Siemens Gigaset USB Adapter 300

I was in class just the other day, when a classmate comes to me and says : “how would you like one of my usb wireless adapters, i don’t know if it’s still working or anything, but you can have it”. I was like, “sure”. I just got it today. As the title says, it’s a Siemens Gigaset USB Adapter 300. I didn’t even knew that Siemes makes wireless adapters. 

For starters, i just wanted to see if it works and if it supports packet injection.

I plugged it in, surprisingly the LEDs turned on. I was expecting it not to work at all. Here’s what dmesg said:

[   21.734320] Registered led device: rt2800usb-phy0::radio
[   21.734337] Registered led device: rt2800usb-phy0::assoc
[   21.734354] Registered led device: rt2800usb-phy0::quality
[   21.734390] usbcore: registered new interface driver rt2800usb

So we can see a ralink chipset (rt2800). I did an ifconfig and it was there as wlan3. I tried to connect to my wireless with it, via Ubuntus network manager and it was all good.

This adapter isn’t that bad. It can support data transfers up to 300Mbps and a range up to 50m indoors and 300m outdoors. I’m not that sure about the range, but i don’t think i’m really going to need it. I could barely find it on the internet to buy it and it was around 50 euros.

Ok, now for the packet injection test. I just googled that and you can do it easily with a tool from the aircrack-ng toolset. I restarted and booted my Backtrack5 and went for it:

root@hackcentral:~# aireplay-ng -9 wlan3
18:37:07  Trying broadcast probe requests…
18:37:07  Injection is working!
18:37:09  Found 3 APs

So it seems that it’s working and it can do packet injection. Nice. And it was free. I really have to put it to good use. I’ll probably write about that in the near future.
