networking - RT3090 Wireless is 'disabled' - fixed, and problem came back - Ask Ubuntu

i've installed ubuntu server 16.4 on minipc, rt3090 wireless card. @ first, wifi wasn't working.

lshw -c network         ....      *-network disabled           description: wireless interface           product: rt3090 wireless 802.11n 1t/1r pcie           vendor: ralink  

found recommendation blacklist these modules:

#z copied http://askubuntu.com/questions/478018/ralink-rt3090-in-ubuntu-14-04-very-bad-reception-keeps-disconnecting blacklist rt2800usb blacklist rt2x00lib blacklist rt2x00pci blacklist rt2x00usb blacklist rt2800mmio blacklist rt2x00m 

as far remember, @ point - annoying disabled gone. managed connect manually wifi wpa_supplicant. installed few packages such networkmanager, tried make connection automatic - , i've lost wifi :-( i've removed networkmanager, assuming made conflict.

now, in lshw network disabled again.

tried rfkill - i'm not sure, seems ok me:

$ rfkill list 0: phy0: wireless lan         soft blocked: no         hard blocked: no 

• what have disabled wifi, after worked?

in dmesg, see this:

 [    8.519249] rt2800pci 0000:02:00.0 wlp2s0: renamed wlan0 

• does mean rt2800pci not blacklisted?

searched /var/log/kern.log , found interesting thing:

it seems it's time wifi worked me - , loaded rt2860.bin - isn't mentioned further.

• how return rt2860.bin?

the interface showing disabled interface not declared in /etc/network/interfaces. please amend file to:

source /etc/network/interfaces.d/*  auto lo iface lo inet loopback  #auto enp1s0 iface enp1s0 inet dhcp  auto wlp2s0 iface wlp2s0 inet static address 192.168.1.25 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.1.1 8.8.8.8 wpa-ssid <your_network> wpa-psk <your_secret_key> 

i suggest static address in server can ftp , ssh it. sure select static address outside range used dhcp server in router, switch or other access point.

also, blacklist makes no sense whatever. suggest do:

sudo gedit /etc/modprobe.d/blacklist.conf 

use nano or kate or leafpad if don't have text editor gedit. remove these lines added.

proofread carefully, save , close text editor.

detach ethernet cable, reboot , tell if connected.
