Hotspot cannot be discovered despite the application is running

[sith-on-mars]

I'm on Fedora 32.

I could create a hotspot on 2.4 frequency brand and the application said the hotspot was running. However, I couldn't find my hotspot at all on the network setting. I tried both on WPA & WPA2 Enterprise and WPA & WPA2 Personal network and the results were the same. Here is the screenshot of my settings:

Here is the command line output:
pkexec --user root create_ap wlp0s20f3 wlp0s20f3 'whatisahotspot' '' --mkconfig /etc/wh.config --freq-band 2.4
Config options written to '/etc/wh.config

Did I do anything wrong in the hotspot settings? Is there anyway to fix this? Thank you!

Does it work with a password?

Nope.

Sometimes it may be slow discovering of your device as in #69. Also, try with create_ap command line with multiple combinations such as enabling ieee80211n with sudo create_ap --ieee80211n wlp0s20f3 wlp0s20f3 MyAccessPoint MyPassPhrase

Thank you for your help. Please reopen this issue as the issue is not solved yet.

I have tried various create_ap combinations. They created hotspot successfully and I could find the hotspot and input the password, but I couldn't make other devices connect to the hotspot. For example, I tried to use my Android phone to connect to the hotspot and it stuck with "obtaining IP address". Here is an example command line output:

That's strange. I need to investigate more about this issue. There might be an issue with DHCP. Can you try to put a static IP in the client?

[sith-on-mars]

Can you tell me how to put a static IP in the client? I can't any tutorial on that.

[lakinduakash]

That's depend on your device. If it is android go to wifi setting and then select the network. Then you can select between DHCP and Static. Add gateway as 192.168.12.1 and assign IP addresses of your choice (must match to prefix/subnet) ex: 192.168.12.90

Sometimes it may be slow discovering of your device as in #69. Also, try with create_ap command line with multiple combinations such as enabling ieee80211n with sudo create_ap --ieee80211n wlp0s20f3 wlp0s20f3 MyAccessPoint MyPassPhrase

Refer here for more examples https://github.com/lakinduakash/linux-wifi-hotspot/blob/master/src/scripts/README.md

I had the same problem on Arch Linux where the tool would start properly, but my devices could not find the AP. I was able to resolve the issue using the suggested ieee80211n.

For reference, I now use the following command on Arch to create a working AP:

sudo create_ap --ieee80211n wlp4s0 enp0s25 apname secretpw

Thanks @lakinduakash for this package. It's awesome.

Nice!
I will add GUI option to enable that too. 😊

[lakinduakash]

@felixmde

I added GUI options to enable ieee80211n and ieee80211ac. you can check them. :)

After this, phone is stuck in "Obtaining IP Address".

Using static IP connects to AP, but doesn't provide internet.
