For wireless...you can plug you computer (4 or them even) directly into the router AND you have wireless capability.
When these people mention securing the wireless...the router will broadcast the signal out so your neighbors could surf the web on your internet
There are 4 steps that resolve it.
SSID (service set identifier) = the network id basically. Say it's called MyNetwork. The router broadcast that out so your neighbor could see that
name. You turn SSID broadcast off. Unless someone knows the name...they can't connect.
Part two of this is to give the SSID a unique name from the default. Linksys default is Linksys (which many of my neighbors use). You change yours to
MyNetwork or BeerPub or whatever.
WEP (Wireless Encryption Protocol) = you can set the broadcast to encrypt the signal to various levels.
Finally, you can list in the router tools, which MACs (machine address codes) can access the internet. Unless that specific machine is listed, then no
dice. I have my machine, the kids, my laptop, wife's laptop, my playstation and my xbox in there for example. No other machines can access.
As for software firewalls, you will always have machine slowdown. I once read an article by a security expert that said with all the machines out
there, your chance of being specifically targeted is less than your chance of being stuck by lightning. Twice.
Anyway...hope some of that helps.
