I'm going wireless on a new laptop, in addition to DSL on home "Business HP"
desk top computer. Not sure how it interfaces with my DSL (same company),
though.
Is there anything I need to consider, or watch out for in re my XP Pro?
Your question is very strange, so I assume that you don't clearly
understand the issue you're asking about.
DSL is not on your desktop computer. DSL is the service that is
provided by your ISP (presumably your telephone company).
DSL comes into your home on a telephone line, and presumably goes to a
router. The router then provides the internet service it got from the
DSL telephone line to all your computers (desktops and laptops).
The way the router can communicate with your computers depends on the
router and the computers. You presumably should have a router that
provides both a CAT5 ethernet cable connection (to your desktop, or
desktops if there is more than one) and a wireless connection (to your
laptop, or laptops if there is more than one). Do you have such a
router?
So the "in addition to" part of your first sentence should be
"wireless in addition to ethernet," not "wireless in addition to DSL."
