I checked up on this. Your address is too far from the nearest Fiber Node (must be within 1/3 of a mile) and won't be able to get gigabyte service. At this time, there is no ETA to extend this out to your area.

Like a lot of people, I signed up the same day this form was made available (back in March): 

 

http://www.xfinity.com/xfinity-one-gig-signup

 

I've been waiting patiently for a response - Strangely enough, a friend who lives less than 2 miles away from me currently has Gigabit service in their home. Further, I live right above a new Xfinity store (Literally, the only thing between me and the store is about a foot of concrete and rebar). All the agents I've spoken to have told me that the 1 Gigabit service is available in my area, however, all of them have directed me to the same form I filled out earlier this year. Would it be possible to at least get a yay or nay on my ability to get this service - or will it continue to be radio silence? 

 

Thanks!

For that type of plan, it could use a higher upload speed along with it being not over $100/month.

Looking at today's plans I am a little perplexed at the logic of the comcast offering. Comcast business has offered 500/500 MB fiber tiers for a while. However now there is a 2gb tier for the same cost. There is no one gig tier in fiber despite docsis 3.1 gig service only offering 35 mb uploads? Why? What other major service provider does this? If you seriously think anyone would select docsis 3.1 over google, att, or fios you are insane.

Furthermore I have attempted to get the gigabit pro service in my area but no one knows anything. I would have liked to have gotten it during the $150 special but I could not even get comcast home or business to call back. Kind of like when I called about getting the box on the side of my house moved before attaching a garage. The customer service rep simply said I couldn't get a garage attached there and someone would call me. Needless to say I connected the garage there.

So I went out to the pole and the fiber and connection for the neighborhood is 300feet from our house. If connecting under the road is an issue, it wasn't when Verizon redid the fiber when the changed the road, I would farm out the conduit service and trenching for Comcast.

Anyway, it seems the only option is dreadfully uploads with coax. I also have serous doubts that comcast will EVER actually provide 35 up since I am currently paying for the 150/25 tier and I am being capped at 12 just like thousands of other customers.

So I signed up to get more information on gig service in my area (zip code 60514) and I have yet to receive a followup email weeks later. While reading this topic I noticed that others had a similar problem and that some kind Comcast/Xfinity folks were able to follow up. I would appreciate the same consideration.

 

I could really use gig service. Anyone know if it's getting rolled out in my area yet (or how I can check myself)?

Just got a call from Support. My gig-E service will be installed this coming Thursday (Nov 3). I'll let y'all know how it turns out.

 

BTW, I asked if I could supply my own DOCSIS 3.1 modem. Support said that none are available for purchase (I confirmed this with an Amazon search) so I'll have to rent. I'll be paying $200/month flat for the double-play service which is GigInternet and Xfinity-X1 TV.

My GigE service was installed this morning. To give you an indication how new this is, my installer said I was only the second one he had done.

 

The modem provided is a Technicolor TC4400-CMT. This is not available for retail (and as of this writing there aren't any DOCSIS 3.1 modems available retail). Additionally, they also provided a Netgear Nighthawk X6 wireless router. This router provides 802.11ac support (AC3200) and can handle multi-gigabyte wireless speeds. This stuff is all part of the $10/month rental. (If you have a working router with lots of services already enabled like openvpn then just swap back in your old router after they leave.)

 

Installation was as simple as replacing my SB1641 with the Technicolor modem and swapping out the routers (I had an ASUS AC-68U).

 

The installer tested the connection using a raspberry-pi device direct to the modem. Mine showed 940Mbps down and 42Mbps up. This is apparently as fast as it will go right now since there is (according to installer) some 60Mbps overhead, so 940 is max downstream.

 

Connecting my computer (wired) and running the speedtest.xfinity.com test showed 750Mbps down and 35Mbps up.

 

Service is running nicely.

 

There were a few bumps in the road that I'll document here. 

 

1. There are two ports on the Technicolor modem. Only one of them is activated, so if the internet link won't come up try the other port.

2. The Netgear router will not detect the Internet if the modem has already provided an IP to another directly connected device and then you move the cables. Even though the Netgear should get a new IP allocated and see to the outside, it doesn't work. You must reboot the router.

3. The safest boot sequence is as follows. One, boot the modem until it has negotiated its link. This is indicated by all lights turning solid green except for the link light. Two, power on the router. Router takes about 3-4 minutes to boot! The Internet light will remain amber colored until it negotiates a link to the outside. At that point, it should turn white to indicate a good Internet connection.

 

Make sure you update the router password. By default it is set to admin/password which is very insecure. The installer will make sure the firmware is up-to-date prior to leaving but it doesn't hurt to click the "upgrade" button anyway to make sure. Smiley Happy

 

Lastly, the installer made sure to tell me to check my datacap online. I mentioned that I heard there was NO CAP for Gig service but he couldn't confirm that. I'll post a follow up when I have confirmation one way or the other.

