Packet loss to/from Proxmox host/CT

[Sandbo]

I have recently assembled a new workstation using Asus Zenith 2 Extreme which has multiple NICs.
The intel one is what I am using for connecting to the host (for now):
Intel® I211-AT, 1 x Gigabit LAN Controller(s)

After a fresh installation of Proxmox, I realized that the Web GUI is often slow and sometimes say connection loss.
Then, on checking the ping (between a LAN computer), there are packet loss happening intermittently, and it occurs more frequently when I am actively browsing through the web interface. On average, it is about 10-15% packet loss when it works better.


I have PVE installed on another system in the same LAN network and it runs perfectly, though the location is not exactly the same in the office.
I should check the local network (like if the switch is broken) more before attributing it to Proxmox, but would you have any advice on debugging it in the mean time?
Many thanks.

Hm - one of the issues that might be causing this would be a duplicate IP-address or MAC address on the network - check that no other device has the same IP (and MAC) as your proxmox node.

I hope this helps!

Thanks for the reply, I thought about that, but even the guest OS which obtains IP from DHCP also suffered from some degree of packet loss. (say, if I ping from a guest to the router at 192.168.100.1)
Before concluding this issue being a Proxmox one, I will try to boot it from a USB to ubuntu to see if it happens there also.
