The same ADSL router (Huawei HG633) works fine for my Ubuntu desktop when connected over wifi, but when I try doing "sudo apt update" on a newly-installed Ubuntu Server 16.04.1 it doesn't detect the internet. I am connected to the router using an Ethernet cable.
Is this a known issue with Ubuntu Server and ADSL routers?
Edit: (sorry to post a screenshot but I couldn't get anything off of this machine another way)
