Comcast has several different packages with standard speed rates ranging from about 10 Mbps for the most economical to the highest-performing 2,000 Mbps. All of the plans deliver enough internet oomph for web and streaming video, though hardcore gamers and multi-user households will want Comcast’s higher-performing services.

Slow Upload Speeds
Hey /r/Comcast_Xfinity,
I've been experiencing slow upload speeds for the last few months and it's been impossible to troubleshoot with Comcast via phone or chat. My download speeds are perfectly fine and I have zero complaints - it's only the upload speed. I didn't have any issues with my upload speeds prior to this and my service level hasn't changed. My desktop is hard wired in and the connection path is: coaxial - modem (SVG2482 AC) - router (R7000) - desktop. Bridge mode is enabled and WiFi is disabled on my modem
My current service states download speeds up to 150 Mbps and upload speeds up to 20 Mbps but the upload speed is anywhere between 2 - 5 Mbps when using non Xfinity speed tests like TestMy.net or Google
The problem I constantly have with support (besides the constant reboot modem ad nauseam and a new one from today: run disk clean up) is how Comcast only recognizes their speed test and the results that show on their page are not what actually occur. It's near impossible to stream at an acceptable bitrate now and the stream health graph looks like the top half of a Richter scale when an earthquake occurs
Here's a screenshot of my Upstream: https://i.imgur.com/nEeyVbb.png
Hoping someone on this subreddit can help because I really don't want to pay BS technician fees when it can actually be solved remotely by a competent analyst
Thanks in advance!

Reliable high speeds, widespread availability
How We Reviewed Comcast Xfinity
6 speed plans evaluated
Comcast Xfinity Review
If Comcast Xfinity is the main — or only — cable internet option where you live, then we have good news for you: Comcast is one of the best internet service providers (ISPs) in the US. It offers a wide variety of plans, with download speeds ranging from 25 to 2,000 megabytes per second (Mbps). That’s among the fastest on the market. Comcast is also the most widespread provider, with far-reaching service in 39 states and Washington DC.
To top it off, Comcast is ranked among the most reliable ISPs. This means that you’re a lot more likely to actually receive the internet speeds you pay for. Xfinity takes second place nationwide for its ability to deliver on advertised speeds (scoring just below Optimum).
The Claim
Comcast claims that Xfinity Internet delivers the most reliable high-speed internet and Wi-Fi for all devices, all the time.
Is it true?
Yes. Technically, we can’t call Comcast the most reliable provider, as Optimum eked past it in the Federal Communication Commission’s (FCC’s) latest report. But Xfinity passes the 80/95 benchmark, meaning that at least 80% of customers receive advertised speeds 95% of the time. In terms of reliability, Xfinity beats most cable internet providers — and it far surpasses DSL and satellite options.
It’s also worth mentioning that, while Optimum took home gold for reliability, it only serves four states. Xfinity Internet is available in 39. This means that in every state Comcast serves — besides Connecticut, New Jersey, New York, and Pennsylvania — it really is the most reliable option. It’s also likely to be one of the fastest. In 2017, the internet performance ratings site SpeedTest.net ranked Xfinity as the fastest internet provider nationwide. Available speeds vary by location, so be sure to use our ZIP code tool to check plans in your area.

