I put the Chromecast into my HDMI tv and downloaded the app to my Android phone and my Android Tablet. My laptop which is Windows Vista says it is not supported. When I try to connect to my wifi from my android devices it says it can't find Chromecast. I have researched and read that my upnp needs to be enabled on my Qwest (now Centurylink) Actiontec Q1000 modem and called century link to have them enable it, since I was not able to on my end. They said that all their modems come with upnp already enabled. So now I am stuck, How do I get my Chromecast to connect to my wifi???
Did I maybe get a bad device??

I have a Q1000 modem also and was having trouble getting Chromecast to connect to the Internet. Solved problem by opening some Service Ports for UDP traffic. A few Q1000 router settings need to be changed.
Enter the address 192.168.0.1 in a browser window. Then click on "Advanced Setup" followed by clicking on Firewall listed under Security. In table #4, "Set the Firewall table below. Services checked are allowed.", check the Traffic In and Traffic Out boxes for DirectX, Direct TV STB 1, Direct TV STB 2, and Direct TV STB 3. Note that the ports are for Multimedia Control and Services. After checking the boxes scroll to bottom of page and click "Apply."
After the router applied the changes, my Chromecast device started working.
Hope this helped.
