If blocking the SSID, filtering the MAC address, and using the packet
encryption doesn't fully secure a wireless network from packet
sniffers, then what will? Just how many data packets have to be
analyzed before a smart cracker can penetrate the security of a
wireless network? If your basic home office user implements all of
the named security features above is there still a risk?

First of all, nothing is truly secure. Someone with a great deal of
time and persistence will enter your network. That is not to say that
you should be fearful. Unless you're some kind of VIP with prized
info on your network, it is unlikely that a person will devote that
kind of time to access your network or surf the internet at your
expense. There are too many "unsecured" networks around that are more
inviting. Then again, revenge is one hell of a motivator. Also, many
home users only share internet access and not files and printers. In
other words, continue to basically secure your network and practice
safe internet surfing and you will be fine. Take care.

The number of needed packets to analyse the key stream depends on the length
of the WEP key. For a 128bit about 2 mollion packets are needed.
If you are using WPA the key will change before an attacker can sniff enough
data.

Without WPA ot other security option the WLAN can be penetrated, but it will
need some time.
