[Resolved]Cannot connect to internet in Helium release

I am in the process of installing Helium on a 32-bit Dell tower. When I run 'uname -a' on the host, I get:

Linux herman 4.9.0-9-686-pae #1 SMP Debian 4.9.168-1+deb9u3 (2019-06-16) i686 GNU/Linux

I have a network connection, but it seems to me that the DNS is not working.

I can ping any of the hosts or the router in my intranet and I can run 'ssh' and login in on other hosts. In addition, I can ping IP addresses on the internet and I get a positive response, but I have to use the IP address, not the domain name. For example, I can:

ping 78.47.156.207

but

ping www.bunsenlabs.org

does not work  and I get the error message:

ping www.bunsenlabs.org: Temporary failure in name resolution

I have installed Helium on one other machine and the only difference in /etc/network/interfaces on the two hosts, is the host IP address. The interfaces file on the problem machine, 'herman', is:

 1 # This file describes the network interfaces available on your system
  2 # and how to activate them. For more information, see interfaces(5).
  3 
  4 source /etc/network/interfaces.d/*
  5 
  6 # The loopback network interface
  7 auto lo
  8 iface lo inet loopback
  9 
 10 auto eno1
 11 iface eno1 inet static
 12 address 192.168.0.249
 13 netmask 255.255.255.0
 14 
 15 gateway 192.168.0.1
 16 broadcast 192.168.0.255
 17 
 18 dns-nameservers 8.8.8.8

The output of 'ip addr show' is:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 90:b1:1c:98:dd:22 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.249/24 brd 192.168.0.255 scope global eno1
       valid_lft forever preferred_lft forever
    inet6 fe80::92b1:1cff:fe98:dd22/64 scope link
       valid_lft forever preferred_lft forever

So, I'm pretty sure there is a DNS problem, but I can not find a way to resolve the problem.

I would appreciate suggestions and help. Thank you in advance.

Re: [Resolved]Cannot connect to internet in Helium release

Maybe it expects to find DNS on the ROuter, but the Router does not provide that?
Can you edit the connection in Network-Manager and manually add DNS servers (under IPv4 & IPv6 settings)?
I remember I sometimes chose "Automatic, Addresses only", then added DNS servers below.
