At random times my devices suddenly fail to connect to Wifi on my ath0 =
device. Issueing /etc/rc.d/hostapd restart usually resolves the issue, =
but at some point that also hung.
Shutting down to single user mode in the hung state only partially =
succeeded, in the sense that ifconfig, hostapd and a few other =
network-related processes kept "running" - I assume the hangup of =
hostapd was caused by a hung process somewhere in that tree.
The system is:
uname -a
FreeBSD solfertje 10.2-PRERELEASE FreeBSD 10.2-PRERELEASE #19 r286718: =
Thu Aug 13 10:00:32 CEST 2015 =
dalroi@solfertje:/usr/obj/usr/src/sys/ANTELOPE amd64
It's quite possible that I've misconfigured something, so here's the =
relevant lines of my configs=E2=80=A6
rc.conf:
# Outside interface
ifconfig_fxp0=3D"DHCP"
ifconfig_fxp0_ipv6=3D"inet6 accept_rtadv"
# Wireless
wlans_ath0=3D"wlan0"
create_args_wlan0=3D"wlanmode hostap"
ifconfig_wlan0=3D"mode ng channel 9:ht/40"
ifconfig_wlan0_ipv6=3D"inet6 accept_rtadv"
# Bridged interfaces (see example at man 4 bridge)
cloned_interfaces=3D"bridge0"
ifconfig_bridge0=3D"addm em0 stp em0 addm wlan0 stp wlan0 up"
ifconfig_bridge0_alias0=3D"inet 10.236.150.1/24"
ifconfig_bridge0_ipv6_alias0=3D"inet6 fe80::6efd:b9ff:fe68:db36%bridge0"
# Internal wired ethernet (should that be above the bridge declaration?)
ifconfig_em0=3D"up"
ifconfig_em0_ipv6=3D"inet6 accept_rtadv"
hostapd_enable=3D"YES"
#=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
hostapd.conf:
interface=3Dwlan0
driver=3Dbsd
debug=3D1
ctrl_interface=3D/var/run/hostapd
ctrl_interface_group=3Dwheel
ssid=3Dfoo
country_code=3DNL
ieee80211d=3D1
hw_mode=3Dg
wpa=3D2
wpa_passphrase=3Dnonononono
wpa_key_mgmt=3DWPA-PSK
wpa_pairwise=3DCCMP
The ath0 device is:
pciconf -lv ath0 =20
ath0@pci0:5:6:0: class=3D0x028000 card=3D0x0300168c =
chip=3D0x002d168c rev=3D0x01 hdr=3D0x00
vendor =3D 'Atheros Communications Inc.'
device =3D 'AR9227 Wireless Network Adapter'
class =3D network
In case it's relevant: All connected devices get their IPv4 addresses =
through DHCP from this machine, the machine itself gets it's IPv4 =
external address from my upstream provider, the internal addresses are =
hardwired per interface. DHCP is configured to use hostnames (instead of =
IP's) that get looked up in Bind9 on the same machine.
Google did find some people on the internet with apparently the same =
problem, but nobody seems to have found (or posted) a resolution.
Am I doing something wrong? If not, is this a known issue? What's the =
next step?
