    Re: static ip

    Don't forget chattr, for when files are being changed and you don't want that. For a few years right after resolvconf was introduced, I'd delete the symlink for /etc/resolv.conf, create a new file...

    Re: static ip

    I must be stupid.
    Some posts aren't labeled.
    I don't understand which outputs are for which configurations. Please CLEARLY LABEL which outputs go with which netplan config. Don't be afraid to...

    I've been reading through the entire thread 1 more time. I get confused because short answers that don't include the question being answered clearly are confusing.

    Re: static ip

    For networking to work correctly, 3 things are needed.

    IP address
    Subnet/Netmask
    Gateway IP


    Many posts ago, I asked to see two commands (ip a AND ip r) from a working config which would...

    Re: static ip

    - 192.168.25.3/24 to 192.168.25.1 using that subnet mask?

    That doesn't seem right.
    When you allow DHCP, what's the IP and gateway that works?
    Doesn't the gateway need to be in the same subnet as...

    Use --debug on all netplan commands.
    Remove the docket stuff.
    Stick with networkd as the renderer. Keep the netplan simple either using one that works on other systems or from a simple example...

    Re: static ip

    I think the problem is outside the computer, if you are 100% certain no firewall is in the way. Generally, desktop linux filewalls block inbound, not outbound.

    Re: static ip

    Well, without a renderer, I'm surprised that any IP is being provided that isn't DHCP.

    If you cannot ping the internet, then I don't see how any external DNS will work. BTW, it cannot.

    I'd like to know if this device can ping other devices on the same LAN/subnet. If so, then we assume it isn't a driver issue. Time to start looking external to the system - in other network...
