Comcast internet upload speeds
I have the 100 Mbps download plan. My upload seems to be capped at 5 Mbps.
The upload speed is making video conferencing and sharing presentations a pain. My voice often breaks up for others on the call when I'm presenting.
Is the 5 Mbps what everyone else is getting? Does anyone know if there is a faster upload speed option available?
Comcast doesn't have any info on upload speeds on their website (even after I log into my account.) If they have it, it's well hidden. Trying to get in touch with a human is almost impossible and the virtual assistant is no help.
emaxxman FWIW, my 100 Mbps rated download speed almost always exceeds its rating. I get 115 to 120 all the time so I know my lines, modem, and router are fine.
5 up is the speed you are supposed to get with 100 down.
Blast is what will give you about 10 up. I think they just announced a newer service even higher that's available to consumers.
From there you need to start thinking symmetrical and you're in Comcast for Business territory. The speeds are all there and available, just get ready for the price involved.
GC I was recently forced to upgrade to 300MB Blast... hated that I went from $49.99 a month promo up to $69.99 promo for the blast for 2 years...but it was all they would do for me. Anyhow.. my speed went from 100 down to 300 and up from 5 to 10... so at least it was a decent speed improvement.
GrascalDepending on whatever else is going on, 5 Mbps upload should be sufficient for video conferencing. Now if 3 or 4 people are video conferencing simultaneously, that could be an issue. I have the 100/5 plan from Comcast and have no issues whatsoever.
If you're using Wi-Fi, I'd recommend going to a wired connection and seeing if that makes a difference. Also, if your computer has insufficient resources (not enough RAM, slower processor, too many programs running simultaneously, etc.) this will also impact the quality of video conferencing.
theolgamer I'm thinking either my modem is on the fritz or there is noise in the line that is causing my drops. My son was taking online courses (but that's also mostly download) but he's done now.
speedtest.net shows my connection has intermittent slowness.
My laptop is about a year old - Surface laptop, core i7, 16 gigs of ram.
Desktop is ryzen 7, 16 gigs
Both are plenty fast so I know the hw is not the issue. I'm also hardwired into the router for both laptop and desktop.
I ordered a new modem from Amazon - Netgear CM700. Comcast says there is nothing wrong with the connection so I'll try replacing the modem first.
My 12 month promo ended so I went for 39.99 to 59.99. Considering switching to Internet and TV. Even after the promo price ends on that, It'll still be about $60 cheaper than Comcast Internet + Directv.
This is the first time I've ever had issues with my ISP (had DSL for years and Comcast for almost 2 years.) Wouldn't be a big deal if I wasn't working full-time from home these days.
I will say that the upload speed is paltry just on principle alone. My daughter had 60 Mbps down (Cox Cable in Rhode Island) and that had 15 Mbps up.
Outside of work, the upload speed matters when I'm uploading a day's worth of photos (not that I go anywhere these days) to the cloud. At 5mpbs, it still takes a long time.
Agreed computer hardware is not the issue. Good luck with the new modem, are you sure it's not a router issue?
As an aside, I had trouble with Comcast at work...and I'm pretty sure they lied to us or they truly have no idea. For some reason the phone tech had in the system that we had our own modem despite paying the $10/mo. Rental fee. Up until that point, he said there's nothing wrong with the line or modem. It wasn't until I corrected him and gave the model number of the unit that he said there is signal loss...so they dispatched a tech to fix it. The tech confirmed there was no signal loss and that the modem needed a new configuration file.
It could be the router but the wireless connections dont seem to drop. Just the speed. I was looking to upgrade to a mesh system ( because even though my house isnt that big I still have dead spots. )
Figured I'd do one device at a time.
Steve Depending upon how old your lines are, that could also be an issue if everyone in your household keeps dropping. We had that issue and had our outside line replaced. Turns out the wire was bad, but also the connection piece st the pole was an old adapter.
@Mikey - there was a section of the line at the pole that was exposed and really oxidized when I first signed up for the service. The tech cut the bad part off and reattached the line.
I'll call them tomorrow if I can get some free time.
Simple change you can make at your house to make sure you cable modem has the most signal. For the line that comes into the house make sure there is the least amount of splitters between your modem and the street. The more splitters you have the lower the signal. I like to use a 2 way for the line that comes into the house. 1 to the modem and the other to TVs. If there is more then 1 TV then I split that side into multiple. This means you only have 3.5db of loss on the modem side. I’ve seen where people have a modem and 7 TVs and use 1 8way splitter which gives you 10.5db loss to the modem. Or people have way too many splitters. Also make sure all you cable in the house is all RG6. It’s thicker then older RG59 cable. If you have RG59 replace it. The connectors also matter. Bad or poorly installed connectors will cause signal loss. Too many splices can also cause issues. Best bet is one piece of cable with no splices.
video calls go much smoother if you use the ethernet wire conected from the pc or laptop directly to the router and bypass the wireless connection.
tryingtohelp A tech is supposed to call me tomorrow. Finally got through to a live person on Sunday. They said that they found a signal loss (must be intermittent) on the line.
I only have cable for Internet. All of the coax in my house was is used up for Directv. When I got Xfinity, I ran a dedicated line from the box outside, through the garage directly to the office. The run from the box is probably less than 30 feet. So no splitters, etc. to create noise or signal loss.
My laptop is wired directly to the router via its docking station. The router is less than 2 feet away so even going wireless shouldn't be an issue.
I got a new router on Saturday so I know it's not the router (was at Costco and said, why not?) Still using the old modem (which I think is fine.) Even though my house isn't that big, the living room and 3 season room were two big deadspots. Using the old router as a wireless AP. Strong wifi everywhere now.
Tech just came and replaced my entire line from the house to the street. Apparently it was a series of splices. Surprised it worked as well as did for the time I've had it.
Speedtest is showing 120 mpbs down with no packet loss. I was getting as high as 20% packet loss based on the test history.
iJay That's good to hear. With the fresh cable run and new router, you should be all set for years!
It's been smoooooth running. So nice when things just work.
Just ordered the TV+Internet service. Year 1 charge is less than what I pay for Directv alone and I get the bonus of having my internet service upgraded to 200/10.
My xfinity bill went up $25 this month as my contract expired. I went to the Port Murray office for an explanation, they were unable to answer me. They have me an 800 number (the "retention specialists") to call. I have tried to call and speak to a person, they disconnect me every time. Anyone have a number that works? This is so ____ frustrating. Thanks for any help.

Greg Good luck with Xfinity they don't give the package deals like they used to . Last year I had to give up HBO , NFL Redzone channel , TCM , CMT among a few other channels just to get a decent rate .They also keep trying to get me to rent their junk X-1 cable box and their modem/router so they can use my house as a wi-fi hot spot .They used to offer decent discounts , now it's like pulling teeth just to try to keep your service the same at a reasonable price .

May '20..... cousin said it, and hit the nail right on the head.
I had one Comcast tech at the house, oh like 6 years ago, and we had bad tv problems. He said, the outside cable was rotted and old, and would come back with help to replace it. It solved our problems for tv quality.....
Now, we have the "Boost" speeds, and two recorder boxes; with 7 tv's and 4 computers. The main box controls the signal on the other six boxes, and it kept cutting off all the other tv's in the house. The tech came out, and checked with his signal meter, and said there were too many splices in the cable system, so he added amplifiers and respliced three tv's.
After the fact, and a 5 hour $h!t Show, he found that the HDMI cable to the tv was bad. "That was the Whole Problem!"
I told him, "All those splices and t taps ( splitters ) were installed by Comcast people; so how did they become My Splitters?"
They billed me $40.00 too!
