Internet issue

General Help
#1

I'm new to this forum, so hello.

I'm having a strange issue with my internet connectivity. I'll try to explain. On my wired connection with this PC, my internet will stop recognizing my connection if I disconnect even once during the day. It will be fine throughout the day as long as I remain connected, but if I break the connection even a single time, it will act as if I have no connection at all even though it shows that I am connected in my settings.

I know it's not the ISP as I have another PC with a wifi connection (running Windows 10) that experiences none of these issues.

And after having left my (Zorin install) machine off all night, when reconnecting the next day, it will again maintain my connection as long as I don't disconnect. Restarting the machine doesn't fix my problem either, as there is some issue with the length of being disconnected that impacts this issue.

I really don't understand what could be happening at all. Very strange issue. Any help would be appreciated. Thanks.

Is anyone else noticing a trend, here?

Is that a problematic component? I have no idea.

It just seems to be the most likely device that shows up when users post having internet or bluetooth troubles, lately...

Here a possible fix. Open up terminal and write everything from below.

sudo rmmod r8169 r8168
sudo apt-get purge r8168-dkms
sudo modprobe r8169
dmesg | egrep -i 'eth|net|r816'
ifconfig -a

After that reboot the machine and check again :grinning:.

First, look through existing forum posts: Search results for 'Rtl8111' - Zorin Forum

Outside of those, I did already look up on the web and found several posts such as: https://www.linuxquestions.org/questions/linux-hardware-18/realtek-rtl8111-8168-8411-ethernet-controller-r8168-driver-install-r8169-driver-doesn't-work-4175641982/
that recommend removing the 8169 and installing the 8168. You can try that:
