Question OpenSuse Wireless not detected


Hi guys !

I recently setup a new machine with OpenSUse 11 and all updates.. for the first 5 days, no problem using a wired or wifi connection... unfortunately, this morning, the KNetworkManager app stopped detecting wifi networks... The only way I can access the internet, is through a wired connection... I did a iwlist scan and the results is :
wlan0 Scan completed :
Cell 01 - Address: 00:1E:C7:84:BB:11
ESSID:"tuxnetwork"
Mode:Master
Channel:1
Frequency:2.412 GHz (Channel 1)
Quality=100/100 Signal level=-18 dBm Noise level=-127 dBm
Encryption keyn
Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 6 Mb/s; 9 Mb/s
11 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s
48 Mb/s; 54 Mb/s
Extra:tsf=00000001e43f0434
Cell 02 - Address: 00:17:9A:22:07:4E
ESSID:"rads"
Mode:Master
Channel:6
Frequency:2.437 GHz (Channel 6)
Quality=69/100 Signal level=-64 dBm Noise level=-127 dBm
Encryption keyn

48 Mb/s; 54 Mb/s
Extra:tsf=000000088edf7d3d
Apparently, the iwlist command detect both my own ESSID and my neighbor's wifi network... However, when I go to the KNetworkmanager, and I click New Connection, select wlan0, the ESSID list is simply empty... I had a connection until today that was working like a charm... What happened?? Thanks for help!

Hello,

Did you try using ifup to connect to the network? If you already know the password you can determine if your problem might be related to KnetworkManager. You can use KWifiManager to detect the network if needed.

Also, did you suspend the computer and have trouble after that?

Hi davesny!

I did ifup in a terminal as root, and this is what it gives:

ifup wlan0
Network interface is managed from NetworkManager
NetworkManager will be advised to set up wlan0
but it cannot be assured from here.

I also did ifstatus and :

ifstatus wlan0
Network interface is managed from NetworkManager
wlan0 is up
4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:1f:3b:7b:ba:e5 brd ff:ff:ff:ff:ff:ff

Man, I"m confused! maybe 10 years of windows washed my brain!! Please help !

THanks!!!

I managed to solve it... For some reasons, the Wifi card was set to "Never" activate in the Network Manager...(YasT/Network Devices/Edit/General tab).

If you want to use ifup wlan0 as root, you have to use ifup. Go to Yast, then select under the settings for the Network to use ifup. Make sure you configure the wireless conection there as well.

Please note that recovering from a suspend might be the cause. So make sure you are either rebooting or starting the computer.

Same problem

Hello,

sorry to revive this old thread, but I am getting this exactly same problem.

I am using OpenSUSE 11.1, and my notebook has a Broadcom BCM4312 wireless card. I installed successfully the broadcom-wl modules, and they are loaded properly.

When I run "iwlist eth1 scan", all the wifi networks are listed properly. However, KNetworkManager does not show me any available WiFi network at all. It's just a blank list.

I see lpallard managed to solve this problem, but I cannot find the setting he changed. There is no "YasT/Network Devices/Edit/General tab" here.

Anyway, does anybody have any idea what's going on?

Thank you

Trying to remember..

Zephon, I f remember correctly, I went to the Yast manager and then to the network devices, then I highlighted the network device that was not activating properly and clicked Edit, and then I saw on the General tab that the device, for some reasons was configured not to activate at all, which explained why I couldn't get access to it.

I am now using Slackware 12.2.... I hope you got it to work!

post again if it doesnt work.

Bye!

First of all, it will be helfpul to know what computer you are using.
Don't take for granted that the driver broadcom-wl for your Broadcom card is what will work. You might have to investigate a bit. You might have to install the broadcom-wl(kernel flavor) package in addition to that one. I have had some Broadcom cards that used the b43 or the b43-fwcutter packages.
Make sure that your setting in Yast, Network Settings, Your wireless card, the General tab are set to use Hotplug, and the firewall are set to the external zone.
You might try using ifup instead of Knetworkmanager, just in case there are some issues and/or conflicts with that. Use ping or kwifimanager if you want to see something when you test it.
As root use iwconfig to see what you have.
I hope this helps some!
