Determining IP information for eth1... failed; no link present. Check cable?
 

Hi guys
i have check the internet for solutions and solved it..><
when i ifup wlan0, error msg
Determining IP information for wlan0... failed; no link present. Check cable?

using rhel
was able to connect to wireless few days ago.
wlan0 able to scan available network
Type=Wireless, ipv6init no, nm_controlled no

tried removed networkmanager
tried reinstall iwconfig, atheros driver.
tried stopped wpa_supplicant

any helps =(

Please correct me if am wrong, ifup wlan0 is supposed to bring up the wireless card, but the error you're giving has eth1 in it. you could try iwconfig for wireless..
Could you please post your ifconfig here.

Your heading says: So you try ifup eth1 if that's your NIC card or eth0, but we can determine that with the ifconfig results.

guys i did iwlist wlan0 scan
able to scan available wifi
i can iwconfig essid, or key, or channel with no error

the thing is when i use GUI i was able to connect

after i connected using gui
i type ifdown wlan0, the connection broken, and then immeadiate auto reconnect again

hi guys this is my wlan0

I'd sure like to help but I don't know what is going on.

"using rhel
was able to connect to wireless few days ago."

I'd say, what changed a few days ago? Some update, program addition? Motherboard issue, nic issue?

no, didnt changed anything at all
i using dualboot
my win7 windows update thats all
does it affect?

ok guys,i hv changed alot of setting since this problem
i have deleted wlan0,eth0 that in
/etc/sysconfig/network-scripts
/etc/sysconfig/networking/devices /profile

then recreated it with system-config-network,letting the system itself generate all the configuration of the wlan0
now the wlan is
the only thing i have changed in this configuration are
nm_controlled=no
type=wireless
thats it
the problem still presist
Determining IP information for wlan0... failed; no link present. Check cable?

any helps guy

bump =(

I got similar problem
I Replace NIC with new one, then it is working fine for me

but this shouldnt be a hardware issue right
since i am able to connect using NM

another thing is,
using iwlist wlan0 scan, i cant get available AP , this is only happen when i first created wlan0 using system-config-netw
then i enable NM and scan/connected. then i disable NM again..now the wlan0 is able to scan using iwlist

pls help
