Ah, that did it. Thank you! I didn't see that option (8) in my search. Lots of
people disabling 802.11n completely, but that's kind of the opposite of what I
want :)
Do you, or anyone else here know what the actual issue is with some cards that
caused this change to be made? I saw one reference to a device reset happening
occasionally. I can say I have not seen such crashes or resets. If I do, I'll
report asap. Maybe it's related to various other settings hitting some odd
corner case in the wifi firmware.
Question is, why is it enabled in windows if it causes so many problems that
linux has to disable it by default? Do the windows drivers include fixed
firmware? Or maybe a more complex quirks list? It'd be interesting to see what
the two drivers do differently.
