[ath9k-devel] Ath9k performance testing results (AR9380)

Ok, so thanks for all the suggestions and numbers that folks have posted in the 'wifi throughput tests' thread. Short answer: 352Mbps download, 270Mbps upload (not concurrent). We set up two systems, both with WPEA-127N NICs (AR9380). The Station machine is dual-core Atom, 3.3.7+ 32-bit kerne

[ath9k-devel] DISABLE AMPDU AGGREGATION

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

Re: [ath9k-devel] MPDU size and fragmentation issues

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. On Mon, May 28, 2012 at 11:11 PM, Adrian Chadd wrote: > Fragmentation is not allowed with A-MPDU in 802.11n. > > > > Adrian

Re: [ath9k-devel] MPDU size and fragmentation issues

Hi, I believe this is so - 802.11n aggregation is on entire A-MPDUs, not fragments. Adrian ___ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
