    Persistent wireless authentication issue

    Hi!
    I'm a very new to these forums, and quite new to Linux itself really, so any help from experienced users would help me a lot .

    I have a Dell Inspiron 1545 laptop computer running the latest version of LXLE. In the last few days I have gone through Ubuntu 14.04 and Ubuntu 16.04 as well as LXLE trying to solve my issue, but since all three of the operating systems are based upon one another, the issue persists.

    The issue in question is that whenever I try to connect to a wireless network, it will, of course, require authentication in the form of a password or encryption key. But when I enter the correct password, the computer will take about a half a minute to try and connect, fail, and ask for authentication again. This same issue has persisted through all three OSs, even after installing drivers for my wireless card.

    The network controller for my laptop is a BroadCom Corporation BCM4312.
    I have no issues connecting via ethernet cable or a tethered USB device, in this case my Samsung Note 5.

    I'm aware I'm likely leaving a lot of vital information out of this post, simply because I do not know what needs to be posted to solve the issue. If anyone knows how to fix this problem and needs me to post more information, just let me know and I will. I'm at my wits end with this issue. Thanks!

    P.S. Yes, my wireless hardware switch is on. My computer recognizes all surrounding wireless networks, but fails to connect to any of them.

    P.P.S. Preferably I would like for the solution to be pertinent to Ubuntu 16.04, but if there are any solutions for any of the three OSs, I will be happy with any one

    Click on the wireless script in my signature and follow the directions for running it and posting the link created to pastebin here.

    Thanks wildmanne39 for the guidance!
    Here's the pastebin link: http://paste.ubuntu.com/24427707/

    I also followed the instructions found in "[SOLVED] How to install a driver for the Broadcom series of PCI wireless cards", and after locating and attempting to install the proper driver for my [14e4:4315] (rev 01) pci.id, the terminal informed me that I already had the driver and that it was already updated, yet of course the issue remains.

    Re: Persistent wireless authentication issue

    Is this the network you are trying to connect too JacobsWifi ? this is the firmware you installed firmware-b43-installer?
    Thanks

    Re: Persistent wireless authentication issue

    Correct, I am trying to connect to JacobsWifi, and firmware-b43-installer is the one that I tried to install from the Broadcom driver list, and found to already be installed and up-to-date.

    (Thank you for working with me, I'm sure its tedious having to ask these questions that I should've already stated in the question itself)

    Re: Persistent wireless authentication issue

    No problem, no one starts out knowing any of this stuff.

    Please go into network manager and set your settings to match the screenshots.

    We may have to try the other driver but this is the one that should work the best.

    Please do:
    Code:
    sudo cat /var/log/syslog | grep -e b43 -e firmware -e wpa -e wlan -e etwork | tail -n25
    Make sure that all ethernet connections are unplugged first, because they will over ride your wifi connection.

    Thanks

    Re: Persistent wireless authentication issue

    After changing my network settings to match the screenshots, disconnecting my ethernet cable, and running the cat command, I tried to connect to my wifi network, and the same problem persisted.

    Here are the results of the cat command, for reference.

    It is also worth noting that prior to this post I was using LXLE, but I wiped and performed a fresh install of Ubuntu 14.04 to a) better match the screenshots and b) see if maybe it would work after following your previous tips (unfortunately it did not). Should I upgrade to Ubuntu 16.04 and then try again? Or do I need to do something else entirely?

    Re: Persistent wireless authentication issue

    So after you ran the command to post that output you installed 14.04? that output was to help me see what is wrong and if you changed Ubuntu's then it is not going to be the same.

    I believe you need to install different firmware in 14.04, please post the output from the OS you are using now and the command I gave you to run.
    Thanks

    Re: Persistent wireless authentication issue

    Sorry, I worded that poorly. The output I posted is correct, I installed Ubuntu first and then ran the commands you told me to. The output is for my current OS (Ubuntu 14.04), not the previous one.
