Eu encontrei a solução para configurar a conexão sem fio de 2,4 hz. Depois de atualizar o /etc/network/interfaces
. Eu devo ter reiniciado o sistema ....
De qualquer forma, aqui está o código
# interfaces(5) file used by ifup(8) and ifdown(8)
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface (eth0)
auto eth0
iface eth0 inet dhcp
# IPv6 Address Blocks
# Add a static block for your default public IPv6 address, and include a directive for its gateway.
iface eth0 inet6 static
address 2001:db8:a0b:12f0::1/64
gateway fe80::1
# add an additional block for each IPv6 address you need to configure.
iface eth0 inet6 static
address 2001:db8:2000:aff0::1/64
