Wireless 101

Recommended Posts

I need some real basic knowledge about wireless stuff. I want to get a laptop at some point, maybe even before I go on vacation so I can take it with me instead of being offline for several days while we are traveling and having to use my sister in laws computer when we get there. But I don't know the first thing about how all this stuff works. What exactly is it I should be looking for when purchasing a new lap top, what kind of software or is it hardware that it should have? I see lots of places that offer free wi fi like at restaurants and places, but how do you get online at those? And what about at home? I currently have Century link high speed internet, and my computer is hooked directly to a modem. What do I need at home to have internet access without actually plugging the computer into the modem? It would be nice if I could sit on the couch and check my email while I was watching TV instead of having to jump up during the commercial breaks to go check it. What would really be nice is if I could get a connection all the way down to the kennel, so I could keep an eye on my email while I was working down there.

 

Any and all input is welcome. But do keep in mind I'm not very smart about all this stuff, so if you can, explain in simple terms even a dummy like me can comprehend.

When you are out looking for a laptop, you can get a cheap one that has an Intel Core i3 4th generation processor and at least 4GB RAM. Every laptop has wireless Internet capability (WiFi) so you can go into coffee shops for Internet access too. The coffee shops typically have a web page shown to you as soon as you connect to their network and try to access the Internet (Eg. type Google.com, but instead of Google you get shown their website). You then have to enter a coupon number or accept their terms of service to be able to use the Internet and then it starts working. At home, the technician would set up a wireless router for you to use your existing connection and would 'pair' the router with your laptop by entering a password on both (the passwords are optional). To useyour laptop at someone else's home, you would 'pair' the laptop with their wireless router by entering their password.
BTW, you ought to watch Person of Interest. They show you a good deal of what technology these days is like.
