I am new and hope I will make myself understandable and will post in adequation with the rules here :-)

I am trying to setup a wifi hotspot under Ubuntu 22.04 to forward internet from the ethernet connection. I can connect to the wifi hotspot with my phone, but the phone has no internet.

What I do:
Desktop PC under ubuntu 22.04 is connected via ethernet to my internet box and has internet. In the settings I turn on the WIFI, then turn on WIFI hotspot, with a WPA password, from there I connect with my phone, the phone connects to the hotspot but has no internet.

Checks I have done:

ubuntu is up-to-date
I have tested with the 2 ethernet adapters I have on board the PC: enp3s0 (Broadcom) and eno2 (Intel)
I have tested this with 2 phones, a Pixel under Android 12 and a Samsung under Android 9, both have no internet
I have set up in the same manner a hotspot with a laptop under ubuntu 22.04 as well following exactly the same steps and it works flawlessly for both phones

What I have tried:

Updating /etc/NetworkManager/system-connections with the hotspot address range
Turned off firewall: ufw disable
tried linux-wifi-hotspot: https://github.com/lakinduakash/linux-wifi-hotspot
Played with the routing tables: iptables -t nat -A POSTROUTING -s 10.42.0.0/24 -o eno2 -j MASQUERADE (inspired by How to create a Wi-Fi Hotspot (in Access Point mode)?)
edited netplan along the lines of Netplan config not working to rename one of the ethernet in eth0
added the hotspot IP range in /etc/NetworkManager/system-connections/Hotspot.nmconnection
downgraded wpa_supplicant-2.10 to wpa_supplicant-2.9 from Can't connect to ubuntu 22.04 hotspot

Maybe this helps, ip route returns:
default via 192.168.178.1 dev enp3s0 proto dhcp metric 101
10.42.0.0/24 dev wlo1 proto kernel scope link src 10.42.0.1 metric 600
169.254.0.0/16 dev wlo1 scope link metric 1000
192.168.178.0/24 dev enp3s0 proto kernel scope link src 192.168.178.69 metric 101

Has anyone an idea on what can be wrong?

Many thanks in advance

Hi, looking further, it seems to be a bug :-( https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1971538

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
