I agree about the Linksys router. However, I suggest that wireless is the
only way to go unless you will always have your computer next to your cable
or dsl modem. Also, if security is a concern, meaning confidential client
data like I have in financial planning work, you may not want that on an
internet available computer, regardless of the security that is in
place. I keep all such on an external drive and connect it only when my
wireless card is in the off position.
But, I digress. Most of my computing is on a laptop, and having it bound to a wire would kind of defeat the point of having a laptop. For my purposes, a wireless router and a gain boost antenna, so I can take it outside, work wonderfully.
