There has been a large amount of work on iwn(4) over + the last six months:

+ +

New hardware support, 2xxx, 6xxx, 1xx series hardware.
Many bugs fixed, including scanning, association, EAPOL related + fixes.
iwn(4) now natively works with 802.11n rates from the + net80211 rate control code, rather than mapping non-11n rates to 11n + rates.

+ + + + There are still some scan hangs, due to how net80211 scans a + single channel at a time. This needs to be resolved. + + The transmit, receive, scan and calibration code need to be + refactored out of if_iwn.c and into separate source + files. + + There still seem to be some issues surrounding 2 GHz + vs. 5 GHz association attempts leading to firmware + assertions, especially on the Intel 4965 NIC. + +
