Wifi wasnt working in debian 9.0.1

#1 Post by mharris »

I bought this cheap $5 usb wifi dongle https://www.amazon.com/gp/product/B01DS ... UTF8&psc=1

It didn't work with Debian 8.8 and sources wouldn't compile etc so i went ahead and installed debian 9.0.1 from the non-free gnome live cd which included the necessary drivers to get the card to be recognized.

Wireless networks were detected but it couldnt connect to any of them.

I remembered this fix i had to do for ubuntu testing on the same machine with a different card that i did not have do do for debian 8.8. SO.... i tried it and it works.

The odd thing is that it was not required for debian 8.8, but the wifi adapter does so there is an improvement.

long story short,

Code: Select all

sudo nano /etc/NetworkManager/NetworkManager.conf
and add

Code: Select all

[device]
wifi.scan-rand-mac-address=no 
and run

Code: Select all

sudo service network-manager restart
and it might start working for you as well. Hope this saves someone some time.

Thank you very much, I haven't realized that it's actually this issue. There are a couple of posts reporting this issue recently, and I told them to disable systemd's predictable ifnames... :oops: Although (coincidentally?...) that will also work, now I guess it's a overkill. Your solution should be the standard.
