How do I chang the channel of frequency on my wireless adapter on my desktop computer. I and using the Rosewill RNX-N600PCE, Dual Band Wireless N600 Wi-Fi Adapter. There is a utility that it comes with that would allow me to change the channel but the area to enter it has become faded and will not allow me to change it. I have tried re-installing the driver but it still does not work. I am on windows 7 64 bit. Thank you for helping.
