I recently changed my computer, router and modem. I now use HP computer with windows 8.1 operating system and uses Motorola SURFboard SBG6580 (modem and router combo). I have connected all former devices to the new network without problems with the exception of Roku M1001. It sees the wireless network but unable to connect to it. I have even reset it to the original factory configuration but still will not connect. Please help.
