Hi,
I've flipped on ATH_ENABLE_11N and the interrupt mitigation in i386 and amd64 GENERIC. I'll flip it on on PPC when someone (chmee?) verifies that 802.11n works on PPC. It's still delicate. I still don't know if RTS/CTS HT frame protection is working quite right on all chips. But all the basics are there (software TX aggregation, RX AMPDU reordering in net80211, BAR transmission, software queue pause and unpause, frame retransmission.) Don't be surprised if your 802.11n mobile devices perform poorly as the power queue handling is very broken and will result in all kinds of weird traffic stalls if things are too aggressive. I'll look into fixing that soon. If you have problems, please read the wiki article: http://wiki.freebsd.org/dev/ath(4) - specifically the bits where I tell you to compile with the debugging and diagnostic stuff in your -HEAD kernel, including the HAL/driver diagnostic APIs and tools. Enjoy, Adrian _______________________________________________ [hidden email] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "[hidden email]" |

I've also just created a wiki page which provides a very basic overview of the debugging tools for the driver: http://wiki.freebsd.org/dev/ath(4)/Debugging I'll write one for net80211 tomorrow. It turns out 'wlanstats' is really damned helpful. adrian _______________________________________________ [hidden email] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "[hidden email]" |

I would, but I don't have any other 802.11n hardware but the one card, and I have problems with that one on 802.11g, which I'll track down when I get some time, might have some time to test this weekend. - Justin _______________________________________________ [hidden email] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "[hidden email]" |

Hi,
The AR5414 should support it. I just havent implemented the same changes in the ar5212 HAL. Look at ar5416_ani.c and ar5212_ani.c. adrian _______________________________________________ [hidden email] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "[hidden email]" |

I did my duty as PPC guinea pig, and can happily say that unlike other cards *cough*bw{i,n},wi*cough* I can actually use ath on my PowerBook. AR5416, about as stable as I've seen so far. I think you can flip it on PPC now. > > It's still delicate. I still don't know if RTS/CTS HT frame protection > is working quite right on all chips.
