    My wifi doesn't work


    Hello all. I had (again) problems with my wi-fi connection both at work and at home. Although I usually I could connect after one or two reboots, this time, after five restarts, the adapter does not connect. This bored me.

    Currently I am connected with a Linux distribution, then I'll post the information on the network adapter that this distribution gives me:

    Code:

    It is a Linux issue, you need to go to a forum that deals with the Distro you are using. Broadcom chips have a big issue with the Linux Kernel no cooperating with them, so you have to use "Man in the Middle" software to get them to work. You are better off using either a Realtek or Intel chip Networking adapter.

    Do the following:

    Open a Elevated Command Prompt:

    Press WIN + X to open Start context menu.
    Select Command Prompt (Admin)​.

    Paste the following into the Command Prompt window, exactly as shown, including double quotes:

    cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & reg query "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" | find /i "proxy" >> postme.txt & notepad postme.txt & del postme.txt"

    and press ENTER.

    A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close. Post results in a reply here.

    Because that is how they are connected and it may be relevant to someone who actually wants to help.

    Unless there is an issue with IPTables on the machine that is running Linux, that is being used as a Gatway (ie Smoothwall, m0n0wall, pfSense), the OP needs to be asking about this in the associated Linux forum that is for the distro they are using.

    All routers run on some form of Linux. But the correct answers can not be given in a Windows forum. I have been using Linux off and on since 1997. But I still have to call up my brother about certain items that I run into, that you cannot find a clear enough answer online in the forums, etc.. Because not every person using Linux, will always have the same problem as another.

    Physical what Linux distro are you using? Are you using it as a Gateway instead of a router, or using it as an "Edge" router, behind another.

    If the second is the case, you need to ask in a Linux forum for that distro. There are certain items that can only be addressed in those forums. That is because you have people that also have a background in Unix on those forums, along with ones who work on the Kernel's.

    As I stated before. Broadcom Chipsets will not always work 100% with the Linux Kernel, because you have to use Ndiswrapper, along with the Windows WiFi adapter drivers. This should help about installing different drivers for your distro. Installing Broadcom Wireless Drivers - Ask Ubuntu

    Bro, what are you talking about? He is booted to Linux so he can post here about his problem with Windows, not Linux.

    Physical, your attachment isn't working, I get

    Click image for larger version

    Really need to see the Device Manager info as you are showing no connection at all, not even the default IP (169.254.x.x) used when no network is found.
