Singapore is 278 square miles small

Re: Got my Gigabit Pro and LOVING it!

I also live in south FL.    I don't have the gigabit pro I signed up for the Gigabit.  I average around 200 Mbps on the Gigabit connection.  Highest I've seen was 400 but that was just one time I did the speed test.  I think part of the problem is this Technicolor Cable Gateway.  Seems really lacking in quality.  Also for some reason I have to clone the mac address of my PC to the router in order for the Gateway to give the router an IP.

Re: Got my Gigabit Pro and LOVING it!

I was denied for gigabit pro because I’m 1900 ft from the splice and you need to be under 1700ft away. They said if someone in between me and the splice signs up I would qualify. Seems pretty dumb, because I’m basically on the complete opposite side of the splice, so if someone in between me and the splice starts the process and then I sign up, they may as well just trench the whole street and call it a day.

Also, at the same time I was denied I asked about gigabit service and I was told it should be launching on 7/5/2017. Let’s hope that date is true, because anyone in my development of 1500+ homes can already sign up for gigapower from AT&T at a cost of only $80/month. AT&T already laid fiber a year ago, so at this point Comcast is behind the 8 ball.

If anyone within Comcast is curious, I live inside Winston Trails in Lake Worth, FL 33463. I would think it would be to Comcast’s advantage to start making things happen. Our development only renewed our bulk contract with Comcast for 5 years...

Re: Got my Gigabit Pro and LOVING it!

Hi pcmichael! At this time you have to be within 1/3 of the fiber headend. We will evaluate extending that length out at a later time. However there is no eta on when/if we'll do that.

Re: Got my Gigabit Pro and LOVING it!

Yes, I understand that... but I’m also trying to make Comcast aware that our entire development now has AT&T fiber running in front of our houses and it is lit, meaning everyone is eligible to get all AT&T fiber based services. Comcast stands to start losing customers if they don’t start offering competing services. It would seem it would be in Comcast’s best interest if someone a little higher up takes another look at our development (some 1500 single family homes) and starts formulating a game plan sooner, rather then later.

Re: Gigabit Internet Speed

Hello,

 

My address qualifies for Gigabit internet and I ordered it via the 800 number. The phone operator informed me that I cannot use my own equipment. However, I have a Motorola MB8600 that is listed as approved/supported for Xfinity Gigabit internet. Is there any other reason I can't use my own equipment? It would save me a service visit fee as well as equipment rental costs.

 

Thanks!

Don't take anything anyone, whether they be on this or another forum, telephone, or online chat, tells you as definitive until you go to order it. I had 2 representatives via chat, 1 via phone, and a friend of mine, who is a senior IT technician in my system tell me I could use my own modem. Bought an SB8200 and called, at which time I was told I couldn't use my own modem.  I E-mailed executive VP of Engineering for my region, and he told me the same thing -- that I couldn't use my own.

 

Aparently in some areas you can, though.

Re: Gigabit Internet Speed

FWIW. I believe the official thing is they still regard Gig 3.1 as a trial and that is why they want you to use their equipment. You only have to read a few threads on DSL reports forum to see that some are getting their owned devices provisioned OK.

If I had bought my own, think I would be tempted to connect it after the initial install. (if they won't provision it straight off).Of course you run the risk of something going wrong with the provisioning or perhaps not getting the full speed you were before and maybe problems getting the $10 rental fee off the account after returning their gear.

Still, if the worst comes to the worst, you can always stick their gear back on...Just my 2cents.

Re: Gigabit Internet Speed

The VP did give me an explanation, which I completely understand their argument.  However, I know people who have some of their devices configured for static ip addresses.  Myself; everythng but my Roku, computers, and mobile devices are static.  Kind of makes it hard to login to a camera or AVR or printer if you don't know what the ip address is.

 

Their gateway can't even be put into bridge mode.  You're basically turning your private network over to them.

 

Yes, the time will come when they allow other manufaturers' equipment (they have to certify other manufacturers' equipment for 1Gig speeds first, for which they have no timeline)  Until then, though, how many people will decide that their current package is fine for them?

Re: Gigabit Internet Speed

When I had my 1 Gig install last year, they provided me with the standard Technicolor TC-4400-CMT modem and a Neatgear Nighthawk X6 router.  I asked whether I could use my own router and was told "No" and "Other routers probably wouldn't work as well anyway."

 

A few weeks later I bought a Linksys Velop routing system and replaced the Netgear.  There were absolutely no problems, My Velop is at least as fast as their Nighthawk and I can configure it the way I want to.

 

I just put their Nighthawk back in the box and put it up in a closet because I know sometime at a later date they're going to want it back.

Re: Gigabit Internet Speed

Yes Alan, no reason a decent router/system shouldn't work for you. Egnisn has an XB6 gateway though and from what I understand they won't allow bridge mode yet. I was just suggesting connecting his own already approved D3.1 modem to possibly save the $10 rental and make the network more configurable. Personally I'd do it... Smiley Happy

Re: Gigabit Internet Speed

I just got this service installed yesterday. I previously had Extreme 150 and they charged $60 for a Comcast tech to come out and juts verify that I had the right equipment for the job. He didn't do much other than switching out an old Comcast 2-way switch and put an amplifier in as I apparently was getting a weak signal.

 

I currently am using a Motorola MB8600 along with an Asus RT-AC68U. I quickly found out that I needed to turn off dynamic QoS as well as traffic analyzer in order to get the full speeds. Everything is working as expected now.

 

Just hope that Comcast comes down on the pricing as I now pay $189 for Gigabit plus unlimited data which should be a given with Gigabit internet at $139.

Problem Solver

Re: Gigabit Internet Speed

Very important advice you gave Visism.   You DO need to turn OFF any traffic analyzer in your router, no matter what the brand in order to achieve the Gigabit speeds you are paying for.  I've never heard of a Comcast installer explaining that to the customer.  And I've heard of instances with the Nighthawk routers they provide customers where the customer will call Comcast complaining his maximum download speeds has dropped to 450 Mpbs  The installer comes back, sees the poor download speeds and provides a NEW Nighthawk, everything looks great.  He leaves, the customer turns the traffic analyzer back on and BOOM,   poor download speeds. It THEN dawns on the customer what's going on and when the analyzer function is turned off the Gigabit speed is back.  I guess most of the Comcast installers didn't know of this

 

(By the way, that customer I was talking about up there was me)

I went into my local service center to swap out my STB, and they told me that within the past month they started allowing owned cable modems on the 1Gig plan.  Keeping my same TV package and upgrading my internet to 1Gig will cost me an additional <$10 per month (for 1 year).  Installation is $40 (to come out and verify my levels and speeds)(still won't let us do self installs yet), give me a new STB (SSD), and be on his way.

 

Last night, speeds were ~850Mbps, while this morning they were running at ~950Mbps.

 

Comcast has finally got me to be a happy camper.

Re: 1 gigabit availability

I've got 1Gbps through Comast (and they quote 35 Mbps but always shows up between 41-42.xx Mbps)

 

I've learned a lot in the past two weeks... YOU NEED GOOGLE CHROME TO REACH TOP SPEEDS

Firefox and IE won't get past 800 Mbps.

 

Doing an IPv6 as opposed to IPv4 DOES NOT WORK. You will get ridiculous results under 1Mbps, it's not accurate. 

ALWAYS DO IPv4 SPEEDTESTS.

 

DO NOT MESS WITH THE ROUTER SETTINGS IF YOU DO NOT KNOW WHAT YOU ARE DOING!

 

For some reason if you turn on Access Control in the Nighthawk x6 (The router provided for FREE with $10/mo modem rental for gigabit PRO (1Gbps d/l  /  35 Mbps u/l), you will ALWAYS GET BELOW 500Mbps.

 

So any tweaking of the factory settings will throw your speeds off (unless you know what you are doing or have the comcast tech walk you through it).

