Hi:

I have a Nighthawk R7000 +Arris Surfboard. When I watch HD/4K Netflix on my TV, my Tablet download speed slows significantly.

I have Xfinity Blast which is up to 300 Mbps. Actual speeds always around 50 Mbps. Will this Mesh X6S Tri-Band Extender speed up my Internet on my Tablet while watching Netflix on TV?

Thanks

Should be fine. It's a docsis 3.0 with 16x4 channels or a maximum throughput of 686/131. I'd contact Comcast. Hopefully it's an easy fix on their end.

If they need to send a tech out, they will probably charge. There's a few things you can check before then. The main thing a tech is going to be looking at is signal strength and line noise. You can reduce line noise by ensuring you're not using sub standard cable and you use the minimum number of required splitters for your house. If there isn't a TV plugged in to a line, that line shouldn't be connect to a splitter. Ideally the splitter has the exact number of connections you need. If you have any extra ports, use a 75ohm terminator. Next you can check you signal strength using...

I doubt it will help unless you have signal strength issues. Have you tested your bandwidth to ensure you're getting the 300Mbps you're paying for? Be sure to test using a wired connection to eliminate any potential wireless issues that could be squeezing you bandwidth. Which surfboard do you have?

Hi smashjohn:

Thanks for the reply. When I check my internet speed on my wired PC it's consistently around 50-55 MBPS. Is that the problem? I only have 2 devices connected. The Xfinity price is $109 p/m.

Thanks

If the issue is with Comcast, they won't charge. But if they need to replace any splitters, or adjust the DB w/ installed equipment, they usually charge for that.
