Like signals from your cellular or cordless phones, signals
rom
our wireless network can also be intercepted. Since
you cannot physically prevent someone
rom connecting
to your wireless network, you need to take some additional
steps to

1. Change the default wireless
network name or SSID
ireless devices have a default wireless network name
or Service Set Identi
ier (SSID) set b
the
actor
. This
s the name o
your wireless network, and can be up
to 32 characters in length. Linksys wireless products

should chan

ormation (such as your Social Security
umber) because this information may be available for
n
one to see when browsing
or wireless networks.
2. Change the default password
For wire

you will be asked
or a password when you want to change
their settings. These devices have a default password set

Hackers know these de

to access your wireless device and change your networ
settings. To t

the device’s password so it will be hard to

3. Enable MAC address filtering
Linksys routers give you the ability to enable Media Access
Control (MAC) address filtering. The MAC address is a
nique series o
numbers and letters assigned to ever

device. With MAC address
ilterin
enabled,
wireless network access is provided solely for wireless
devices with speci
ic MAC addresses. For example,
ou can
speci
y the MAC address o
each computer in your home
so that only those computers can access your wireless
etwor
.
4. Enable encryption

WPA/WPA2
