Well , I almost did not buy this thing due to some of the complaints I read on this forum. I must be blessed. Right out of the box I immediately upgraded firmware to 1.5 and connected with Belkin Wireless N, Verizon DSL (@3.2 KB/sec).
I have a constant 4 dot signal and the picture is good quality on my 47in RPTV. It has dropped twice in 2 weeks but each time it was the DSL and a restart of the Verizon modem brought it right back. All in all I am completely happy.
If you have not upgraded firmware, do it right away. I think Netflix and Roku had some growing pains and 1.5 fixed a lot of them . I only expect it to get better , especially if Roku expands the service.
