This article from MaximumPC is a how-to on securing your wirelessLAN. While I kind of agree that security and wireless LANs are oxymorons, you have to do what you can. So I've enabled WEP and MAC address filtering, but have not disabled SSID broadcasting.
As the article indicates:
Most access points, however, include an option to disable SSID broadcasting. It's generally a good setting to disable, but we have had some problems maintaining connectivity when using Windows built-in wireless configuration interface to connect to Wi-Fi LANs with SSID broadcasting disabled. And this problem is exacerbated if other people in your neighborhood have wireless LANs setup.
In my case, I'm not using Windows built-in wireless configuration interface but I'm still having intermittent problems with connections so I've left SSID enabled. I realize this makes things slightly less secure but what's a person to do? With SSID enabled I am always able to connect, with it disabled I get connected less than 50 percent of the time. Perhaps this is caused by other nearby wireless LANs, at least one of which my LAN can see.
But in any case, I've done all that I can do, including adding the wireless router downstream of the main LAN's router. Of course, there is one more thing I've done. I turn off the wireless router when I'm not using it. That gives me 100 percent security.[g]
