Ensure the "VHT 2.4G" and "VHT 5G" options are enabled in the driver settings.

The (RTL8188ETV / RTL8188EU) improved upon the ‘C’ variant with better PHY circuitry and thermal management.

Force "IEEE 802.11ac" if you have an 8811a/8812a to ensure it doesn't default to slower "N" speeds. i--- Rtl8188c-8188e-8192c-8192e-8811a-8812a

Many “AC600” dongles now use the inferior MediaTek MT7610U. Verify with lsusb before purchase.
