wifi adapter D-LINK DWA-131 Not Working (SOLVED)
« on: October 17, 2018, 06:00:47 pm »
Anybody have an idea of how to make wifi adapter D-LINK DWA-131 work on a consistent basis? It works sometimes and sometimes it doesn't. I installed Peppermint 9 a few days ago and this is the only problem I seem to be having. It's loaded on a Dell Inspiron 1720 . . .

When you say it works sometimes, do you mean sometimes it doesn't work at boot .. but after a reboot it does

or do you mean wireless will suddenly drop out in the middle of using it ?

What's the output from:
Code: [Select]
lsusb
and
Code: [Select]
lspci -vnn | grep -i net
and
Code: [Select]
rfkill list
and
Code: [Select]
lshw -C network
and
Code: [Select]
inxi -Fz

Next time it doesn't work on boot, run:
Code: [Select]
lsmod | grep r8712u
and let me know if anything was returned

If nothing was returned, try running
Code: [Select]
sudo modprobe r8712u
and let me know if wireless sprang to life

if it IS listed in the return from the first command, instead run:
Code: [Select]
sudo rmmod r8712u
then
Code: [Select]
sudo modprobe r8712u
and let me know if wireless sprang to life.