 

Talk to the "Wireless Gateway" people for tech service. NEVER TALK TO THE OUTSOURCED Comcast reps --- THEY KNOW NOTHING!

 

Finally I think I may be reaching my limits --- 965.31 Mbps download 41.42 Mbps upload.

 

On a final note when I login to my xfinity account and I look at the "internet plan" it states that I have "Gigabit Internet" although my download speed is: 986.5 Mbps and upload speed of: 35 Mbps... hmmmmm

I'll have to give Chrome a try.  I use Edge, and am always at 850-875/~38 in the evenings and ~948/~41 in the mornings.  Ping times are always 8-11ms.

 

Definitely turn off IPv6 in your router.  My ping times for IPv6 are always 75-80ms and the speeds are SIGNIFICANTLY slower as compared to IPv4.  IPv6 also caused several of my cameras to go offline.

 

In my Linksys, I had to turn off Prioritization to achieve full speeds.  With it on, I was looking at <200Mbps.

 

My account indicates the same 986.5/35.

Re: Gigabit Internet Speed

I recently got Gigabit installed here in Dublin, CA on DOCSIS 3.1 modem.  Immediately after the install, the speeds were around 600 MB/32 up when directly connected to router and it was fluctuating to 300MB.  A far cry from provisioned 982/32 MB.  

 

After tech left, new modem has been nightmare.  The download speeds are any where from 1.29 Mbps to 300 Mbps with multiple outages.  My WiFi (Eero) shows more red (complete rarity when we had previously Blast pro 200+ Mb line w/ DOCSIS 3.0)

 

Had a chat session with tech support, they could not figure out the problem either.  Now waiting for another tech visit next week.  

 

Overall not happy to pay more, pay install fee for "Gigabit Service" and not have "working" service....

Hi there,

 

Just self-installed a Motorola MB8600* for Gigabit at my home yesterday. http://speedtest.xfinity.com/ over a wired connection** is showing only 75-80 mbps download*** consistently all day yesterday and today. Assistance in getting gigabit speeds would be great, please!

 

Thanks!

 

* "Motorola Ultra Fast DOCSIS 3.1 Cable Modem, Model MB8600, plus 32x8 DOCSIS 3.0, Certified by Comcast XFINITY".

** Tried both directly connected to modem and via a router, on gig ethernet.

*** Upload speed seems as-advertised, around 40mpbs.

Contributor

Re: Gigabit Internet Speed

If you haven't, I'd try another device to see if you get same result (ie plug in a different pc and test).
Then, I'd confirm with tech support they provisioned your speeds correctly.
I had to have a tech come out and do something outside (something about switching an outlet to allow the higher speeds over the coax).
Good luck.

Re: Gigabit Internet Speed

Thanks for the suggestion. I get the same result under the same conditions on a second PC.

 

Recommendations for the best way to contact them and ask about provisioning? I had seen a number of Comcast employees responding on these forums and was hoping that talking here was an option, since live chat/phone always take a very a long time.

Re: Gigabit Internet Speed

I transitioned over to Gigabit today and was of the impression that it would require a new gateway.  The Xfinity retail store gave me a Technicolor DPC3941T, which I believe is the exact same modem I already have (I'm at work and haven't gone home to check).  It explicitly says on the device that it is DOCSIS3.0.  Does Gigabit not require DOCSIS 3.1?  If so, how will I get the speed I'm paying for out of the modem they gave me?

Re: Gigabit Internet Speed

Since everyone at Comcast seems to be clueless about the actual hardware I need, but they do seem to agree that I have the wrong hardware, do you have information on the equipment they need to get to me for this installation?  I know it needs to be DOCSIS 3.1, but I can't seem to find anything on their website that talks about their leased equipment.  I can find information on retail equipment I can purchase.

Discovered Throttle point for Gigabit Service with Nighthawk router

Hey All,

 

For those of you who have recently upgraded to the Gigabit service with Xfinity and received the combo Technicolor modem and Nighthawk wifi-router, this can apply to you.

 

One of the settings in the Nighthawk router is Dynamic QoS.  The following is from the Router help center:

Dynamic QoS improves online gaming and online streaming quality by prioritizing Internet bandwidth usage. When the router detects online gaming and online streaming traffic, the router tries to limit background traffic such as BitTorrent or FTP downloads to improve gaming and streaming. 

There are two settings for configuring your Internet Bandwidth:

Internet Bandwidth - Let Speedtest detect my Internet bandwidth (recommended): Accurate Internet bandwidth is required for Dynamic QoS to work properly. The router automatically runs Speedtest the first time you enable Dynamic QoS. Click the Speedtest button to recheck your bandwidth. Avoid any Internet activity while Speedtest is running.

 

Internet Bandwidth - I want to define my internet Bandwidth: If you know your Internet bandwidth, you can enter it manually here. The maximum value is 1000.00.

 

I have found that when this setting is enabled it will limit the overall Up\Down speeds based on what it is configured for.  Now the Speedtest option, unfortunately, doesn't let you choose what host to connect to so for me it was only pulling 260 Mbps Down and 30 Mbps Up.  So when I run Speedtest on my PC I end up getting roughly the same results. Considering that my actual range in usually 900+ up and 35+ that is quite throttled down.  However, if I set the Bandwidth manually to 900 Down and 30 Up, then on my speedtest I end up getting 500+ Down and 30ish Up.  So the bandwidth is still throttled but is significantly higher.

 

If you have any questions let me know and I will try to answer them the best I can.

 

Thank you, 

John

Re: Discovered Throttle point for Gigabit Service with Nighthawk router

You need a DOCSIS 3.1 modem for gigabit.

Re: Discovered Throttle point for Gigabit Service with Nighthawk router

Have an appointment for gigabit install tomorrow. I have a few questions -

 

1. There is no new cabling etc involved right?

2. Does the speed depend on distance from the node (like ADSL) or am I guaranteed the advertised speeds?

3. Does Comcast supply a modem as well as wifi AC router? Earlier in thread people said they give you a Nighthawk X6. Can someone confirm this as well as that total rental for both will be $10?

 

Thanks

Re: Discovered Throttle point for Gigabit Service with Nighthawk router

Hi Adent,

 

Here's what happened in my case.

 

There were two different trucks that showed up for my install.  The first crew checked the cabling.  They did NOT need to install anything additional at all, they just went outside to make sure that all signal levels were good.  They did change a couple of connectors and said that everything was OK.

The second crew installed my modem and the Nighthawk router.  One of them made a mysterious call to a secret Comcast number and activated the modem.  

I think if your signals are OK you should get the advertised speed (I certainly did.)  There's no worry about "distance from a node."  

As to your final question, as I said above I received a Technicolor modem as well as a Nighthawk X6.  Since I have Comcast telephone service I kept my old Comcast gateway for that, so I have THREE Comcast devices for $10 a month total price. 

Also, please realize that my install was a year ago, and things may have changed since.

To add to Alan's post, they have started giving out the new XB6 3.1 gateway now, so you may get one of those, for the same 10 bucks...

Thanks. Does the gateway replace both the router and cable modem? I prefer separate devices - modem + router and from what I read both th emodem and Nighthawk router are highly rated. I also read while searching for info that people say the XB6 is not giving them the same speeds.

 

"As stated, I just got the XB6 gateway installed and so far, not happy with the results (as compared to what others are getting). Speeds vary from 600-800 down (inconsistent) however, 30 up pretty consistently. The wireless range su_cks to say the least and was only ale to get about 300-400 down out of (standing next to the gateway). There is also no way for me to set the gateway to bridge mode which is a really big fail. I was also told that I cannot use my own modem (I had purchased an SB8200 in anticipation but haven't tried it). I know the gigabit is in initial rollout stage here in Utah and there is probably a ways to go. Let me know if you have any questions about it." - from another forum.

 

Will see what I get.
