Hi i have a interesting issue here
Testing to see if we can use a pi for streaming use at our school and for some reason when i use the NTP server on site it causes the wireless to essentially connect/disconnect continuously. with it off, it's fine.

we use a WPA-EAP and Ra-link usb wireless n adaptor

Raspberry PI type b
