My desktop PC is about 10 meters away from the DSL modem. What's the better way to connect it, buy 10 m of ethernet cable, or buy a WLAN USB adapter? I have a 7 Mbps connection and play MMORPGs on occasion, so I'd like ping and latency to stay as short as possible. If I go with the cable, how important is it that it be a properly shielded, expensive one?
First, for the WLAN it is relevant to know if there are obstacles in the middle (mainly walls).
Anyway, I would go for the cable, 10m is not a long distance for CAT5e. Anyway, here is my reasoning:
Advantages of cable:
Advantages of WLAN:
Ethernet Cable will give you better latency and speeds. Since you're on a PC, I doubt you'll be moving around a lot. "Shielded cables (FTP/STP) are useful for environments where proximity or RF equipment, may introduce electromagnetic interference, and can also be used where eavesdropping likelihood should be minimized." Most ethernet cables are unshielded and rely on twisting. I'm not sure what you'll need shielded for. Even WLAN isn't interrupted too greatly by microwaves if you position your router correctly (and I doubt it's in between your PC and modem)
