Hi! For peoples who want to use linux WiFi drivers on FreeBSD with minimum support overhead :) This "how-to" (draft) describes how to use OpenWRT as driver with web GUI for WiFi adapters. No more pain with slow speed, no strange wpa_supplicant gui tools :) This upgrades WiFi speed from media: IEEE 802.11 Wireless Ethernet OFDM/36Mbps mode 11a to 866Mbps on my notebook with intel 8265. Resourses required: - 256 Mb ram - 128 Mb on hard drive - IOMMU support - FreeBSD AMD64 1. Download EFI based build. WWW: https://openwrt.org/docs/guide-developer/uefi-bootable-image cd /root/ fetch https://downloads.openwrt.org/snapshots/targets/x86/64/openwrt-x86-64-generic-squashfs-combined-efi.img.gz gunzip openwrt-x86-64-generic-squashfs-combined-efi.img.gz 2. Install sysutils/bhyve-firmware from ports. CSM not required. Patch required to build port (last attached): https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211074 3. Configure system: WWW: https://www.freebsd.org/doc/handbook/virtualization-host-bhyve.html https://wiki.freebsd.org/bhyve/pci_passthru echo 'net.link.tap.up_on_open=1' >> /etc/sysctl.conf /etc/rc.conf: kld_list="nmdm vmm" cloned_interfaces="tap0" ifconfig_tap0_name="wifi0" ifconfig_wifi0="DHCP up" ifconfig_wifi0_ipv6="inet6 accept_rtadv auto_linklocal -ifdisabled" /boot/loader.conf # bhyve PCI device passthru. # "1/0/0" - PCI dev ident, see: pciconf -lv pptdevs="1/0/0" # For AMD systems hw.vmm.amdvi.enable="1" 4. Start OpenWRT /usr/sbin/bhyvectl --destroy --vm=owrt /usr/sbin/bhyve \ -A \ -H \ -c 2 \ -m 256M \ -S \ -s 0:0,hostbridge \ -s 1:0,lpc -l com1,stdio \ -s 3:0,ahci-hd,openwrt-x86-64-generic-squashfs-combined-efi.img \ -s 5:0,e1000,tap0,mac=00:be:fa:76:45:01 \ -s 7,passthru,1/0/0 \ -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \ owrt To disable output remove: "-l com1,stdio" "1/0/0" - PCI dev ident, same as in loader.conf. 5. Configure OpenWRT: uci set network.lan.ipaddr='172.16.0.49' uci set network.lan.netmask='255.255.255.0' uci set network.lan.gateway='172.16.0.254' uci add_list network.lan.dns='172.16.0.254' uci commit network /etc/init.d/network restart opkg update opkg install luci Now web GUI can be used to install wpad*, hostapd*, WiFi driver and other staff. If you want use OpenWRT as bridge - read this: https://openwrt.org/docs/guide-user/network/wifi/relay_configuration Better to start with simple rourer+nat mode.
