I have finally got wireless connection. I am using wireless for a few days now and there are no problems.
I have tried a lot of things but Wicd seems to be the charm.
Here are the things I have done.
At first, I could not get connected with wires or without it.
Installing packages was a nighmare.
The error I get when configuring network from Yast is
“Unable to cofigure the network card because of kernel device(eth0, wlan0) is not present. This is mostly caused by missing firmware(for wlan0 devices). Check dmesg”
Dmesg shows: “cannot find firmware file 'intel-ucode /06-0f-od'.”
1. I had already blacklisted the ath5k drivers and downloaded madwifi.. This allows for editing the network in Yast. ( In Network settings, I get 2 cards one ethernet eth0 and the other ath0) I can edit both of them to do configuration. But I could not still get any network.
2.Then I tried updating the kernel as suggested by aus9 in post18.
3.I then installed Wicd. I installed wicd rpm one click package. I could see networks but no connection.
4.I thought it would be a good idea to get my broadband working with USB. There are a few good articles like
Then this clinched it.I found this http://en.opensuse.org/Huawei_UMTS_USB_Stick
Now got connected with 'umtsmon'.
5. Next step was to check dhcp and dhcpd. Find about about the wpa settings. Then I configured the WPA-PSK settings for wicd
6 . After logging out, I got connected to an internet site.
Thanks to everyone for their help and patience especially aus9.
