KDE Plasma 5 Netwrok Issue - PacketLost/Timeout after resume Suspend

Hi all,
I have a serious issue on Network connection and mostly happen after resuming from suspend on WIFI as well as Ethernet. I sometimes face to this issue before but it almost always happen after last update on 24-04-2018 even when I reboot the system and change the access point no matter I was resume from the suspend or after system reboot (I do always keep my system update to date and almost every day I do run yaourt -Syyua.)

Currently I am using KDE plasma 5.

Plasma Shell version: 5.12.4
System updated on 26-04-2017

Re: KDE Plasma 5 Netwrok Issue - PacketLost/Timeout after resume Suspend

I still have the problem with this.
as you can see in below I had multiple rroute entry.

 sudo route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.43.1    0.0.0.0         UG    303    0        0 wlp8s0

192.168.43.0    0.0.0.0         255.255.255.0   U     303    0        0 wlp8s0
192.168.43.0    0.0.0.0         255.255.255.0   U     600    0        0 wlp8s0

after connecting and disconnecting a few times the route table get fixed.

I tried to get connected by th wifi but I did not have any internet access, here is the journalctl output

journalctl -f -u NetworkManager.service

Re: KDE Plasma 5 Netwrok Issue - PacketLost/Timeout after resume Suspend

FWIW NetworkManager's internal dhcp tends to have issues like that, see if switching to dhclient resolves this: https://wiki.archlinux.org/index.php/Ne … HCP_client

Re: KDE Plasma 5 Netwrok Issue - PacketLost/Timeout after resume Suspend

Thanks for the reply,
I am not sure is it correct or not, but in the system I didnt have /etc/dhclient.conf and /etc/NetworkManager/conf.d/dhcp-client.conf files, so i just created it and added the below:

cat /etc/NetworkManager/conf.d/dhcp-client.conf
[main]
dhcp=dhclient
interface "enp7s0" {
   send dhcp-client-identifier MACADDRESS;
}
interface "wlp8s0" {
   send dhcp-client-identifier MACADDRESS;
}

would be appreciated if you let me know whether is correct or I need to add more parameters.

Re: KDE Plasma 5 Netwrok Issue - PacketLost/Timeout after resume Suspend

Should be ok, I've never had issues with  dhclient identifiers so the /etc/dhclient.conf might be redundant, but is likely to not hurt if present either way.
