04 How To: Swap Comcast Modem With 3rd Party Modem And Activation 

You deserve a prize for not assuming that the viewer knows anything about the subject. That's the way to create a COMPLETE tutorial : assume the viewer knows NOTHING. Nice work, man !

Thank you for going through the steps one by one. I just bought a new modem and a new router, and I’ve been procrastinating because I didn’t know how to begin. Your explanation was the clearest one I’ve seen, and now I think I’m ready to give it a try. Thanks again.

I just swapped my self owned Arris 862 to a Netgear CM2050V. I was hoping it would just swap over and be done with some clicks. I ended up having to use my cellphone, which I recently registered with Comcast, and do the activation that way. It didn't just automatically open the web page and go. I also have a wifi router that complicated things. Once I finally got the modem activated and on line it wasn't connecting to the internet. I had to reboot the modem connected to my computer directly and it went online, then I had to figure out why the wifi router wasn't passing through the internet to my network for a while. I think I had to reset the automatic dns settings and then everything finally started working. If you're just going from the modem directly to the main computer it's a bit easier. Once the network was happy again the phone started working too but nothing just worked at first. I think you're directions on the video are fine but remember that stuff doesn't always play nice even when it claims to be on line and connected. You might have to reboot your computer and things a few times and double check or change some settings. For that you will need a cell phone that works with out your cable modem so you can get online and get it started like you did, then be able to search out solutions to the problems you might encounter if it doesn't work first try. For most users the first try like you showed works and nothing else will need to be done 👍

Great video! For some reason I thought the activation would be more complicated but that's incredibly straight forward.

Thanks bro. I had a old modem probably a good 12 years old and I thought I was going to have to call Comcast, I just followed the instructions and it worked. I gained 100 Mbps with the new modem.

Great Job! None of the other videos, same subject, have show how easy it is. Thank you.

Thanks for the info after dealing with trying to set up my modem with Xfinity for a couple of hours this got me up and running right away in 10 mins Good Job !!!!!

Very well presented and a good tutorial on how to make the swap from the Comcast to a personal modem.

Thanks for the demo. It’s the same instructions that came with my new modem, but now seeing it performed eases my mind and I know what to look for.

Thank you for this video. I just bought a third party modem router for xfinity. This really will come in handy when the modem router arrives. Thank You.

Thank you for your user friendly video on how to install a third party modem. Something we should have done years ago.

Nice straight forward video on the modem change task. Was having trouble doing so with new MG7700. Will start over after watching your video. Thank you.

Thank you!! This is exactly the video I am looking for because I wanted to replace my modem/router combo with my own while keeping the phone service

Great video. Straight and to the point.

an actual tutorial that is helpful and gets to the point thank you

Thanks for this! Much more confident at this point.

If I can't get this to work, I will be calling you directly. LOL

Great video. Straightforward, no bullshit. Thanks

You're the best. You've saved me $14 per month!

Thanks for sharing! … certainly better than calling them these Days! … Comcast should hire you to do their Installation Videos

Thanks for your video. I thought it would work just as you demonstrated. I'm tech challenged but now feel I can do this.

I don't get an option to activate anything third party...only to use the app which doesn't work for my new modem. Also have tried to set it up by calling them 3 times and they haven't gotten it done. It is a compatible unit.

Very cool step by step. any videos on the Night Hawk RAX 120 router?

Thank you for not trying to talk over old peoples heads. Even I understood that..

Nice job. I do my best to avoid xfinity customer service and do it myself.

Thank you! Very helpful to see all the steps.

Thanks for making this!

Great job! Awesome video! Very helpful!

Thank you.🙏🏽 It was really helpful.

Great job, thanks for the demonstration.

My experience was not so easy. I installed a modem/router combo and it drove me nuts getting things to work.

Thanks man, saved me a lot of time bro 👍

I knew you were from the Chicago area by how you talk and then I saw the 708 area code and yep! I used to be 312 then 708 now 630. Out of curiosity, did anyone call you? 😂

Thank you!

You Rock.

Really helpful, thank you!

thx. dude a useful video - am about to attempt this in a couple of days.....much appreciated

Nicely explained, thank you.

great video! Thanks

Thank you. I am going to try to switch out comcast modem for new modem

Thank you ... now, suppose you have a purchased XFINITY modem/router from ebay ... any thoughts ... suggestions ???

Thank You very much, this video is very helpful.

Very nice. Just one thing, though. Why didn't you say what brand and model of modem you were installing? I have the very same service, and it would've been great to know.

