how to gwet a internet connection on a downstairs computer with either modem or router?

[WO LEE]

if you intend to have a wireless connection , you need to have a desktop/laptop WI - FI capable if not a hard wired connection. the rest is a simple LAN software set up; naming each computer a specific network name, then edit the "share" option of every device available in the network ( printer, storage etc..)...

Recent Operating systems ( windows and the like) made it very easy to create a shared network..

Yes You need a router to share interconnected resources Plus the modem to share Internet connection.

When you buy a router ( Wireless or Hardwired alike) you get the direction how to set up... make sure to use a keyed connection ( password) as many ROUTER first time users overlook the importance of a secured connection allowing strangers leech on your connection and possibly maliciously breach your privacy.



Good luck.
