 Posted: Sun Apr 08, 2012 11:32 am Post subject: lenovo x121e (intel) / no ip traffic via wlan0 [solved] |
 |
|
hello community,
i am not able to have ip traffic via my wlan interface.
i have a lenovo x121e (intel version). i am still using kernel 3.0.6. so far i have configured wlan. the interface is working so far. i can connect to my AP and can scan other wlans but i am not able to ping to a system in my network. i have no firewall running on my AP or on my laptop.
some details.
ifconfig output for wlan0
| Code: |
wlan0 Link encap:Ethernet HWaddr 74:e5:0b:23:e6:4e

the routing table
| Code: |
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
0.0.0.0 192.168.10.1 0.0.0.0 UG 0 0 0 wlan0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0
|
rc-update show that no eth0 is used.
| Code: |
mtab | boot
net.eth0 |
net.lo | boot
net.wlan0 | default
netmount | default
|
my resolv.conf
| Code: |
# Generated by net-scripts for interface wlan0
nameserver 192.168.10.10
|
part of the conf.d/net
| Code: |
modules="wpa_supplicant"
wpa_supplicant_wlan0="-Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf"
wpa_timeout_wlan0=60
config_wlan0="192.168.10.19 netmask 255.255.255.0 brd 192.168.0.255"
routes_wlan0="default via 192.168.10.1"
dns_servers_wlan0=( "192.168.10.10" )
|
the wpa_supplicant.conf file
| Code: |
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=2
network={
ssid="<SSID>"
psk="<WPA2KEY>"
key_mgmt=WPA-PSK
priority=5
}
|
wpa_cli tells me that my wlan0 interface is running and has an ip address.
| Code: |
Selected interface 'wlan0'
bssid=00:1b:63:22:3b:49
ssid=<SSID>
id=0
mode=station
pairwise_cipher=CCMP
group_cipher=CCMP
key_mgmt=WPA2-PSK
wpa_state=COMPLETED
ip_address=192.168.10.19
|
some output from dmesg where i can see that wlan0 is associated with my AP
| Code: |
[ 12.489859] wlan0: authenticate with 00:1b:63:22:3b:49 (try 2)
[ 12.492650] wlan0: authenticated

[ 304.297884] kworker/u:0 used greatest stack depth: 3496 bytes left
|
when i use the eth0 interface instead of wlan0 all works fine.
maybe it is something trivial but at the moment i do not see it  someone please has an idea?
best regards

Can you ping the router?
If so, then the fact that you can't ping other systems on your private network seems more likely to be caused by the router, not your NIC.
Have you tried other wireless networks?

hello hypnos,
no i can not ping the router.
i was using this notebook with another wlan but at that time i had installed opensuse 11.3 with a kernel 3.x.
the router is an apple airport express with 802.11g. in the admin gui from this router i can see that my notebook is connected.
regards

hello community,
as i have written before it must be something trivial. i have checked the config of the router. i saw that it was not working in bridge mode. after changing the config so the router is acting in bridge mode the ip traffic is working as expected.
