Rather than buying a stand alone wireless router....can
a person just configure his desktop with wireless card
to ACT as a wireless "router" and save some desk space
if short on space?
Are we to guess what operating system you intend to use on your desktop
(which you don't have yet despite claiming to be a poor student)?
What are your qualifications for consuming space for a desktop when your
only need is wifi access for your laptop?
You could use your desktop and its unidentified OS to run as a gateway
but you'll need 2 NICS: one for your intranet and one to the Internet.
Of course, now you'll up the cost of getting 2 NICs (one wifi and one
connected to your unidentified Internet service type) along with the
entire cost of a desktop when a wifi router would have been so much
cheaper.
Why are you getting the desktop (which you don't have yet)? Since it
will occupy space, why not get a wifi router that sits right atop the
desktop's case? If you have room for the desktop then it's likely you
have room for a router. If you're that tight, put the router under your
bed (but make sure it has breathing room to ventilate away the heated
air since routers don't have fans for cooling and rely on convection).
If you have a desk (on which the desktop will sit atop or underneath),
just get some self-stick velcro strips and stick the router on the side
of your desk or underneath on the privacy panel (in front of your feet).
