I'm trying to connect my computer with a old wifi usb key (with ubuntu 16.04).
I've the connection, the wifi icon is ok, but when I'm using a web browser : no connection.

I've post on a french ubuntu forumm, here. So the commands I've launch are, with wificheck, here.
And, I've remove WPA/WPA2 method to keep only one "WPA2", here, with the web administration panel on my internet box.

I'm on DHCP, and I think this service is ok :

~$ sudo nmap --script broadcast-dhcp-discover -e enp5s0



Starting Nmap 7.01 ( https://nmap.org ) at 2019-01-06 17:30 CET

Pre-scan script results:
