https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D278935 Bug ID: 278935 Summary: [wlan] [iwlwifi] fails to establish a connection, or fails to maintain it Product: Base System Version: 14.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: wireless Assignee: wireless@FreeBSD.org Reporter: dch@freebsd.org This is my 14.0-RELEASE old Dell XP13 laptop, with an intel 8265 nic swapped in, this has been pretty solid for many years on iwm, including suspend/resume. Swapping to iwlwifi periodically during last years development has generally worked fine, but I've had problems recently where the laptop can't make the connec= tion to the network at all, or makes a connection, and then drops it minutes lat= er. BAD STARTUP: wlan0: flags=3D8c43<UP,BROADCAST,RUNNING,DRV_OACTIVE,SIMPLEX,MULTICAST> met= ric 0 mtu 1500 options=3D0 ether 00:28:f8:d0:91:52 inet 172.16.2.21 netmask 0xffffff00 broadcast 172.16.2.255 inet6 fe80::228:f8ff:fed0:9152%wlan0 prefixlen 64 scopeid 0x2 groups: wlan ssid "" channel 1 (2412 MHz 11g) regdomain ETSI2 country AT authmode WPA1+WPA2/802.11i privacy ON deftxkey UNDEF txpower 30 bmiss 7 scanvalid 60 protmode CTS wme roaming MANUAL parent interface: iwlwifi0 media: IEEE 802.11 Wireless Ethernet autoselect (autoselect) status: no carrier nd6 options=3D23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL> Sometimes it works: GOOD STARTUP: wlan0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 15= 00 options=3D0 ether 00:28:f8:d0:91:52 inet 172.16.2.21 netmask 0xffffff00 broadcast 172.16.2.255 inet6 fe80::228:f8ff:fed0:9152%wlan0 prefixlen 64 scopeid 0x2 groups: wlan ssid skunkwerks channel 1 (2412 MHz 11g) bssid 80:2a:a8:84:e2:a3 regdomain ETSI2 country AT authmode WPA2/802.11i privacy ON deftxkey UNDEF AES-CCM 2:128-bit txpower 30 bmiss 7 scanvalid 60 protmode CTS wme roaming MANUAL parent interface: iwlwifi0 media: IEEE 802.11 Wireless Ethernet OFDM/24Mbps mode 11g status: associated nd6 options=3D23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL> And then stops a minute or two later.

I've attached ifconfig, dmesg, from the relevant phases with most of the=20 wifi debug flags turned on. I don't know what I'm looking for, but it's as if the firmware gets stuck and just won't work. Switching to iwm sometimes seems to reset it, but not always. --=20 You are receiving this mail because: You are the assignee for the bug.=
