Last week I changed my wireless Security Settings from WEP to WPA-PSK+WPA2-PSK. At boot up the network connects just fine. After the laptop has gone into standby mode and I resume operation, the network status stays on "Acquiring network address" for a long time, and then fails completely. I open network connections, select the wireless network, click "connect", and it does not connect. Only if I click "repair", will it return a good connection. Rebooting the PC also works to reconnect the network. I think I must have failed to change a setting somewhere to match my new security settings. Can anyone recommend a solution?

I would reset the router to it's factory defaults and set it up again. To reset, with the unit powered up, push in and hold the reset button for about 10 seconds. Let it run for a minute or two afterwards so it can reboot. On your laptop, delete that old wireless connection (even if you use the exact same SSID on the router) and create a fresh one.

Curt R, thank you for your reply! I've reset the router, now how do I delete the old wireless connection? On my laptop I see the ssid listed in my available networks, but no way to delete it. Is this something I must do at the router?

sounds to me that the issue was with your laptop not the router. Make sure you set the wireless nic not to power down/sleep. This "disconnect" is a common problem when you let the system power manage the nic.

Wanderer, your solution does not provide specifics on how to "set the wireless nic not to power down/sleep". I right-clicked on "My Computer", selected "Properties", clicked the "Hardware" tab, clicked "Device Manager", right-clicked on my wireless Network Adapter, select "Properties", clicked "Advanced", select "Property:Power Save Mode", and changed the value to "CAM (Constantly Awake Mode). After that, for good measure, I changed my TCPIP setting to a fixed IP address, since searching for an IP address seems to take so much time. The problem is gone. Thank you very much.
