Unfortunately, reducing paranoia requires understanding. Having a program make decision for you is obviously easier, but it doesn't reduce worry. Besides, Network Magic doesn't support Linux.

Although a couple years old, you may want to read The ABCs of securing your wireless network. Also be sure to use a strong password for your wireless network. Set up a security key for a wireless network. Then, as Jonathan said, any hacker still has to get past the Windows logon. In Network and Sharing, limit any files being shared to public and require a password for access.

Curiously, your first link seems to discount the benefit of most settings, other than encryption method. Perhaps I'm making this harder than need be...don't know.
The ABC's link is a couple years old. I provided it for information.

This idea throws me somewhat, because I wanted to be able to access any file from either computer. Unless I misunderstand, sharing with the "public" includes other computers on the network...yes/no? I was hoping that within my network access would be simple, but with a hard shell to outside access.
No, not other computers on the network. I meant public folders -- placing music and videos in public folders, and making them accessible but not documents, thereby further protecting any confidential materials.

In fact, if you are only going to use the wireless connection "just for the purpose of giving my secondary computer access to streaming media from the internet," then you don't even need to provide access to the other files.

Disable DHCP

Switching DHCP off and using static IP addressing is no defense against hacking. Anyone snooping the network can usually figure out the pattern that has been used to assign the IP addresses in question and then make a specific request accordingly.
The ABCs of securing your wireless network
As I said earlier, it's we can't really make a network 100% secure...

Here's a thought. Here, you, a wifi snooper, sniffing wifi AP in a neighborhood. You found one, unsecured, connect to it... then connected. But when you check your IP, Windows (or whatever your OS) used APIPA addessing (the one that starts with 169.x.y.z) indicating no DHCP server. The first to try is 192.x.y.z network, see if it works, do a scan in the subnet. If nothing shows up, use 10.x.y.z, do another scan, etc... What I propose was for our TS to use, let's say, 180.99.99.x network, with 27 bits subnet (that is subnet mask). This will hinder the hacker's attempt to connect to the network.

In my more advanced suggestion (point 5) is like this:
LAN = 180.99.99.x/, gateway at, and use another DNS server, let's say we use and as DNS servers. That alone will slow the so called hacker down... Unless the hacker use packet sniffer and try to look for packets that are running around... But then again, if the WPA2 key is at least 32 characters long with random chars + symbols, it'll be A LOT harder do "crack". If you use dictionary attack, that attack will only work for words in the "dictionary", 32 random gibberish doesn't count as a "dictionary" word... After the hacker succeed, he then needs to scan the network for another host to connect to... This will be the VPN server, the open port is only the VPN server listen port... connecting to this will engage another authentication dialog. Set the VPN server to black list host that failed upon 3rd try... Once he can connect to the first VPN server, the hacker needs to do the process all over again to connect to the next VPN server... urgh... here's the simple "map":

[public IP]Router[]-->LAN(180.99.99.x/
Wifi Network honeypot 1, VPN server + Traffic filtering + SNORT server
Wifi Network honeypot 2, VPN server + Traffic filtering + SNORT server
Wifi Network honeypot 3, VPN server + Traffic filtering + SNORT server
Wifi Access point [ Static assigned IP address]
[The hacker starts here...]
