1. For Windows 2000/XP, if the installation menu does not appear automatically, click Start,
click Run, and type D:\autorun where "D" in "D:\autorun.exe" is the letter assigned to your
CD-ROM Drive, and then press the ENTER key on your keyboard.
2. For Windows Vista, if the installation menu does not appear automatically, click on the
Windows Icon on the bottom left hand corner of the screen, click on the “Start Search”
box, and type D:\autorun.exe, where “D” in “D:\autorun.exe” is the letter assigned to your
CD-ROM Driver, and then press the ENTER key on your keyboard.
3. For Windows 7, if the installation menu does not appear automatically, click on the
Windows Icon on the bottom left hand corner of the screen,, click the “Search programs
and files” box, and type D:\autorun.exe, where “D” in “D:\autorun.exe” is the letter
assigned to your CD-ROM Driver, and then press the ENTER key on your keyboard.
I completed all the steps in the quick installation guide, but my Wireless USBAdapter is not
connecting to my access point. What should I do?
1. Verify that the SSID matches your wireless router or access point's SSID.
2. Please check with your network administrator for the security key in order to access a
secured wireless access point or router. Refer to the User's Guide for more information
regarding wireless network security.
3. Check your TCP/IPproperties to ensure that Obtain an IPaddress automatically is
selected.
4. Double-click the Wireless Configuration Utility icon, click Site Survey and then click
Refresh to check and see if there are any available wireless networks listed.
Windows is unable to recognize my hardware. What should I do?
1. Make sure your computer meets the minimum requirements as specified in Section 1 of
this quick installation guide.
2. You must complete the installation of the Wireless Configuration Utility (as described in
Section 2) before connecting the Wireless USBAdapter to your computer.
3. Connect the Wireless USBAdapter to a different USB port on your computer.
I cannot open the Wireless Configuration Utility. What should I do?
Access your device manager to make sure the adapter is installed properly. If you see a

the User's Guide included on the Utility & Driver CD-ROM or contact TRENDnet'sTechnical
Support Department.
Abaixo algumas dicas genéricas sobre wireless para ajudar a minimizar o impacto de
interferências em determinado ambiente.
Atribua à sua rede um SSID único. Não use nomes de fácil identificação como “Rede da Família
Silva”. Escolha algum que você identifique facilmente quando pesquisar por redes wireless
disponíveis.
Não desative o broadcast de SSID. O broadcast de SSID é para estar ligado e desligá-lo pode
causar problemas na conectividade. O melhor método para se proteger uma rede wireless é
escolher uma forma de criptografia forte e uma chave de criptografia forte e diferente.
Altere o canal.Amaioria dos pontos de acesso e roteadores wireless vêm pré-ajustados para o
canal 6. Se você tem uma ferramenta de site survey que apresenta o canal das redes localizadas,
você poderá escolher seu canal em função dos pontos de acesso para minimizar interferências
provenientes deles. Se sua ferramenta não informa o canal das redes, experimente usar o canal 1
ou 11.
Se você utiliza ponto de acesso ou roteador 802.11n você também pode fazer as seguintes
mudanças.Altere a largura do canal (channel bandwidth) para 20/40 MHz. Isto proporcionará a
maior performance possível em dispositivo 802.11n. E também, em utilizando 802.11n você
poderá proteger a rede com segurança WPA2.
Por favor, certifique-se também de que o equipamento sem fios não seja colocado em qualquer
tipo de prateleiras ou caixas.
Evite empilhar equipamentos uns sobre os outros para prevenir problemas de sobreaquecimento.
Mantenha bastante espaço livre no entorno do equipamento para assegurar fluxo de ar e boa
ventilação. Também deve haver espaço livre no entorno das antenas para permitir a propagação
do sinal wireless.
Nota: após configurar o SSID, o tipo e a chave de criptografia, favor anotá-los para referência
futura. Você necessitará deles para conectar seus computadores wireless ao ponto de
acesso/roteador wireless.
Nota: Devido a considerações da certificação Wi-Fi, se você escolher criptografia WEP, WPAou
WPA2-TKIP o equipamento irá operar em modo wireless legado (802.11b/g). Você pode não
atingir performance 802.11n uma vez que estes tipos de criptografia não são suportados pela
especificação 802.11n.

Dicas Wireless
Há diversos outros fatores ambientais que podem influenciar o alcance de dispositivos wireless.
1.Ajuste seu dispositivo wireless de forma que o sinal seja transmitido em uma reta em vez
de um ângulo. Quanto mais material o sinal tenha de atravessar maior a perda de sinal.
2. Minimize a quantidade de obstruções. Cada obstrução pode reduzir o alcance de um
dispositivo wireless. Posicione os dispositivos wireless de forma que a quantidade de
obstruções entre eles seja a menor possível.
3. Materiais de construção podem ter grande impacto no sinal wireless. Em ambiente
interno, tente posicionar os dispositivos wireless de forma que o sinal passé através dos
materiais menos densos. Materiais densos como metal, madeira, vidro ou mesmo
mobília podem bloquear ou degradar o sinal;
4. O posicionamento da antena também pode ter grande impacto em seu sinal wireless. Use
a ferramenta de site survey de seu adaptador wireless para determinar a melhor posição
para seu dispositivo wireless.
5. Interferência de dispositivos que geram ruído RF (radio frequência) também podem afetar
seu sinal. Posicione seus dispositivos wireless afastados de qualquer produto que gere
ruído RF, tais como fornos de microondas, rádios HAM, Walkie-Talkies e babás
eletrônicas.
6. Qualquer dispositivo operando na frequência de 2.4 GHz causará interferência.
Dispositivos como telefone sem fio 2.4 GHz ou outros remotos sem fio operando na
frequência de 2.4GHz podem derrubar o sinal wireless. Mesmo que o telefone não esteja
sendo utilizado, a base pode estar transmitindo sinal wireless. Coloque a base do
telefone tão distante quanto possível de seus dispositivos wireless.
Se você ainda estiver com sinal baixo ou sem sinal considere reposicionar os dispositivos wireless
ou instalar pontos de acesso adicionais.O uso de antenas de alto ganho, dependendo do
ambiente, também pode proporcionar a cobertura.