An older post, but that would depend on if you got the 3 year unlimited promotion $70 a month with $10 modem rental, which Comcast are offering in certain areas. If you didn't then it may be subject to the cap. I believe you can pay $50 a month extra to get unlimited, but if paying the full price, that would be pretty hefty.

 

From what I've seen lately, Comcast are being picky about who they offer the promotion to

I had my Gigabit Internet installed a few days ago.  (I'm living in suburban Chicago).   My experience was similar to what creme experienced above.  In my case two Comcast technicians came out.  One was a supervisor training another installer.  They rang the bell and said they needed to put new wiring outside before they did anything inside.  I mentioned that my levels as seen on my old Arris TG1682G administration page were perfect.  They said, "yeah but your upstream levels which you cannot see aren't good."   

 

About an hour later they began to work inside.  As creme stated they bring a Technicolor TC4400-CMT modem and Netgear Nighthawk X6 router.  The tech made a call to a mysterious private Comcast number and gave them my account information.  Before he learned anything he had to give them his Comcast employee ID, I guess to make sure it wasn't some pesky customer trying to self install.   The modem was activated and hooked up to the router.  A few minutes later he tested the Internet speed on my desktop connected by Ethernet to the router.

 

The download  speed zoomed up to 950 Mbps, upload was 42 Mbps.   Wireless connections were much less.  My Yoga 900 laptop gave me 452 Mbps when in the same room as the Nighthawk.  On the other side of the house it held steady at 170 Mbps.  My android phone in the same room connected at 240 Mbps.  Upload speeds on all devices remained solid at 42 Mbps.

 

Other thoughts:

Now I have THREE Comcast provided units for this service.  In addition to the modem and router, since I have Comcast Voice I needed to keep my old TG1682G gateway strictly for telephone service (the tech wisely turned off its radio signals without me having to ask.)

 

The Nighthawk router takes up ALOT of real estate on my desk.  It looks like some kind of extraterrestrial flying ship.  The Comcast tech before I could say anything mentioned that in his earlier installs other customers wanted to use their own routers.  He obliged and connected them up but NONE of them could equal the speed of the Nighthawk and he wound up installing one at each location.  

 

The Comcast techs who came out were very courteous and knowledgeable and made sure they answered every question before they left.

Hi 

 

I am interested in signing up for gigabit over d 3.1. After completing the form and a 2 month wait I was called by a sales agent offered 70$ per month unlimited data 3 year contract or 140$ month no contract with 1 tb cap. I said I would consider my options and they said that is fine give us a call back. When I called back wanting to sign up for the 70$ deal the rep said that was not available in my area. Now every time I call back it says thank you for calling comcast our offices are currently closed. It was 5 o clock on a monday night when I called the sales rep called me at 6:30 on a Thursday night. Am I missing something here? 

 

Thanks!

Just wanted to state my experience of having the 1 gig install done a few days ago.  I am located in Rockford, IL.  I filled out the form about 2 months ago and just now had it installed a few days ago.  I am getting 950mbps+ on the download and 40mbps on the upload.  It took about 2 hours for them to install it as they had to run all new cable to the modem to ensure that it has a clean signal.  They also replaced all of the connections on my cable boxes so they wouldn't interfere with the signal.  They gave me a Technicolor TC4400-CMT modem and I am currently using a Netgear Nighthawk X8 R8500 router.  If there are any questions feel free to ask them.

I just had this service installed also and at first it didn't go so well. After a second tech came out he ran another line to the modem however he still has the line going to a splitter outside instead of direct to modem is this normal? My issue is that my download speed is only 420mb which makes no sense. You would think it would be at least 750 or higher. I have same equipment as others on here. I already had a nighthawk router and didn't keep the Comcast one as it's same as mine. I am hard wired and using cat6 cable. So I am not even getting 50% of the advertised speed. I am in Chicago. For those that have a new line run direct to your modem did they add a splitter on the outside or did it go direct from pole right to your modem?

Sabre31 -

 

In my case the line comes directly into my house and then goes into a splitter with one connection to the modem and the other to the TV's in my home, so it sounds like it's basically the same setup you have.

 

I did notice that after my install my download speed was also around 420 Mpbs. as you are experiencing   I figured it was a Comcast problem, but just to be sure I bypassed my Nighthawk router and connected the modem DIRECTLY into my computer by Ethernet.  After rebooting everything  I was amazed to see my speed was the full 960 Mpbs!!   I realized the problem was the ROUTER!.

 

I hooked the router back in, connected by Ethernet as I was before, and the speed dropped again. I experimented with the router administration page for awhile. I discovered that the cause was that I enabled the Nighthawk's "Traffic Meter."   I disabled the traffic meter and I'm back at full speed with my router in the system.

