I was on the phone today with Linksys elevated support for more than 2 hours.

Here is the bottom line so maybe you won't have to suffer as I have.

Step 1:  Upgrade the firmware.  In my case, I went from whatever to 1.1.7.160.177.

Step 2:  Under Connectivity > Internet Settings, enable "MAC Address Clone".  

Step 3: Click "Clone My PC's MAC".

Step 4: Click "Apply"

Done.  Problem solved.
