I know that I did something wrong and I am pulling my hair out trying to figure out what I did...

Preface:

Please know that before creating this post I did my absolute best to not bother you fine folks with this request, scoured the forums, tried some fixes….then tried all the fixes and I am still at the same spot as I started

It should also be noted that I BARELY know what I am doing in comparison to a lot of you, so take that for what it is.

Problem:

I have very slow download with perfect upload speeds on both the host and client machines.

The same problem persists when a NIC is directly passed through to a client machine and is persistent across all VM’s regardless of OS

The host hardware was used previously with no issue

Steps taken so far with no improvement:
  • Verified full GbE connection between switch and host
  • Changed NIC and cables
  • Re-Install of PVE
  • Directly passed a wireless intel nic to multiple VM's, same issue
  • Directly passed a Realtek wired nic to multiple VM's, same issue
  • Changed MTU size (its back to 1500 now)
  • Added pre-up ethtool -K enp39s0 rx off tx off to network interfaces
  • Added processor.max_cstate=1 to grub
The last three were buried in some forum posts so I tried them.


I also have pasted below some information that was requested in other posts

I know it's going to be something with the host machine, I just don't know what...

Any help would be greatly appreciated as I really did try to learn and solve this on my own, however I just don’t think I am quite there yet.

Thanks in advance,

Mort

i hate to state the obvious, are you completely sure it has nothing to do with your install, and not the network, or some element of it. Is it different result with same wireless and ethernet as the proxmox when using your pc?
