After adding (or changing) wireless devices, hardware, firmware, or drivers, your network client(s) may stop working. There are a variety of possible causes. This process has a high success rate in restoring your wireless connection.

Note: Network Devices are self-contained devices such as your broadband modem, routers, Access Points, bridges, gaming adapters, multimedia player(s), and print servers.

For most small home networks, this process takes about 5 minutes and requires no special technical knowledge. You must have access to the configuration utility or web pages for your wireless Network Devices.

•Using your router/AP's configuration method, set the router/AP to factory defaults, or set/confirm the following settings (these are usually the default settings):
•The Wireless AP is sent to Broadcast/Not Hide the SSID.
•The Wireless AP Security is set to the encryption method that you want to use.*
•The Wireless AP Security or Router Security does not perform MAC Filtering or Access Control.
•The Router Security does not perform IP Filtering. (does not apply to non-router APs)
•The Router's DHCP server is enabled and an adequate range of IP addresses are available. (does not apply to non-router APs)
•Tip: It is sometimes useful to change the SSID to something you have never used before. In most cases, this is not necessary. In any case, it does no harm.
•Remember to save your settings

•Delete any/all of the saved profiles for this router from your wireless computer(s) and Network Devices.
•Unplug power from Network Devices.
•Shut down your computers.
•Starting with your broadband modem, and working inward, plug in or restart your Network Devices and computers. Wait for each Network Device to complete its process of booting and synchronizing. Log in to each wireless computer or Network Device and configure it to your network. You should be able to connect normally.

This is a good process to follow if you find that you have problems connecting, or remaining connected, after adding Network Devices, updating drivers or firmware, or changing security methods for your wireless network.

*If you cannot connect at the end of these steps, repeat this process but use No Encryption. This will allow you to better troubleshoot the source of the issue.

This is by design.

Contrary to what may be printed in the D-Link user manual, the WLAN light normally blinks steadily. The WLAN is not lit when the wireless radio is turned off. Otherwise, a dark WLAN light is an indication of a hardware problem.

Note that pae is eap spelled backwards.

In the more advanced types of wireless security, an Extensible Authentication Protocol (EAP) is used. EAP was originally designed to secure dial-up connections, but was extended to multiple IEEE 802 "Wi-Fi" standards. As suggested by the name, EAP is able to handle multiple different types of security -- most popular in the wireless world: 802.1X, WPA (Radius), and WPA-PSK.

An EAP disconnect once in a while is probably normal.

A repeating cycle of EAP disconnects, or an EAP disconnect that will not reconnect is not normal. If this happens, see /faq/12948.

Firmware 2.52 through 2.70 seem to have a known DHCP problem in WPA modes.

Do this on the DI-624:
•Using firmware 2.50 or 2.71, set the router to the Factory Defaults.
•Then reconfigure by hand (do not restore settings from a file).
•Leave the SSID broadcasting/SSID hidden feature enabled (the default value).
•Unplug power to the unit.

Then do these steps on the wireless computer:
•Using Add/Remove programs, remove the manufacturer's Configuration Utility, but do not remove the drivers.
•Reboot this computer.

Now restore power to the DI-624. When the AP is detected, Windows will let you know.* Click on the bubble, connect to the SSID, fill in your WPA passphrase. You should now be successfully connected.

----
* if this doesn't happen, click on Start, Run and type services.msc. Go down the list to Wireless Zero Config and double-click it. Set the startup type to Automatic and then click Start. Click OK. You should get the notice after a few seconds.
