I have an HP r007 tu laptop with preinstalled Win8.1. I installed Debian-Jessie derivative along with Win8.1. Its Ralink RT3290 wireless card is neither showing up in device manager in Windows nor in debian. I tried ifconfig wlan0 up but it does nothing, gives this message:
wlan0: ERROR while getting interface flags: No such device
I then tried
rfkill unblock wlan
even that didn't worked. How can I get it to function properly?
Even when it detected WiFi networks, it was a poor performer, needed to reset it often at that time. Can hardware failure be a possibilty?
