I found a relatively cheap PCIe adapter labelled Fenvi FV-K1200ac that has an Intel 8265 chipset with ac1200 capability
and Bluetooth. Loaded the iwlwifi drivers, plugged it in and rebooted to a perfectly working Intel wifi adapter.
Not quite as fast as the Alfa (when working) but I think it's an antenna issue that I'll upgrade and try. The router is about
50ft away but connection speeds are 500Mbs+ and often over 700Mbs, which is many times faster than my Internet
connection anyway. But a reliable connection, at last.
Also updated my Stretch 9.6 from kernel 4.9 to stretch-updates v4.18. Fenvi still works and now has the latest drivers.
Had an issue with a missing Nvidia driver but easily resolved with apt as all the files were there, just not installed.
Recompiled the rtl8812au driver for the new 4.18 kernel and the disconnection problem still exists. It appears that something
in the params or driver is shutting down the adapter causing the disconnection and then needing either a LONG time
to recover or being physically disconnected (USB)-reconnected to regain the ability to make the wireless connection.
