I recently purchased a Samsung Smartphone which works great but will not connect to my secure wireless network. I have an older D-Link DIR-625 rev a draft N router with other devices connected to it. I am using Network Magic software which makes adding new devices simple. When I turn on the phone's Wi-Fi setting, it scans for local networks, and recoginizes mine. I add the correct passphrase but the phone will not connect. I am using MAC filtering on my network so I went on to the admin page and added the phone's mac id. Still no connection. This smartphone is not very smart.
