    wifi connected but no internet

    I bought a new laptop Asus X155LA with windows10 preinstalled. I installed Ubuntu 16.04 as dual-boot.
    The install was successful except that I have no internet. Ubuntu announces at start up that I am connected to my router, but there is no internet.
    Moving the laptop nearer to the router does no good. Internet is fine on Windows10. It was also fine on my old laptop with Ubuntu 13.04.
    Any help greatly appreciated, thanks

    Re: wifi connected but no internet

    Can you ping the router by IP?
    Can you ping 8.8.8.8?
    Can you ping google.com?

    Do each in that order and report where the failure happens, please.

    There is also a wireless-info script mentioned all over the place in these forums. Get it. Run it. Post the link it can create so others can review the data. Think it is on github, so look for it there with google.

    Re: wifi connected but no internet

    Hello, go to the link below and download the new driver zip file to your desktop then right click on the file and click extract here.
    https://github.com/lwfinger/rtlwifi_...ock.new_btcoex

    Make sure secure boot is turned off in the bios before you try to install the driver if you have secure boot and it must stay off, otherwise just install the driver.
    Code:
    cd rtlwifi_new-rock.new_btcoex
    make
    sudo make install
    sudo modprobe -rv rtl8723ae
    sudo modprobe -v rtl8723ae ant_sel=2
    We may have to change a parameter or two, it looks like you have done a couple on your own.
    Thanks

    Re: wifi connected but no internet

    Thankyou Wildemann, that worked a treat.
    Should I re-enable secure boot? (I don't know what secure boot is??!!)

    Thanks once again.

    No, if you re-enable secure boot the driver will stop loading.

    Unfortunately the same problem occurs after updating.

    Re: wifi connected but no internet

    If the driver file was replaced, then the driver you downloaded could be gone. Get it from github again and install. If that fixes it, great!

    May want to blacklist/freeze that specific package so it doesn't get updated. However, that means when it is fixed finally, you won't get those too. I'd check every month whether the packaged version is newer than the github version that you have installed. A reoccurring reminder in a calendar, perhaps?

    OTOH, if that doesn't fix it ... probably rerun the wireless-info script and post here again. I dunno.

    Re: wifi connected but no internet

    Whenever Update Manager installs a newer kernel version, you must recompile the driver:
    Code:
    cd rtlwifi_new-rock.new_btcoex
    make clean
    make
    sudo make install
    reboot then your should have wifi again.
    I am sorry I should have included this part of the directions I must have gotten distracted by something.
