I've identified the kernel from where this issue occurred at first time its kernel 4.3 and after looking the above link i still cant get the exact meaning of bisection or how to bisect a kernel...
Kernel without issue http://kernel.ubuntu.com/~kernel- ppa/mainline/linux-3.19.y.z-review/ On last kernel(which i installed by myself) wifi worked is kernel 4.2 and distribution is ubuntu 15.04 I think something is wrong with network manager and rfkill as well in Ubuntu 16.04 i.e. the network manager doesn't load the interference name by itself I'll have to manually enter the command sudo ifconfig interface-name up sudo service network-manager restart And if somehow after compiling the driver and executing the above wifi shows up then it doesn't detects any hotspots or available connections in ubuntu 16.04. Also the rfkill shows the "hardware block: yes" it fails to unblock the device even by pressing the wifi key or by executing the command "rfkill unblock all". I had also reseted the BIOS but nothing worked. Ralink r3290 having too much issues with ubuntu as compared to windows. We want any working driver for it. ** Changed in: linux (Ubuntu) Status: Triaged => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577140 Title: Wifi Ralink R3290 disabled by default in ubuntu 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577140/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
