    Re: Netgear USB N150 wireless adapter keeps asking for password ubuntu 12.04

    I entered the commands and they just went to the next line with no errors. I rebooted and still have the same issue. The wireless just continually tries to connect and ask for the password over and over. Any other ideas?

    I rebooted and still have the same issue.
    When you reboot, these temporary changes are wiped out. Is there any change in performance if you execute the changes and DO NOT reboot? If so, we can amend a couple of files and make them persistent.

    Perfect.

    Ah yes there is a difference now. Right after entering <sudo modprobe -r rtl8192cu> the wireless from system settings> network disappears. Just ethernet now.

    Since you unloaded the possibly incorrect driver rtl8192cu, that's what we expected. Now what happens when you load the driver you carefully compiled:
    Code:
    sudo modprobe 8192cu
    Authentication requested [root] for install driver:
    install -p -m 644 8192cu.ko /lib/modules/3.2.0-27-generic-pae/kernel/drivers/net/wireless/
    /sbin/depmod -a 3.2.0-27-generic-pae

    jon@jon-desktop:~$ sudo modprobe 8192cu
    [sudo] password for jon:
    jon@jon-desktop:~$

    No difference. Wireless still won't show up or even try connecting in system settings > network

    Let's see if there are any messages that help us here:
    Code:
    sudo modprobe 8192cu
    dmesg | grep 8192
    Thanks.

    Re: Netgear USB N150 wireless adapter keeps asking for password ubuntu 12.04

    Hi. I'm a total noob in Ubuntu as well, and am having the same problem. I dual booted 12.04 on Macbook 8,1. After dealing with the Broadcom 43xx driver issue using the instructions at
    http://www.techlw.com/2012/06/macboo...ivers-for.html
    I now have the same problem as the original poster. The drivers work and my wireless card shows various wireless networks I can connect to. When I choose one, it just keeps asking me for the password and attempting to connect over and over.

    My apologies if I'm thread-jacking too much, but I think the solutions to our problems will be the same or similar (since the problems are similar). Instead of making a whole new thread for this issue, I'll just try to latch onto this one and see if we can't come up with a solution.

    Thanks.

    My apologies if I'm thread-jacking too much,
    I believe you are. I think the original posters issue, at this point is related to his driver, rtl8192cu. You have a Broadcom device which is unrelated.

    Thsi suggests that rtl8192cu didn't get unloaded correctly for whatever reason. Please try this:
    Code:
    sudo modprobe -r rtl8192cu
    Now check:
    Code:
    lsmod | grep -e rtl -e 80211
    Anything you find, please remove with:
    Code:
    sudo modprobe -r whatyoufound
    Check again:
    Code:
    lsmod | grep -e rtl -e 80211
    Keep going until there is nothing reported back when you check.

    Now load the newer driver:
    Code:
    sudo modprobe 8192cu
    Check:
    Code:
    dmesg | grep 8192
    Will it now connect? If so, we'll need to amend a couple of files.
