Solving playback issues

[Moxie1]

All of a sudden several of my Roku Channels are pixelated.

HGTV, Food Network, Filmrise, etc.

Netflix and Acorn are ok

The channels has to reload.

I have tried the restart of Wifi, Roku, ETC

Nothing helps,

Used new HDMI cord.

Why all of a sudden?

Pixelization is almost always caused by a network speed issue. The Roku itself doesn't have a resolution below 720p, so it's not the display resolution causing it. Make certain you aren't having networking issues. Perhaps someone nearby has set up a new access point on the same channel you're using, and now you are getting interference.

Use a computer and go to speedtest.net and test your Internet speed. If it's under 10 Mbps, it's a possibility. If it's under 5, that most certainly would cause a problem. The question would be, what speed are you supposed to have and why is it not there?

You've suggested your Roku is connected to your home network via wifi.  Is your computer connected via wifi also, or is it a direct connection via Ethernet cable?

In any event, 1.5 mbps is too slow for reliable streaming.  It may be that other things on your network were also using bandwidth so that 1.5 mbps was all that was available for your speed test.

Try shutting everything but your computer down, run only the speed test on your computer, and try the test again.

Ethernet cable is connected to Router to my computer.

pixelation cleared up last night 

We will see

I need to see what Im paying for for speeds with Spectrum

Hi

Thanks for suggesting a Speed Test

I called Spectrum

They also tested and said my download speed very very low,

Trying to trouble shoot and visit 

We will see!

I am having the same issue. Just checked my download speed on the verizon tool and it says :

"Your router speed: 111/116 Mbps
A good result indicates that you are getting a result close to your subscribed speed.
The speed to your router indicates the total bandwidth available to all devices combined."

Since the pixelation is a new problem (and lagging loading times) I figure it's not my router that is the problem? I restarted roku, unplugged and replugged router, roku, tv... not really helping.

Thoughts?

@mblue2

Thanks for the post.

Have you tried switching out the HDMI cable as well as using another HDMI port on your TV to see if that resolves the issue?

For troubleshooting purposes, have you tried connecting your Roku device to another TV to see if you are seeing the same issue?

Please keep us posted and we will be able to assist you further.

Thanks,
Danny

@RokuDanny-R Thank you! I'm out of town but will check the cable when I return. Only have 1 tv, so kind of stuck there : )
