The notation of phy refers to the “Physical Layer” on the connection.
The notations for eth0, etc. are the devices. With Linux wireless
networking using mac80211 for the MAC (Media Access Control) layer, a
large number of pseudo-phy layers can be created, which is why you get
it printed.
Can you scan for Access Points? You use the command ‘sudo
/usr/sbin/iwlist wlan0 scan’ for that. Does your computer have a
switch that turns the radio off? If so, is it on?
i am having a similar problem because i cant make my wireless adapter work. here is my info. (i have already tried a lot of ideas and forum tutorials)
this is what i get when i run the network settings application =
BCM94311MCG wlan mini-PCI (Not connected)
MAC : 00:1a:73:ce:e6:60
• Device Name: wlan0
• Started automatically at boot
• IP address assigned using DHCP
this is what i get when i type this into terminal =
gonzalo@linux-kynm:~> /usr/sbin/iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wmaster0 no wireless extensions.
wlan0 IEEE 802.11g ESSID:""
Mode:Managed Channel:0 Access Point: Not-Associated

gonzalo@linux-kynm:~> sudo /usr/sbin/iwlist scan
lo Interface doesn’t support scanning.
eth0 Interface doesn’t support scanning.
wmaster0 Interface doesn’t support scanning.
wlan0 Interface doesn’t support scanning : Network is down
i dont know what else to do. Please help.
it seems that i am very close to getting it to work, because suse recognizes the existance of the wifi card, but it is not activated
or connected. What could be the problem?

You have not configured it. You need to decide if you want the
traditional “ifup” control, or if you want to let NetworkManager
control the device. That choice is made with YaST. Once that decision
is made, you need to do the configuration with YaST or with the NM applet.
You need to start YaST, select Network Devices / Network Settings and
edit the parameters. The choice between ifup and NM is on the Global
Options tab.

Did you compare what you entered with what I told you to do?

Your path does not include /usr/sbin, which is why the naked iwlist
was not found. To see how to use iwlist, enter ‘man iwlist’.

how do i edit the parameters?
i tried the other way and it did not work either. (traditional)
The network manager does not connect, even if i try adding or deleting
another connection in the NM.
I still get the same error message. what do i have to write in the parameters?

Well, you could edit the file /etc/sysconfig/ifcfg-wlan0, or you can
fill out ALL the screens in the YaST section I told you about when
you edit the setup for your wireless.
When you get the command the way I wrote it, do you see any APs in the
iwlist output?
i did not understand how is it that you want me to config that file. Please show me how.
also when you mean all the screens what screens do you mean?
when you ask me about aps in the iwlist, i just did not know where to start with that one.
it seems i am not going anywhere with this wireless business.
also i am having trouble finding a suitable temperature monitoring program. and on top of it all the xchat and other irc programs aint collaborating either.
here it is =
gonzalo@linux-kynm:~> sudo /usr/sbin/iwlist wlan0 scan
wlan0 Interface doesn’t support scanning : Network is down
gonzalo@linux-kynm:~> dmesg | grep b43
b43-phy0: Broadcom 4311 WLAN found

If you have network access while running Linux, run the following command
sudo /usr/sbin/install_bcm43xx_firmware
That should take care of your problem. As noted above, you have not
installed firmware, which is why your wireless is not working. If you
want to know why you need to install the firmware, google with
“Broadcom firmware” as your search terms and read some of the hits.
If you do not have network access in Linux, then go to the “Additional
Wireless Bits” sticky in this forum to learn what to do.
it just did that sudo command and restarted my laptop and it worked awesome.
i am glad you are such a master at this stuff.
now i need to go to other parts of this forum to seek help on the other stuff that is not presently working like the irc chat, and the sensor program to know what temperature my hard drive has. and how to listen to radio online, because banshee aint cutting it. etc.
hope i can make all these stuff work, but you have already helped me with the most important problem of all, my wireless adapter.

That file is created when you edit the interface parameters with YaST.
Are you sure that everything is OK with firmware, etc. You need to
look carefully at the output that results from the command ‘dmesg’.
