Wifi works in windows, so its not a hardware problem.

After installing Ubuntu 16.10 on my Lenovo Thinkpad 510, the wireless is not working. In the network manager it says 'device not ready'

$ iwconfig
lo        no wireless extensions.

enp0s25   no wireless extensions.

wlp3s0    IEEE 802.11  ESSID:off/any

          Retry short limit:7   RTS thr:off   Fragment thr:off

$ sudo iwlist wlan0 scan
wlan0     Interface doesn't support scanning.


$ lspci -nn | grep -e 0200 -e 0280

I have tried:

Output from dmesg | grep iwl is on http://pastebin.com/S2c9C3E4

Running sudo modprobe -r iwlwifi && sleep 20 && sudo modprobe iwlwifi produces no output.

$ echo "options rtl8723be fwlps=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

outputs options rtl8723be fwlps=N

Have also tried sudo service network-manager restart but this also did not help.

$ cat /etc/modprobe.d/iwlwifi.conf
# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211

Also tried https://askubuntu.com/a/770714/17643 but this also did not work.

Also tried sudo apt-get install --reinstall linux-firmware but this also did not help.

Also, based on https://ubuntuforums.org/showthread.php?t=2188827&p=12855191#post12855191, /etc/rc.local - Im not sure if this is supposed to be empty.

  • See if installing Ubuntu 16.04 or 16.04.1 fixes this issue, otherwise file a bug report, you can get some info here File the bug against package linux – Jeremy31 Feb 25 '17 at 20:34
