Myron,
I tried rebooting both my router and the MBL the first time I tried editing the file.
So I exited from Dashboard, and re-entered.
This time, I went straight for the “Network” test and got a “Good.”
So then I went to the Update Check and got “No Network Connection.”
I checked that the “Network” screen still showed a “Good” and went back to the Update Check. This time I got the “Your Firmware is Up To Date” message.
Very flaky. But now my MBL is more like yours than it was!
