Troubleshooting
1. Why can’t I access the web-based conguration utility?
• We recommend the following:
- Internet Explorer® 7.0 or higher
- Firefox
- Chrome
- Safari 4.0 or higher
• Windows® Users: Make sure you have the latest version of Java
installed on your computer. Visit www.java.com to download.
• If you are using the DAP-1665 in Access Point Mode, verify physical
connectivity between the access point and your router. The
LAN LED on the device should be illuminated, indicating that a
connection is established. You should also ensure that your router’s
Ethernet port is enabled and functioning properly.
• If you are using Wi-Fi to connect to the router or access point,
ensure that your are connected to the correct wireless network,
and that there are no connectivity problems. If you are still unable
to access the conguration utility, try connecting to the router or
access point using the included Ethernet cable.
18DAP-1665 Install Guide
2. What can I do if I forgot my password?
If you forgot your password, you must reset the DAP-1665. Unfortunately
this process will change all your settings back to the factory defaults.
To reset the access point, locate the reset button (hole) on the rear
panel of the unit. With the access point powered on, use a paper clip
to hold the button down for 10 seconds. Release the button and the
access point will go through its reboot process. Wait about 30 seconds
to access the access point. When logging in, the username is Admin
and leave the password eld empty.
3. How do I add a new wireless client or PC if I have forgotten my
wireless network name (SSID) or wireless encryption key?
• If you have not changed your Wi-Fi settings from the factory
defaults, you can use the information from the provided Wi-Fi
Conguration card to connect to the router or access point.
• If you have changed your Wi-Fi settings, you should access the webbased conguration utility as described on page 14, and complete
the Setup Wizard again.
• Make sure you write down the settings displayed at the end of
the Setup Wizard, so that you can enter them into each wirelessly
connected device.
