Hello

Proxmox newbie here I just installed a fresh bare metal PvE on a Lenovo m710q tiny.

Network settings:
- gateway: 192.168.1.1
- DHCP range: 192.168.1.100-200
- PvE IP range: 192.168.1.32-63

PvE becomes unreachable every five minutes if I don't interact (webui, ssh...) and I have to ping it to wake it up: usually the first ping gets a time out and after only I get a ping and everything works fine for a while

Physical eth slots look fine (orange led, blinking...), I changed the eth wire, when the server is awake everything seems to work just fine.

As it looks like a sleep issue I fully disabled systemctl sleep using systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target but to no avail.
 
Ok I answer to myself: I just realized I have an Intel I219-v NIC with e1000e driver... I tried to ethtool -K <nic-id> tso off gso off but it didn't work.

I have the latest kernel by the way: 6.5.11-8-pve
 
Problem NOT solved but I eventually proved that my issue is not entirely proxmox related : my home router-modem is a huawei b535-232 4g box managed by my internet access provider. I tested my pve server on a fiber network and everything worked flawlessly. The weird part is that i have an old synology server behind my 4g box and it's been working like a charm for years

The question now is why is that 4g huawei router providing inconsistent connection to my pve, and is there anything I can do to solve my problem ?

After a full debian bookworm + proxmox ve reinstall I figured out that the problem is most likely related to the bridge vmbr0 related. I prefer to close this thread and start another one from scratch with my current issue in the networking section.
