Wireless card missing in yast / network settings

The title pretty much explains the problem. The card itself is TP-LINK TL-WN722N (USB).

Here is lsusb info:

“iwlist scan” returns all networks in range.

The device is actually recognized and even works the way it’s supposed to with knetworkmanager or from it’s plasmoid version. The problem is I can’t get it to work in YAST(ifup). Probably will be able to manually do this from terminal but really want to go with yast.
I find knetworkmanager(ot plasmoid) both to suffer from some crashes in certain conditions and want to get rid of them.

When I try to add manually the card in yast I can’t seem to be able to get it to work. For “name” I use wlan0, for “type” - wireless, then check the “usb” option. Then just the normal dhcp, ssid, wpa2 stuff. But after I apply the changes the card seems to be not working. I have a wired card listed in yast/network settings and after comparing the settings between the two I found MAC and BusID fields in the “overview tab” missing for the wireless card. The other thing is when I try to manually specify the ath9k_htc module to be used nothing happens and the field remains blank. The module itself is loaded.

Probably these things have something to do with the whole story.

I had some IRQ problems with the system, but i believe I managed to fix them already.

Any help will be appreciated.

Please post the contents of /etc/sysconfig/network/ifcfg-eth0 and
/etc/sysconfig/network/ifcfg-wlan0.

Your problem may be that eth0 is starting “onboot”. With that setting, you will
NEVER get wlan0 to connect.

You were right on it. Preventing my wired card to start at boot time worked like a charm and now wireless is working. Thanks. Any additional info on why that’s the case? Sounds strange to me.

And something else interesting I’ve noticed in /var/log/messages log:

Is this behavior normal? It was pretty much the same when I was using wired connection.

The rule for ifup is to used the wired connection if it is available. That has
been true in openSUSE for a long time.

Are you using DHCP for DNS, or are you doing something else?

I’m using DHCP and actually don’t know how(if possible at all) to “set up manually” DNS and use DHCP for everything else.

Router LAN IP is 192.168.1.1 and the mask is 255.255.255.0.
Here are the settings I have for DHCP on the router (TP-Link TL-WR1043ND):


Start IP Address: 192.168.1.100
End IP Address: 192.168.1.110
Address Lease Time: 	120
Default Gateway: 192.168.1.1	
Default Domain: left blank	
Primary DNS: 10.5.0.1
Secondary DNS: left blank

I have reserved the 192.168.1.101 address permanently for my wireless card(specified by it’s MAC).

On the WAN side of the router I have statically set settings:


IP Address:  some IP address
Subnet Mask: 255.255.0.0
Default Gateway: 10.5.0.1
MTU Size (in bytes): 1500
Primary DNS: 10.5.0.1
Secondary DNS:  blank

Here is /etc/hosts. I’ve disabled IPv6

#
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.
# Syntax:
#    
# IP-Address  Full-Qualified-Hostname  Short-Hostname

127.0.0.1       localhost

/etc/resolv.conf file:

### Please remove (at least) this line when you modify the file!
nameserver 10.5.0.1

Current hostname is set to sda-linux, domainname is blank(domainname command result).

Anything wrong in the whole setup? Thanks.

I do not see anything wrong. As it is working, ignore the messages. That “Always
