Thread: NetworkManager only shows VPN tab but no wireless or wired connections

  1. #1

    Default NetworkManager only shows VPN tab but no wireless or wired connections

    Hello,

    I remember that I did configure my desktop PC for wired and wireless connections since openSUSE 11.2, 11.3 and 11.4. Currently I have openSUSE11.4 x86_64 KDE. Today I happen to notice that the icon for NetworkManager in the taskbar has been replaced with a red X. I discovered that Network Manager only shows VPN tab, whereas Wired and Wireless tabs are greyed out. The strange thing is I still have Internet connection with the CAT5 cable being plugged in. I can still configure wired and wireless connections via YAST but I cannot fix Network Manager settings.

    Can you help me fix this problem? Thanks a lot!

    That normally indicates that you have switched to "ifup" mode in Yast network device settings. I guess it could also happen if the main NetworkManager process (the one started at bootup) has crashed.

    Hello nrickert,

    I switched to NM via YAST and got the wired and wireless tabs back. Phew! I had thought someone had tampered with my system!

    Anyway, now another problem arises: I got wired connection but no wireless. OK with Kwallet.

    NetworkManager keeps asking for password! I currently have NM 0.8.2-15.22.1 and plasmoid-networkmanagement 0.9.svn.1192577-7.2.

    KDE4.6.0

    openSUSE 11.4 kde x86_64 (for my desktop PC)

    kernel 2.6.37.6-0.5-default

    Is it asking for the KWallet password or the network key?
    Do you have a wireless network configured and set to auto-connect?

    I'm not sure if you are wanting to connect but something is failing, or you don't want to connect but are being asked for the key anyway.

    Hi,
    It's asking for the network key (passphrase). Anyway, this problem is resolved after I switched to NetworkManager Gnome and un-instaling plasmoid-networkmanagement based on a thread in this sub-forum. Now I got wired connection, but I still can't make wireless connection work. Somehow the wireless driver rt2860 and the module rt2860sta are not loaded properly or are corrupted.

    Is there anyway to debug or to cleanup the driver files before starting over?

    Yes, I do find that the gnome network manager applet seems more reliable.

    Hopefully, somebody more familiar with WiFi drivers can step in and help with your rt2860 problems.

    Try that last one, but using "/usr/sbin/rfkill"
    as in:
    /usr/sbin/rfkill list

    Hello everyone,

    I decided to download and compile the driver from Ralinktech's home page (the latest is still dated 2010/07/16), so I was able to establish wireless connection:

    Code:
    # /usr/sbin/iwconfig
    lo        no wireless extensions.
    
    eth0      no wireless extensions.

    Voila! PROBLEM SOLVED!
