>That device has an embedded web server for configuration. You can access that site and check the wireless configuration to see if it supports WPA. There does not seem to be any updated firmware available from D-Link so what you see in the web config is all that's available.

The new router fiberop I have is set to WPA or WPA2. The D-Link shows it at WPA - PSK. So, I assume it is not the same thing. Thus, it might not support it. If I use WEP, the wireless works. But, I need to use WPA. When it is the case, the router recognizes the IP address of the device, but I cannot ping the device. It's been a while since I have it. So, I assume this advanced security was not fully supported on that device then.

>These days even WPA is considered "busted" from a security POV. You should be using some flavour of WPA2 on all your wireless devices.

... as per the above paragraph, the setting is set on both.

Yes, a very long one.
