    Uh oh, looks like you missed this part of my earlier post -

    So it is a diagnostics script created and maintained by Forum member (a mod) Wild Man, which creates a detailed report about the overall wireless setup and related settings/configurations.

    Please follow the "Wireless Script" link in my signature and the linked post should be easy enough to follow. Post back the report (wireless-info.txt file or its contents) that the script generates.

    Re: Wired connection with 12.04 and Dell 1545

    Everything in the script report looks normal, except that it still can't scan networks. Let's see if going more verbose can give us some hint.

    But before that, try these quick shots first -

    1) If you have access to the router/access-point, log into its management interface and see if it has "WMM" support under "QoS" (may have to refer to its user manual). If there is, make sure it (WMM support) is disabled.

    2) If it supports N-channel, and it is enabled, try disabling it (set the router to b/g mode only).

    Both of these are known to cause problems sometimes, although those problem are connectivity related, not scanning failure. But if they couldn't help, they won't hurt either and are worth a shot.

    One more thing that I'd like to try with the driver itself is the following trick -
    Code:
    sudo modprobe -rv b43
    sudo modprobe -v b43 qos=0 btcoex=0
    This will be a temporary change that will be lost at next boot. If it helps scanning/connecting, we can make it permanent.

    If none of the above help, it's time for further investigation.., proceed as follows -

    Please do a reboot, make sure the wifi is enabled, then do -
    Code:
    sudo iwlist scan
    Let it try and fail.., then run these commands -
    Code:
    egrep 'net|wlan|b43|80211' /var/log/syslog > Desktop/syslog
    egrep 'net|wlan|b43|80211' /var/log/kern.log > Desktop/kern.log
    This will create two files "syslog" and "kern.log" on your desktop. Either attach these files, or better, upload their contents at http://pastebin.ubuntu.com/ and post the pastebin link in your next post.

    Also, let's see if the latest version of the sta driver is available from the repos, although it is less likely to help -
    Code:
    apt-cache show bcmwl* | grep Version

    Re: Wired connection with 12.04 and Dell 1545

    Right oh. Well, I had a look at the router setup and the QoS class in "0-WMM best effort default". When I tried to change it to "1-WMM background" I got the message "Rule name cannot be blank" and I don't know what I'm doing so I left it as it was.

    Then..

    [code]
    sudo modprobe -rv b43
    sudo modprobe -v b43 qos=0 btcoex=0
    [/code)

    Still couldn't connect wirelessly.

    I have pasted the sys and kern logs into "pastebin" under the name Panawe - haven't done this before, are they available?

    And finally...

    Code:
       annie@annie-Inspiron-1545:~$ sudo iwlist scan  
     [sudo] password for annie:  
     wlan0     Interface doesn't support scanning : Network is down  
     
    
     lo        Interface doesn't support scanning.  
     
    
     eth0      Interface doesn't support scanning.  
     
    
     annie@annie-Inspiron-1545:~$
    Phew, I'll be amazed if I did all that correctly!

    Okay, thought I'd done something wrong. Are these available?

    Re: Wired connection with 12.04 and Dell 1545

    Stop what you're doing! I'm connected. It transpires that security aspects of the wireless login were wrong (WEP vs WPA). I'm sorry to have caused you all this trouble and I'm amazed at your patience but for the moment (heartfelt prayers) it looks like I'm sorted. Wirlessly anyway, don't know about wrired.

    Thanks so much.

    Okay, not completely out of the woods yet.

    Have downloaded and installed the enormous update, rebooted and now can't find my wireless connection in Network manager!

    Help!

    Let's see the fresh report of the wireless_script then.

    And please remove the [Solved] prefix, since we are still in the struggle period (which is surprising to me, because this card/driver shouldn't be so hard to troubleshoot).

    Ah, yes. What I did was install Synaptic Package manager and tick the bcmwl-kernel-source package which I had previously been unable to load without losing my (wireless) internet connection. Wireless now rock solid.

    I still can't get the wired connection working but that's not important (unless there's a simple fix, otherwise I don't need it).

    Many thanks for your help - I think we're solved now so I'll leave the thread as solved unless you have any further suggestions?

    Thanks.

    Nope, no suggestions. Just a question -

    May I see the current version of the bcmwl driver you are using? Yours is one of the rare posts where I've seen this card (BCM4312) working 'solid' with the sta driver, so I may include this version as an alternative to b43.

    To see the package status and version -
    Code:
    dpkg -l | grep bcmwl
    Thanks for the feedback.
