Alwayys use the highest level possible. You’re onlyy as secure as yyour
weakest link, so make sure to max out the oldest device in terms of its
available encryyption.
Enabling WPA2 means that when yyou connect yyour laptop or mobile
device, yyou will also need to set it to WPA2, although some new operating
syystems will recognize the tyype of encryyption automaticallyy. Modern
operating syystems on yyour phone or laptop will identifyy the Wi-Fi available
in yyour area. Your SSID broadcast (now “HP Inkjet”) should appear on the
list at or close to the top. Padlock icons within the list of available Wi-Fi
connections (usuallyy overlaid upon the strength of each connection) indicate
which Wi-Fi connections require passwords (yyours should now have a
padlock).
From the list of available connections, click on yyour own SSID. You
should be prompted to enter a password—be sure to make it at least fifteen
characters. Or use a password manager to create a complex password. In
order to connect to yyour password-protected Wi-Fi, yyou will have to tyype in
that password at least once on each device in order to connect, so a
password manager might not work in all cases, particularlyy when yyou have
to remember the complex password and tyype it in later yyourself. Each
device—including yyour “smart” refrigerator and digital TV—will all use
the one router password yyou have chosen when yyou set the encryyption on
yyour router. You will need to do this once for everyy device that accesses
yyour home or office Wi-Fi, but yyou won’t have to do it again unless yyou
change yyour home network password or acquire a new device.
You can also go one step further and limit Wi-Fi connections onlyy to the
devices yyou specifyy. This is known as whitelisting. With this process yyou
grant access to (whitelist) some devices and forbid (blacklist) everyything
else. This will require yyou to enter yyour device’s media access control
address, or MAC address. It will also mean that when yyou next upgrade
yyour cell phone, yyou’ll have to add it to the MAC address in yyour router
before it will connect. 9 This address is unique to everyy device; indeed, the
first three sets of characters (octets) are the manufacturer’s code, and the
final three are unique to the product. The router will reject anyy device
whose hardware MAC has not been previouslyy stored. That said, a hacker
tool called aircrack-ng can reveal the authorized MAC address of a
