+
+With multiple wireless projects ongoing, this report focuses on the efforts using permissively licensed Linux wireless drivers mostly unmodified on FreeBSD.
+
+Drivers previously committed directly to FreeBSD src.git were retroactively imported in vendor branches and merged to main.
+This makes maintenance and identifying local changes a lot easier.
+The man:iwlwifi[4], man:rtw88[4], and man:rtw89[4] drivers got updated in main to match Linux 6.11.
+
+The man:rtw89[4] driver, which had been ported and in the tree for a while, got connected to the build.
+Thanks for that goes to the efforts of the community finding two bugs preventing it from working before.
+
+Wireless firmware in ports got updated and a release flavor was added.
+The release building framework got enhanced to install the firmware packages onto the release media.
+The installer grew support to run man:fwget[8] on the installed system to install the firmware.
+This all together ensures that (wireless) drivers with external firmware can be used from the installer and right away on the installed system without the need for alternate connectivity.
+With the framework in place for man:iwlwifi[4], man:rtw88[4], and man:rtw89[4] support for more drivers can easily be added in the future.
+These changes shipped the first time with 14.2-RELEASE.
+
+Having a lot of these requested necessities out of the way, time was spent on HT(802.11n) and VHT(802.11ac) improvements to the LinuxKPI framework synching between driver and net80211.
+Hardware crypto offload got sorted along with A-MPDU RX/BA offload right at the end of the year.
+Both were needed towards the goal to achieve higher throughput with man:iwlwifi[4].
+
+A half-year old bug, which stayed unnoticed preventing packets to be sent beyond scanning with man:rtw88[4] in main and stable/14, received a patch to fix the situation.
+
+Work for the first quarter of 2025 should include:
+
+* finishing basic HT and VHT support, and
+* looking at finishing the code for generic LinuxKPI 802.11 suspend/resume support
