Fresh install - no internet access

English Network/Internet
#1

I freshly installed Leap 42.3, but do not have internet access. I can’t ping my router, my desktop is connected via ethernet. I have looked through multiple posts and none of them helped solve my problem, but they did help me gather information. If you would like to see more information please ask.

Here are my terminal commands and their respective responses:

samuel@linux:~> ping 130.57.66.6
connect: Network is unreachable

Thank you for any help and advice you give me.

#2

How do you set up your Network?

Yast2/wicked or Networkmanager?

If Wicked:
Do you setup it in Yast2----System ----Network?
Do you set a Route/Gateway?

#3

I tried both wicked and NetworkManager, neither worked. Currently I have it setup with wicked. I tried setting a route/gateway but that did not work so I removed it. I did set wicked up through Yast. I don’t have a preference on which one to use.

Thank you for your reply.

#4

Do you have DHCP server on your network?

#5

Yes, my router dynamically assigns ip addresses.

#6

What does


cat /etc/resolv.conf

give

Try this


rm /etc/resolv.conf
rcnetwork restart
#7

C’mon, interface does not have IP address, how exactly gateway or /etc/resolv.conf help in this case? From the posted log snippets wicked appears to have attempted to acquire DHCP address on interface. I would start with setting static address to verify that NIC works at all.

#8

Removing it did nothing, even after rcnetwork restart and a reboot.


samuel@linux:~> cat /etc/resolv.conf 
### /etc/resolv.conf file autogenerated by netconfig!
#
# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:
#     NETCONFIG_DNS_STATIC_SEARCHLIST
#     NETCONFIG_DNS_STATIC_SERVERS
#     NETCONFIG_DNS_FORWARDER
# or disable DNS configuration updates via netconfig by setting:
#     NETCONFIG_DNS_POLICY=''
#
# See also the netconfig(8) manual page and other documentation.
#
# Note: Manual change of this file disables netconfig too, but
# may get lost when this file contains comments or empty lines
# only, the netconfig settings are same with settings in this
# file and in case of a "netconfig update -f" call.
#
### Please remove (at least) this line when you modify the file!
#9

Can I just set it statically from wicked, or do I need to set it from the router?

#10

Configure a static IP address (suitable for your LAN network) via YaT > System > Network Settings > Overview, select the NIC and ‘Edit’. Follow the prompts given.

More info here…
https://doc.opensuse.org/documentation/leap/reference/html/book.opensuse.reference/cha.basicnet.html#sec.basicnet.yast.netcard.change

#11

Thank you everyone for your help so far. I statically assigned my desktop an address following the instructions by deano_ferarri and tried to ping my router and it actually tried to ping, but each ping said “Destination Host Unreachable”.

#12

I know posting output can be tedious without a network connection on the machine concerned, but for this to work at all the IP address and subnet mask should be set to be compatible with the router IP addressing. Do you happen to know for sure your router’s LAN IP address? Can you tell us what you assigned on this machine?

#13

My routers IP is 192.168.1.1, I set my IP to 192.168.1.115 because my router will take up to 254 or so. My subnet mask is 255.255.255.0.

No, it does not appear so. I only checked a couple.

#17

I note that you’re getting errors reported when pinging. I’m not sure if this is driver or hardware related, but that’s what needs further investigation.

#18

I am going to take a guess and say that it is an issue with the driver since the hardware was working fine when I was running it in windows. I just removed the dual boot by doing a complete fresh install. I was dual booting with opensuse 42.3 before but don’t remember having any issues before. I’m guessing that I will have to try to find the driver from the manufacturer and load it?

#19

Hardware and driver details?
