I installed my Co-Star a couple weeks ago and have been uing and learning more about the device as time allows. In general, it is working as expected with the exception of the wireless network performance. I've tried to read through the threads here, and I do see the unusually low networks speeds reported by the Co-Star using its built in test connection diagnostic, so I use the built in test as a guide, but the browser test for a more accurate measure (I have been using Speed Test | Bandwidth | Broadband Internet Services). Network information on the Co-Star shows a 72 Mbps link with the router, the strength meter shows a solid signal with all parts of the strength indicator on solid (no fluctuation) and the signal strength at the Co-Star is -58dBm using the Wi-Fi Analytics app on my HTC Droid Incredible - this app helped me make minor adjustments in locating the Co-Star to get the best signal. I have FIOS 25/25 service. From my laptop, internet speed tests consistently show over 25 Mbps down and over 15 Mbps up (I will need to call Verizon about the upload). My phone shows better than 13 Mbps up and down (72 Mbps link). Under the best circumstances, the Co-Star shows 15-17 down and 15 up... best circumstances mean that I have the HDMI in cable disconnected from the device. I don't know why, but that makes a difference. I've tried several HDMI cables, and for my unit, disconnecting HDMI improves the wireless network download speed, but has no effect on upload. In fact, I found that I can leave the HDMI in plugged into the unit and turn off the STB power (making sure I disabled the FIOS screensaver so I think that means there is no HDMI signal going to the Co-Star when the STB is powered off...with the screensaver on, it does show a Veroizon FIOS logo when powered off), and this provides an improvement in wireless network performance over having the STB on. With the STB off, speed is slightly less that with the HDMI in unplugged, and it is also more variable...ranging from 7 to 15 Mbps. With the STB on, downloads drop to 3-5 Mbps in the browser speed test (and to about 1 MBps using the Co-Star diagnostic test). For what it's worth, I get 1-4 Mbps with the Co-Star test with the STB off, and 4-6 with the HDMI in unplugged. With the STB off, most streaming media is OK - Youtube, Netflix, etc, but some AVCHD and MP4 movies from my UPnP media devices are still not good. With the HDMI unplugged, these are better, but still not as smooth as when played off a USB drive plugged into the Co-Star (which looks great), so I believe the culprit is the network connection. My phone does not have enough horsepower for these HD video files, and they look the same streamed from the UPnP devices as when put them directly on the phone. On my laptop, the videos are fine streamed as welll as local - smooth as can be. I've tried two different routers, and the results are the same. Not sure if there is a good explanation for why I see the differences with the STB off and HDMI in unplugged - I have a support case with Vizio going on about this. Anyone else have any ideas or seen the same type of behavior. My interim solution is to use Plex for streaming my home movies since is does transcoding of the bitrate files to a user selected bitrate, but based on the experimenting I have done, I believe I should be able to stream this media without transcoding if I can get the wireless connection to work properly.
