Hi everybody

I spent days trying to get my Alfa AWUS036H work with
Wireshark on Arch
Linux. It captured all sorts of fancy protocols, but no tcp.
I booted
Kali
linux on the same PC and followed the same procedure for data
capture
and
this time everything worked. I could see http requests to
multiple wifi
access points nearby.

After some more googleing, I think the problem is with the
rt2800usb
driver
on arch. I read somewhere that kali comes with a 'modified' wifi
driver for
capturing tcp data. I was wondering if its possible to
somehow get
kali's
driver working on arch? any help would be appreciated!

Regards

The Alfa AWUS036H should use rtl8187, not rt2800. Try it, and
see.
I remember the Alfa card having issues with Arch a couple of
years ago,
but i never got around to reporting the bugs...

Can anybody here tell me how to make Arch use rtl8187 driver? Using
'modprobe -r rt2800usb', I removed rt2800 driver and loaded
rtl8187 module,
hoping that kernel would automatically switch to rtl8187 but it
isn't
happening.  Regards.


Try blacklisting rt2800 via /etc/modprobe.d/ and reboot.


Upon blacklisting rt2800usb driver, the WiFi won't come up. 'lsusb
-t' shows
that there is no driver loaded for Alfa AWUS036H on boot. Later, I
manually
loaded rt2800usb module to get the wifi working. So no luck
getting the
module working with rtl8187 drivers.


You don't have an ALFA AWUS036H if it works with the Ralink driver.
I'm
100% sure of it.
You might have the 036NH model, that does use Ralink. In this case,
you
should talk to the pople at aircrack-ng.org, they might have some
backports that are patched for TCP.

Once again, the ALFA AWUS036H card is supposed to have a Realtek chip
and use rtl8187. I'm saying this because I've had three so far.


I may be wrong but I believe I have an AWUS036H device. I just
checked the
box the device came in. It says 'AWUS036H'. The sticker at the
bottom of the
device reads 'AWUS036H' as well.

'airmon-ng' says the Chipset is Ralink Technology, Corp. RT2870/RT3070.

'dmesg | grep -i usbcore' says 'usbcore: registered new interface
driver
rt2800usb'.

According to the store I bought this device from, the chipset is
RT3070L.

Since you had personal experience with these devices, I believe I
must give
rtl8187 drivers a try but I can't get those drivers running with this
device. The drivers are already installed but I dont know how to
make the
kernel use rtl8187 drivers instead of rt2800usb.

FYI, I contacted the guys at wireshark and aircrack-ng. Hope someone
will
respond soon.

Really appreciate you help.


Even the Alfa website says the chip is rtl8187. I don't know what you've
got. http://www.alfa.com.tw/products_show.php?pc=34&ps=92
With Arch we can't help you because you need modified drivers which Arch
Linux doesn't officially support. Though someone with more info might
reply.

Best of luck! I hope someone from aircrack gets back to you soon. They
know their stuff.


I also checked ALFA's website and found rtl8187 there. Both Arch and
Kali systems at my end say that my device is Ralink 2800 type. Funny
weird world.

A while ago I learned that both an original and a fake version were
circulating.
http://www.cyberprogrammers.net/2015/02/the-difference-between-original-and.html

perhaps this could be the reason.

It seems like I have a fake Alfa AWUS036H with Ralink Chipset. Anyway, I dont think the problem is related to hardware since Kali system can capture TCP data with this same adapter.

For future me and others who may be looking for such information, Kali is using libpcap 1.6.2, aircrack-ng 1:1.2-2-rc2, and wireshark 1.12.6. I managed to install these exact versions on Arch.

So now I have the same versions of wifi driver, airmon-ng, wireshark and libpcap on both systems but still no TCP on Arch. :|
