I had purchased Photon Whiz some months ago. It was working fine before providing a speed around 153 Kbps. But from last few days the speed is felled down to a great extent. I am even not getting a accurate speed of 50kbps. What should be done to improve the speed of the USB device. I have enough recharge in my modem also. What can be the reason behind this. The speed is now desperately fluctuating. Thanks in advance.
