why not make use of the existing electrical wiring around the house? Most rooms have at least a wall socket - all you need to do is to plug in a Powerline adapter and you're good to go. These Powerline adapters come in different bandwidths and designs that does not only function as an Internet connection, you can also use it to transfer files and music across multiple PCs. The actual transfer rates depend on potential disruptions, where the most common performance figure would be 30Mbps when compared against the Ethernet's guaranteed 100Mbps or even a GigaBit Ethernet connection. Such speeds are sufficient for standard browsing, but those who look to transfer large files across the network or engage in network gaming sessions still swear by old school cables that are messy but reliable.
Pros : Easy to install, no messy wires to contend with
Cons : Not as fast and reliable as standard Ethernet
