networking - Permanently enable Wifi in 16.04 - Ask Ubuntu

i have ralink rt3290, not have built-in driver in 16.04, installed 1 following this answer.

at every login, wifi not enabled. can enable running:

sudo ifconfig rename3 sudo service network-manager restart 

after works fine (rename3 logical name of device, no idea why).

how can enable wifi default, not need type @ every login? (an ad-hoc script @ start not looking for)

edit: in this link there relevant information, suggested chili555 in comment.

i don't know driver rt3290sta except, working on years, know it's getting bit old. fact interface appears 'rename3' suggests it's unhappy driver. rather tweak settings , default driver rt2800pci working well.

please open terminal , do:

gksudo gedit /etc/modprobe.d/blacklist-ralink.conf 

use nano or kate or leafpad if don't have text editor gedit. change file read:

#blacklist rt2800pci #blacklist rt2x00pci blacklist rt3290sta 

proofread carefully, save , close text editor. set regulatory domain explicitly. check yours:

sudo iw reg 

if 00, one-size-maybe-fits-all setting. find yours here: http://en.wikipedia.org/wiki/iso_3166-1_alpha-2 set temporarily:

sudo iw reg set 

of course, substitute country code if not iceland. set permanently:

gksudo gedit /etc/default/crda 

change last line read:

regdomain=is 

proofread carefully, save , close text editor.

finally, default driver, rt2800pci, seems troubled 802.11n. if router capable of it, suggest switch mixed 802.11b, g , n b , g only.

i notice this:

channel occupancy:   5   aps on   frequency:2.412 ghz (channel 1)   2   aps on   frequency:2.437 ghz (channel 6)   8   aps on   frequency:2.462 ghz (channel 11) 

your router on crowded channel 1. suggest change channel 6.

reboot computer , router , let hear report. edit answer needed add further troubleshooting steps.
