Hello. I have a problem with Xiaopan 0.4.3b I'm running it on my laptop using boot from USB. Internal wireless card is Atheros AR9285. When I try to access to any of large amount of APs around me (about 20 different APs with strong signal), reaver constantly shows the same error: WPS Transaction Failed (code: 0x02) And trying the same pin over and over again. I tried to search for solution of this problem and the only thing that I've found is to use a lower version of reaver. There is Reaver v 1.4 preinstalled in Xiaopan 0.4.3b, so I wanted to install Reaver v 1.3 instead (from code.google.com/p/reaver-wps/downloads/list) . But unfortunately, when i try to enter ./configure command in src dir of the unpacked reaver-1.3.tar.gz , it shows me an error that "there is no C compiller installed in the system" or something like this (I can paste here the exact error contents if needed). So, the first question is: 1. How to install Reaver v 1.3 on Xiaopan 0.4.3b? Also, in case if there is a problem in my wireless adapter, not in the software, I have 2more questions: 2. If I buy a new wireless usb adapter, wich one should I chose to have guaranteed positive result (name a few models please)? 3. If I plug in a wireless usb adapter when running Xiaopan 0.4.3b, would it be instantly mounted and available for selection in reaver? If not, what commands should I type in terminal (or gui menus) to mount it? Thank you in advance.
