Hi All

I just installed KDE 18 64 two days ago. I've been a linux user for years, without any issues with hardware compatibility.

The only issue I'm having now is that neither my onboard or PCIe card will establish a connection after resuming from suspend mode. The error is "cannot establish connection". A reboot always reestablishes a connection, but I work exclusively online and suspend is an essential function for me.

I've tried a fresh install twice using software from different download mirrors and chosen install media, too (tried installing from both USB and DVD).

I've posted the inxi outputs for both cards below, for when the card is working after a full boot and after suspend when it won't connect. Nothing seems to change.

Hoping someone can offer some better insights. I'm hesitant to use the old workarounds suggested online (such as this one https://ubuntuforums.org/showthread.php?t=2004690), as most aren't KDE specific and I don't want to bugger up anything further.

External card (PCI Express)

Before suspend:

Card: VIA VT86C100A [Rhine] driver: via-rhine port: d000 bus-ID: 02:06.0
IF: enp2s6 state: unknown speed: 100 Mbps duplex: full mac: <filter>

After suspend:

Card: VIA VT86C100A [Rhine] driver: via-rhine port: d000 bus-ID: 02:06.0
IF: enp2s6 state: unknown speed: 100 Mbps duplex: full mac: <filter>

Onboard card

Before suspend:

Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
driver: r8169 v: 2.3LK-NAPI port: d000 bus-ID: 02:00.0
IF: enp2s0 state: up speed: 1000 Mbps duplex: full mac: <filter>
Card-2: VIA VT86C100A [Rhine] driver: via-rhine port: c000 bus-ID: 03:06.0
IF: enp3s6 state: down mac: <filter>

After suspend:

Card-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
driver: r8169 v: 2.3LK-NAPI port: d000 bus-ID: 02:00.0

Card-2: VIA VT86C100A [Rhine] driver: via-rhine port: c000 bus-ID: 03:06.0
