Speedstream 4100 different?

What IP address you use to setup your system the standard one that I use on the browser is 192.168.1.1 or 100. Try it and see if that will take you to it remember to keep your unit on.(did you try to connected via usb tell you do your update?) if not try to downloads another driver try this link and let me know. I will be working with you to conclusions of this issue. Please see that grant me your approvals by rating my service and I hope that I can serve you again the future.
