DHCP recently stopped working for em0. HP EliteBook 8570p, recently probed: <https://bsd-hardware.info/?probe=e90abb54c9>; Any ideas? For what its worth, the problem _might_ have begun after a package upgrade routine on Tuesday 20th April: <https://bsd.to/nWBw/raw>; I updated the sytem (from n246123-21afed4b1d1 to n246330-5eb9c93a20d), no improvement. /etc/rc.conf – includes the following lines: ifconfig_em0="DHCP" create_args_wlan0="country GB regdomain etsi" wlans_iwn0="wlan0" ifconfig_wlan0="NOAUTO WPA SYNCDHCP" When I use a static address in lieu of DHCP: no problem. wlan0 is fine (albeit slow) with DHCP, % date ; uname -v Tue 27 Apr 2021 12:10:08 BST FreeBSD 14.0-CURRENT #93 main-n246330-5eb9c93a20d: Tue Apr 27 05:14:26 BST 2021 root@mowa219-gjp4-8570p:/usr/obj/usr/src/amd64.amd64/sys/GENERIC-NODEBUG % ls -ahlrt /var/run/dhclient/ total 1 drwxr-xr-x 2 root wheel 3B 27 Apr 07:00 . -rw-r--r-- 1 root wheel 5B 27 Apr 07:00 dhclient.wlan0.pid drwxr-xr-x 22 root wheel 44B 27 Apr 07:25 .. % bectl list -c creation BE Active Mountpoint Space Created r357746-Waterfox - - 59.2G 2020-03-10 18:24 n245827-361e9501800-a - - 10.9G 2021-04-05 18:48 n246123-21afed4b1d1-f - - 783M 2021-04-26 03:18 n246330-5eb9c93a20d-a NR / 112G 2021-04-27 06:14 % ---- root@mowa219-gjp4-8570p:~ # date ; time service netif restart em0 Tue Apr 27 12:16:53 BST 2021 dhclient not running?
