Troubleshooting

This chapter provides solutions to problems that can occur during the installation and operation of the DHP-W220AV.  Read the 

following descriptions if you are having problems. The examples below are illustrated in Windows® XP.  If you have a different 

operating system, the screenshots on your computer will look similar to the following examples.

1. Why can’t I access the web-based configuration?

When entering 

http://dlinkap.local.

, you are not connecting to a website nor do you have to be connected to the Internet. 

The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to connect 

to the web-based utility. 
Make sure you have an updated Java-enabled Web browser. We recommend the following: 

•  Microsoft Internet Explorer® 8.0 or higher

•  Mozilla Firefox® 12.0 or higher

•  Google™ Chrome 20 or higher

•  Safari® 4.0 or higher

Verify wireless connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different 

device if possible.

Disable any Internet security software running on the computer. Software firewalls such as ZoneAlarm, BlackICE, Sygate, Norton 

Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the help files included with 

your firewall software for more information on disabling or configuring it.
