Proxmox Node Connects to LAN but very intermittently, WAN

[Boothenender]

Hi

Thank you very much in advance for any assistance.

I have added a freshly installed Proxmox node (Lenovo M92P with updated BIOS) into a cluster with my existing machine (Existing machine: 192.168.1.200 - Gateway 192.168.1.1)

Both nodes can ping eachother and the rest of the LAN without any issue whatsoever. The first (oldest) node can also access the internet without any issue and retrieve updates and ping web addresses

The second node, whilst can see and connect to the LAN with ease, has very sketchy internet access, will not resolve DNS (so cannot update) and on a ping to a web address will get about 90-95% failure

It is worth noting that I have created a Debian VM on the node and I can ping the internet and have web access via the GNOME desktop
