I have a new Z83-4 and have installed the 1.66 BIOS. I use it in a kitchen as a TV access point for DirecTV (general use) and for Xfinity (live network channels from Denver.) The video is accessed via web browser, Chrome or Firefox. I have trimmed down the start menu to minimize load on the processor, and only open one browser to login to the video sources. Chrome and Firefox show the same problem. When watching any video, the stream constantly has tiny pauses and re-starts. A crawl across the screen on ESPN might hesitate 5+ times while one set of characters is moving across the screen. Full-screen motion video constantly starts and stops momentarily or for a few seconds, and every now and then stops to buffer for 30+ seconds. This does not happen on tablets or laptops used to view the same streams in the same room. The ISP is Comcast; the wireless source is an ASUS RT-N66U router with freshly updated firmware. The wireless system uses security so no outside users are connected to use bandwidth. I'm looking for ideas on how to get this streaming to work smoothly. The problem seems limited to the Minix, not to the system feeling it.
