[End...OS] Can't get AP sharing on same wifi interface | Arch Linux Community | Page 1

Hello people, I'm struggling with the above. I can't get my Intel AX201 (does support AP modes) to share it's WIFI connection with my own hotspot AP. I've used iw to create an interface, made it go up using ifconfig, and somehow tried mashing this mess together with my NetworkManager to make it turn. Unfortunately, the nm reports that every interface but the one it selects is "device not ready". Due to this I reverted my changes and tried using nm to generate a hotspot (something I found out I can do only after making an interface), and that sort of works, I can't connect to my AP using any of my devices, and the AP seems to replace the WIFI connection I want to share.

#

Sorry for the edit! Hopefully I can find some help here :)

Most network interfaces can’t act as both a client and an AP at the same time.

#

It’s simply not possible on your hardware as far as I’m aware

#

... solved

I would still like to get some help trying to get WPA working since the only way I’ve found to get other devices to connect is using Enhanced Security mode

#

That’s pretty odd as far as standard goes

#

Unfortunate I can’t get a client and AP running simultaneously though

cursive quarry Oct 12, 2023, 6:06 PM

#

you can see if your wifi adapter supports being an AP and client at the same time with
$ iw list | grep -A3 'valid interface combinations'
for example, mine does:

        valid interface combinations:
                 * #{ managed } <= 1, #{ AP, P2P-client, P2P-GO } <= 1, #{ P2P-device } <= 1,
                   total <= 3, #channels <= 2

jovial wasp Oct 12, 2023, 6:07 PM

#

Hmmm

#

P2P is not the same thing though right

cursive quarry Oct 12, 2023, 6:07 PM

#

no it's different

My card does output that though

cursive quarry Oct 12, 2023, 6:08 PM

#

yours is exactly the same?

jovial wasp Oct 12, 2023, 6:08 PM

#

Yeah

#

I’ve been trying this for hours now lol

cursive quarry Oct 12, 2023, 6:08 PM

#

then it can be an AP and a client (managed) at the same time

jovial wasp Oct 12, 2023, 6:09 PM

#

Managed and AP?

#

Are you sure you’re reading that list right? It looks like it can only be managed and then nothing else

cursive quarry Oct 12, 2023, 6:10 PM

#

total number of managed not more than one, and total number of AP, ... not more than one, total number of P2P not more than one
total number of active modes at one time not more than 3, across no more than 2 channels

jovial wasp Oct 12, 2023, 6:11 PM

#

Hmmm

#

Okay this is very promising but network manager has refused to follow this completely

#

It doesn’t let me use two interfaces unless its en0p with wlan0

cursive quarry Oct 12, 2023, 6:14 PM

#

i'm not sure exactly what the problem is, but i have a script that i've used for hosting an AP before, if you want it

jovial wasp Oct 12, 2023, 6:14 PM

#

Yes

#

Please

#

🙏🙏🙏

cursive quarry Oct 12, 2023, 6:18 PM

#

📎 ap.sh 📎 hostapd_temp.conf 📎 dnsmasq-ap.conf

#

edit the network name and password in hostapd_temp.conf

#

you might have to exit other parts like the name of your wifi interface if it's not wlan0

jovial wasp Oct 12, 2023, 7:32 PM

#

#

This is the result, also no AP! I have a feeling this didn't work

#

                 * #{ managed } <= 1, #{ AP, P2P-client, P2P-GO } <= 1, #{ P2P-device } <= 1,
                   total <= 3, #channels <= 2``` Just to confirm, this is a snippet from my 'iw list'

#

Error: Failed to add/activate new connection: A 'wireless' setting is required if no AP path was given.```

#

I added -dd as a parameter to hostapd and it pushed through to broadcasting the ssid but I failed to connect

#

It's just a lot of nl180211

#

When it fails it looks like this: ... test: AP-ENABLED test: Setup of interface done.

this script is using iwd tools, not networkmanager

jovial wasp Oct 12, 2023, 8:05 PM

fair enough

should I just disable network manager

Disabled it, helped use the interface

#

Still can’t connect to the AP though

cursive quarry Oct 12, 2023, 8:09 PM

#

you might need to configure networkmanager to not manage the test interface

#

not sure, i don't think i had to

cursive quarry Oct 12, 2023, 8:09 PM

#

jovial wasp Still can’t connect to the AP though

does it create the network though?

jovial wasp Oct 12, 2023, 8:09 PM

#

Yes

#

Absolutely there

#

Im going to try a windows machine to isolate iOs

#

Its kinda quirky

#

Good news! The AP connects to the windows machine just fine

cursive quarry Oct 12, 2023, 8:11 PM

#

you might need to mess with the dhcp-range setting in the dnsmaq config, and try manually setting the IP address on the clients you wanna connect with (maybe DHCP isn't working properly)

#

oh that's cool

jovial wasp Oct 12, 2023, 8:12 PM

#

cursive quarry oh that's cool

Ye

#

But iOS is straight up telling me to go fuck myself

cursive quarry Oct 12, 2023, 8:12 PM

#

does the windows machine have internet through it?

jovial wasp Oct 12, 2023, 8:12 PM

#

No unfortunately

#

Im pretty sure network manager uses iwd as the backend but doesnt save any data inside so no ap for the internet connect

#

Windows says im connected but pinging the host machine results in “transmit failed. General failure”

cursive quarry Oct 12, 2023, 8:14 PM

#

could be DHCP issue

#

have you tried using only networkmanager? like for example the KDE networkmanager panel in systemsettings lets you create a WiFi AP to share internet

jovial wasp Oct 12, 2023, 8:15 PM

#

Have not

#

I use i3

cursive quarry Oct 12, 2023, 8:18 PM

this here's what it generates for me
File: /etc/NetworkManager/system-connections/share.nmconnection

do you mean nm-applet?

cursive quarry Oct 12, 2023, 8:21 PM

plasma-nm

#

but that will only be useful on kde

jovial wasp Oct 12, 2023, 8:59 PM

#

I think I’m just about ready to give up

#

I’ve tried using just iwd, resolvconf isnt working with it and ipados doesnt wanna connect and uhhh yeah im sick of this not working lol

#

AP works semi-reliably when its open

#

Thats about it

jovial wasp Oct 12, 2023, 9:00 PM

jovial wasp AP works semi-reliably when its open

Also dont you dare have another network connection
