Random Disconnect from internet for some websites.

English Network/Internet

Hi there!

I have a rare issue, that Leap 15.3 randomly disables internet connection for some - not all - websites. Chromium web browser. It happens 2 or 3 times a day. In that situation, I need to reboot the machine and then all is good, until a new disconnect.

Any ideas, why is this happening?

Thanks in advance,
Vadim.

Hi
Wireless or wired? Could be your dns servers… have you just tried restarting the network rather than reboot?

Hi.

Itś wireless.
How can I restart a network with command line - sudo networkctl restart?
Also, do I need to reset (how do I) dns table?

Thanks,
Vadim.

Hello, this reminds me problem I had with my Tumbleweed desktop (a year back or so). I have been using NetworkManager, so I replaced it with wicked and the problem disappeared. You can do this in yast2. NetworkManager works fine on my leap though.

I forgot, when I want to restart network I do this (just replace enp31s0 with your network IF name, which you can find with “ip a” command):

sudo ip link set enp31s0 down; sleep 5; sudo ip link set enp31s0 up

Hi
The command rcnetwork restart will suffice. Check your DNS settings via;


cat /etc/resolv.conf

I don’t use my ISP ones as they are always flaky, use openDNS or google ones. Normally they are configured in your router.

Hi.

Yes, the sudo rcnetwork restart helped - there is no need to reboot again. Thanks.

There is nothing in settings of router that is DNS related…
How can I change DNS settings in Leap? I need to disable Network Manager first in Yast?

Thanks again,
Vadim.

Hi
You should be able to go into the Network Manager settings and for your connection profile manually set them up (You can on the GNOME DE)?

So, I have changed the Network Manager settings for DNS in favor of Google ones. Now, the applet shows the Google nameservers for this Wi-Fi connection.
I’ll see, if it helps.

Thanks, Vadim.

Hi.
That not helped, I have random disconnects.
I feel, that I need to do a fresh install…
Thanks,
Vadim.

Hi
I would open a terminal and switch to root user and tail the journal (journalctl -f) and when it disconnects see what log information is recorded. Could be the wireless device and power settings.

I meant, that disconnects are for some, not all of the websites…
Thanks,
Vadim.
