Connection issues after upgrade to Leap 15.3

English Network/Internet

I upgraded to Leap 15.3 from Leap 15.2 yesterday on my desktop computer with ethernet card in motherboard and since then I see disconnections every hour (or 50 minutes). What can be problem?

… and every about 50 minutes similar log, where is new “address, plen, gateway, lease time” appears and network stops for about 10s

Hi
Since your on an ethernet interface, if you use YaST Network Settings and switched to wicked, does the issue duplicate? Ethernet Cable all ok? Desktop power settings?

Hi Leinad965,

I can only guess. Maybe this has something to do with your issue?

Checking my log the setting is 864000. What I do not know: is that a setting made in NetworkManager or made by your router resp. DHCP server. I can’t find anything in /etc/NetworkManager/.

Is /etc/dhclient.conf used by networkmanager?

There is a line (commented out):

# uncomment to request a specific lease time, otherwise
# the dhcp server will provide its default lease time:
#send dhcp-lease-time 3600;

Is there an uncommented line giving 7200? Or in any other config file?
I have to say I’m still on 15.2, so my findings may not be representative.

Thank you for the tips, I will try the lease time first and if not, then if wicked helps. I found some settings on router to 120 minutes, so I am trying to increase to max.
