I have put together a nice little music server / player with a B+, an IQAudio Dac+ and RuneAudio 0.3. Works beautifully when tethered to my network via ethernet but I cannot persuade it to connect via wi-fi. It will detect my talktalk network, allow me to input security details, but as soon as I hit "connect" it just starts searching for networks all over again. The wi-fi adapter was supplied with the Pi B+, uses a Ralink chipset and appears to be working (I have tested it successfully on a windows PC, and it illuminates when in one of the Pi's USB sockets). As an elderly novice to Linux, I'd be very grateful for any suggestions as to how to get wi-fi connected.
Thanks in hope,
