    Help getting WiFi and Wireless working at the same time

    I'm installing Ubuntu for the first time on my old Dell Inspiron 1505 and I was able to get the wireless to work with something I found on these forums, sudo apt-get install firmware-b43-installer b43-fwcutter, but after the restart my laptop won't connect to a wired connection and I'm not sure what to do. Additionally when I turn on WiFi it seems that I have to manually tell it to connect to the network each time even though I checked connect automatically, like if I turn WiFi off and turn it back on no networks are detected until I tell it to connect to a hidden network (but the network isn't hidden). I've tried reading through other threads about the wired connection issue, but I got a bit lost. I didn't see anything about the wireless issue though, maybe I missed something, but thats not a big deal as long as I know about it.

    The first thing people seem to check is $ ifconfig. Nothing like eth0 or eth1 shows up just lo and wlan.
    After that someone suggested sudo ifconfig eth0 up and I tried through eth4 with no results.
    The next thing it seemed that was suggested was lspci -nm, but I have no idea what any of that means.

    lspci -nm

    The first one above is your ethernet card that uses b44 driver, and the second one is the wireless card that uses b43 driver. The fact that your ethernet is not detected makes me suspect if you also have the proprietary driver "wl" installed for your wireless. It blacklists both b43 and b44 if is installed.

    Accordingly, please post the outputs of the following commands :
    Code:
    lspci -nnk | grep -iA2 net
    lsmod
    Please use 'Code' tags to post the outputs. Follow the "Using Code tags" link in my signature to see how to use it. Thanks!

    Re: Help getting WiFi and Wireless working at the same time

    Hmm.. no b44 in there, that's why ethernet doesn't work.

    There used to be a 'Who's first' fight over the ssb module between b43 and b44 ages ago. It seemed to have been fixed long ago, but I suspected the old rivalry has resurrected on your system. There was a simple workaround to make both happy, but let's first make sure it is what I suspect it is.

    Please do a fresh reboot (so that we have only fresh messages in dmesg), and post back the output of -
    Code:
    dmesg | egrep 'b43|b44|firm|ssb'
