Solved Ifconfig: wlandev: bad value

F

Fbsdnew

Attempting to set up Hostap mode very simply like how the instructions in the handbook suggest. When I issue the command (ifconfig wlan0 create wlandev ath0) it returns with (ifconfig: wlandev: bad value)
This is something not mentioned in the handbook or in these forums or anywhere else I have searched. Please help FBSD community!
 
So the value of the variable wlandev is bad? Do you have a device called ath0?
Try ifconfig ath0.

Quoting from ifconfig()
The following parameters are specific to cloning IEEE 802.11 wireless
interfaces with the create request:

wlandev device

ath is a network driver for Atheros network interfaces.

Do you have anything else in ifconfig? Maybe some other card? If not, you'd need to load the driver for your network card. 11.5. Setting Up Network Interface Cards - FreeBSD

I am not sure how to tell if I have a network interface card setup with ifconfig. I dont think think that I do. could you tell me based on my ifconfig output. I see that there are instructions on how to setup this card but are there instructions on how to tell which card I have or driver I need to load?

I see only re0, which is ethernet.

You need to load the driver for your wireless card. To see your card, try usbconfig. Or pciconf -lv and look for a card that has class=0x028000, or says WiFi.
 
Following the handbook at example 31.3 I find myself in a similar situation after replacing the ethernet interfaces' MAC with that of the wireles interface by
# ifconfig em0 ether 00:28:f8:48:80:28
Thereafter I am stuck with:
# ifconfig wlan0 create wlandev iwm0 regdomain ETSI country CH ssid MYSSID up
ifconfig: wlandev: bad value

Could any one guide me through this Failover mode example?

This is on 12.2-STABLE r367519 GENERIC amd64 and with:
# pciconf -lv | grep 0x028000

wlandev is meant as a variable. In your case it is iwm0.
I have that in /etc/rc.conf to setup the lagg(4) interface:
Code: 
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA"
create_args_wlan0="country DE regdomain none"
ifconfig_lagg0="up laggproto failover laggport em0 laggport wlan0 DHCP"
May be it can be simplified to less lines.
 
I have tried how to bring up my wlan from the console. The procedure below worked. The difference to your command is the missing trailing up. Authmode and others seem to be configured elsewhere by wpa_supplicant or so. In the past I have just used the configuration in /etc/rc.conf. Finally most people will do so. Nevertheless may be some expert will correct me if I am wrong;-).

ifconfig wlan0 create wlandev iwn0 regdomain ETSI country DE ssid Wellensalat
