Public bug reported:
Guys,
I just installed Ubuntu 15.04 on a brand new Dell E7440 Laptop and
Network Manager disable the Router Advertisement for my IPv6 connection!
My connection settings for both wired and WiFi have:
Edit Connection -> Edit Settings -> IPv6 Settings -> Method = Automatic
But, take a look:
---
root@ultra:~# cat /proc/sys/net/ipv6/conf/wlan0/accept_ra
0
root@ultra:~# cat /proc/sys/net/ipv6/conf/eth0/accept_ra
0
---
So, my IPv6 connection doesn't work. I need to manually re-enable it,
by running:
---
echo 1 > /proc/sys/net/ipv6/conf/wlan0/accept_ra
---
Then, my IPv6 works again! Everything I reconnect to a network, I need
to "echo 1 > accept_ra" again... Very annoying.
Please, help!
Thanks in advance...
Cheers!
Thiago
