roku ultra intermittent internet disconect

i purchased a Roku ultra last night from Walmart to get the 20$ off promo
i hooked it up it seemed to work great, but when i went onto live tv, the box keeps losing internet connection every few moments. why is this?
i tried hard line Ethernet and WiFi but the same occurrence happens every few minutes.
this has never happened with my Roku stick, besides it getting hot.
my apple tv which is also an old model never has this issue either.
please advise

Re: roku ultra intermittent internet disconect

This has been an ongoing problem for me with Roku 3 and most recently with Roku Ultra using HD TV hardwired to Ethernet port. The system starts buffering (spinning circle) then loses Internet connection. Meanwhile, the Internet is still alive and running. Happens both during live streaming and playback. It usually reconnects after 5-10 minutes without intervention. Currently using YouTube TV. Any help would be greatly appreciated. Very annoying!!

Re: roku ultra intermittent internet disconect

I had this same issue over Wifi. I have 300Mb/s to the internet.   Looking at my router's connection to the Roku it looked as if the Roku's buffer was overflowing.  I believed this overflow was causing IP packet loss.  After much trial and error I enabled QOS (Quality of Service) on my router and limited the bandwidth available to the ROKU to about 7Mb/s.  This eliminated the disconnects.  I have not had an issue for several months.

Re: roku ultra intermittent internet disconect

I am having a very similar problem... Roku Ultra (Model 4670-RW) running build 9.2.0-4806 with Ethernet port connection on a 600Mb/s Internet connection.

It ran perfectly for a little over a month, then started in with the blackened screen intermittently that would show nothing then eventually we would see the spinning loop for a few seconds and ultimately the bouncing Roku logo comes up.  After a few seconds of that, it goes right back to the channel/program we were watching/streaming.  Haven't noticed it on any live streaming, just prerecorded content.

The other odd thing is that it almost seems like it is trying to do an update, but can't start it for some reason.  I check the auto-update screen and it seems like it is not updating (date is way behind current date).  Just a bit ago, I checked it manually and an update was available (9.2.0 build 4807-46), so I've updated it now.  But I don't know when it became available, so I can't officially say there's something wrong with the update process within the device.  I shall see if this fixes it or not... Anyone  have this occur, along with the original intermittent reboots?  TIA.

Re: roku ultra intermittent internet disconect

I had buffering issues recently on my Roku ultra but my other two TV's use the Roku stick which work perfectly.  I could not understand why the wireless Roku's had no buffering but my wired Ultra was buffering like crazy.  Luckily the Ultra allows ethernet or wireless internet connection so I changed from wired to wireless and no more buffering???

I'm guessing the Roku uses a larger buffer size when you select wireless vs wired.

Re: roku ultra intermittent internet disconect

Smcvey,

I responded yesterday to this, but I think it did not post properly for some reason...

As it turned out, the problem turned out to be the Roku Ultra (RU) itself.  I determined that by swapping RU boxes - I have another in another room / TV setup - and the problem moved with the RU.  Swapped back to initial setups, and the problem again moved with the suspect box.  I still had some warranty left on the bad unit, and I turned it in for a replacement.  The problem then disappeared completely / was resolved.

Good luck!

Re: roku ultra intermittent internet disconect

Good to know.  I suppose my ultra could  have a defective ethernet port but I only have 1 ultra so I can't just swap it with another.  And it's out of warranty. 

I have not seen buffering since changing to wireless so I'm keeping my fingers  crossed.
