That probably should be

Code:

sudo echo 1 > /proc/sys/net/ipv4/ip_forward

The possible values are 0 or 1 and you do not want to append to it.

I don't know if this adapter is capable of being an access point but you can test it via the command
sudo iwconfig <adapter ID> mode master

Should I proceed in terminal as follows?

Code:

iwconfig wlan0 IEEE 802.11 ESSID:off/any mode master

I'm doing something similar and you really need to set up a few things. Get the man page for iwconfig in one terminal and build your command in another. It's best to get a doc from your distro website and follow that.

Yes, for the Android device to connect over wireless the adapter needs to be capable of being an access point.

Results of test to find out if adapter is capable of being an access point using ID for inbuilt wireless adapter

Code:

sudo iwconfig <wlan0     IEEE 802.11  ESSID:off/any> mode master
bash: wlan0: No such file or directory

Are these examples from man iwconfig relevant?

Code:

Examples :
                   iwconfig eth0 essid any
                   iwconfig eth0 essid "My Network"
                   iwconfig eth0 essid -- "ANY"

I examined their Documentation nothing there had anything to do with 'how to use your inbuilt pc wifi adapter and share your vpn'.

Something else to consider, Network Manager has a builtin hot spot mode and if the VPN is already connected when started I would assume route traffic from the wireless. And also assuming your wireless adapter works in AP mode.

If you're on Debian, they will have many documentents on setting up an Access Point. Try a web search like

Code:

configure wifi access point

yes VPN is already connected on computer.

To check to see if my wireless adapter works in AP mode (access point mode) I used

Code:

iw list
wlan0     IEEE 802.11  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=off   
          Retry short limit:7   RTS thr:off   Fragment thr:off

If the hotspot works on windows doesn't that mean the inbuilt adapter is already access point mode compliant on linux too (on the same computer)?

https://linux-hardware.org/?id=pci:1...3b-3750&page=1

Code:

Linux 5.14.0-9parrot1-amd64 x86_64

Is 5.14 kernel less than a 5.2 kernel?

The output above shows that the Linux kernel is 64-bit and its version is 5.14.0-9, where:

5 - Kernel Version.
14 - Major Revision.
0 - Minor Revision.
9 - Patch number.

We are trying to establish:
- if my inbuilt wireless adapter is capable of being a access point
- if it is in access mode
- how to get it in access mode, and let all wireless devices go through the vpn on main computer (gateway hotspot)
- if we need manufacturer software drivers (worked fine out of the box under windows)

Post #14 We established that the inbuilt wireless adapter ID was:

Code:

wlan0  802.11  ESSID:off/any mode master

You confirmed that below:

I tried these combinations to no avail:

Code:

sudo iwconfig wlan0     IEEE 802.11  ESSID:off/any mode master
iwconfig: unknown command "IEEE"

Code:

sudo iwconfig wlan0  802.11  ESSID:off/any mode master
iwconfig: unknown command "802.11"

$sudo iwconfig wlan0  ESSID:off/any mode master
iwconfig: unknown command "ESSID:off/any"

We also haven't established if my kernel is beyond 5.2 as my builtin wireless adapter requires 5.2 kernel and beyond to function as a hotspot on linux (worked fine under windows out of the box). Here is my kernel details:

Code:

Linux 5.14.0-9parrot1-amd64

The article says if you got zero enter this:

Code:

$cat /proc/sys/net/ipv4/ip_forward  
0
echo 1 > /proc/sys/net/ipv4/ip_forward
bash: /proc/sys/net/ipv4/ip_forward: Permission denied

Does this sound right to you? Anything missing?

To configure inbuilt wireless adapter we need to:
- enable inbuilt wireless adapter's access point function (mode)
- broadcast SSID so wireless device can pick it up
- select from 1-11 broadcast channels
- enable/disable WEP
