Not getting the hang of wireless....

English Network/Internet
#1

So far I’m liking openSuse a lot. But I guess I am just not catching on to the flow of things. I’ve spent most of a day looking for how-too info that does not presume I already know how too. Any suggestions for a bone-head start on what does what, and where I find it? my hot topic right now is getting my wlan card working. I think I have the latest firmware file, and I ran the German script, but it does not tell ME much (hoping it means more to someone here…
Thanks in advance
David

!!! CND0120E: Network card wlan0 has no IP address
!!! CND0380E: No WLANs detected on interface wlan0. Hardware and/or driver not configured properly
!!! CND0230W: IPV6 enabled
!!! CND0240E: knetworkmanager for network configuration enabled but a YAST network card configuration for wlan0,eth0 exist

The wlan0 is not finding a dhcp server to get an ip address and you need to configure your wireless access point - set it up to give an dhcp address .
Click on the network icon in the toolbar and see if you have any networks listed. You then need to enter the passphrase/key for the network.

Without firmware, no chance for wireless.

Search the web for the missing file, taking a look at the realtek homepage for your device is also a good idea, maybe you don’t need the drivers they provide, but normally their driver packages contain firmware images, too.

#4

I did get the firmware file, but not sure where it needs to go. I thought I had put it in RTL8192SU/rtl8192sfw.bin but looking at many other suggestions, it looks like it should go in Root/lib/firmware/RTL8192SU/rtl8192sfw.bin
or perhaps Root/lib/firmware/RTL819xU/rtl8192sfw.bin ?
but either way, I can not seem to get anything to go in Root/lib/anything…

It should be in /lib/firmware/RTL8192SU/rtl8192sfw.bin. FYI, in any form
of *NIX, a bare slash (/) is the ROOT of all file systems. Unlike
systems from Redmond, there is no A:, B:, etc. Every file known to the
system has a direct path back to /, whether it is local or on an NFS
server a continent away.

To get the file where it needs to be, change your working directory to
the one where rtl8192sfw.bin now resides, and enter the commands:

sudo mkdir -p /lib/firmware/RTL8192SU
sudo cp -v rtl8192sfw.bin /lib/firmware/RTL8192SU/.

Remember, case is important. I carefully entered them the way you wrote
them. I hope ‘dmesg | grep firmware’ lists then that way. In
addition, the last character in the cp line is a period (.). It must be
there.

#6

Thank you greatly. That seems to have worked like a charm. Guess I’ve more than a little sudy to do to get this system figured out.
Thanks again.

#7

And if you would tell us, where exactly you got it from, other users with the same problem might also benefit from this thread.

#8

Ok, spoke too soon. The unit will connect and runs just fine… for about 5 min. Then it looses connection and can not seem to get past the password phase from that point on unless I either power down the computer for 5 min or reboot my wireless router. Seems odd. Any ideas?

The firmware files came on a disk with the wireless card. I’d be happy to post them if that would be usefull. I also emailed the company, sabrent, and was given three places to download from, but have not as yet done so.
