I was using a Roku premier on a couple different TVs and had a positive experience. I got a roku ultra and have had nothing but issues. Multiple channels are encountering issues (see details below).  The issues persist with wireless, and a direct wired connect. They persist on different HDMI ports on the TV and with different cables. Network tests from a laptop plugged into the same ethernet cable yield no issues with latency / packet loss.The issues persist after full cable router power off, roku unplug, tv power unplug, cable power on, tv power on, roku power on.

I plugged my Roku Premiere into the same TV (wireless only) and it seems to work fine (4620X 8.1.0 build 4159-29). 

Should I seek a replacement for the ultra?

Thanks in advance.

Any suggestions from all you experts out there?
I've seen some recent posts from others about Amazon Prime on ultra, not sure about other channels.

The post is tough to read with all of that HTML formatting in it but from what I can tell the only channel you are having issues with that I also use is Amazon Prime and I have had no issues with it on my Ultra.  I was having problems with BBC America crashing on startup every time in spite of multiple deinstall/reboot/reinstallations.  This problem went away with my upgrade to 9.0 which I got on Wednesday.

Have you tried uninstalling-rebooting-reinstalling the problem channels?
Have you gotten the 9.0 update yet?

Thanks. I’m not sure how the awesome html got in there.

When I try to update the software the update progress counter cycles up to 97 or 98% and then I get an error code 006. Unable to update software. The software update failed because the verification failed.

I tried it twice. Does not seem to be a happy unit.

Just got a Roku Ultra and cannot even configure the Roksbox channel.

As soon as I click on the menu it crashes and reboots the ultra.

App was just updated two weeks ago.

Also had crash issues when trying to configure my amazon prime account.

Mdahm,
Were you able to resolve the verification issue? I have tried everything I can think of but still get that error 006 when trying to update to version 8.2.0.4170.

I haven't been successful as of yet. When I got the unit it had issues doing the initial update. The resolution at that time was to power off roku/tv/internet router, then bring things back up. My next steps steps was to attempt that, but the family seems to always be using it. If I can get it upgraded I'll update the thread.

I left the ultra plugged in and it looks like it was able to update itself on 12/13 to 9.0.0 build 4083.

Network issues still exist. I removed the science go channel and reinstalled it. It crashes 4/5 times when trying to load and any type of navigation within the app if it happens to load will cause it to crash.

I removed the amazon music channel and reinstalled it. It has the same issues. Album art doesn’t load or partially loads. Music fails to stream and stops during a song.

Frustrating.

I'd replace the Ultra. Since it's been over a month, the store might not take it back. But, I was able to get Roku to replace a defective Ultra with relative ease. Get an RMA, return it, and they'll ship you a new one. They'll want to see a receipt.

Thanks - I sent a note to Roku support earlier today. Fingers crossed.