Features
Reliably fast internet
Xfinity Internet not only promises some of the fastest speeds available — from 25 Mbps up to 2,000 Mbps — but it also does a great job keeping that promise. Comcast customers are more likely to actually experience the download speeds they pay for than those with other internet service providers. Proven reliability is the reason Xfinity was rated Fastest Internet Service Provider by both SpeedTest and Netflix in 2017.
Generous data allowance
Even though Xfinity technically has a data cap, most customers will never have to worry about maxing out their internet usage. Comcast sets its limit at 1 TB per month in most states; for context, two people can play online games 24 hours per day for 30 days straight and still have enough data left over to watch all 629 episodes of 'The Simpsons' in high-def. In other words, Xfinity will feel unlimited to most people.
If your household does use more than 1 TB of data per month — think multiple people streaming on multiple devices every day — Comcast has a solution. The company offers an Unlimited Data Option for an extra $50 per month. However, Comcast recommends signing into your account to monitor your personal data usage before making the upgrade. You may find that 1 TB of data stretches further than you think.
Flexible data plan
Xfinity also offers money-saving data plans for light internet users. If you only use Wi-Fi to check email and surf the web (rather than to stream video or online game), then you may be eligible to enroll in Comcast’s Flexible Data Option. This plan credits $5 back each month to customers who use less than 5 GB of data. Before enrolling, though, be sure to verify that your data usage truly falls below that 5 GB mark — if not, you’ll be charged $1 for each extra gigabyte, up to $200 per month.
Ultra high-speed network options
Comcast is currently rolling out Gig-speed internet — an ultra-fast fiber internet option that can reach download speeds of up to 2,000 Mbps (2 Gbps). The catch? Its Gig-speed connection is still in its early stages, and it's only available in a handful of cities. It’s also costly: Xfinity’s fastest fiber option rings in at a stunning $300 per month, with $500 installation and $500 activation fees. The lower-tier, 1 Gbps plan costs $110 per month (with a two-year agreement) — which is more reasonable, but still spendier than most cable internet plans.
Possible drawbacksCustomer service
ISPs don't rate highly for customer service, and Comcast is no exception. It has a reputation for long wait times to reach a representative and difficulty disconnecting services. The American Customer Satisfaction Index, which conducts thousands of customer surveys annually, ranks Comcast as eighth best out of 12 providers. J.D. Power, another independent third party, gave it a ranking of 2/5 in customer satisfaction in the North Central, South, and East regions. That said, Comcast is striving to make improvements by hiring more representatives and creating appointment slots to reduce hold times, so customers should see improvements in the future.
Expensive
Xfinity isn’t always the best value when compared to the competition. For instance, $45 per month gets you up to 150 Mbps with Xfinity but up to 200 Mbps with Charter Spectrum. Of course, it’s worth remembering that Xfinity is more likely to meet its promised speeds than many other providers — so paying less with another ISP may still mean slower internet.
The Competition
Comcast Xfinity vs. Cox Communications
Cox Communications fares better than Comcast Xfinity when it comes to customer service. However, Xfinity plans generally offer better value than Cox's. Both companies’ base internet tiers start at $30 per month. (Note: If you choose a one-year contract, your Xfinity Internet plan starts at $20 per month.) With Xfinity, that $30 gets you 25 Mbps download speeds, while with Cox it only gets you 10 Mbps.
Comcast Xfinity vs. AT&T Internet![]()
AT&T Internet is one of our favorite internet service providers, and it also earned top marks in J.D. Power’s customer satisfaction awards. As with all ISPs, plans and pricing vary by location — but most people will get a little more bang for their buck with AT&T. For example, a $40 plan from AT&T starts at up to 50 Mbps (reaching up to 100 Mbps for $40 in some areas), while a $30 Comcast no-contract plan only gets you 25 Mbps.
![]() Comcast Xfinity vs. Charter Spectrum
Charter Spectrum internet plans start at 100 Mbps, while Xfinity plans start at just 25 Mbps. For those higher service tiers, Spectrum tends to be a bit more affordable (between $5 and $20 less than Comcast). It also doesn’t impose data caps and will pay up to $500 to buy you out of your current contract. That said, Spectrum speeds don’t reach Xfinity’s highest 2 Gbps speeds. If you live in an internet-loving household and need high-capacity downloading speeds, Comcast Xfinity is likely a better bet.
Comcast Xfinity FAQWhere is Comcast Xfinity available?

What is the fastest Xfinity internet speed?
In most areas, Xfinity offers internet speeds between 25 and 250 Mbps. Prices range from $30 to $60 per month for these plans if you choose the no term agreement option. Certain areas also have access to Gig-speed internet, Comcast’s ultra-fast fiber internet option. Gig-speed offers downloading speeds up to 2,000 Mbps — but it’s less accessible and much more expensive than traditional cable internet. To see which plans are available in your area, use our ZIP check tool.
What Comcast Xfinity speed should I be getting?
The right internet speed for your household depends on how many devices you use, how often you’re on them, and what activities you primarily do on the internet. The table below can serve as a guideline to get you started. Once you’re signed up, we also recommend checking data usage in your Xfinity user account. This is a good way to ensure that you’re not in danger of exceeding data limits or paying for more speed than you actually need.
What is the difference between Comcast and Xfinity?
There isn’t one. Xfinity is owned by Comcast — it’s the company’s cable TV, internet, and phone branch. The two names are sometimes used interchangeably when talking about these services. You may also see it called “Comcast Xfinity” or “Xfinity by Comcast.” All names refer the same suite of TV, phone, and internet services provided by Comcast.
The Bottom Line
The first step in choosing an ISP is to see which companies are available in your area and to compare plans and pricing offered by those companies. If Comcast Xfinity has service where you live, then it’s likely one of your best options. With multiple speed tiers, decent value, and certified reliability, Comcast tops much of the competition. And while customer support has been a sticking point for the company, efforts to improve its service point toward a more positive customer experience in the future.
