Cable or DSL?

Cable

quote:

---

Every device in the house is wireless other than one PC.

All that means is that those devices will have a slower connection than your PC will. If your wireless router is rated faster than your DSL connection then you may not notice any problem though.

But if you are on DSL your gaming experience may be a bit lacking, trying to stream to multiple devices simultaneously from a connection source that isn't that fast to start with.
