I ran my debian install wirelessly. I "just" selected wifi card, then ssid, encryption, password. Then selected dhcp, not fixed addresses.
Network connected, finished install over network.
After boot into new system, I expected network to be working over wifi, just as it is when I install over Ethernet: The settings used on install is the settings used in running system.
Apparently it's not so with wifi; I have to fiddle with
Or is there a simple way to start wifi with the installer-used settings?
During install, /target/etc/network/interfaces contain
# The primary network interface allow-hotplug wlp4s0 iface wlp4s0 inet dhcp # This is an autoconfigured IPv6 interface iface wlp4s0 inet6 auto wpa-ssid MYSID wpa-psk MYPASSWD
but after install it doesn't contain references to the wifi interface. I saved the file during installation, and used it after install. It works, but ...
- I get a link IPv6 after 30 sec
- I get a global IPv6 after 1 minute
- I get a DHCP IPv4 after 7 minutes.
If I remove the inet6 auto line from /etc/network/interfaces
allow-hotplug wlp4s0 iface wlp4s0 inet dhcp wpa-ssid MYSSID wpa-psk MYPASS
I get and IPv4 AND IPv6 so fast it is already ready if I log in as fast as possible after boot.
