[SOLVED] Wi-Fi (Wi-Pi) dongle setup

Can you post a new dmesg with the new kernel?

Also, because of the rebooting, i have a strong suspicion that your adapter drains to much power from the RPi when reconnected. Most of the time, when altering WLAN settings, a replugging is need to make the changes take effect. So when the adapter is plugged in and doesn't work, it doesn't matter. But when you replug it, is start to work and thereby also draining power from the USB posts. So, indeed try another adapter that's more energy efficient or try to loan a powered usb hub.
