ERROR: 'wlan0' is not a WiFi interface

[zhangela]

Got this output when running create_ap:

create_ap wlan0 eth0 Kathmandu
ERROR: 'wlan0' is not a WiFi interface

Here's my iwconfig output, what arguments should I be passing in?

$iwconfig

[NicoHood]

how about using wlp3s0 then?

[zhangela]

$ceate_ap wlp3s0 wlps30 Kathmandu

[NicoHood]

you have not installed all dependencies. Please read the readme again or use a proper package for your OS.

[zhangela]

Sorry! Installed all the dependencies and still seeing error.

       Try again with --no-virt.


Doing cleanup.. done

[NicoHood]

do what the error suggests

[zhangela]

Tried that, didn't work either.

$ sudo create_ap --no-virt wlp3s0 wlp3s0 Kathmandu 
ERROR: You can not share your connection from the same interface if you are using --no-virt option.

[NicoHood]

Maybe you should read the readme and the help page first. Please close this issue as this is not a problem of the software. I am not the maintainer of this software, but I suggest you to search help somewhere else and learn the linux basics, as this has nothing really to do with the software itself. Please read the error and try to solve your problem first. Everything is covered in the help pages anyways.

[zhangela]

Just because I made 1 mistake earlier with forgetting to install the dependencies doesn't mean you get to be as condescending as you are.

I'm sorry if you or the maintainer built this for linux experts only, but I hope you do realize there are programmers out there who might not know everything in and out, and if you don't want people to file issues when they get stuck, maybe you should provide another channel to ask for help.

Also, let's be real, you are only being condescending right now because you have no idea why running it with --no-virt and without isn't working and you don't want to admit it.

Don't be a dick just because you are on the internet.

[NicoHood]

You specified the wlan interface twice (that is waht the error clearly says). You need to use the wlan interface and then the ethernet interface. Thatswhy it is possibly not working.

What is the brand and model of your adapter? It has similar interface combinations with the Raspberry PI 3 (see issue #203). Probably your adapter doesn't support virtual interfaces. I will investigate this issue with rpi3 the next week, but the fix will be only on the ruby branch, since I'm rewriting the project.

For now you can only share with different interfaces. Either from your ethernet adapter or with another wifi adapter.

To share via ethernet adapter do:

sudo create_ap --no-virt wlp3s0 enp13s0 MyAP

This issue will remain close since it's duplicate of #203.

PS: Keep in mind that this tool is created in our free time in our busy schedule. We see it as a hobby.

Thanks for your help!

This is ubuntu installed on a macbook pro, and I think this is my wireless card:

Thanks. I will buy a Broadcom usb adapter soon and hopefully I will find a solution for this.
