Where to begin?  7 hours troubleshooting and I have not one question answered by tech support.  I have two m9 units.  The master has been placed in a variety of locations. It has been swaped with the 'slave' unit.  I have major slowdowns.  Should be getting 200mbps with Frontier.  When I check the speed of my wireless, It appears fine, but I am booted off often.  When I go into the app to check the speed....there are two places you can do this, right?  There is the "test internet speed" under router settings.  That says I am not connected (but I am).  Then you can check speed for each unit under overview/internet/all decos.  I have two.  Each one registers about 4kbps.  Thats it.  Welcome to the internet before the high speeds of dial up.  So what is it?  How can I be online with such slow speeds?  Why constantly getting kicked off.  There are obviously steps I have taken to check and recheck different things.  I am ready to go Eero but invested in these.  Anyone out there who can guide me gets a cookie and my gratitude (better than said cookie).
