    Wired connection slow to be established & wireless gone

    Hi,

    I am running Maverick on my desktop pc.

    Code:
    uname -r
    2.6.35-22-generic
    Following recent update to kernel 2.6.35-22-generic, wired connection seems to take forever to be established (Network Manager icon keeps swirling for a long time, until I hit the Firefox icon then I got Internet). NM does not show wireless connection as active at all. Then after I pull the cable and restart, I don't get wireless connection even after I blacklisted rt2x00usb, rt2x00pci and rt2800pci. My wireless adapter is Trendnet TEW-642PCI (?) which uses Ralink's rt2860sta driver. By the way, both wired and wireless connections use auto DHCP.

    Code:
    lspci -v

    How should I remedy the wired and wireless problems?

    Thanks a lot for your help.

    Hi,

    I uninstalled network-manager and network-manager-gnome, then installed wicd. The later seems to have a better user interface, it also gave me a wireless interface with signal strength and SSID, etc., however it kept giving me "bad password" error thus I couldn't connect wirelessly; I found out later that this is because for some unknown reason network-manager and related dependencies were not completely removed. Anyway I uninstalled wicd then failed to re-install network manager. I ended up having to re-install Meerkat!

    Just a word of warning to those users who attempt to install wicd.

    When removing an application, use the purge option eg:

    Code:
    sudo apt-get purge network-manager-gnome
    Or select Complete Removal in synaptic. I'm not sure what the Software Center does when you click the remove button.

    Thank you cariboo907 for the tip on using the purge option. I always select "Complete Removal" when using Synaptic.

    Hi,

    I re-installed Meerkat and during installation phase put grub boot loader in its own root partition. Then I went inside openSUSE 11.3's /boot/grub/menu.lst to add the following so that I can boot into Ubuntu from openSUSE's main menu regardless whether Ubuntu's kernel is updated:

    Code:
    title Ubuntu Meerkat 10.10 Beta booting via symlinks
    root (hd1,8)
    kernel /vmlinuz root=/dev/sdb9 ro quiet splash
    initrd /initrd.img
    boot
    Next step will be to set up wireless connection.

    Cheers!

    Just as a point of interest, I had a harder time getting my D-Link WUSB-1340 working in openSUSE than I did in Maverick and Fedora, as it needed to download and install some firmware before the device would work. With Maverick and Fedora it worked out of the box.

    Grub2 does the same thing as you did automagically when it was installed. The only entry I had hand edit was for PCLOS.
