Wireless Connected - Lan Shared From PC - NO internet

[stevenlutz1970]

Hi!

Ubuntu server 24.04 - Intel wifi 6 wireless card installed and connected to wifi - last resort test was to share my PC internet connection across the 10G switch hoping it would "grab it" - it did, and was assigned an IP address from the network sharing on the W11 PC, but neither the Ethernet nor the wireless are actually connecting to the internet.

I have removed cloud-init through apt, and disabled networkd in favor of NetworkManager.

Here are the two commands I remembered to copy, the results of nmcli, and the results of an attempted apt-update.

Please let me know if you need any more reports or tests.

Thank you!

file created and networkd disabled

/etc/cloud/cloud.cfg.d/99-disable-network-config.cfg

network: {config: disabled}

I should also state that wireless works on a clean install, but as soon as I introduce static IP address assignment to the 10G card, everything breaks. That is also when the p2p-dev-wlp3s0 makes it's appearance.

I found the answer - see netplan config:
