I think this might be due to a new network-manager bug, as I've also started experiencing this problem only recently - I think after upgrading to Ubuntu 15.04. It seems I've managed to solve this problem temporarily as a workaround (although it doesn't seem to work every time) with these two files: I have a script file to watch the WiFi connection and ...

EDITED BASED ON UPDATED INFORMATION Your wifi card seems have trouble with 12.04 kernel and you may need to compile kernel yourself.

network-manager is interferring with the change of mac address. You can automate the mac spoofing with an udev rules. It will be applied automatically while booting. Create a file /etc/udev/rules.d/99-mac-spooing.rules with the following content ACTION=="add", SUBSYSTEM=="net", ATTR{address}=="XX:XX:XX:XX:XX:XX", RUN+="/sbin/ip link set dev %k address ...

This command should restart basic networking. sudo service network-manager restart As a side note, this won't restart any other daemons. Some fixes might require a full restart, and this command won't necessarily replace that, but it will restart networking.

I prefer to run these two commands sudo service networking restart sudo service network-manager restart Or an other option sudo /etc/init.d/networking restart sudo /etc/init.d/network-manager restart A log out or something isn't necessary. Or in Ubuntu 15.04 you should use Systemd: sudo systemctl restart networking sudo systemctl restart ...

There are a couple of steps I suggest. First, I notice this in the pastebin: Hardware name: /D54250WYK, BIOS WYLPT10H.86A.0021.2013.1017.1606 10/17/2013 There is an updated BIOS available here: https://downloadcenter.intel.com/download/24881/BIOS-Update-WYLPT10H-86A- I suggest you update it.

This problem is now solved! After numerous reinstalls, I finally got the "sudo apt-get install bcmwl-kernel-source" to finally go through! What I did differently this time is when it asked me to install, I check marked both the boxes, Download and Install when it asked me about the proprietary devices.

Your wireless wl driver is not installed. You probably tried to install a wrong version that did not build for 14.04. When wl driver is installed, lspci -knn | grep Net -A2 shows Kernel driver in use: wl Install the driver this way.

modprobe -r is used to remove a kernel module. You can blacklist the module so that you donot have to remove it after every boot. For this open a terminal and type: sudo nano /etc/modprobe.d/blacklist.conf By the above command we are asking nano, the Ubuntu GUI text editor to open /etc/modprobe.d/blacklist.conf. But normal users do not have permission ...

Pilot6 has a PPA that will fix the problem without blacklisting ideapad-laptop First we need to add the PPA sudo add-apt-repository ppa:hanipouspilot/ideapad-laptop Then we can install it with sudo apt-get update && sudo apt-get install ideapad-laptop-dkms Then reboot The only possible problem is if you have a broadcom wifi card that uses ...

I have compiled the ratek driver http://cdn-cw.mediatek.com/Downloads/linux/2010_0709_RT2870_Linux_STA_v2.4.0.1.tar.bz2 . It throws two errors but they could be corrected by replacing: "current_fsuid()" by "current_fsuid().val" "current_fsgid()" by "current_fsgid().val" Then: make clean make make install At this point, I have compiled the driver. ...

I will probably be criticized, but I am adding this information, because it gives a clue how to install a driver for this device in Ubuntu. Probably someone will write a complete step-by-step guide. I analyzed a Windows driver and found out that this dongle is based on Mediatek rt2870 chip. It is not supported by linux kernel yet. It is declared that ...
