So, here is the scenario:
after receiving a contract to pen test a network, I often start on the outsides. Find their wifi and try to crack it. I think that is more impressive a pentester who don´t have to enter physically the company, so this is my first try. After getting the keys using backtrack / pineapple / etc I want to use my phone to show to the company how insecure is to use protocols like pop3, imap, and some sites like facebook and other sites suscetible to cookies hijack.
My choosen tool is droidsheep, that runs on my Galaxy S3. but I need to improve its signal. So here is the question:
How can I improve my wifi signal on a galaxy s3 (or another android phone)?
Found this tweak app rubberbibpepper.WiFiTxPower.3.apk that can boost the signal to 32dBm on android, but this is not enough. I have a pineapple iv and a fon 2100 coming (and a lot of linksys and cisco old routers) and a wifly city (alfa clone). Can I use any of these routers to connect my android and use their signal?
