Thread: Wireless stopped working ******** frustrated HELP *********

    Angry Wireless stopped working ******** frustrated HELP *********

    Hi there,

    I'm on dell vostro 1400 with openSUSE 11.0 and GNOME desktop. I had installed my original driver with install_bcm43xx_firmware and it had worked fine. i dont know what happened but it stopped working. The only change is that I remember is changing login ID to knight from kight. I have deleted the old connection. I retried putting different Keys to my WEP router security (64bit) and it does not work. When I start my computer it recognizes my home network and says that the signal strength is 80%. But when I open firefox, nothing happens. I loose wireless connection and get a PackageKit Error (cannot refresh cache whilst offline). It never reconnects.

    Here is some troubleshooting info.

    ifconfig gives me

    well he is using bcm43xx so presumably the broadcom card.

    what program were you originally using to connect? just knetworkmanager? have you checked to make sure your new user is in the 'dialout' group? does knetworkmanager say you are connected? if using wep, have you tried kinternet?

    There are several Broadcom cards - some work, some don't.

    looking at your ifconfig, I see the IP address assigned. Tells me, you have Wireless connected and looks good. Could be something u need to check on ur firefox. A proxy which doesnt exist??? Ping Google and see you can ping or atleast resolve hostname.

    Try connecting another pc on the network and see if u can browse OK. Check your router and see if it can connect your ADSl connection.

    do a route -rn and check if u have the default gateway set.

    I realize that it is likely a broadcom card; however, knowing the specific network card could point to a specific/known problem

    Is that reply for me or the OP?

    Anyway, as I was saying, some Broadcom devices do not work; not only that,
    they are not supported by b43. For instance, the only way to get BCM4310
    working in 10.3 is to use ndiswrapper. There is no way - as yet - to get it
    working in 11.0. Unfortunately, my fall-back position for my laptop is a
    plug-in Ralink card - which was once recommended hardware - and this only
    crawls along so I'm staying with 10.3 until a fix comes along.

    *************************************************************
    Another strange thing is that my ESSID keeps changing. My networkk name is 'home' and if you see my first post, it does show that. But now, ESSID is "". So, now iwconfig gives me

    wlan0 IEEE 802.11g ESSID:""

    Tx-Power=27 dBm

    Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
    Tx excessive retries:0 Invalid misc:0 Missed beacon:0
    ************************************************************
    About proxy settings: When I checked it my firefox properties, it said... "Use system proxy settings". I changed to "Auto detect proxy settings" and restarted the computer. Did not work.

    I also did ping Google and the reply was "unknown host"

    Doing a route -n gives me
    Kernel IP routing table
    Destination Gateway Genmask Flags Metric Ref Use Iface
    127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo

    and doing route -n with ETHERNET (wired) connected gives me

    Kernel IP routing table
    Destination Gateway Genmask Flags Metric Ref Use Iface
    192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
    127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
    0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0

    **************************************************************
    Another difference i notice is that now my wireless network is not detected when I start my computer as I had stated in my first post.

    Hopefully all this is enough for you guys to point me into a right direction.

    I forgot couple things
    I use GNOME with openSUSE 11.0 so I used YAST and then network settings (and this does say ESSID = 'home'). I also right click on the network symbol and edit network connections.

    I dont know how to check my user in 'dialout' group. How do I do that ? I also have never heard knetworkmanager and kinternet. Probably because I've never used GNOME ?
