Dear Adrian,
We are running some tests to see how the frame transmission attempts evolve
in cases that the medium is used only by a single terminal.
In a low-quality link, we configure the 54 Mbps legacy rate
and observe that although the frame delivery rate is quite low (30%),
the transmission a
Hello,
I am using the AR9380 chipset that supports up to 3x3 MIMO transmissions.
I ues two PCs with the same chipset and assign the 3x3 configuration.
Using the default MINSTREL and also fixed MCS by enabling the debugfs, as
proposed here:

Hello,
I am about to order some new cards for testing capabilities of ath9k.
Currently I have cards with the AR5008, AR5418 chipset, which does not
support 3x3 MIMO.
I looked in the list of ath9k-supported chipsets to find cards that
support 3x3 MIMO and I have concluded in the following options

Hi Adrian,
do you mean that fragmentation is not supported by the standard and as a result
it has not been implemented in ath9k?
Thanks,
Stratos.

HI,
I checked in the archives and found that a proper way to disable AMPDU
aggregation is to
replace these two lines in /drivers/net/wireless/ath/ath9k/init.c of
function ath9k_init_misc()
sc->sc_flags |= SC_OP_TXAGGR;
sc->sc_flags |= SC_OP_RXAGGR;
with the following:
sc->sc_flags &= ~SC_OP_TX
Thank you very much for your fast reply!

Hello,
I am working on a project that uses ath9k with adaptive frame length.
As I can see the default packet size is around 1540 bytes.
I check this through various functions and I list some instances here:

// The lase value is eq
