As you know, there is no such thing as 100% secure anyways. None of these standard methods should make anyone feel like they are 100% protected. However, with each safeguard added, you definitely decrease your risk levels by significant amounts. I would venture to say that 95% of people with standardly secured wireless networks will NEVER have an issue.
I never said don’t run Wifi
I just said run WPA 2 with a unique SSID and a complex password is more then enough
Not advertising SSID does nothing for security and same with MAC filtering.
