Internet through WLAN - no ping to gateway

mikro · Oct 1, 2013

Hi,

I am trying to connect to the internet with a WNIC TP-Link WN321G, which is supported by ~~freeBSD~~ FreeBSD. There is already an internal connection on the PC via a LAN, so I have disabled it with ifconfig re0 down.

Code:

#ifconfig run0
run0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 2290
        ether f8:d1:11:1b:57:9f
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: IEEE 802.11 Wireless Ethernet autoselect (autoselect)

        status: no carrier

From a network-wireless guide I have done:

# ifconfig wlan0 create wlandev run0
# ifconfig wlan0 inet 192.168.3.44 netmask 255.255.255.0 ssid [myssidI] wepmode on weptxkey 1 wepkey 1:[password]

And there is no ping to host

Code:

# ping 192.168.3.1
PING 192.168.3.1 (192.168.3.1): 56 data bytes
ping: sendto: Host is down
ping: sendto: Host is down

Bringing up the interface with #service netif start shows the same error.

Hi Mikro.

As with all troubleshooting methods how do you know that the wireless hardware actually works?

See if it can scan for and find an access point:

# ifconfig wlan0 create wlandev run0
# ifconfig wlan0 up scan

Hi Johnbue, I have no clue if the HW works. Executing commands above shows me:

# ifconfig wlan0 create wlandev run0
# ifconfig wlan0 up scan
# ifconfig wlan0 up scan

The first AP is the one I am trying to connect

johnblue · Oct 2, 2013

Excellent. It works! Well, it at least can see some APs.

So you're trying to connect to the TP-LINK device. Is there any particular reason why you want it to have a static IP address? Will a DHCP assigned one suffice?

I ask because if you can get an easy DHCP assignment, then you will know that the wireless card can move traffic. After that, you can work on why the static fails.

Added to /etc/rc.conf:

Code:

wlans_run0="wlan0"
ifconfig_wlan0="DHCP"

Restarted machine.

After you associated with the wireless network you need to get an IP address.

dhclient wlan0

mikro · Oct 2, 2013

Code:

# dhclient wlan0
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 7
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 11
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 13
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 20
No DHCPOFFERS received.
No working leases in persistent database - sleeping.

dhclient succeeds on ethernet connecting.

SirDice · Oct 2, 2013

Are you sure the association worked? Are you using static or dynamic IP addresses? The interface must be associated and then assigned an IP address before you communicate.

I would also suggest ditching WEP. It's broken beyond repair. I can crack any WEP key in about 5 minutes. Use WPA-EAL at the very least.

mikro · Oct 2, 2013

It is already assosiated.in /etc/rc.conf:

Code:

wlans_run0="wlan0"
ifconfig_wlan0="DHCP"

#ifconfig wlan0 ssid myssid wepmode on wepkey mypassword

The software of the router is a little bit old, there is no other security option except WEP. It sucks, but the purpose is to test WLAN on FreeBSD.

Not really, those commands only show how the association is done, it doesn't show if it actually succeeded. As long as you have "status: no carrier" the association didn't work.

Assigned IP and netmask statically and it become associated

Code:

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether f8:d1:11:1b:57:9f
        inet 192.168.3.46 netmask 0xffffff00 broadcast 192.168.3.255

Glad that it is working for ya Mikro!

I am a bit lost though .. did you restructure your config commands? What did you need to do differently to get it working?

mikro · Oct 3, 2013

Hi, all I have done

/etc/rc.conf

Code:

wlans_run0="wlan0"
ifconfig_wlan0="DHCP"

#ifconfig wlan0 ssid myssid wepmode on wepkey mypassword
#ifconfig inet 192.168.3.34 netmast 255.255.255.0
#route add default 192.168.3.1

Yep, I do not need to assign the inet address dynamically and statically, but when statically - the interface becomes associated.

johnblue · Oct 3, 2013

ugh. Something is missing from somewhere on this.

Point me, please, what have I missed.

Hi all, WLAN works with another wireless NIC. The previous wireless NIC was a TP-Link WN321G v4 but only v1 is supported. Thanks all for help!

wblock@ · Oct 10, 2013

Good. Now, please stop using WEP. It is the wireless equivalent of having your password set to "password".
