I want to make a TOR router from my B+. If you have a experience in it, what is the best usb dongle for it? I have a lot of problem with my old RTL8191SU, so I need a replacement.
I recommend the Pi Hut's USB Wi-Fi Adapter, I have used it myself and it works fine with the B+. No set up is required it is literally plug and play. Here is a link to it:
I believe you can also get versions which support Bluetooth as well.
What is also important is you supply the Pi with adequate power, as USB Wi-Fi adapters can be power hungry.
