Help with phone as modem

[nolo25]

hey can someone plz help me. I have been trying to see how I can connect my phone to ps3 through internet sharing. I have wmwifirouter and the fixed cab to internet sharing but when I connect usb cable from phone to ps3. phone says check the usb connection (from the internet sharing program). The wifirouter program says waiting for connection to ISC. Please someone help I been trying to do this for a few days and been getting frustrated wit this. I use my ps3 for updates, browser, and online gaming. If someone can help that would be grately appreciated
Thanx in advance.
