I just set up a wireless connection with my powerbook and a linksys router and want to find out if it is secure. I made my own SSID, disabled SSID broadcasting, set up the MAC filter, and am using 128 bit WEP protection. The thing that I am concerned about now is that Linksys and Default appear as network connections and I don't know how to delete them. When I use the Macstumbler software it detects them also. I cannot access these networks can anyone else? If they can I assume that they would be on a different network and unable to access my computer just use my bandwidth? Is there a way to delete them? Any feedback greatly appreciated!
