AC1200 - EX6200 Devices able to connect but provide no internet.

Okay, I have an update.  I mentioned previously I have done a whole network reset trying to get it working.  I went to each device and selected "for get" or delete the previously set connectionn and then factory reset the extender, restarted it and shut it down.  Then I did the same with my ATT Gate; I factory reset and restarted it.  I have internet now through the extender after going to the genie procedure.   Looking back, I thought I had done a factory reset to my Gate but apparently I did not keep the reset button pressed long enough.  This time I waited about 30 seconds and before I took my finger off the reset button, I was perplexed to see all the lights lit up as in normal operation!  I remember the first time I did this waiting about 15 seconds and seeing the led lights still flashing; so maybe this was the difference.  Note to ATT Gate owners, be sure to keep your finger on the reset button until you see lights back to normal.   I will update maybe in about a week and then a Month later.   For now, I am crossing my fingers this will stay working.
