USB WiFi Dongle Problem about stratux HOT 5 CLOSED

In fact, I think I know what the problem is. The Stratux DHCP Server doesn't provide the client with a DNS server.
Edit /etc/dhcp/dhcpd.conf and uncheck the option domain-name-servers 4.2.2.2; line, then run
systemctl restart isc-dhcp-server

Not sure if it makes a difference, I have not tested it, but:
1: Usually, the lines belonging to a specific network interface in /etc/network/interfaces are indented, similar to how it is done for the wlan1 interface.
Please add spaces/tabs in front of the pre-up/wpa-* lines, but NOT in front of the allow-hotplug/iface lines. Again, not sure if it makes a difference, but that is how it is usually done.

2: You must have Smart-Wifi option disabled for this to work. Note that when you change the setting, your /etc/network/interfaces file will be overwritten and you need to re-apply the changes.
[N.B.: the interfaces file is written from interfaces.template. If you want your changes to the file to survive wifi-settings changes on the web interface, you need to make the changes in there as well. However, that will then be reverted with the next Stratux update you do].

Done as per your recommendation (pic updated in the Google Drive link above for your reference) and still the internet isn't being forwarded.

It is disabled

I am now confident that this mod isn't working because even on the Reddit link that person posted it no one has confirmed it is. Would it be possible to direct me to a guide that is supported by you in order to have internet forwarding by a usb wifi dongle? This way I can at least try and ask questions in an area that has been verified by you and/or others.

I can't, because that's not a setup I use or have tested. But I am certainly experienced with Linux network configurations and the described setup is reasonable and looks fine to me - but its easy to forget some detail when writing such a guide.
With some Linux knowledge, it should be easy to diagnose the problem (e.g. check if the IP-Tables file looks correct (cat /etc/iptables.ipv4.nat), that the network interface config is fine (ifconfig), check the routing table looks ok (route -n), etc. But it's very hard to diagnose such problems without SSH access to the system.

Thank you! It is working now and I'm writing this message using the Stratux hotspot!
