I did and it made a great difference in a two story house. DL speeds
much faster with same ISP. Buffering stopped. All in all it has been
a significant improvement.

Huge improvements. You can get them in 3 or 6 pack and spread it out your house.

them to do it with initial install?

If you have an xFi compatiable router, then all you need is the pods to plug it in to the outlet and program it via your smartphone app.

Netgear Orbi Mini 2-Pack AC2200 Tri-Band WiFi System


If Comcast comes to my house, they are going to install THEIR modem and router, is it 2 pieces, one? Do they then refuse to touch my Orbi if I have it there and then that is for me to figure out and do? I could figure it out or get help, I just am not sure what is what with Comcast installation.

Thanks.

I see there is a AC2200 and an AC3000, the former is on Costco for less money, will it work just as well for a 2000 sq ft home as the AC3000?

Streaming 4k video reliably takes 16Mbps so, IMHO, 50Mbps would be barely adequate.

Can I ask why you want stream 4k over wifi?
It seems to me that watching in 4k would take place on a large flat fairly immobile flat screen TV. Why not spring for Ethernet cables? Wifi is subject to interference from motors (fans, vacuum cleaners...) and other appliances like microwave ovens.

I guess I'm just old school.

But doable, for sure.

Right now since I have a Samsung 4k and they do NOT stay connected via WiFi, this is a known problem with their entire TV product range and as far as I am concerned must be also with fridges, washer/dryers (Just gonna assume so) so hard wiring is necessary if I dont swap it out for an LG OLED.

To compensate for it I use ROKU when the TV wont stay connected.

If you are close enough to where your local line meets up with all the other lines, you will have full speed. If you live further away, not so much. Also, if your neighbors are chewing up too much bandwidth, you all slow down.

Basically, it's an escape for their benefit if your service does meet expectations they promised. I know that Comcast in my neighborhood sucked and complaints were completely ignored. They sent a guy out once and he was totally useless. I'm very glad to be rid of them. I'm certain that other areas may be just fine - I live in an older neighborhood and the local Comcast employees do not care about quality.

Which is why I am getting a higher speed than I know I need, I assume I wont get it or assume it is very possible.

Thanks.

As to using someone else, my choices are ATT using the same system offering a MAX of 50 or something called Sonic I think which is equally low on speed offer.

Would love another real choice and dont understand why ATT isnt faster.
