Lost internet connection after upgrade from 42.3 to 15.0

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.

The way I updated to Leap 15:

  1. I changed paths in respositories from 42.3 to 15.0

  2. Then I run:


          zypper dup 

  1. and i rebooted a computer after the process

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:

                                                     In Network settings, at the "Global" tab I chose  "wicked".

At the Overview tab, I selected the network device and change to DHCP, and after that I filled in the informations about my network.

Rest of recommended commands I used:

          ping -c1 192.168.0.1

I will appreciate any help!

Its an DNS Problem.

As root:

netconfig update -f