 

Bottom line, to check your Comcast speed you need to bypass the router to see if it's causing the 'logjam"

Those with Gigabit Intenet, is anyone using an AC1900 Router (Specifically the Asus RT-AC68P from Best Buy)?  Curious as to how its performing, and how your wired/wireless speeds have been. Wondering if this router is suitable or moving to the RT3100 Asus is better.

Hi gizbug -

 

I think most folks receiving Comcast Gigabit Internet are sticking with the provided Nighthawk X6 router Comcast provides.  My installer told me that in earlier installs customers had asked to keep their personal routers, he hooked them up and none of them could match the Gigabit speed so each of them wound up using the Nighthawk.  

 

I don't think it's a bad deal.  Realize that for a 10 dollar a month rental fee you get the Technicolor Docsis 3.1 modem, a new X6 router which Best Buy is selling for 300 dollars, and if you have Comcast Voice, an Arris modem just for telephone service and if anything goes wrong with any of them, Comcast will replace them.

Alan, Thanks so much for all your help this worked. The traffic manager was the issue. So glad. I should have kept the Comcast nighthawk. I had same model but they had a brand new one in box. However I am hoping the installer properly removed it from my profile. When you check your Comcast account does the wireless router show up as an equipment under your account ?

Also are you guys getting charged double rental fee? $10/month for new gig modem and $10/month for old modem which still has my phone? I feel they should not charge for both as it's not my fault they don't have a docsis 3.1 modem with voip support yet.

Some systems, mainly the ones that don't let you have your own voice equipment don't even charge for the voice modem rental as long as its coded properly to tell it voice only. I think I know why you are getting double charged. If you bought into gigabit internet while already having an internet included in a package deal you still technically have the other internet package so both modems could actually be activated but one for gigabit internet and one for the older package.

I'm only charged ONE 10 dollar a month fee for all THREE boxes, the modem, router and voice modem.  You shouldn't have to call them, if you have Comcast Voice the installer should have taken care of what needs to be done.  Comcast won't charge you for an extra voice modem.   To be honest I don't care how they code anything.  That's their problem,   I know my old  Arris has had its wi-fi radios turned off and I'm not charged extra for it. 

And it's interesting.  My hardware listed online only shows my Technicolor Docsis 3.1 modem and the Arris Voice modem.  It does not list the Nighthawk at all.   I imagine somewhere it's documented that I have their router, so I'm not planning to sell it on Ebay anytime soon.

The traffic meter must be turned off and also the dynamic QOS. QoS isn't needed on a connection this fast and the processor can't handle the speeds. It's a limitation in every single router that has ever been sold.

Can you provide any technical contact information?  I've gone through the regular support channels as a result of losing HBO for no reason a few hours after my gigabit upgrade today.  There were a few delays getting the modem activated, but it finally did and the  tech took the old voice modem when he left.  Not that I used the phone service anyway.  Everything was fine for a few hours, but I noticed then that did not appear to be active on my account which it has been for years on a Triple Play package.  Regular support says they can't break it apart without lowering the internet speed and they have no way of contacting the gigabit support department.

 

Please help if you can.

 

Thanks.

Does anyone have any advice for me? I'd like to use the service but if I can't as I want to then, I'll stick with my old plan. 

 

Was presented to me as still being able to use my own devices (router included)

   - Comcast support indicated I was not allowed to, even though my device supports it (Cisco 2821 w/2x Gig ports)

 

I saw some people have their own Routers successfully hooked up to the modems, what gives?

Somj20 -

 

I have the gigabit service in Chicago.  Here they had no problem allowing me to use any router I wanted to, in fact the installer hooked up their Technicolor modem to my router himself. Unfortunately mine did not give me the full gigabit speed, so he then hooked up the Netgear Nighthawk router he brought with him which worked perfectly. 

 

If for some reason in Atlanta they tell you that you have to use their router, since there is absolutely nothing in any contract you have with Comcast to the contrary, just hook up your router after he leaves.

I figured I'd do the same thing, however when I did the other night it would not pull an IP from the Comcast modem. I configured the Cisco 2821's WAN interface to use "ip address dhcp", and then set the route to be "ip route 0.0.0.0 0.0.0.0 dhcp 1". Just to provide a short backstory, this same setting works for the Blast 300. I also tried setting it to the static address that their NightHawk had along with the next hop it showed, and same problem can't even ping the next hop. 

 

The rep I spoke with last night tried to make it abundantly clear they don't allow this kind of configuration. Which is ridiculous, also I noticed a lot of people on here get static IPs, where do they get this information from? I'd prefer a static IP, what packages come with that?

FWIW, the modem needs to be powercycled each and every time that the device that is being connected to it is changed.

Yeah, I can confirm the modem was powercycled, followed by the router and still no dice. Appreciate the suggestion, open to any more if anyone else has run into this problem?
