Now, I currently have it connected to my on-board usb slot on the back of my case. The thing is, when I reset my machine, it doesn't pickup that the modem is connected to the USB port... I have to then hard reset my cable modem everytime I start windows... which isn't ideal at all...
I'm going to try ethernet see if that works any better I just found it strange that it used to work but only now since i've upgraded my machine am I having problems...
One possibility is that my mobo doesn't have enough power, SLI says minimum of 300w PSU which I think is an understatement... I currently have a relatively cheap 350w 24-pin ATX2 so could it be that I dont have enough physical power for the USB ports?
I hope i've answered my own question as a new PSU is relatively cheap in comparison to my new hardware.
Thanks in advance.
