I bought my unit refurbished about three weeks ago. Spent the first two weeks trying to get it to consistently stream Netflix and hold the connection. I'm guessing I spent no less than 20 hours of trouble-shooting the first two weeks. Also, the first two Blu-Rays that I received from Netflix were Universal Studios films, and they'd sometimes work, sometimes not. I have 2.09 installed, and have taken every step (about 10 times) to download the 2.07 firmware and install it. I've tried the CD/iso route and the USB/.ruf file route. I get that 'error in update date' message others are getting. I can, however, install 2.09 on the machine, using the same methods. I've tried every setting, tried every published way to connect via wi-fi, for the first two weeks and nothing consistently worked.
Then, all of the sudden, my connection is solid enough to watch most every movie uninterrupted. And I'm 2-for-2 on my last two Blu-Rays. I'm not sure what I did that finally did the trick, 'cause I did the same thing about 10 times each. I think having re-installed 2.09 about 6-7 times might've done the trick. I'm also inputting the DNS directly on the machine (vs. 'auto'), but I tried doing that the first two weeks with little success, so not sure that's the trick that's doing it now. I've also changed my BD Live settings to 'all.' The first 5 or so times I tried this, it didn't work with a Universal Studios BD. On the 6th or 7th try, it did work.
At this point, I can do three more things: don't change a thing and hope this connection continues; 2) run ethernet/powerline ethernet for a slightly more consistent connection to the Internet or 3) wait for the 2.10 firmware, hoping that Samsung actually is listening to the problems from 2.09 firmware users and has fixed the problems. I have about 70 more days before my 90-day warranty expires. If I were to update to the future 2.10 update, there's no guarantee I'll be able to downgrade back to 2.09, though. Doesn't work for me from 2.09 to 2.07.
No need to respond with the usual suggestions (re-setting, unplugging and pressing the power button, checking checksum on the download files -- I've tried everything that I've seen published. It works for 2.09 installation, doesn't work for 2.07. Like I mentioned, the unit (for whatever reason) is working all right at this point (I get disconnections, but not every 5 minutes).
Has anybody who has had trouble installing 2.07 (from 2.09) ever found a new, unpublished way to actually get it installed?
Thanks in advance ...
