Hi,
I am still relatively new to Proxmox and I am actually using an old laptop lying around as my home server (hp pavilion i3-2350M and 6gb of ram with a 512gb ssd) and I am trying to have my server accessible at all times but the networking aspect of Proxmox has been nothing short of frustrating for me and I'm borderline throwing my laptop against a wall in frustration because for some reason I can't keep a consistent connection to my server for my clients to connect to (occasionally I am able to SSH into my server or access the web GUI through port 8006, but eventually it loses connection). These issues persist regardless of what client I try to access it from, so it's not a client issue by the looks of it. I made sure my firewall wasn't restricting anything either, both client side and router side. Here are all the situations I have encountered trying to set up networking on my server with varying levels of success.
1. Wireless connection via built in wifi adapter (at the time this was all I had access to)
I assumed I had it set up right in /etc/networking/interfaces with a static IP address in the config (left the laptop in DHCP mode on my router) and my subnet matched my router settings too. I restarted the network with "
2. Wired connection via powerline into my built in ethernet port (I do not have an easy way to directly plug ethernet cords in from my laptop to my router so this is my solution)
Again, set the configuration in /etc/networking/interfaces with the subnet and static IP and SSID/password as my wifi configuration (making sure my ip addresses do not conflict with one another) and all was well. I saw activity according to the lights from my ethernet port and I assumed it was working since it had an UP state. Same thing as the wifi solution where I was able to connect to the web GUI at this state. I was able to keep a connection for a bit longer surprisingly, like half an hour or so. I tried to upload an image to the server so I can create a VM for my server, but I walk away from my server for a moment to do other things, then I come back to find the connection was lost yet again. Frustrated, I went to seek what might be an issue but then I notice when I ran
My network controller is a Broadcom BCM4313 wifi adapter and ethernet controller is a Realtek RTL810xE ethernet controller if that also helps with troubleshooting. Also, with it being a laptop, I made sure to disable any sleep functions when lid is closed or screen is off, but with no success regarding connection.
TL;DR: Server can't stay connected to network at all times, regardless of wired or wireless connection; cannot for the life of me figure out what is wrong.

I assumed I had it set up right in /etc/networking/interfaces with a static IP address in the config (left the laptop in DHCP mode on my router) and my subnet matched my router settings too. I restarted the network with "
systemctl restart networking" and/or "ifconfig -a" to reset the networking and it says the state is UP so I assumed it established a connection to my network. I tried to connect to the web GUI and maybe one time it will let me connect into it but loses connection and if I try to refresh it, the connection keeps timing out. Same goes if I try to SSH from powershell on my client. This is where I kept looping around back to square 1 of trying to troubleshoot my issues till I gave up and tried a wired connection. Kind of weird considering the status still stays up yet it keeps timing out, even if I tried to reboot the entire server.2.

ip a again my ethernet connection refreshed but this time it was showing up a DORMANT status and now my port was just steady flashing an orange light. I verified it wasn't my hardware by using different ethernet cables (doubt cat 6 vs 8 would make a difference) and making sure the powerline adapters still work by using it with a different client (and it worked still). Did some research and it showed a DORMANT status which was looking like a power saving mode of some sort I assume. Could this be the root of my ethernet networking issues? It is odd that I have never seen my wifi connection ever showing a DORMANT status, only UP or DOWN.My network controller is a Broadcom BCM4313 wifi adapter and ethernet controller is a Realtek RTL810xE ethernet controller if that also helps with troubleshooting.
