1) Why does having a child affect whether or not you have 802.11 (wireless)? Are you afraid that the signals will cause cancer or electrosensitivity?
2) Coaxial cable has a data transfer rate of about 30 mbps per channel. Depending on how recent your computer, your router and your cabling are your Ethernet connection will either be 100 or 1000 BASE - that is, with a nominal transfer rate of 100 or 1000 mbps.
So, functionally, I doubt it makes much difference - your broadband connection is unlikely to be able to output enough data to max out either cable, unless you have business-grade cable Internet. If you want to experiment, go to speedtest.net and check your download/upload speed with both options, but I doubt any difference will be noticeable. If I were you, I'd probably put the modem wherever it is least obtrusive and easiest to connect to a power socket.
For reference, 802.11b (which I assume your powerbook has in its Airport card - if you mean Powerbook as the type of Apple laptop replaced by the Macbook and Macbook pro moments after I bought one rather than as a generic term for an Apple laptop) has a data transfer rate in ideal conditions of 11 mbps, so it's notionally slower than both types of cable, but over six feet and with a normal cable broadband connection and normal usage I doubt you'd notice. If your Powerbook is basically static, and you have no other devices, tethered or wireless are probably equally effective. |
