Help for setting up Wireless connection

[kulket]

Hi,

I installed OpenSuse 11.1 recently & been trying to setup wireless. I have gone through the primer "Getting Your Wireless to Work".

Based on that, here are the details:

I have BCM4311 as the pci wireless device:

1. #lspci
0b:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

2.# /sbin/lspci -n
03:00.0 0200: 14e4:170c (rev 02)
0b:00.0 0280: 14e4:4311 (rev 01)

3. # iwfconfig
wlan0 IEEE 802.11bg ESSID:""
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=0 dBm
Retry min limit:7 RTS thrff Fragment thr=2352 B
Encryption keyff
Power Managementff
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

4. I see I am missing ESSID & access point is missing. How do I set up those ? When I do 'iwlist scan' I get following message:

wlan0 Interface doesn't support scanning : Network is down

I have tried putting my home wireless n/w name in the YAST network manager, however still I cannot scan/see any wireless networks.

Can Someone please help me with setting wireless connection ?

Regards,
kulket

try using Yast - Network and deselect []Manage by Networkmanager. Make sure ipv6 is disabled and configure your essid and key through Yast and with luck you will be up. I make this loose assumption since it appears to recognize your wifi but without the needed configs

it's a starting point...

Have you installed the firmware? Please post the output of

dmesg | grep b43

Are you trying to use NetworkManager or ifup?

[kulket]

First ofall thanks to Larry & 'techwiz03' for trying to help me.
Based on the primer/stickies I have been able to make a little progress.

Yes I have installed the firmware. When I had installed it I remember recieving output after dmesg | grep b43.
However, if I doit now, I get nothing.

# dmesg | grep -i broadcom
ndiswrapper: driver bcmwl5 (Broadcom,10/12/2006, 4.100.15.5) loaded
eth0: Broadcom 44xx/47xx 10/100BaseT Ethernet 00:15:c5:b1:5c:d3


Now I when I do iwlist scan I can see my network along with the other networks. However, I cannot connect to it.

Cell 02 - Address: 00:1CF:BC:FC:75
ESSID:"MySSID"
Protocol:IEEE 802.11g

12 Mb/s; 24 Mb/s; 36 Mb/s; 9 Mb/s; 18 Mb/s
48 Mb/s; 54 Mb/s
Extra:bcn_int=100 Extra:atim=0
IE: WPA Version 1
Group Cipher : TKIP
Pairwise Ciphers (2) : TKIP CCMP
Authentication Suites (1) : PSK


I have tried connecting to it using YAST-Network manager and also ifup. Both ways I see its trying to connect to my wirless network, but fails.

Please let me know if I need to provide any output/info. I have
dual-boot system, with Dell 1390 WLAN card.

As I do ifconfig, here is what I get:

#ifconfig
wlan0 Link encap:Ethernet HWaddr 00:18:F3:49:EE:6A

This seems to be a common problem.

Please go here. This is a fix for most dell wireless modules. Hopes this helps

Caf, can we have a sticky for that in the wireless section?

You get no output from 'dmesg | grep b43' because you don't have b43
loaded - you are using ndiswrapper. The two are mutually incompatible.

You also have a problem with your BCM44xx. It needs the driver ssb,
which will grab the wireless device and may prevent proper loading of
ndiswrapper.

Your first post said that you have a BCM4311. Why are you using
ndiswrapper? You do know that that approach runs a Windows driver in
the innermost level. Furthermore, the BCM4311 works very well with b43.

Although I am not a newbie to Linux, I am a novice when it comes to networking/wireless. Thanks all for your help.

Larry, from the link posted above, I found your reply to similar questions: I am gonna install b43 firmware again & activate it.

/usr/sbin/install_bcm43xx_firmware
/sbin/modprobe -rv b43
/sbin/modprobe -v b43

What should I do about BCM44xx which needs ssb currently ?
Also, should I uninstall ndiswrapper ?

Nothing, if you do this:

As Akeollh said, do not worry about BCM44xx. The driver ssb was
created so that a single copy could be shared between 44xx and 43xx
devices. It will work without any difficulty as long as you get rid of
ndiswrapper.
