Sees network but can't connect

Just bought the WDTV Live Streaming and I need some help connecting to my network. I am on FIOS in NJ and I am using their ActionTec router. When I power up the WD, it sees my network, but, after entering my network password, I get an “unable to connect” screen. I triple-checked the network password, but no go. Any help would be greatly appreciated. I have networked a laptop, netbook and a Blu-Ray player in the past with no issues so I’m not sure what I’m doing wrong. Thanks                                                        Sorry, will repost in networking section

What if you manually configure the network settings and/or change the wireless encryption type?

I manually entered all info. What finally worked was using a static address for the WD( did not know that had to be done as all other wireless equipment I networked was found much easier ). Once it was up and running, it works as well as I hoped for. Thanks for the reply