So, actually I was able to use xfinity box on each end of the coax. It worked slick. No activation. Set the second box to bridge mode from admin login 10.0.01 LAN. You will have to change your ethernet adaptor temporarily to make the change. Once that was done, vuola. Internet via 5g wifi. Superfast...too fast. My buddy's galaxy cell phone (J7) apparently has a limit of 55 gbs. My phone connected and downloaded at 140gbs in the same room as his. So I took it out, and put in my actiontec 3000 something or other. I only paid 20 bucks for the actiontec using FB marketplace. Have to say, it was my first time purchasing on marketplace and really worked well. At the end of the day, MoCA saved the day. Can't believe I never heard of it before. Save your xfinity box for moca connecting to a room with poor wifi and no ethernet cable. 1-2-3 and you are hard wired where you never thought you would be. It seems that when I was connecting I got the message that wi-fi connected buy no internet. I was impatient. Waiting 30-45 seconds eventually gave me the internet connection. If you dont know about MoCA, then you need to watch the videos here. Who knew that you could use coax as ethernet? Not me. Every home is USA with coax wall jacks now can have ethernet without going up in the attic or under the house. I have talked to network engineers, and they never heard of MoCA. Best kept secret in the world of networking.

Very helpful, thank you

Do you need to hard wire a computer with ethernet? My coax connection is in the living room and our wireless desktops are in other rooms. We would have an Xfinity cable box in the living room next to the modem/router.

Good vid, thanks

After connecting with the online portal with your PC desktop, did you have to call Comcast with the MAC address and serial number? Thanks.

I tried this but it never went through to xfinity setup. It says I'm connected to wifi but it won't let me go through the internet to activate my new modem.

ATTENTION ALL: New video is coming soon with another modem upgrade plus activation via mobile app!!

Go Bolts!

Video was really helpful. Question can I setup the xfinity wifi the first time without the app

So should I understand that the modem/router will work before you report what you're doing to Xfinity? I thought they had to push a button or something.

do you need to have a computer with ethernet capabilities for this? what if I just have the xfinity app?

Very help full thank you What modem is that if I may ask

Does your new modem also operate as a router?

Thanks!!

so, if i don't have a smart phone i can't get internet??

Tried connecting a surfboard sb8200 today and the Xfinity activation page kept saying it encountered a problem and to contact customer service....they said there was a glitch with thr system and an IT ticket had to be created for advanced troubleshooting.

In doing so, would this open up wall garden 🤔? So later internet doesn't drop or stop working

Got everything installed today. The router was the biggest problem, but the biggest problem was the idiot doing the installation...hooking the output of the modem into the output of the router??? Welcome to my world!

does it matter what coax port you plug it into or what kind of ethernet cable you use to setup the modem

hello, i have a question, do i need to have an ethernet cord connected to something in order to activate my 3rd party modem? I only have a laptop and a phone.

What if the router I bought does not have a port for the co ax cable my xfinity router does tho? Is this a problem?

Did you have to call Comcast to change the bill or anything?

Hey, you could easily block out your phone number in post-production. Might save you some headaches.

What if my computer isn't near my modem?

Thanks but I'm getting a different screen than you are when I plug the modem into my PC. There's no "Next" option and it just tells me to download the Xfinity app to set up the modem. (Which I can't do because the modem isn't a router) 😤😤😤😤😤 Edit: Figured it out, at the VERY bottom the the message telling you to install the app theres a link talking about Xfi for apartments. Click that and you can set up the modem with the PC.

5 OUT OF 5 STARS

I tried for hours to set up a new cable modem/ router to save money from Comca$t and they said it wasn't working...It must be Microsoft...! This modem was advertised for Comca$t! So we had to go back to the rental.....!

hello its me again :) So im thinking of buying the Nighthawk® DOCSIS® 3.1 2.7Gbps Two-in-One Cable Modem + WiFi 6 Router and Im using this modem to connect to Xfinity, then I wanted to connect a NETGEAR Nighthawk Pro Gaming AC2600 WiFi Router (XR500) to it. Does the modem I connect with Xfinity need to be just a cable modem to connect to my gaming router or can I use the Nighthawk® DOCSIS® 3.1 2.7Gbps Two-in-One Cable Modem + WiFi 6 Router with my gaming router?

Telephone 1?

So after all of this your next bill did they take off the rental fee for xfinity modem?

Word

Just a shame that my Cable Broadband provider in the UK pretty much has a monopoly and they won't allow you to use a 3rd party modem. So, I'm stuck with an Arris manufactured product that uses the Puma 6 chipset.

How many people have called you so far lol

Can i call you to comment?

5th video. let's see if someone can actually show me how to do this LOL!

One third party modems how do you change the WiFi name and password?

Show us how to wipe our s.

recorded with a potato

We dont have a cell phone and they dont offer a call back. Xfinity=Xinternetprovider
