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.

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?
