The D-Link DIR 655 router is an excellent router. I don't believe your problem is with the router though. For best results with different wireless settings among different devices let's set up your router to work with different types of wireless devices and see if this helps. On the setup page click on Wireless settings on the left side, and then on the bottom of the screen click on Manual Wireless Network Setup. Once you have done this you should see a page similiar to the image below. Under Wireless Network name which is the SSID, give a name that will be easy for you to identify your wireless router. Under 802.11 Mode, select Mixed unless you know for sure that you do not have any wireless 802.11b devices in your house. Mixed mode is the best to make sure all your wireless devices can connect. That will complete the Wirelss Network Settings area of that page as everything else should be defualts. On the same page though under Wirelss Security Mode, click on the drop down and select WPA-Personal. Once you do this, some more options will be available. WPA Mode should be Auto (WPA or WPA2) and Cipher Type should be TKIP or AES. Under Pre-Shared key, type in a key that you can remember. This will be the password or key that each of your wireless devices will need in order to connect properly. It is possible that your wireless devices can connect to the router without the correct password, but without the correct key, your devices will not get IP addresses nor will they be allowed to pass traffic over the wireless connection. If you have done all these steps and you are still having problems let me know.
