Are you on an IPv6 address or IPv4? If IPv6 are you sure the BQM is pinging the router, or the device you are using when you set up the BQM?
I fell into thta trap when I first got IPv6, as the tbb "What is my IP address", and all other checking sites, and the BQM default when you click to set it up
pick up the device. On IPv4 they pick up the router as your device is NAT'd behind that.
