Vipan - If you are live booting Ubuntu 18.04 please boot the live USB after you have turned off your machine completely. If you boot Live ubuntu 18.04 after restarting your machine from the previous Ubuntu version (where WIFI doesn't work) release then the WIFI will not work in Live mode. It's kind of weird but that's how it works in my case.
In short, To test your WIFI do not boot into Previous ubuntu release (which is installed on your computer). If somehow you have logged in Previous Ubuntu then shut down the Ubuntu and then boot into LIVE USB directly. It would show up your WIFI device. If it doesn't show up then there could be something messing up with your kernel module. -- 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
