Here's my problem I am experiencing a low performance on the wifi connection on my Vizio Co-Star, whether it is beside the router or located in another room. In wireless, I cannot stream any movies on Vudu and M GO. YouTube works, but it is lowered in low quality. I attempted a reset on the Co-Star and changed the wireless channels from my Netgear router. There was no sign of any improvements. A wired connection showed a sight improvement (according to the connection test). In both wired & wireless connection, I am not able to stream any movies from Vudu. My 9-year old son has a Vizio TV and wanted a Vizio streaming player to watch his Ultraviolet movies. His TV is located in a different room than our Internet router. So I cannot do a wired connection. What are the best ways to improve the wireless signal? Do I have a defective device? If so, should I ask for a replacement, or get a different device? Any input is appreciated. Thank you.
