When using the card in 802.11n in access point mode, testing with file copying to or from a Windows system with an 802.11n card (specifically an Atheros 5416-based card in this card) with the other endpoint being accessed over 100 Mbps ethernet, after a short time it started to drop all packets, even after the transfer was stopped. Before the packet loss, the transfer is typically far below 802.11g's fastest rate. Fix: If ampdu is disabled, the packet loss does not occur. After that it can also at least reach, but not exceed, 802.11g rates. How-To-Repeat: Use mwl as 802.11n access point and copy a file over the network without a speed cap set.

batch change: For bugs that match the following - Status Is In progress AND - Untouched since 2018-01-01. AND - Affects Base System OR Documentation DO: Reset to open status. Note: I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
Is this still a setup you are running and did one and a half decades ago anyone think this mwl or our 11n implementation?
I am really sorry no one looked into this back then. I'll close it as I can no longer track all the 11n changes which may or may not have affected this. In the unlikely case you still have this setup and can still reproduce it, please re-open the PR.
