[Solved] NetworkManager connects with no internet

New to arch here.

At home I can connect to the wifi with NetworkManger and all is fine. When I got to the office, I can connect to the wifi here, but I have no internetacces.
I then disable NetworkManger and enable iwd and connect through iwctl. Now I have internet access. How can I find and the fix this issue I have with network manager?

Here is the output from systemctl status NetworkManager if it help

Re: [Solved] NetworkManager connects with no internet

Please use [code][/code] tags.
But the slab there isn't gonna cut it - you seem to be connecting to some AP but there might be a DNS issue or whatever else going on.
See whether you can "ping -c1 8.8.8.8"
NM defaults to wpa_supplicant, are you https://wiki.archlinux.org/title/Networ … Fi_backend ?

In doubt please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: [Solved] NetworkManager connects with no internet

@seth Thank you for the information.

I ended up rebuilding the NetworkManger with iwd backend (from the link you posted), and that seemed to solve the issue for me.
I also had to forget the network and reconnect to it
