Hi, I’m trying to get my wireless to work (openSUSE 11.1) in the house I’m staying in at the moment. I believe that the router config is ok because :
LAN works fine
my housemates have no problems with wireless (but they are using windows)
Basically, I installed the firmware using the script provided (install_bcm43xx_firmware), I can scan but when I’m trying to connect I don’t get any DHCP offers. DHCP works fine with LAN :
dhclient eth0 (works for LAN)
wmaster0: unknown hardware address type 801
wmaster0: unknown hardware address type 801
Listening on LPF/eth0/00:40:ca:df:18:10

dhclient wlan0 (but not for wireless)

DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 8
No DHCPOFFERS received.
No working leases in persistent database - sleeping.
I tried setting a static IP address (and even reserving it particular number on the router). But then I couldn’t connect to anything (even to the router itself).
What would be the next step in diagnosing this DHCP problem? Does the router write any logs about DHCP requests? Please help me out, if any more output would be helpful just let me know!
I’m 95% sure I entered the WEP key correctly. I’ll doublecheck when I get home. I’m using traditional ifup method, wpa_supplicant is installed but I’m not using it.
BTW : dmesg gives something like
wlan0 : associated
wlan0 : authenticated
does this mean that the WEP key is ok or is it still before this stage?

That should mean that the WEP key is OK.
Your next step may require looking at the actual traffic. If you can
run wireshark or kismet on another host, the resulting dump should help.
hi, you’re a star! NetworkManager gave me some progress. I can connect to the network and it sort of works but there are 2 problems :
it appears to be quite sluggish
it only works withing about 5m from the router.
dmesg output is as follows (that’s me starting next to the router and then walking to the next room and then coming back)
sorry for posting a lot of output but I’m trying to give as much info as possible!

There seems to be some USB dropouts there, is dongle loose?

If NetworkManager works and ifup does not, you had a configuration
problem with ifup.
I see from your dump that you have IPV6 enabled. Use YaST => Network
Devices => Network Services under the Global tab to turn it off.
With the device working, please run the command /usr/sbin/iwconfig and
post the output.
The BCM4318 does not have the best performance, but I find mine to be
usable. There have been some improvements in b43 and mac80211 since
2.6.27. You can try these by adding the repository

IPv6 is disabled in Network Devices (and I believe it was like that before as it has always caused lots of problems). What in the log suggests it’s on ?

I thought I saw a MAC address that was too long. On second look, it
came from the firewall.

You don’t want a Broadcom package. Those are for devices that are not
supported by b43 - you want compat-wireless-kmp-pae.
Actually, something weird is going on! It seemed to work perfectly fine yesterday evening and then this morning it keeps connecting and disconnecting. The log is a continuous stream of authentication, association, wlan0: beacon loss from AP XXXXXXXX - sending probe request and disassociation. After establishing a connection I can see one website and then it disconnects, NetworkManager keeps prompting for password as well. Does anyone know why ?
The detailed description is as follows:
It keeps disconnecting me. Sometimes it works fine for 5 mins, sometimes only for 5 seconds. the dmesg output is:

I tried googling it and apparently it is quite an old and well-known issue but I didn’t find any solution for it. Apparently killing NetworkManager helps but as described above I cannot connect via ifup (no dhcp offers received). The most annoying thing is that yesterday I had an hour long skype conversation and I thought it was working fine and then I tried to connect this morning and it just didn’t work at all…

It is something specific to your system. My 4318 connects immediately
and keeps its connection without ever dropping out. That is running
kernel 2.6.30, which has the same code as compat-wireless. That laptop
has very little memory, does not run X, and the network is managed
using ifup. The computer is 2 m from the AP and the network uses WPA2.
Unless you provide much more in the way of diagnostics, what can we do?
I am using WEP 128-bit and NetworkManager. ifup doesn’t work (dhcp doesn’t work - no dhcp offers, static ip address doesn’t work at all). Although DHCP works under network manager. Basically once the connection is established it is EITHER perfectly stable and I can use it for hours downloading lots of data and the dmesg looks like:

OR it disconnects me when I try to download anything and then it connects, etc. I’m oscillating between being connected and disconnected. dmesg looks like

If it’s working badly i just do rcnetwork restart and try again. Usually after 5-10 times I manage to establish a stable connection. The problem is that it takes lots of time and is very frustrating indeed…
Hi, I’ve got a new question for you. This is more of a pointing me in the right direction that actually telling me the answer.
When I’m trying to use ifup the problem is that i don’t get any DHCP offers. When managed by NetworkManager DHCP works fine. I’m trying to investigate what is the difference between the two situations. I’m running wireshark on another computer to get all the network traffic. Under NetworkManager DHCPDiscover is broadcasted normally and it works. I save the routing table. Then I switch to ifup. I bring up wlan0, it associates, authenticates, etc. Then I manually set the routing table exactly the same as under network manager. When I’m trying to ping 255.255.255.255 it recognizes it’s a broadcast. However, when I run dhclient wlan0 the signal is NOT seen on the network (according to wireshark). Is there any other place where I should look for some differences?
I would recheck the contents of /etc/sysconfig/network/ifcfg-wlan0.
Use ifcfg.template in that directory as the manual for the settings.
NM makes its own version of that info while ifup reads that one.
Hi, I’ve tried all these things before. And it just doesn’t work. So decided to take a more ‘intelligent-user approach’ rather than trying out different combinations.
I tried to set a static IP address and using wireshark I found that:
i receive some signals (e.g. router talking to the modem)
whatever i send (e.g. a ping or an ARP message) is seen by my wireshark but is not propagated to the network (i.e. wireshark on a different computer just doesn’t see it).
does that sound familiar?
