Wlan0 no carrier after upgrade from 13.1 to 13.2

I just upgrade my laptop from 13.1 to 13.2 via freebsd-update(8) and now my wlan0 says no carrier. My ifconfig says:
Code:

So it seems that the iwm0 is working...

What did I miss?
 
I think I read a similar title. I look? Beyond a possible failure, I would start looking (and sharing) in /etc/rc.conf and /etc/wpa_supplicant.conf, if you need to preload any firmware (dmesg, kldstat, /boot/loader.conf) and if the services are running wpa, dhcp...
Checking
cat /var/log/wpa_supplicant.log
 
The machine is @home, I have taken some excerpts to keep it short:

from /etc/rc.conf:
Code: 
wlans_iwm0="wlan0"
ifconfig_wlan0="WPA DHCP"
from /etc/wpa_supplicant.conf (psk censored :):

I'll try to put that in /etc/rc.conf when back home and report the results afterwards.

Thanks for the hint.
 
It makes no difference, only ifconfig says regdomain ETSI country Italy. The behaviour of wpa_supplicant is the same, same errors, same ifconfig scan.
 
Not the same behavor: mine doesn't work even after the boot...

I'll continue testing later on and keep you posted.
 
I did surrender.
Rollbacking to 13.1 did the trick.
I see the same kernel modules loaded:

and the wpa_supplicant is the same.
 
Hi.
Try to simplify the /etc/wpa_supplicant.conf

In may case with the same card:

Code: 
ctrl_interface=/var/run/wpa_supplicant
eapol_version=2
ap_scan=1
fast_reauth=1
network={
    ssid="HomeWifi"
    bssid=12:43:1a:7d:52:6c
    proto=RSN
    priority=10
    psk="XXXXXXXX"
    }
network={
    ssid="HomeWifi"
    bssid=12:43:1a:7d:52:6b
    proto=RSN
    priority=5
    psk="XXXXXXXX"
    }
The proto has only RSN, and remove the key_mgmt line

In my case, I prioritize the 11a over the 11g, placing a weight of 10, but I define the 2 connections in case I stray too far from the base.
The second help in my case was to define this in the /etc/rc.conf:
Code: 
create_args_wlan0="country UY"
wlans_iwm0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP indoor -powersave"
ifconfig_wlan0_ipv6="inet6 accept_rtadv"
rtsold_enable="YES"

The indoor value enables me to use the extreme channels in 11a in my case

Try it
 
I just recently setup 13.2-RELEASE-p2 on a Thinkpad X1 Carbon 7th gen and was able to get the release to work with the new iwlwifi(4) driver using this snippit in /etc/rc.conf:

Code: 
kld_list="${kld_list} if_iwlwifi"
wlans_iwlwifi0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"
ifconfig_wlan0_ipv6="inet6 accept_rtadv"
rtsold_enable="YES"
 
A followup from my last post:
The wifi configuration does stall out after while. I can get it to restart by using service netif restart, but no spontaneous reboots or other stuff like that.
I am puzzling out how to make a more permanent fix. Any helpful clues from anyone?
 
OK, I installed wifimgr which made some changes to /etc/wpa_supplicant.conf and things got more stable. It looks much better now.
 
I had a similar experience as above (14.2).
Seems that with a mobile WiFi provider and this manually entered
/etc/wpa_supplicant.conf

network={
ssid="myId"
psk="myPsk"
}

the connection got up and working initially, but when the provider had a temporary short outage, I also got the "no carrier" in ifconfig output.

Installing and running wifimgr then gave this:

# /etc/wpa_supplicant.conf written by wifimgr(8)

network={
ssid="myId"
bssid=...
key_mgmt=WPA-PSK
proto=RSN
psk="myPsk"
}

and I experienced no issues after that.
 
Yesterday I did

pkg upgrade

on 14.2 on a ThinkPad T470s.

After this upgrade, I get "no carrier" in the ifconfig output as above. wifimgr no longer seems to help getting the connection back. The wpa_supplicant.conf file is unchanged compared with previous post.

Restarting didn't help either.
I did notice some suspect messages during startup.

iwmbtfw: iwmbt_fw_read: open: /use/local/share/iwmbt-firmware/ibt-12-16.sfi: No such file or directory
iwmbtfw: main: Firmware download failed!

Same error message as mentioned in

Thread 'Wireless network not coming up iwm0'

Hello there,

I had installed FreeBSD recently but I could only connect to one wireless access point of 2 that are available to me here. They are different as one is a standard WPA the other usually would take a browser login and uses HTCHAN WME. Doesn't seem to be any information in the handbook about how to use this latter type AP I did read the whole section on wireless networking but this is not mentioned. Anyways after a lot of fruitless trawling the web and because I had installed IA32 on 64bit machine I thought I'd reinstall and after working out (guessing) how to get the nice 80x24...

Sounds like I should try connecting by cable and then install iwmbt-firmware
Quite confusing, as the wifi did work for some hours after upgrade+restart...

Then:
Restarted the router, wifi working
Restarted laptop, wifi working
Installed iwmbt-firmware
Restarted laptop, the error message seems to have gone.

I'll have to see if problems reappear the next few days.
