hardwired is always preferred in my book and how I have my PC and PS3 setup (wired).
It provides the most stable connection and allowing maximum bandwidth; plus will not be subject to interference. However if you wish to have mobility (like a laptop) or the location of your router is in another room from your PC-setup wireless is fine as long as you can maintain a decent signal.
A lot of times people who cry about their wireless router dropping all the time is because it is suffering from interference like a 2.4GHz wireless router is in the same room or vicinity of a 2.4GHz cordless phone .. get DTECH cordless phones.. they wont' interfere with wireless routers.

Yes they can.. it is why I stay away from D-Link especially; Optimum Online has a habit of dropping on them or at least they "used to"
