Choose the Security Type for Wireless Network
Seng up wireless security is very important. Leaving your wireless network open and
unsecure could expose your enre network and personal les to outsiders. TRENDnet
recommends reading through this enre secon and seng up wireless security on your
new access point.
There are a few dierent wireless security types supported in wireless networking each
having its own characteriscs which may be more suitable for your wireless network
taking into consideraon compability, performance, as well as the security strength
along with using older wireless networking hardware (also called legacy hardware).
It is strongly recommended to enable wireless security to prevent unwanted users from
accessing your network and network resources (personal documents, media, etc.).
In general, it is recommended that you choose the security type with the highest strength
and performance supported by the wireless computers and devices in your network.
Please review the security types to determine which one you should use for your
network.
Wireless Encrypon Types
• WEP: Legacy encrypon method supported by older 802.11b/g hardware. This is the
oldest and least secure type of wireless encrypon. It is generally not recommended
to use this encrypon standard, however if you have old 802.11 b or 802.11g wireless
adapters or computers with old embedded wireless cards(wireless clients), you may
have to set your access point to WEP to allow the old adapters to connect to the
access point.
ÍNote:
• This encrypon standard will limit connecon speeds to 54Mbps.
• WPA: This encrypon is signicantly more robust than the WEP technology. Much of
the older 802.11g hardware was been upgraded (with rmware/driver upgrades) to
support this encrypon standard. Total wireless speeds under this encrypon type
however are limited to 54Mbps.
• WPA-Auto: This seng provides the access point with the ability to detect
wireless devices using either WPA or WPA2 encrypon. Your wireless network
will automacally change the encrypon seng based on the rst wireless device
connected. For example, if the rst wireless client that connects to your wireless
network uses WPA encrypon your wireless network will use WPA encrypon. Only
when all wireless clients disconnect to the network and a wireless client with WPA2
encrypon connects your wireless network will then change to WPA2 encrypon.
ÍNote:
• WPA2 encrypon supports 802.11n speeds and WPA encrypon will limit your
connecon speeds to 54Mbps.
• WPA2: This is the most secure wireless encrypon available today, similar to WPA
encrypon but more robust. This encrypon standard also supports the highest
connecon speeds. TRENDnet recommends seng your access point to this
encrypon standard. If you nd that one of your wireless network devices does not
support WPA2 encrypon, then set your access point to either WPA or WPA-Auto
encrypon.
ÍNote:
• Check the specicaons of your wireless network adapters and wireless appliances
to verify the highest level of encrypon supported.Below is brief comparison chart of
the wireless security types and the recommended conguraon depending on which
type you choose for your wireless network.
