    Re: Wifi not connecting in Ubuntu 17.04 Beta

    The OP has a network manager bug and a bug that shows his device as two different devices, I recommend filing a bug report.

    I have found a fix that has been reported here to bugzilla.
    https://bugzilla.gnome.org/show_bug.cgi?id=780119

    Open
    /etc/NetworkManager/NetworkManager.conf

    add lines
    [device]
    wifi.scan-rand-mac-address=0

    This got me connected again.

    That worked for me too. Not really sure what that code does as I'm relatively new to Ubuntu, but thank you.

    Kernel 4.10 doesn't play nicely with the Realtek adapter in my HP Stream 11. Wifi connects, then stalls in Firefox. Oddly enough, I'm able to download updates via the terminal. Unfortunately, kernel 4.4 in 16.04 doesn't support my Stream well, so 16.10 is the only option for me.

    If the Realtek wifi is an rtl8723be, the ant_sel parameter of the module is important with the newer HP laptops

    Re: Wifi not connecting in Ubuntu 17.04 Beta

    I upgraded from 16.10 to 17.04 today and I do also have the same problem but just with one of my wifi adapters.

    This adapter does not allow me to connect:
    Code:
    Bus 001 Device 066: ID 148f:3572 Ralink Technology, Corp. RT3572 Wireless Adapter
    and

    Code:
    rt2800usb              28672  0
    rt2x00usb              20480  1 rt2800usb
    rt2800lib              94208  1 rt2800usb
    rt2x00lib              53248  3 rt2800lib,rt2800usb,rt2x00usb
    mac80211              782336  3 rt2800lib,rt2x00lib,rt2x00usb
    
    cfg80211              602112  3 rt2x00lib,mac80211,rndis_wlan

    But when I connect a Linksys adapter, I can connect just fine:

    Code:
    Bus 001 Device 047: ID 13b1:000e Linksys WUSB54GS v1 802.11g Adapter [Broadcom 4320 USB]
    Basically, I have the same issue as mibakh above does.

    This seems to be a realtek issue as my Linksys Broadcom based wifi adapter works just fine. So, no this issue can not be called resolved.

    Edit: Ok, this is a 4.10.x kernel issue!

    By installing the 4.11-rc5 kernel, my Realtek wifi is now working again.

    Code:
    sudo wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11-rc5/linux-headers-4.11.0-041100rc5_4.11.0-041100rc5.201704022131_all.deb
    sudo wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11-rc5/linux-headers-4.11.0-041100rc5-generic_4.11.0-041100rc5.201704022131_amd64.deb
    sudo wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11-rc5/linux-image-4.11.0-041100rc5-generic_4.11.0-041100rc5.201704022131_amd64.deb
    sudo dpkg -i *.deb
    sudo reboot

    Re: Wifi not connecting in Ubuntu 17.04 Beta

    For me, installing the 4.11 rc kernel did and it didn't work.

    I used the live session to download the kernel deb files and copy them to the relevant 17,04 partition. After installing & rebooting the 17.04 install was still unable to connect to the Internet even with ethernet. So, I disabled the USB-WiFi in the BIOS. Still no Internet until I deleted the WiFi connection from Network manager.

    graham@sda6-zesty:~$ uname -a
    Linux sda6-zesty 4.11.0-041100rc5-generic #201704022131 SMP Mon Apr 3 01:33:30 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
    graham@sda6-zesty:~$ nmcli general status
    STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN
    connected full enabled enabled enabled enabled
    With WiFi disabled in the BIOS and Network Manager not showing any available WiFi access points, why is nmcli showing WiFi enabled?

    UPDATE:

    Curses. Foiled again!

    On subsequent reboot Internet access is broken. I have ungraded x 3 17.04 installs to the 4.11 rc kernel and Internet access is still broken with WiFi disabled in BIOS and WiFi connections deleted from Network Manager.

    Regards.

    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    Re: Wifi not connecting in Ubuntu 17.04 Beta

    The fix worked for me also running Ubuntu 17.04 fresh install on Lenovo P70 Mobile Workstation. Had to add:

    [device]
    wifi.scan-rand-mac-address=0

    to the /etc/NetworkManager/NetworkManager.conf file as described above. Thanks!
