Ubuntu 24.04 hotspot

[gian2]

Hello All,

I would like this Ubuntu instance to work as a bridged hot spot.
I am using a Dlink USB radio, which is correctly detected with lsusb:

Bus 001 Device 002: ID 2001:3d04 D-Link Corp. 802.11 n WLAN

However, when I open the wireless setup, the hotspot option is greyed out, which makes me think that the OS thinks it's not capable, bridged or not.
This is not true, because I have two other Raspberry Pi working as AP on Debian, with the same hardware...

Any idea?

Thanks for your advice,

-Gian

Investigating the differences between the Raspi and this Ubuntu 24.04 station, I see that iw list returns ...

this for the Raspi
Supported interface modes:
* IBSS
* managed
* AP
* AP/VLAN
* monitor
* mesh point

this for Ubuntu 24.04
Supported interface modes:
* managed
* monitor

So the same USB is read in a different way.

"iw reg get" will show you wireless card capabilities

Are you in Italy? If so "iw reg set it" to set the appropriate regulatory domain and try again.

Thanks.

Yes, I was looking for a setting menu but there is no way to enter that on the desktop.

I have no problem on the command line but, as I installed the desktop I kind of expected to be able to do it from there.
