Wireless or wired? Desktop used???

Didn’t it try to setup the network during the installation? And what were the results there?

There is a general recipe to walk down with network problems:

You check from bottom to top:

```
Is the NIC up with an IP address?
```

ip addr

Can you connect to another system on your LAN?

ping -c1 <IP-address of your router>

(I hope you know that address)

Do you have a default route to the Internet?

ip route

Can you connect to a system on the internet?

ping -c1 130.57.66.6

```
Can you resolve host/domain names?
```

ping -c1 forums.opensuse.org

Take care. As soon a one step fails, that must be resolved first. It is useless to go to the next step before it is resolved.

So start with 1. and do not hesitate to post the output here to get help on the interpretation.

I’ve got a wireless Desktop.

It did try to set up the network during installation but i must have done something wrong. Alas, i didn’t save the results.

The output of

 ip addr

You indeed have no IP set at all.

As you use a desktop, I assume that using wicked maybe fine.

Use YaST > Network Devices > Network settings.

At the Global tab choose for wicked (when not already set).

At the Overview tab, select the network device and click Edit below.

Assuming you want to use DHCP to set network parameters from the DHCP server in your router, choose Dynamic address. Click Next.

On the next screen you call fill in the SSID of your network and security parameters. Next.

I think that is it.

When question, please come back here. When success, please report also.

You even didn’t highlight your problem. However, few things you can try:

Check system updates
Install software
Install multimedia codecs
Install proprietary graphics driver.

Hope that help!

hcvv · September 7, 2018, 4:53pm

I assume that all four point above are a bit difficult to do when the OP has no network connection.

Hi! I have the same problem. I did not use my openSuse a while, so today I tried to update from 42.3 to 15.0. Update have gone quite ok (I guess - all other programs work well), but I cannot established wireless connection. When I try “ip addr” command, I get something that looks like:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    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: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether 60:02:92:25:97:65 brd ff:ff:ff:ff:ff:ff
3: wlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether a0:a8:cd:0d:06:ec brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.199/24 brd 192.168.0.255 scope global noprefixroute dynamic wlan1
       valid_lft 3362sec preferred_lft 3362sec
    inet6 2a02:a310:8239:4100:b87d:8dc8:550:fd3d/64 scope global temporary dynamic 
       valid_lft 604565sec preferred_lft 85806sec
    inet6 2a02:a310:8239:4100:a2a8:cdff:fe0d:6ec/64 scope global mngtmpaddr noprefixroute dynamic

    inet6 fe80::a2a8:cdff:fe0d:6ec/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

and still I do not have a connection. I already try to solve it this way:

Network settings.
At the Global tab choose for wicked (when not already set).
At the Overview tab, select the network device and click Edit below.
Assuming you want to use DHCP to set network parameters from the DHCP server in your router, choose Dynamic address. Click Next.
On the next screen you call fill in the SSID of your network and security parameters. Next.

I will appreciate any help!

It would be better to start your own thread. That makes it less confusing.

Please indicate what method you used to update to 15.0.

The way I updated to Leap 15:

I changed paths in respositories from 42.3 to 15.0
Then I run:

zypper dup

and i rebooted a computer after the process

nrickert · April 24, 2019, 10:50pm

Since pings by IP worked, it seems that your only problem is with DNS.

My usual advice for this:

Remove the file “/etc/resolv.conf” and then reboot.

However, an alternative is to run (as root)

netconfig update -f

Aransiola_IR · August 31, 2019, 4:04am

Hello, please I have tried all the above options and still can’t connect to the internet
The ping test worked except ‘‘ping forums.opensuse.org’’ is it possible that a netconfig settings solve if so please advice me on what to do

I have the same problem, neither “install” nor “update” (from net.iso 15.1 or 15.2 Alpha) works within an IPV4 network with ipv4 DHCP Server. May be there is a bug in setting the priority of DCP IPV4 and IPV6 call. I cannot setup new 15.1 or 15.2 VMs in a longtime working IPV4 XEN environment.

As standard within the last 6 or 7 major releases, the opensuse versions xx.3 will work. From opensuse 10.x on, all xx.0 versions did not work seemless as servers.
