That will likely solve your dilemma.
I purchased a BD-390 a few weeks ago and have been struggling with getting the wireless video streaming to work properly. I've been on the phone with LG and with my ISP and neither have been able to help.
The problem is while I can configure the LG to access the internet (the test connection confirms I'm connected to the Internet), I am unable to connect to YouTube/NetFlix or CinemaNow. However, I can connect to Vudu and I have been able to stream a HD movie and watch trailers using Vudu, I can also connect to the other computers on my network (at least I can see their directories).
I've tried the internet connectivity with both Wired and Wireless with the same results. I have a 16Mbps cable connection from Comcast and although I do have VOIP and a few other computers on this network none of them are using any bandwidth while I've been trying to get this to work. I'm currently running Wireless G as my wireless network but when I ran a dedicated ethernet connection I had the same problem.
I'm on the verge of returning this but thought I would ask if anyone else has any ideas or suggestions before I do. Thanks for any help you can provide.
