My apologies for replying to Frank's message in situ. But the original post had no air

of being router-specific, and my reply had only basic questions someone else would

need to ask as well in order to cut down on "playing the guessing game". Although IMO,

it seems wrongheaded somehow to go down such a specific path (i.e., your first link)

for something that appeared to be neither WiFi 6 nor hardware-related.

Thanks for the second link though.
