We have Xfinity for our internet and are under the assumption we are paying for 100 mbps. While streaming tv we noticed lots of buffering.I did a speed test and found we are only running at a download speed of 33.54 mbps. We will be calling Xfinity but I was wondering if anyone here are having or have had the same problems. If you have did you find a resolution to this annoying problem?l

Try turning the TV off, turning your computer on with no television or streaming services running, and checking speedtest.net on a browser. It's possible that you ARE getting speeds up to 100mbps. Also try connecting to a different server with the speedtest. And remember they promise "up to" 100mbps, not "exactly" 100mbps. So if it's in the 80's without streaming, it's probably fine. If you have a lot of devices connected to your modem/router it'll slow them all down too since they're all sharing the same connection. It shouldn't be as low as 34mbps. Are you using the xfi gateway, or some other xfinity-provided modem/router? Or is it one you purchased elsewhere? Your connection will never be better than the capacity of your modem.

Every time I test my Xfinity speed, it exceeds their quoted speed. There are many factors that can affect internet speed. The advice in the pervious post is spot on.

Also, are you connected via WiFi? It will not be as fast using WiFi and where you are located reference your WiFi router makes a BIG difference. Get up real close to the router and watch your speeds increase....or better yet connect via Ethernet cable for an accurate speed test.

Never hurts to shut down the router, then reboot the modem. Once the modem is up and connected, restart the router. Always seems to improve my internet speeds. I have Xfinity also, but with a separate router. If you are using the Xfinity gateway (modem and router in one unit) then just shut it down and restart it after a minute.

I have xfinity, and I am paying for 250mbps, but the most I could get was around 80mbps, and sometimes 100 on the download. Had a service call, and the tech told me that, even though I had 250 service, 80 mbps wasn't bad because it was wireless. I told him that I could get 250 at my son's home, so that didn't make sense. We have a MacBook pro retina, and a ipad pro, not exactly slow machines. He said that he would install another modem/router. I'm now averaging between 290/300.

Promised speed is with an ethernet connection. Of course, they don't lead with that fact.

Promised WiFi speed is not with an ethernet connection. The problem is that you're bypassing their recommended "buy our Comcast Cable TV" by using a streaming service and device. Your WiFi will - or should be - at the speeds advertised. That's why I said to try it without the TV on, and just using your laptop or computer with no streaming. The WiFi connection should be coming to your house just fine. It's what you do with the connection that would slow it down.

You definitely need a router that can accommodate the promised d/l speed. The speed of the service will never be faster than the speed capacity of your modem/router.

I believe speed can be impacted by your device. My computer tests around 70 mps download speed, but my Kindle Fire HD tests at over 100. My service is promised at 100.

O.k sitting in the same room where my firestick is having buffering problems because it's only at 34 mbps I did a speed test on my tablet and it registered 87 mbps. Is it possible there's a problem with the firestick?

What modem do you have? Yours? Comcasts? Model?

We have a router/modem recommended by Xfinity. We bought it at Best Buy and it's considered an upgrade from xfinity's equipment. I'm not home now and don't know the model

We have CenturyLink fiber optic service and promised speed is measured as what's delivered to my router. They came out and measured because I questioned the speed and found 40 Mbs delivered to the router, but 20 Mbs delivered to my computer only 20 feet away. All CenturyLink hardware.

We have 25 Mbps and can stream 3 TV'S at one and One iMac and on Samsung Tab or Pad??? We use a Roku. I had purchased the latest Firestick and sent it back because while all Roku Program worked fine the Firestick shows constantly buffered. I wish you luck bud, it can be frustrating.

We switched to a Motorola Modem which didn't really improve the performance but knocked something off the bill. It's $19.99 until June or July with Comcast.

I'm just kidding now, IT'S BECAUSE YOU ARE SO FAR AWAY THAT THE INTERNET IS SLOW. THE PEOPLE IN BROWNWOOD ARE GETTING ALL THE FAST INTERNET. IT WILL BE BETTER ONCE THE NEW BRIDGE IS INSTALLED!
