16.04 beta: dns not set automaticly

[Klavs Klavsen]

I just installed ubuntu 16.04 on a laptop, and after this, I had to install b43 firmware to get wifi working (as expected).
When this was done - I could not see any available wireless networks in NetworkManager applet, so I had to install wicd-gtk - to be able to choose a wireless network and connect to it.

Now it connects fine - but nothing is shown in nm-applet my taskbar, and DNS isn't set correct (it seems it isn't set at all), when it gets a DHCP address. (dhcp and wifi works fine on my ubuntu 14.04 machines).

I tried running nmcli dev show - and it does not show any DNS information at all.

when I switch resolv.conf to use 8.8.8.8 as nameserver - dns works fine.

It feels as if I'm missing something for network-manager, to make it properly handle wireless, and that wicd-gtk doesn't do the job exactly right ?

but "ip a" shows the address for wlp2s0b1 correctly.
