fluxion crashes

If the current behaviour is a bug, please provide the steps to reproduce it.

What do you think the expected behaviour should be?

Unable to start captive portal when use my external wifi adapter, my adapter is tp-link tl-wn722n v1 (AR9271), and yes it supported monitor mode, mdk3 aireplay-ng and any other modules are working, but why when i'm trying to start captive portal, the application says that it's unable to start. But when i use my built in wifi adapter (actually it should be written as wlp3s0, but in this time it didn't showing up, need to restart), it works, captive portal started.

Well if internal adapter is working then I guess external adapter has some driver problem.
You can try installing firmware for atheros chipset
apt-get update && apt-get install firmware-atheros
Plug your adapter and try running fluxion again.

[MPX4132]

I agree with @usama7628674, it’s likely a driver issue with your wireless hardware.

[haloohooloo]

I have the same problem I'm using Kali linux and my external adapter is Alfa AWUS036ACH / 88XXau Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter.

[salah2bebop]

@haloohooloo did you find a solution? i have the same adapter.

[cjb900]

@salah2bebop you do realize this was closed and is from like 3 years ago. If you did any type of research on the AWUS036ACH you would see that the chipset it has does not support VIF. Meaning that it will not work with fluxion by its self. You would have to have a second adapter to use along with this one to properly use fluxion.

[salah2bebop]

@cjb900 thanks for your reply, can you tell me what kind of adapter should
I have?

Well if you want to only use one adapter then you have to have one that supports packet injection, monitor mode, and AP mode. it also has to support VIF(virtual Interfaces) if you don't mind having 2 adapters then you can probably keep that one and just get another one so one adapter is deauthing and the other one is creating the fake AP. Here is a list of known good adapters and chipsets.

Atheros AR9271 <- present in TP-Link TL-WN722N v1 or Alfa AWUS036NHA (2.4Ghz - USB)
Ralink RT2770 <- present in Alfa AWUS051NH (2.4Ghz/5Ghz - USB)
Ralink RT3070 <- present in TP-Link TL-WN7200ND or Alfa AWUS036NH (2.4Ghz - USB)
Ralink RT3572 <- present in Alfa AWUS052NHS (2.4Ghz/5Ghz - USB)
Ralink RT5372 <- present in D-Link DWA-137 (2.4Ghz - USB)
Ralink RT5572 <- present in Panda PAU09 (2.4Ghz/5Ghz - USB)
Realtek RTL8723BE <- present in Realtek RTL8723BE card (2.4Ghz - PCIe)

Thank you very much for tout reply.

you do realize that you are posting a comments on an issue that has been closed for almost 3 years. Also may be if you did any research you would know that your issue is the card you have is not supported for wifi having which is why you are having issues. there is no one that can help you other than tell you to get a new card

[oussamajad]

download the driver
then open up include/autoconf.h
look for #define CONFIG_CONCURRENT_MODE and uncomment it by removing the double forward slash
or add it

define CONFIG_CONCURRENT_MODE

after that, build the driver then install it
make && make install

Anyone with the solution is most welcomed...please help me out(I'm using TP link v2/v3 adapter)

[cjb900]

@zebdev786 if your adapter is the TP-Link TL-WN722N v2/3 there is no solution. The chipset in that adapter does not support the proper modes to work in fluxion by its self. You would need to either get an adapter that supports monitor mode, AP mode and VIF or a second one to us with that adapter in fluxion

[zebdev786]

@cjb900 It supports monitor mode, packet injection and I can also create fake AP using it, then why it won't work?

[cjb900]

Because that adapter does not support VIF which is needed to be able to both deauth and create the fake AP at the same time. To my knowledge there is no way to give that adapter support for VIF. There have been many that i've seen try and fail to get that adapter to work by its self. You are just going to have to either replace that adapter with a know supported one or get a second one to use with it in fluxion.
