If you are certain that you have disabled wireless security in the router (and this includes not only encryption but anything else you might have set in an effort to increase security, such as MAC filtering) and still cannot connect, there are only a limited number of possibilities. You have eliminated most of them by saying that your laptop successfully connects to other wireless networks. First, clear out remnants of prior attempts to connect to your network. Go to Network Connections and right click on the icon for your wireless adapter and choose Properties. Select the Wireless Networks tab and Remove all entries that have your SSID. OK your way out. Now click the View Wireless Networks tab, locate your SSID in the list of available networks, and click Connect. I'll assume that you can't connect. Go back to your router's configuration utility (from a wired computer) and determine what wireless mode it is set to. The DIR-655 is a wireless-N router, but it can be set to operate as G-only, G&B, B-only, N-only, or mixed N,B,G. Make sure that the mode is compatible with your wireless adapter. If you don't know what your wireless adapter is, either set the router to Mixed N,B,G or (better) look up your adapter's model number in Device Manager and Google it. With respect to the level of security, Win XP sp3 supports (is "compatible with") WPA2-Personal if (and this is a big if) the wireless hardware in your laptop supports that. If your adapter is somewhat elderly, you may need to update a driver. See the website of your laptop's manufacturer for the appropriate driver. You should be able to determine what level of encryption is supported by your laptop's wireless adapter by going back to the Wireless Networks tab of the wireless adapter's Properties dialog, selecting a Preferred network from the list and clicking the Properties button. On the Association tab, you'll see a drop down box for "Encryption." Click the arrow and you should see the possibilities. -- Lem Apollo 11 - 40 years ago: http://www.nasa.gov/mission_pages/apollo/40th/index.html
