So, I was correct it does "disconnect" still every once in awhile.... Sometimes it does it several times in a period. Though, more often it goes for a good while without a disconnect. But, it's random.
I also put the setting for the 2.4Ghz back to 20Mhz and put the Preferred connection to 5Ghz, though I still appear to be connecting to the "g" network rather than "n". No disconnects yet..... So, it appears with the 16.0.0.62 driver that the only "important" setting to change is the Roaming Aggressiveness changed to Highest. So far anyway, further observation will tell.
One thing though I'm wondering..... When I first got this computer it was always connecting to the "n" network, and then I started changing drivers, settings on the router and in the driver etc. Now it NEVER connects to the "n" network....??? Is there some setting in the router I might have changed that is causing it to only connect to "g" now, or is it the Roaming setting from Medium to Highest that makes it only connect to "g" now? The one setting that you select what networks you allow connecting to the router is still the same b, g, n or whatever.
Strange....
