Hi there,

After having huge issues with Windows I decided to dual boot my system and now run KDE Neon 20.04. Everything was going well accept for some persistent network issues I’m experiencing. My computer will constantly drop off the network or report limited connectivity. The only way to fix this that I have found is to disconnect from the network and then reconnect, but then the problem will occur again, and again. I do not believe this to be a router issue as other devices stay connected okay.

Is there anyway to fix this? Thanks

What kind of network? WiFi, LAN? On a PC or a Laptop? What kind of networking card is in the device, does it have proper firmware loaded?

Most network problems are hardware related, I suggest you check your networking hardware first.

I encountered this issue after a fresh kdeneon install. Before i used another distro without no wifi problem.

Hi all, same problem here. I'm using laptop dell latitude e7440. Wifi drops or better to specify: wifi stay connected, but with "limited connectivity" notification.
Sometimes it took 2 hours, sometimes sooner.. even during watching videos or browsing internet networking practically stops. When i've tried ping, its result in:
ping: www.google.com: Temporary failure in name resolution
And I need to reconnect to resolve the issue.
I'am using a lot of others distros on this PC (manjaro, win10, etc..) and I had never such problems. So I am sure it's not a HW issue. Must be a driver issue, or ?
Thanks for help. I like KDE Neon right out of the box

I solved this issue using manjaro kde.

KDE Neon plasma desktop was the only system on my LAN that experienced this issue.
Wired networking issue since I do not have KDE Neon installed on laptop.

Was your experience with the latest Ubuntu (21.04), or was it the same version that Neon is based on (20.04 LTS)?
It probably is a hardware issue, with the newer kernel in the latest Ubuntu supporting your network card better.

However even Ubuntu LTS has a newer kernel than Neon's base, at the moment. 5.8 versus the 5.4. Neon seem to be testing 5.8 in the Unstable version, so we might get that soon.
Or get it now: https://wiki.ubuntu.com/Kernel/LTSEnabl ... ack#Server

This post is made under the assumption that KDE plasma 5 desktop has an issue or bug with network connectivity.
This previous post was using Ubuntu 20.04 because KDE neon 20.04 was constantly displaying network connectivity warnings.
Today KDE neon has not displayed the network connectivity warnings yet, but this may have been caused by a router setting.
What are the triggers or flags that cause network connectivity warnings within KDE Plasma 5 desktop?
Hardware
NIC: Intel Ethernet I219-V
Software
Ubuntu 20.04 & KDE neon version 20.04 both on Kernel Version: 5.8.0-55
