    Re: 10.04 LTS & TP-Link TL-WN751ND Crashes System

    I followed your directions exactly (except for putting in the directory /me/home/Downloads) and there are some errors. I pasted them below:

    After rebooting the update manager appeared with a message about 12.04 LTS. Also a system error warning showed up in the form of a red "-" sign and when clicked on it displayed a message about a file system problem (or something similar - i forget now). The system offered a fix and opened the text terminal offering to remove a package, which it did.

    The wireless connection behaved the same as before this install, but I assume with the problems it wouldn't be updated and working correctly.

    What is the next step?

    Code:
     package architecture (i386) does not match system (amd64)...
     linux-headers-3.9.0-030900-generic depends on libc6 (>= 2.14); however:
     Version of libc6 on system is 2.11.1-0ubuntu7.12.
    You only need the amd64.deb and all.deb packages. Additionally, you need this one:
    http://security.ubuntu.com/ubuntu/po...10.2_amd64.deb
    Try it again. If errors occur, please show the outputs.

    Re: 10.04 LTS & TP-Link TL-WN751ND Crashes System

    all new problem..............

    i damaged my 10.04 installations and decided to try 12.04 and 13.04 because of their compatibility with the tp-link tl-wn751nd wireless card.

    i had the DVDs in a closet and tried them as live CDs. the problem is, neither will connect to my wireless network, though the old windows xp system connected perfectly.

    i ran LSPCI because its one of the few commands i know now:

    Re: 10.04 LTS & TP-Link TL-WN751ND Crashes System

    Now the card is on, try to setup a new wireless profile and check:
    Code:
    iwlist chan
    sudo iwlist scan
    cat /etc/resolv.conf
    route -n
    dmesg | grep ath

    i tried the above and the same pattern is repeating: the system tries to connect but after a period of time asks for a password. again, the system tries to connect but comes back again requesting a password. this can go on all day.

    right now i am using 12.10 live CD - no installation. maybe i can salvage the 10.04 installation that worked so well up until now. there are notices of broken dependencies and damaged packages to fix.

    about the tp-link tl-wn751nd PCI card, i've read some forum entries suggesting that it won't work with ubuntu. i'm sure i'm not the only one who has tried to use this card with ubuntu, but apparently it just won't work for some.

    right now i'm not sure which direction to go, but thank you for all of your help.

    Re: 10.04 LTS & TP-Link TL-WN751ND Crashes System

    First, I would try to install 12.04 LTS or 13.04 next to 10.04. Just give it a try
