    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:

    1. Is the NIC up with an IP address?
      Code:
      ip addr
    2. Can you connect to another system on your LAN?
      Code:
      ping -c1 <IP-address of your router>
      (I hope you know that address)
    3. Do you have a default route to the Internet?
      Code:
      ip route
    4. Can you connect to a system on the internet?
      Code:
      ping -c1 130.57.66.6
    5. Can you resolve host/domain names?
      Code:
      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
    Code:
     ip addr
    Code:
    z8603@linux-wd2g:~> 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:

    1) Check system updates
    2) Install software
    3) Install multimedia codecs
    4) Install proprietary graphics driver.

    Hope that help!

    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:


    Code:
    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 
           valid_lft 924172sec preferred_lft 319372sec
        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.
    openSUSE Leap 15.1; KDE Plasma 5;
