i have a new proxmox install. i have setup several vm's which all get internet access. I can connect to the proxmox web interface but from the shell(for proxmox) I have no internet., using a wired connection.I tried to apt install -y wireless tools.
Any help would be greatly appreciated.

Can you SSH in?

Can you post outputs of ip a , ip route , cat /etc/network/interfaces?



Are you trying to install wireless-tools because you are using WiFi for PVE?

I wanted to use the wireless so I wasn't as restricted to where I put the proxmox box in my house. I can log into the web interface. It's just for a home lab nothing production.

Alright, so are you unable to e.g. ping 1.1.1.1 or why do you think you have no access outside?

(Please use the [ CODE ] ... [ /CODE ] enclosing tags.)
 
I think OP means to say he wants to ADD wireless Wi-Fi capability to his setup. I believe his wired setup works as expected (incl. Public internet) - but he wants to add WLAN.

I don't need to point out that this is a very bad idea. See here.
 
ok it's working now after a reboot. Will skip wireless and just mound server next to ATT box headless.

Thanks,
Jason
 
Good. Looks like you got it working. Maybe tag prefix the thread-title with [SOLVED], (upper right hand corner under title).
 
now trying to update pveam template images and get this.
Any help would be greatly appreciated/

Can you ping 1.1.1.1 from the same machine (please test when the conditions are the same, e.g. confirm you still cannot get your image returning "No route to host" and immediately then do the ping and post the result).
 
Also, can you provide more information about your gateway sitting at 192.168.1.1? What kind of equipment is this and did you ensure it does not include the static IP of your PVE host in the DHCP pool for a giveway to e.g. a random VM?

Can you check DHCP leases on your gateway?

It's an ATT box and the gateway should be 192.168.1.254

I changed that rebooted server and now its downloading. I still can't figure out how to make proxmox box get a dhcp address so i can just allocate a dhcp reservation to it.

Thanks again

That was your problem then.

Because here you have/had your gateway fixed as .1.1:

Code: 
# cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.245/24
        gateway 192.168.1.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

iface wlxa047d70071f7 inet manual

You need to fix that and then systemctl restart networking (or reboot).

This would not be recommended the way PVE was designed, but especially if you do not plan to have a cluster, you could just do away with the static and have:

Code: 
iface vmbr0 inet dhcp
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

If you have static assignment, you need to ensure that on the DHCP server (in your case the gateway), it will not give away that address as a lease, so exclude it from DHCP pool (e.g. limit it to 192.168.1.1 - 192.168.1.199 range only).
