It's possible for devices to change names in Proxmox when new hardware is installed. Check the NIC names with `ip a` before you do anything else.I just received my TL-D400S and I installed the included QXP-400eS-card in an MS-01 running proxmox. I lost my network-connectivity.
HELP
I'm using a 10G fibre-module in an SFP+ port. When I install the card, I don't have network-connectivity anymore. Removing it gets my network back. Any help ? At the moment, the DAS does not have any disks.
lspci sees the card.
The lights on my switch connected to the fiber-cable light and I have an ip-address (although with a fixed address that does not say much). Pinging does not work, not to local network, not to global network.
