Hi All

So brand new to Proxmox. Now Ihave just installed version 6.0 (twice to make sure I wasnt going crazy).
I have no internet and I cant ping my gateway. This also means I cant access the web interface

Now this question has been asked a few times but I have not been able to get any fix to work for me.

My /etc/network/interfaces is
Code: 
auto lo
iface lo inet loopback

iface enp14s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.81
        netmask 255.255.255.0
        gateway 192.168.1.1
        bridge_ports enp14s0
        bridge_stp off
        bridge_fd 0

When I originally set it up, I set my DNS to 8.8.8.8

When I try ping 192.168.1.1 I get "Destination Host Unreachable"

When I log into my router I can see the computer show up there, but I cant ping it from my main computer either, I just get the same "Destination Host Unreachable" message.

Does anyone know what might be going on here and how I could fix it?


(Here is a photo from the first install, I had it on another IP, hence the .79 instead of the .81 which I am currently on)

@t.lamprecht The laptop is connected by ethernet to the main switch (Same one that my main PC is on right now)
Here is the output

Code: 
ip route
default via 192.168.1.1 dev vmbr0 onlink
192.168.1.0/24 dev bmbr0 proto kernel scope link src 192.168.1.81

and here is the output of the other:

Also here is my working Windows PC's network setting for refrence:

Hmm, looks all as it should.

Does the info comes from a DHCP server on the network or did you entered it manually?
Just to ensure the network details are correct, not that it should be "192.168.0.0/24" or the like (sorry, stupid questions, but as all seems well else we need to ensure the basics :) )

Do you see (ping) the server from the outside? If you have another Linux box, you could try and ARP ping with: arping 1c:75:08:7f:77:d4
 
@t.lamprecht The info is all entered manually. It's definitely 192.168.1.1 as that's what I use in the Web browser to configure the router. Don't have another Linux box handy right now, but I tried to ping its ip from my windows box and it won't work. Ill see if I can get a VM booted up and try ARP ping it
 
So just an update, I reinstalled on another laptop and it works fine! So I guess its a driver issue or something strange with this other laptop
 
I mean glad that not all is broken but strange nonetheless. Could you post the
Code: 
lspci -knn

Or, if you cannot copy paste yet, the reduced info from the network only
Code: 
lspci -knn | grep -A 3 net
to see what network card and which Kernel driver is in use.
 
I would do this, but I had to the use same drive to re install on the other laptop. If I get time I'll reinstall it again on the old laptop and get you this information
