Answer 1

I had the same issue with Comcast xFinity and Compass.

Update for Windows 7 users:

Go to Control Panel > Network and Sharing Center
Under "Active Networks" select "Connections: Local Area Connections"
In the "Local Area Connection Status" dialogue box, click on "Properties"
Double click the IPv4 item
In the "Internet Proptocol Verion 4" icon or click the "Properties" button, then click "Advanced"
In the DNS tab, just above the 2nd input box, click the "Append These DNS suffixes (in order)" radio button,
    then click "Add", enter "home.lan", then click OK until the dialogue closes.

    Many thanks to John Smith for the Vista fix and Somnambulent for Win 8.1 fix.
